  • Recombinant Antibodies for GPCRs: A Challenge to the Community | Dr. GPCR Ecosystem

    Dr. Alexander Ball of GeneTex on the recombinant platform and validation strategy behind a challenge to GPCR researchers. Free live webinar, June 25. < Back to Webinars 📅 Thursday, June 25, 2026 at 11:00:00 AM EDT 🤝 Webinar in collaboration with: GeneTex Recombinant Antibodies for GPCRs: A Challenge to the Community Test them in your lab. Tell GeneTex what works and what doesn't. A reagent gap that holds back the biology GPCR activity is targeted by one-third of all FDA-approved drugs. Yet much remains to be learned about how these 800-plus receptors are expressed and how they function in living systems. Part of the gap is biology. Multipass transmembrane proteins are genuinely difficult targets. Part of the gap is the reagents. Reliable antibodies for human GPCRs are scarce, and without them, basic questions about expression and physiological function stay out of reach. Producing specific antibodies for human GPCRs is a formidable job. Expression levels in common cell lines are often low. Identifying an immunoreactive antigen sequence that is specific for a single receptor and detectable across applications is difficult on its own. The literature often disagrees on which antibodies actually work. Proving specificity for the intended GPCR is rarely straightforward. GeneTex is tackling that problem with a high-throughput recombinant antibody platform paired with enhanced validation strategies. The approach has already generated more than 300 recombinant monoclonal antibodies against almost 200 human GPCRs, and the catalog keeps growing. Inside the platform The production workflow is built to detect promising clones early and to hold specificity, scalability, and consistency steady once those clones are selected. Dr. Ball will walk through how the recombinant platform was built, what it takes to produce specific antibodies against multipass transmembrane targets including GPCRs at scale, and how the workflow handles the realities of low endogenous expression and tight specificity requirements. Validation that earns the catalog its place Every antibody is characterized through a prioritized validation set: CRISPR-based knockout and knockdown protocols, endogenous expression detection, cell fractionation, comparable antibody testing, and application-specific testing. When feasible, GeneTex uses VirDTM-GPCR arrays (CDI Labs, Mayagüez, PR), which present a nearly comprehensive library of human non-olfactory GPCRs individually expressed on herpes simplex virion envelopes for cross-reactivity screening. Dr. Ball will walk through each, explain why KO/KD testing is prioritized, and show how the validation data is shared with researchers. The challenge: test them in your lab This is the goal of the Dr. GPCR x GeneTex partnership. GeneTex is offering free samples of the recombinant antibodies to GPCR researchers in exchange for structured feedback, positive or negative. As Dr. Ball puts it in his own words, the primary goal is to get these reagents tested and evaluated by GPCR researchers. That is how a catalog earns the trust of the community, and how the community ends up with reagents it can actually rely on. Dr. Ball will explain how the challenge works, who it is for, and how to request samples. Speaker Dr. Alexander Ball , MD, Senior Scientist, GeneTex, Inc. Dr. Ball has been with GeneTex since 2012 and leads the company's enhanced antibody validation initiative. He earned an M.D. from the University of Southern California School of Medicine and completed internal medicine training at California Pacific Medical Center in San Francisco. He transitioned from clinical medicine to academic research at UC Irvine, where he worked on protein complexes mediating chromosome dynamics. At GeneTex, that background shapes how he thinks about reagent quality. Antibodies are tools scientists depend on, and validation is not optional. Organizers GeneTex GeneTex is a multinational antibody manufacturer founded in San Antonio, Texas in 1997. Since 2020, its recombinant monoclonal antibody facility has produced reagents paired with enhanced validation protocols and a strong emphasis on KO/KD testing. The company's GPCR program is building a comprehensive catalog of recombinant monoclonal antibodies for the human nonsensory and orphan GPCRs.

  • Terry Hébert | Dr. GPCR Ecosystem

    Dr. Terry Hebert on why challenge trials weren't ready, what it takes to hold a GPCR signaling lab together during a pandemic, and the BRET-based beta-1 adrenergic paper that landed in lockdown. << Back to podcast list Strategic Partner(s) Terry Hébert This resilience conversation with Dr. Terry Hebert was recorded in spring 2020, when Montreal was the national epicenter of the COVID-19 pandemic and every non-essential bench in the country was shut. The discussion moves across three scientific registers: the practical mechanics of holding a GPCR signaling lab together remotely; the continuity of receptor pharmacology work already in the pipeline before the shutdown, including a newly accepted BRET-based platform for beta-1 adrenergic receptor signaling built with the Bouvier lab; and a pharmacologist's reasoning about the then-unresolved question of whether human challenge trials were an ethical shortcut to a SARS-CoV-2 vaccine. Dr. Hebert's argument — that challenge trials depend on a reliable therapeutic the field did not yet have — sits at the intersection of drug discovery logic and public health ethics, and illustrates how GPCR scientists reason about pharmacology problems well outside their primary receptor. For Dr. Hebert, the conversation is also about what he had to let go of: the assumption that a lab, once built, runs on its own inertia. About the Guest Dr. Terry Hebert is a professor at McGill University in Montreal, where his lab studies G protein-coupled receptor signaling. His research spans BRET-based assay platforms for characterizing signaling downstream of specific GPCRs, the transcriptional regulation of signaling components as an underappreciated axis of pharmacological modulation, and long-running collaborations on beta-adrenergic receptor biology with the Bouvier lab and others. His work is grounded in careful assay development and a conviction that the signaling space around a receptor is richer than single-pathway readouts suggest. Scientific Themes of the Conversation Lab continuity during institutional shutdown — What it takes to maintain scientific output when the physical lab is closed and every operation has to happen remotely. BRET platforms for GPCR signaling — The role of resonance-energy-transfer-based assays in capturing signaling downstream of specific receptors, with the beta-1 adrenergic receptor as a worked example. Challenge trials and the therapeutic floor — Why the ethics of accelerating vaccine trials depend on having an adequate treatment for the disease under study. Vaccine development at scale — How to read a landscape of 90+ parallel vaccine candidates without confusing breadth of effort for probability of success. Mentorship under isolation — The practical and emotional work of keeping graduate students — especially international students far from their families — connected to a lab that has gone quiet. Pandemic preparedness as a scientific failure — The gap between what infectious disease researchers had been warning about and what institutions were actually ready to do. Key Insights from the Conversation Challenge trials don't work without a reliable drug. Dr. Hebert's core pharmacology argument is that proposing a challenge trial — where volunteers receive placebo or active virus — is ethically unworkable without a therapeutic that can rescue the ones who get sick. His position is that the drug problem has to be solved, or at least bounded, before the vaccine trial design can responsibly change. 90 vaccine candidates is a number about effort, not probability. The conversation pushes against the comfort of large numbers. A field running 90 parallel vaccine trials is a field hedging under uncertainty, not a field with 90 independent chances of success. Dr. Hebert is hopeful but careful about the distinction. BRET platforms carry work forward when the lab can't. The beta-1 adrenergic receptor paper — a BRET-based platform for capturing downstream signaling, built with the Bouvier lab — illustrates how assay-development projects remain productive when benchwork stops. The experimental data was in hand before the shutdown; the intellectual work of writing, reviewing, and revising kept going regardless. A lab is a social infrastructure, not just a physical one. Weekly Monday lab meetings, Friday journal clubs, daily Slack and Zoom contact, a faculty-vs-student trivia night — the lab's continuity came from translating routines, not suspending them. The most fragile link in the system was the isolation of international students away from their families. Reopening is a puzzle about labs, not benches. The hardest logistical problem isn't social distancing within a single lab — it's social distancing between labs sharing a floor, shared equipment, and a public transit system that funnels everyone through the same bottleneck. The warnings were there. Dr. Hebert's reflection on preparedness is quiet but pointed: the scientific community had been warning about this for years. The failure wasn't epistemic — it was institutional. And that failure is what will cost the most, borne hardest by the people least cushioned against it. The next one is coming. The most forward-looking moment in the conversation is also the most sober. This disease, for all its damage, is survivable for most people. The next one might not be. The open question is whether the system will have learned anything by then.

Montreal being the epicenter of the disease in this country — we don't regret that decision now." "I don't think [challenge trials] are a good idea because we don't really have good drugs to deal with the disease when people get sick. If we have a way to control the disease and keep people from getting really sick, I think we can go to challenge trials more rapidly." "Honestly it could be worse, right? This disease, most people survive. When the next one comes, let's hope we learn something from this one." "Those are the people we have to protect, not big corporations who, you know, are probably in a sense part of the cause. Globalization is not something that is without its consequences here."

  • David Gloriam: Orphan Receptors, GPCRDB, and the Data Revolution in GPCR Pharmacology | Dr. GPCR Ecosystem

    Gloriam on orphan GPCR biology, GPCRDB, biased signaling, and how the data analysis bottleneck is reshaping receptor pharmacology and drug discovery. << Back to podcast list Strategic Partner(s) David Gloriam: Orphan Receptors, GPCRDB, and the Data Revolution in GPCR Pharmacology GPCRs represent the largest and most pharmacologically important family of membrane receptors, yet a significant portion remain orphans - proteins whose endogenous ligands and physiological roles are still unknown. This conversation explores the intersection of computational biology, cheminformatics, and structural pharmacology through the work of David Gloriam, whose career spans the identification of 26 novel human GPCRs from genome sequence data to the development of GPCRDB, a community resource used by more than 4,400 researchers monthly. Gloriam's research addresses a central challenge in the field: how to move from a bare protein sequence to a pharmacologically characterized receptor with identified ligands, a determined structure, and a plausible role in physiology. The conversation covers the de-orphanization of GPR139 and GPR55, the unresolved promise of biased agonism as a strategy for safer drug development, and the concept of data-accelerated receptor evolution as a framework for engineering receptor-ligand interactions at the residue level. For Gloriam, this work began with a grandmother's cancer diagnosis and an early determination to develop drugs - a goal that led him through the human genome and into a decades-long pursuit of receptors whose functions remain to be written. ABOUT THE GUEST David Gloriam is a professor at the University of Copenhagen's Department of Drug Design and Pharmacology, where he leads a multidisciplinary research group working across data science, computational drug design, pharmacology, and structural biology. His primary research focus is orphan GPCR biology, with particular emphasis on identifying endogenous ligands and physiological roles for receptors discovered during the human genome sequencing era. He maintains and develops GPCRDB, a continuously updated database and tool platform that integrates structural, functional, and ligand data for the entire GPCR superfamily. His group contributed to the de-orphanization of GPR139 and GPR55, including the identification of sub-nanomolar peptide ligand candidates, and has published widely on computational approaches to GPCR drug discovery and receptor classification. SCIENTIFIC THEMES OF THE CONVERSATION Orphan GPCR biology - the challenge of connecting a protein sequence to a physiological function GPCRDB as community infrastructure for integrating and accelerating GPCR research The interdisciplinary de-orphanization pipeline: from bioinformatics to pharmacology to structure The data interpretation bottleneck - how the field's rate-limiting step has fundamentally shifted Biased agonism: from theoretical framework to the challenge of pathway-specific drug design Data-accelerated receptor evolution: engineering GPCR function at the single residue level KEY INSIGHTS FROM THE CONVERSATION The Human Genome as a Discovery Platform When Gloriam joined a bioinformatics group during his master's studies, the first human genome sequence had just become available. Working within that resource, his group identified 26 previously unknown GPCRs in the span of a few years - a pace of discovery that would have been impossible through classical biochemical approaches. The experience established his conviction that computational analysis could function as a genuine primary discovery tool, not merely as support for bench science. De-Orphanization Is a Full-Discipline Effort The process of characterizing an orphan receptor from protein sequence to identified ligand to determined structure cannot be completed within a single lab or a single methodology. Gloriam described the journey of GPR139 as spanning sequence-based phylogeny, database mining for tissue expression, virtual screening, pharmacological assay development, machine learning-guided ligand identification, and finally structural collaboration with external groups. The full arc took more than a decade and required sustained coordination across disciplines that rarely share a lab bench. Taking Over GPCRDB Without a Safety Net When the original GPCRDB team approached retirement, Gloriam chose to carry the resource forward despite holding no tenure and working under a two-year contract. He described it as one of the major single decisions of his career - a bet that the community would respond and the opportunity would justify the risk. The response exceeded his expectations: within years, researchers he had never met were greeting him at conferences by name because of the database. The Bottleneck Has Flipped For most of the history of pharmacological research, generating reliable data was the rate-limiting step. Gloriam argued that this has fundamentally changed: the volume and diversity of available data now far outpaces the field's capacity to analyze and interpret it. This shift places data scientists and computational biologists in a newly central role - not as support for experimentalists, but as the primary constraint to overcome in advancing receptor biology. Biased Agonism Still Needs Its Proof of Concept A drug designed around biased agonism principles received regulatory approval, but its actual functional selectivity has since been questioned - with some researchers arguing it may be a partial agonist rather than a genuinely biased compound. Gloriam identified this ambiguity as symptomatic of a deeper challenge: the field has not yet fully characterized which signaling pathways produce therapeutic benefit and which produce side effects across the GPCR targets most relevant to disease. Until that pathway-level map is built, designing genuinely biased drugs remains a hypothesis in search of its first clean demonstration. Leadership Is a Learnable Skill - If You Seek the Training Gloriam took formal research leadership training before his group was large enough to require it - acting on advice from mentors who recognized that funding panels wanted evidence of leadership readiness alongside scientific merit. He described coaching sessions, national leadership courses, and the deliberate selection of mentors who had recently navigated the specific challenges he was facing. The result was a structured group management model built around four specialized subgroups, each with a senior researcher as daily supervisor - a design that reduced bottlenecks and allowed the science to scale beyond what one group leader could hold. Open Science as the Next Infrastructure Problem Gloriam articulated a vision for GPCRDB as more than a data repository - a shared scientific workspace where researchers could surface big unsolved problems, correspond across institutions, design experiments collectively, and deposit results in a structured format accessible to the entire community. He described the complete characterization of biased signaling pathways across all GPCRs as one such challenge: too large for any single group, and structurally dependent on coordinated community effort that currently has no home.

"The day I stop learning, I might as well die. For me, the actual development - that's the thing. And that's the fun part." "I walked in there and I did the best performance ever. And I walked out and I felt - I think I did it. I did it, yes." "When I come into work and I have a group member that does something better than I do - that's actually what makes me the most proud." About this episode David Gloriam is a Professor in Computational Receptor Biology at the University of Copenhagen where he leads a research cluster for GPCR function and drug discovery and a Pharmaceutical Data Science unit. His group runs the GPCRdb database where ~4,000 researchers each month retrieve reference data and access online tools for analysis, visualization, and experiment design. David obtained his Ph.D. from Uppsala University in Sweden where he worked on the bioinformatic identification of 24 novel human G protein-coupled receptors. He later identified physiological hormones of such under characterized ‘orphan’ receptors and functional probes for a range of receptors. He completed two postdocs in the UK at the EMBL-European Bioinformatics Institute and GlaxoSmithKline . In 2018 he joined the University of Copenhagen, where he has received an ERC Starting Grant, Lundbeck Foundation Fellowship, and Novo Nordisk Foundation Ascending Investigator awards. Dr. Gloriam is a corresponding member of the Nomenclature Committee of the International Union of Pharmacology (IUPHAR).

  • Scaling GLP 1 Receptor Tools Through Academia Industry Collaboration | Dr. GPCR Ecosystem

    How academia and biotech collaborate to scale GPCR tools—covering fluorescence assays, GPCR internalization, and real-world distribution. Episode 3 of 3. << Back to podcast list Strategic Partner(s) Scaling GLP 1 Receptor Tools Through Academia Industry Collaboration How do GPCR tools move from individual academic labs into broad use across the research community? In this episode of the Dr. GPCR Podcast , leaders from academia and biotech unpack what effective collaboration really looks like when developing, validating, and distributing GPCR research tools. Joining the conversation are Maria Majellaro (CSO and co-founder of Celtarys Research), Johannes Broichhagen, and David Hodson. Together, we discuss how gpcr drug discovery advances when chemists, biologists, and industry partners align around rigor, trust, and accessibility. The episode explores gpcr internalization , fluorescence-based probe design, and how functional assay development benefits from scalable distribution rather than ad-hoc sharing. Listeners will walk away with a clearer view of how academic innovation translates into tools for high-throughput screening , and why availability can be as impactful as discovery itself. Why This Matters How GPCR tools lose impact when distribution and access aren’t planned from the start Why fluorescence-based assays outperform antibodies for studying receptor localization and trafficking What changes when academia and biotech share priorities instead of working in parallel When industry partnerships become essential for reproducibility and scale The moment when availability—not innovation—becomes the bottleneck in GPCR research Who Should Listen This episode is for scientists and leaders who are: Navigating the transition from academic tool development to real-world adoption Balancing innovation with validation in GPCR assay design Building reagents that must work in complex tissues, not just simplified models Exploring academia–industry collaboration but want to understand how it works in practice This conversation is part three of a three episode series produced in collaboration with our partners at Celtarys Research . 🎧 Listen to Part 1 with Dr. Hudson 🎧 Catch up on Part 2 with Dr. Broichhagen About the Guests Maria Majellaro, PhD Dr. Maria Majellaro is the Chief Scientific Officer and co-founder of Celtarys Research , a biotech spin-off from the University of Santiago de Compostela focused on advanced fluorescent ligands and GPCR research tools.

  • Jacob Lee and Jin Cho: Rebuilding the Software Layer Under Modern Research | Dr. GPCR Ecosystem

    Jacob Lee and Jin Cho, co-founders of GeneMode, on the ten billion dollars American labs waste every year — and why rebuilding research software from scratch is the most direct path to faster cures. << Back to podcast list Strategic Partner(s) Jacob Lee and Jin Cho: Rebuilding the Software Layer Under Modern Research Most scientific research still runs on infrastructure built for a different century. Spreadsheets lock when two people open them. Freezer inventories live in a senior postdoc's head. An estimated ten billion dollars is spent every year in the United States rebuying reagents already sitting on a shelf nobody could find. In this conversation, Jacob Lee and Jin Cho — co-founders of GeneMode — describe what they saw when they looked at that infrastructure as outsiders and as scientists at once. Lee is a bioengineer whose first year of graduate school was defined by scheduling thirty-minute appointments on a senior postdoc's calendar just to access the lab's inventory software, and that experience is what turned frustration into a company. Cho came from engineering software for military drones at General Atomics, and was stunned when he saw what his friend's lab was paying for a tool that looked straight out of Windows XP. They talk about the slow architecture of drug discovery, the compounding cost of irreproducibility, and why rebuilding the tools scientists use every day is, for them, the most direct path to getting cures to patients faster. About the Guests Jacob Lee is the CEO and co-founder of GeneMode. He trained as a bioengineer and worked as a research scientist in stem cell and cancer labs before founding the company. His frustrations as a first-year graduate student navigating inaccessible lab software became the seed for GeneMode. He leads the company's product vision, focused on inventory, experiment management, and research reproducibility. Jin Cho is the CTO and co-founder of GeneMode. Trained in electrical and computer engineering, he began his career at General Atomics building software for military drones before reuniting with his high-school friend Lee to rebuild research tools from the ground up. At GeneMode he leads the engineering team and the platform's weekly release cycle. Scientific Themes of the Conversation The cost of irreproducibility — waste, delay, and the compounding friction of bad tools Access asymmetry in research — who gets to use the lab's software, and who waits Research software as infrastructure — why tools built for scientists behave differently than tools adapted to them The drug discovery timeline — preclinical, clinical, and regulatory phases, and where software actually matters Collaboration in shared labs — real-time editing, shared freezers, and the Excel-lock problem Lab automation and the hidden operating cost of being a scientist Key Insights from the Conversation Ten billion dollars vanishes every year into duplicate reagent orders. Lee describes an estimate that American labs spend roughly ten billion dollars annually on reagents they already own but can't locate. The cost isn't just money — it's the erosion of reproducibility that follows from not knowing what's in the freezer. Access to the lab's tools is often rationed by seniority. In Lee's first graduate lab, only the principal investigator and a senior postdoc had logins for the expensive inventory software. As a student, he scheduled thirty-minute appointments on a postdoc's calendar to learn how to use a tool the lab had already paid thousands of dollars for. Excel is the default research tool because no one built a better one for scientists. The co-founders argue that most lab software wasn't built for scientists — it was built for general business use and retrofitted. That explains the locked files, the manual re-entry, the outdated look, and the poor fit with how research actually moves. Lab infrastructure is the hidden variable in drug discovery timelines. COVID-era conversations about why vaccines take eighteen months tend to focus on the clinical and regulatory phases. Lee reframes the question toward the preclinical phase, where data management and reproducibility quietly compound every delay downstream. Private and shared workspaces both matter, even in collaborative labs. Cho and Lee describe designing for the reality of shared benchwork: most labs want everything visible to everyone, but individual scientists still need space for protocols-in-progress or personal collections they're not ready to publish internally. Fast release cycles are a signal of infrastructure maturity. Cho describes shipping updates weekly, prioritizing customer-reported bugs and feature requests with a design-to-test-to-ship loop that most scientific software vendors don't attempt. That cadence is itself a philosophical statement about who the tool serves. A ninth-grade English class is an unlikely origin for scientific infrastructure. The GeneMode story starts with two teenagers in the same high-school classroom, different majors, different career paths, and a late-night message asking whether lab software could be hacked together in a weekend. The answer turned out to be no — but the question turned into a company.

And what surprised me even more was his lab was paying thousands of dollars for this legacy-looking software. I was mind-blown." — Jin Cho "In a lab of ten people, only the principal investigator and a very senior postdoc had access to the software. And as a student, I had to actually schedule times on my postdoc's calendar in thirty-minute segments just to learn how to use that tool." — Jacob Lee "The end goal is really much bigger than helping scientists manage their research projects or inventory. Our mission is to make that research repeatable and reproducible so that we can get those cures faster." — Jacob Lee About this episode In this special episode of the Dr.GPCR podcast , I sat down with the co-founders of Genemod . Jacob Lee and Jin Choe met in ninth grade in English class and have been friends since. Although both went to the same college, Jacob and Jin choose different career paths. One day as they were catching up, Jacob shared his struggles of managing samples and an incredible amount of data and projects in the lab with Jin. Our of this need Genemod was born. Today, Genemod has built a freezer management tool and a project management tool where scientists can manage their reagents, samples, and projects on one intuitive platform. The team is planning on building even more tools that will make Genemod the go-to platform for all research scientists to make research more efficient.

  • Annette Gilchrist: Native Cell Systems, Biased Agonism, and the Pharmacogenomics Gap | Dr. GPCR Ecosystem

    Annette Gilchrist on why native cell systems change GPCR screening, constitutive beta-arrestin activity at FFA2, and the pharmacogenomics gap in drug discovery. << Back to podcast list Strategic Partner(s) Annette Gilchrist: Native Cell Systems, Biased Agonism, and the Pharmacogenomics Gap Biased agonism promised a cleaner path to better drugs - compounds that activate the beneficial arm of a receptor while leaving the harmful one alone. In practice, the picture is far more complicated. Whether a 20% reduction in beta-arrestin coupling matters therapeutically depends on the cell type, the complement of intracellular effectors present, and the receptor's own baseline activity in that tissue. These are questions you cannot answer in a HEK cell overexpressing a receptor it was never meant to see. Annette Gilchrist has built her research program around that premise. Working on chemokine receptor CCR1 in multiple myeloma, free fatty acid receptor FFA2 in type 2 diabetes, and muscarinic receptors, her lab screens in disease-relevant cell lines and looks early for signaling bias - not as a theoretical exercise, but as a practical filter on what a compound might actually do in a patient. That discipline led to a finding her field had not documented before: constitutive beta-arrestin activity at a wild-type FFA2 receptor, suppressible by an inverse agonist that then redirects signaling toward GQ coupling. For Gilchrist, the result was not a surprise so much as a confirmation - if you look in the right system, receptors show you things overexpression models never could. ABOUT THE GUEST Annette Gilchrist is Associate Professor of Pharmaceutical Sciences at Midwestern University, where her research focuses on GPCR signaling in disease-relevant contexts. Her lab studies chemokine receptor CCR1 in multiple myeloma and cancer-to-bone metastasis, free fatty acid receptor FFA2 in type 2 diabetes, and muscarinic M2 and M3 receptors, consistently prioritizing native and disease-proximal cell systems for screening. Before returning to academia, she co-founded two GPCR-focused biotechs with Heidi Hamm - CUE Biotech and Caden Biosciences - developing G-protein C-terminal mini-gene peptide tools that became widely adopted across the field. She also brings early industry experience from Pfizer, where her first sustained encounter with pharmacology as a discipline shaped how she has thought about the relationship between target validation and drug development ever since. SCIENTIFIC THEMES OF THE CONVERSATION The native cell argument - why overexpression models produce systematically misleading screening data and what disease-relevant cell lines reveal instead The practical limits of biased agonism - cell-type context, effector availability, and why the G-protein vs. beta-arrestin framing rarely holds at the clinical level Constitutive beta-arrestin activity and inverse agonism - a first-in-kind finding at wild-type FFA2 and its implications for biased ligand campaign design GPCR pharmacogenomics - natural receptor variation, interpatient drug response differences, and a largely unexplored opportunity in existing drug pipelines Antibody therapeutics for GPCRs - the pipeline case, the approval rate argument, and why orphan receptor targeting may not require knowing the endogenous ligand Receptor dimerization - BRET biosensors, what we still do not know about physiological relevance, and why the tools are finally beginning to close the gap KEY INSIGHTS FROM THE CONVERSATION The cell you screen in determines the biology you can find Running a GPCR screen in a HEK cell overexpression model removes the intracellular proteins a receptor actually encounters in disease tissue - effectors like Go or Gz that are critical in neuronal signaling, for example, and simply absent in standard lines. Gilchrist has argued for disease-relevant cell systems for over 15 years, and her lab's discovery of constitutive beta-arrestin activity at FFA2 is a direct product of that discipline - a result that would have been invisible in a standard overexpression model. Biased agonism is context-dependent, not receptor-intrinsic The field has treated biased agonism largely as a property of a compound and a receptor. Gilchrist's argument is that it is also a property of the cell. The same compound may produce a functionally meaningful shift in one cell type and a negligible one in another, depending on the G-protein isoforms present, the receptor conformation in that membrane environment, and what other proteins are competing for the same intracellular space. How much bias is enough is not a pharmacological question with a single answer. An inverse agonist where none had been reported - constitutive beta-arrestin coupling at FFA2 Gilchrist's lab entered the FFA2 project looking for GQ-biased agonists to drive insulin release. What they found instead was that FFA2 appears to be constitutively coupled to beta-arrestin in the relevant cell system - and that an inverse agonist against that constitutive activity effectively redirects the receptor toward GQ coupling. It was a result that had been documented in a mutant vasopressin receptor but never in a normal wild-type receptor. The aha moment was not the result itself but recognizing what it meant for how you could design the campaign. Pharmacogenomic variation in GPCRs may already be shaping clinical drug response - unacknowledged A paper by Hauser mapped pharmacogenomic variation across the GPCR-ome and showed, among other findings, that many of the GPCRs carrying the highest mutation loads are hormone receptors - FSH, LH, and others implicated in fertility. Patients taking drugs that target GPCRs with natural population-level variants are almost certainly responding differently based on their receptor genetics. Almost no company with an approved GPCR-targeting drug has gone back to look at what common receptor variants do to their compound. Gilchrist believes they should. The mini-gene origin: reading one paper, seeing the missing experiment While a postdoc in Heidi Hamm's lab, Gilchrist read a paper describing how BARK C-terminal peptides had been inserted into a plasmid as tools. The question that followed was immediate: why hadn't anyone done the same with G-protein C-termini? The peptides she developed - 11 amino acids rather than 55, which created their own detection challenges - became widely used across the field for measuring receptor-G-protein interactions and screening for allosteric modulators. The insight was not a long deliberation. It was a single reading of someone else's work and a recognition that an obvious experiment had not yet been done. Antibody therapeutics for GPCRs: the pipeline argument Biologics have a substantially higher success rate than small molecules moving through the drug development pipeline. GPCRs are well-validated targets with known physiological relevance. The combination of those two facts, Gilchrist argues, makes antibody-based GPCR therapeutics an underexplored area - particularly for orphan GPCRs, where compounds are already being developed against receptors whose endogenous ligands remain unknown. The precedent of drugging a receptor without knowing what activates it naturally, and getting therapeutic results, suggests the field does not always need the full biology before it can act on the pharmacology. The first screen: looking for antagonists, finding agonists instead The principle that Gilchrist now teaches - follow the unexpected result, ask why it happened, do not repeat it away - came from her own first encounter with exactly that situation. Running a small-molecule screen in Heidi Hamm's lab, looking for compounds that would block G-protein binding, she found agonists: compounds that made the G-protein bind better, some of which trapped the receptor in a state where it could not signal further. It was not the experiment she had designed. The years of research that followed came directly from not dismissing it.

You do it because you can't imagine your life doing anything else. I do science because I love science. I love asking a question - I get to find an answer that nobody else knows, potentially." "I had no idea that I would find agonists, biased agonists, as well as antagonists the first time I did my screen. When you have a finding that is completely unexpected, you follow it. You ask the question: why did that happen? Instead of just trying it again." "How much is enough in terms of turning it down? Is a 20% reduction of beta-arrestin signaling enough? I think it is probably cell-dependent. So much of the interaction depends on the conformation of the receptor in that particular cell." "As much as it's been wonderful to get crystal structures and use molecular dynamics, there are still so many questions that we have no idea what the answer is. I guess that's one of the best things about GPCRs - there's always something to look at."

She is a National Heart Foundation of Australia Future Leader Fellow and runs a laboratory of 7 Ph.D. and Honours students at UNSW Sydney, where she has recently been promoted to Associate Professor. Most recently, Dr. Smith’s team has made advances in the understanding of how an orphan GPCR exerts its effects both in vitro (cell culture and ex vivo models) and in vivo (measures of physiological and pathological cardiometabolic function in unconscious and conscious mice). Together with Irina Kufareva , UCSD, her team developed a novel approach to identifying ligands for orphan GPCRs by developing a powerful new computational tool for identifying ‘surrogate’ ligands (borrowed from other receptors) for orphan GPCRs, named GPCR-CoINPocket. Her career goal is to leverage this expertise to establish a research program that takes orphan GPCRs from ‘locked’, inaccessible receptors to well-characterized and understood ‘unlocked’ therapeutic targets with high-affinity ligands.

Then I pursued my education in the lab of Dr. Maria Waldhoer at the Medical University of Graz, Austria, and received my Ph.D. in Molecular Medicine in 2010 after studying the orphan atypical cannabinoid receptor, GPR55 and its crosstalk with CB1R and CB2R in endothelial cells and neutrophils. I followed my interest in allergy and GPCRs by joining the lab of Dr. Kirk Druey at NIAID/NIH, where I characterized the role of RGS4 and RGS5 in airway hyperresponsiveness and lung fibrosis in acute and chronic mouse models of allergic asthma. I was fascinated by the multitude of processes that are regulated/dysregulated by GPCRs and RGS proteins in the lungs of patients with asthma. At the height of curiosity, a seemingly naïve idea at the dinner table led to a side project by which I characterized the impact of a fungal allergenic source on the function of airway smooth muscle cells. A fungal serine protease allergen with GPCR-modulating features was discovered as a new biomarker and target in patients with severe asthma. In 2015 I joined the University of Maryland School of Medicine as an Assistant Professor. I studied the function of RGS5, calcium-sensing receptor, and an orphan adhesion GPCR, GPR64/ADGRG2 in parathyroid glands of patients with hyperparathyroidism and their impact on body calcium homeostasis and bone resorption in relevant transgenic mice.

    Chemical biologist Johannes Broichhagen reveals how fluorescent probes transform GPCR imaging, internalization studies, and assay development in live cells and tissues. << Back to podcast list Strategic Partner(s) Chemical Probes for GPCR Imaging and Internalization with Dr. Johannes Broichhagen In this episode of The Dr. GPCR Podcast, chemical biologist Dr. Johannes Broichhagen shares how his lab builds next-generation fluorescent probes to visualize GPCRs with precision. From the early days of ion channel chemistry to pioneering peptide–fluorophore conjugates for the GLP-1 receptor, JB breaks down the strategic decisions that shaped these tools—and why reliable chemical probes are transforming GPCR drug discovery . He explains what chemical design can solve that antibodies can’t, how to validate functional assay systems, and why fluorescence-based assays paired with careful synthetic planning open doors for both high-resolution imaging and high-throughput screening . You will walk away with a deeper understanding of GPCR internalization, probe specificity, and the cross-disciplinary habits that make collaborations actually work. Why this matters How a chemist with zero biology training became a leader in GPCR probe design. Why peptide-based fluorescent ligands succeeded where antibodies repeatedly failed. What actually happened the moment JB and collaborators imaged an entire pancreatic islet in one shot. How parallel synthesis and side-by-side functional assays accelerate probe optimization and reduce false leads. Why targeting the pharmacologically relevant surface-exposed receptor pool changes the way scientists interpret GPCR trafficking. The moment when super-resolution imaging revealed nanoscale receptor domains that conventional tools completely missed.

  • Robert J. Lefkowitz: Beta-Adrenergic Receptors, the GPCR Family, and Fifty Years of Discovery | Dr. GPCR Ecosystem

    Nobel laureate Robert Lefkowitz traces the accidental origins of his receptor research — from a Vietnam War draft to the cloning of the beta-2 adrenergic receptor — and reflects on what it takes to choose the right scientific problem and survive 50 years of failure. << Back to podcast list Strategic Partner(s) Robert J. Lefkowitz: Beta-Adrenergic Receptors, the GPCR Family, and Fifty Years of Discovery The existence of hormone receptors as discrete molecular entities was, for much of the 20th century, an open question. When Robert Lefkowitz arrived at the NIH in 1968 — not by scientific calling but by a Vietnam War draft assignment — the prevailing view held that receptors were at best allosteric binding sites on adenylyl cyclase. There was no proof they were physically distinct molecules. Over the following decades, Lefkowitz and his collaborators transformed this conceptual uncertainty into molecular fact. Using radioligand binding assays developed for the beta-adrenergic receptor system, his lab purified, then cloned the beta-2 adrenergic receptor — a 1986 Nature paper that unexpectedly revealed structural homology with rhodopsin and established the GPCR superfamily. The same system yielded the discovery of beta-adrenergic receptor kinase (now GRK2) and the beta-arrestins — three of the four central molecular components of GPCR signaling. This conversation traces the scientific logic and human contingency behind those discoveries: how to choose a problem at the edge of tractability, what failure looks like at 98%, and why Lefkowitz considers sharing a Nobel Prize with his own trainee the most personally meaningful moment of a fifty-year career. ABOUT THE GUEST Dr. Robert J. Lefkowitz is James B. Duke Distinguished Professor of Medicine and Biochemistry at Duke University, where he has led his laboratory since 1973. His research established the beta-2 adrenergic receptor as the primary model system for understanding GPCR structure, regulation, and signaling — work that produced the first purification, cloning, and sequencing of a GPCR and led directly to the recognition of the receptor superfamily. His lab developed the GRK (G protein-coupled receptor kinase) family and discovered the beta-arrestins, proteins now understood as central mediators of receptor desensitization and G protein-independent signaling. In 2012, Dr. Lefkowitz was awarded the Nobel Prize in Chemistry, shared with Brian Kobilka, for studies of G protein-coupled receptors. SCIENTIFIC THEMES OF THE CONVERSATION The receptor hypothesis before proof — The conceptual and experimental gap between classical pharmacology's functional receptor concept and the physical demonstration that receptors are discrete molecular entities. Beta-adrenergic receptors as a model system — Why the adrenergic system, with its rich pharmacological toolkit and cardiovascular relevance, made it the right platform for receptor biochemistry. Radioligand binding and the first demonstration of GPCR structure — The methodological progression from iodinated hormone binding to radioligand development to purification, and what each step required. The cloning race and the serendipity of the intronless gene — Competing against Genentech's molecular biology infrastructure, screening a genomic library against expert advice, and the unexpected absence of introns that closed the race. High output vs. low output failure: choosing the right scientific problem — The framework Lefkowitz articulates for navigating between trivial, solvable problems and important, intractable ones — and how that judgment is transmitted through mentorship. Scientific lineages and the transmission of scientific taste — How the values that make a scientist effective — problem selection, tolerance for failure, the instinct to pursue surprising results — are absorbed through proximity rather than instruction. KEY INSIGHTS FROM THE CONVERSATION 1. Receptors were an unproven concept when Lefkowitz chose to study them When Dr. Lefkowitz committed to receptor research in the early 1970s, prominent pharmacologists, including Raymond Ahlquist — who had introduced the alpha/beta receptor classification — publicly disputed the physical existence of receptors. At a 1973 symposium, Ahlquist responded to Lefkowitz's research plans by stating in print that hormone receptors were "a figment of Dr. Lefkowitz's imagination." Choosing that problem required betting a career on a concept that the field's own architects considered speculative. 2. The strategic logic behind choosing beta-adrenergic receptors The selection of the beta-adrenergic system was not intuitive — it was architectural. Dr. Lefkowitz identified three requirements: a receptor linked to adenylyl cyclase (providing a proximate, measurable downstream signal), cardiovascular relevance (matching his clinical training), and a pharmacological toolkit deep enough to support radioligand synthesis, analog competition studies, and affinity chromatography. The adrenergic system was the only one that satisfied all three. He reflects, fifty years later, that it was probably the smartest research decision he ever made. 3. The cloning race was won by doing the thing experts said was stupid Competing against Genentech — then the world leader in recombinant DNA technology — Dr. Lefkowitz's lab was getting nowhere screening plasmid libraries. When Brian Kobilka proposed screening a genomic library, Merck's molecular biology collaborators called it a stupid idea: introns would make a genomic clone useless. Lefkowitz and Kobilka screened it anyway. Not only did they pull clean clones immediately — they found that the beta-2 adrenergic receptor gene contains no introns, only the third mammalian gene to that point discovered to be intronless. The race ended. 4. The moment the GPCR family became visible As sequencing of the cloned beta-2 AR proceeded in 1985–86, Lefkowitz expected the receptor to look like nothing else — the first member of an unknown family. The discovery that it was structurally homologous to rhodopsin was a complete surprise. Functional analogies between the two systems had been recognized — both were G protein-coupled — but no one had predicted structural relatedness. The realization that the sequence matched a known protein was, as Dr. Lefkowitz describes it, "a total shocker." It was the moment they understood that all GPCRs would share this architecture. 5. The 98% rule and what it means to take on important problems Dr. Lefkowitz describes a senior scientist at the NIH who told him early in his career that the difference between an average scientist and a world-class one is the failure rate: 1% success versus 2%. He has carried that framing for fifty years. When a collaborator once told him that nearly everything he was working on was succeeding, Lefkowitz told him that was a problem — if 50% of your experiments work, you are not working on hard enough problems. He aims for 10–20%. 6. Mentorship is absorbed, not taught Dr. Lefkowitz argues that the most critical skill in science — choosing a problem that is important but tractable — cannot be explained by a mentor. It is acquired by watching: how a scientist moves between problems, when they persist, when they drop something, what surprises them enough to redirect attention. This is why scientific lineages exist. The values that produce important work are transmitted the way values always are — through proximity, observation, and time. 7. Sharing the Nobel with a trainee he never interviewed When Dr. Lefkowitz learned at 5 AM on October 10, 2012, that he had won the Nobel Prize in Chemistry, his first reaction was not elation — it was relief. The question he had been asked for years — when are you going to win the Nobel Prize? — would never need to be asked again. His second reaction, on learning he would share the prize with Brian Kobilka, was more personal. Kobilka had applied to Duke without ever meeting him, had joined the lab without an interview, and had been the scientist at the bench for the cloning work that anchored the prize. "That brought a tear to my eye." EPISODE TIMELINE Timestamps are AI-generated from the transcript and are approximate.

It was that serendipitous event that basically changed the entire course of my life and career." "He got up and said, it's all very nice. But he says, this is a figment of Dr. Lefkowitz's imagination. There's no such thing as a receptor. And I remember thinking to myself as a young buck at the time: I'm going to show this guy. It took a hell of a long time." "If half of everything I'm trying to do is working, I'm not taking on very challenging stuff. I really stick around 10 or 20%. What you're seeing is a trivial fraction. Most of what we do fails. But that's science." "It was more a sense of relief, I think, and quiet satisfaction. The monkey's off my back. I realized in that moment that I would never again have to answer the question: Bob, when are you going to win the Nobel Prize?" About this episode It was December 14th, 2020, 1:50 pm, when I turned on my laptop and signed into Zoom for my chat with Bob. Bob, who, you might ask? Well, it’s the one and only Robert J. Lefkowitz, M.D., 2012 Nobel Prize in Chemistry, which he shared with Dr. Brian Kobilka . Bob doesn’t really need an introduction since his reputation precedes him. Before we pressed record, I asked if I could call him Bob, and he answered that only his mom used to call him Robert, especially when she was upset with him. I then pressed record, and we chatted for almost 2h about Bob’s career, discoveries, difficulties (yes, he’s had some too), Nobel week, and his memoir that he just published in collaboration with Dr. Randy Hall. Bob is James B. Duke Professor of Medicine and Professor of Biochemistry, Chemistry, and Pathology at the Duke University Medical Center. He began his career in the late 1960s and has been an Investigator of the Howard Hughes Medical Institute since 1976.

  • Model. Predict. Discover. with Dr. Jens Carlsson | Dr. GPCR Ecosystem

    Can models predict drug outcomes? Jens Carlsson shares how GPCR modeling is moving from explanation to real prediction in drug discovery. << Back to podcast list Strategic Partner(s) Model. Predict. Discover. with Dr. Jens Carlsson What if models didn’t just explain the past — but could truly predict what comes next? In this episode, Dr. Jens Carlsson reveals how computational modeling is evolving from explanation to real prediction—and how that shift accelerates real-world discovery. Dr. Jens Carlsson, Professor of Computational Biochemistry at Uppsala University, joins Dr. Yamina Berchiche to share his unconventional journey from aspiring engineer to GPCR modeler. With a deep focus on structure-based drug design, Jens discusses how his lab bridges simulation and experiment—and why understanding the limits of prediction is just as critical as the predictions themselves. From virtual screening of billions of molecules to leveraging AlphaFold for structure prediction, Jens shares the cutting-edge tools his lab uses—and the collaborative mindset required to turn models into testable hypotheses. Along the way, he reflects on key career moments, the role of mentorship, and how curiosity continues to drive his work across both academic and industry settings. Why This Matters Computational models are moving beyond interpretation into real-world prediction of ligand-receptor interactions. Bridging computation, chemistry, and pharmacology is key to speeding up drug discovery. AI and machine learning are opening new doors—but only if scientists know their tools’ limits. What You’ll Learn Why Jens Carlsson believes modeling should predict , not just explain How his team uses structure-based modeling to identify novel GPCR ligands The value of failure—and how it shaped his path as a scientist Why collaborations between modelers and experimentalists are more vital than ever How AlphaFold is shaking up structural biology—and where it still falls short Advice for junior scientists: what really matters when building a research career Who Should Listen GPCR scientists and pharmacologists Computational chemists and structural biologists Early-career researchers exploring drug discovery Biotech leaders and R&D strategists Anyone interested in predictive modeling, AI in biology, or structure-function relationships About Jens Carlsson Jens Carlsson is a Professor of Computational Biochemistry at Uppsala University, where his research group uses structure-based modeling to investigate GPCRs.

  • Aaron Sato: Synthetic Antibody Libraries for the Hardest GPCR Targets | Dr. GPCR Ecosystem

    Dr. Aaron Sato on building the synthetic antibody library that finally makes GPCRs tractable — and the greenfield strategy that led him there. << Back to podcast list Strategic Partner(s) Aaron Sato: Synthetic Antibody Libraries for the Hardest GPCR Targets GPCRs account for a substantial fraction of validated drug targets, yet most are drugged by small molecules — antibodies against GPCRs remain notoriously difficult to discover. This conversation explores how synthetic antibody phage display libraries, built on silicon-based DNA synthesis, are rewriting that constraint. Dr. Aaron Sato, CSO of Twist Biopharma, describes the motif-directed library his team developed by collecting known GPCR-binding sequences from protein, peptide, and antibody ligands and seeding them into the heavy chain CDR3 of a fully human synthetic library. The discussion covers why degenerate oligos had been the bottleneck for library quality, how a "library of libraries" strategy sidesteps the ten-billion-variant ceiling that caps any single phage library, and why the team can now move from a GPCR target to a bivalent IgG ready for functional assays in eight to ten weeks. For Aaron, this work is personal: he has built his career hunting greenfield targets where others had failed — and GPCRs were the greenfield he had been waiting for. About the Guest Dr. Aaron Sato is the Chief Scientific Officer and VP of Protein Engineering at Twist Biopharma, the biologics division of Twist Bioscience. He earned his PhD at MIT in the laboratory of Lawrence Stern, where he studied structure-function relationships of MHC class II proteins by X-ray crystallography. His career has traced the evolution of antibody engineering, with leadership roles at DIAX, Oncomed, Sutro Biopharma, and Lake Pharma before joining Twist. His current focus is building synthetic phage display libraries that drug targets the field has long treated as intractable — GPCRs chief among them. Scientific Themes of the Conversation Silicon-based DNA synthesis and the end of degenerate oligos in library design Motif-directed library design — encoding ligand-binding sequences into CDR3 architecture The library of libraries as an answer to the diversity ceiling of single phage libraries Greenfield target selection as a drug discovery strategy Family-level cross-reactivity as an advantage, not an obstacle, in GPCR antibody discovery Timelines, automation, and the industrialization of antibody workflows Key Insights from the Conversation Silicon DNA synthesis removes the degenerate oligo bottleneck. Traditional synthetic libraries rely on degenerate or trinucleotide mixtures to encode CDR diversity, which limits control over which variants actually appear. Twist's silicon platform produces pools of discrete, designed sequences — a shift in how synthetic libraries are composed. The motif-directed library encodes prior biological knowledge directly into CDR3. By curating protein, peptide, and antibody motifs known to bind GPCRs and inserting them at the top of the heavy chain CDR3, the library enters each panning campaign already biased toward the target class. The design decision is the library's main differentiator. A motif-directed library reaches targets its motifs weren't designed for. The same library has produced antibodies against orphan GPCRs and receptors without peptide ligands, because the surrounding CDR diversity provides enough variation to find binders outside the seeded motif content. Phage display's ~10¹⁰ variant ceiling can be broken by stacking libraries. Any single phage library is capped near ten billion variants. Running multiple libraries in parallel moves the effective diversity toward 10¹² — the idea Aaron calls his library of libraries. Eight to ten weeks from a GPCR target to a functional IgG is the platform's working tempo, not a best case. By skipping fragment-based screening and going directly to full bivalent IgG, the team hands functional biology teams a molecule that is ready for flow cytometry and receptor assays almost immediately. Aaron's strategy is deliberately greenfield. He looks for target classes where existing platforms have already failed — not because the biology is easier, but because new technology is rewarded most where the incumbents have stalled. GPCR family architecture is a discovery advantage. Receptors within a family share sequence and surface topography, so an antibody recovered against one member is often a legitimate starting point for discovery across the family.

"I often love to look for my greenfield areas, where there's not a lot of competition because there's just really no technology that enables you to drug specific targets." "In phage display, you're oftentimes kind of capped out around 10 billion different antibodies per library. One way around that limited diversity is to actually have multiple libraries." "GPCR antibodies are just so intractable oftentimes." About this episode In this episode of the Dr. GPCR Podcast , I spoke to Dr. Aaron Sato from Twist Biopharma , a vertical within Twist Bioscience . Aaron is currently the Chief Scientific Officer and VP of Protein Engineering.

  • Masha Niv: Bitter Taste Receptors and the Drug Discovery Blind Spot | Dr. GPCR Ecosystem

    Masha Niv on bitter taste GPCRs, the drug bitterness blind spot, and what heavy water reveals about the sweet taste receptor. << Back to podcast list Strategic Partner(s) Masha Niv: Bitter Taste Receptors and the Drug Discovery Blind Spot Taste receptors are among the most overlooked GPCRs in pharmacology - and Masha Niv has spent her career building the tools to change that. This conversation explores the biology, diversity, and unexpected reach of human taste GPCRs, beginning with the 25-subtype family of bitter taste receptors and extending into sweet receptor signaling, extraoral tissue expression, and the emerging science of taste-based drug prediction. Niv describes how bitter taste receptors differ structurally from most other GPCRs - missing conserved motifs, more prone to activation, and resistant to pharmacological blockade - and why those properties have shaped both the therapeutic opportunities and the research challenges her lab works on. She traces the receptor-ligand matchmaking problem at the heart of the field: 25 subtypes, thousands of known bitter compounds, and a network of associations that a machine learning recommendation system is now beginning to map. The conversation also covers what happens when taste pharmacology intersects with drug development - a collision that, for most of pharmaceutical history, has occurred too late. Niv's early exposure to bitterness as a formulation problem rooted her work in a question that still matters every time a patient refuses a pill. ABOUT THE GUEST Masha Niv is associate professor and vice dean of research and development at the Hebrew University of Jerusalem's Faculty of Agriculture, Food and Environment, located in Rehovot. A computational pharmacologist by training, she built BitterDB - the first dedicated database of bitter compounds - and has mapped the structural and chemical properties governing ligand promiscuity across all 25 human bitter taste receptor subtypes. Her lab uses homology modeling, machine learning, and collaborative sensory experiments to predict bitterness, identify antagonists, and understand how taste GPCRs function in tissues far from the tongue. She was also a key contributor to the GCCR consortium's large-scale chemosensory research during the COVID-19 pandemic. SCIENTIFIC THEMES OF THE CONVERSATION The architecture of bitter taste receptor diversity - 25 subtypes, ligand promiscuity, and the challenge of orphan receptors with no known ligand Extraoral expression of taste GPCRs - physiological roles in the airways, gut, heart, and cancer tissues Receptor-ligand matchmaking - applying recommendation system logic to the bitter taste receptor family Sweet taste receptor biology and the heavy water paradox - what a single atomic substitution reveals about receptor sensitivity Bitterness as a drug development variable - machine learning prediction, formulation consequences, and the FDA's late entry into the conversation COVID-19 and chemosensory science - how a global consortium formed from a handful of tweets and what it found about taste and smell loss KEY INSIGHTS FROM THE CONVERSATION 1. Bitter taste receptors are built to activate, not to be blocked Bitter taste GPCRs are structurally unusual within the broader GPCR family - they lack several conserved motifs and disulfide bridges present in most other subfamilies. Niv argues this architecture reflects evolutionary logic: a receptor whose job is to detect potential toxins before consumption should be maximally sensitive to activation. The cost is that finding antagonists for these receptors has proven far more difficult than finding agonists, a pharmacological asymmetry her lab is actively working to resolve. 2. Bitterness and toxicity are not the same thing - and the field had to prove it A long-standing assumption in both traditional medicine and drug development treated bitterness as a proxy for toxicity. Niv's work directly challenged that correlation: many intensely bitter compounds are non-toxic, and many toxic compounds are not bitter at all. Recognizing that distinction opened space for a more nuanced view of bitter compounds in nutrition and pharmacology - including the possibility that some bitterness in diet is associated with health benefit, not harm. 3. The drug bitterness blind spot persisted for decades because no one built the right tool early enough Drug discovery workflows screen extensively for efficacy, safety, and pharmacokinetics - but bitterness prediction was rarely incorporated until clinical or even post-market stages. Niv's lab developed a machine learning predictor trained on intensely bitter compounds that can flag bitterness risk from chemical structure alone, early in the development pipeline. The FDA recently made taste reporting a formal requirement, a regulatory shift Niv sees as overdue. 4. A single atomic change in water is enough to activate the sweet taste receptor Deuterated water - in which hydrogen is replaced by the heavier isotope deuterium - produces a measurable sweet signal in sensory experiments. Niv's lab showed that this response depends on the T1R2/T1R3 heterodimer sweet taste receptor: a known receptor inhibitor suppresses the sweetness of heavy water. What makes this finding unusual is the magnitude of the effect relative to the size of the chemical change - the mechanism is still under investigation, but the receptor involvement is established. 5. Taste receptor expression throughout the body reshapes the meaning of drug off-targets Bitter taste receptors are expressed not only in taste receptor cells on the tongue but in the upper airways, gut, heart, and certain cancer tissues. This extraoral distribution has practical consequences: drugs targeting other receptors may be inadvertently activating bitter taste GPCRs in the lung or intestine, contributing to effects that were never attributed to the right target. Niv sees this as one of the more underexplored dimensions of polypharmacology. 6. COVID-19 taste loss was a scientific detour that became something larger Niv had not planned to work on COVID-19 - she had never worked on viruses and was cautious about entering a field she did not know. When reports of taste impairment emerged, she felt obligated to contribute. A small cluster of Twitter exchanges became email threads, became a Slack workspace, became the GCCR consortium - a rapid-assembly international collaboration that surveyed tens of thousands of patients and found that while both smell and taste are impaired in the majority of symptomatic cases, smell loss is the stronger diagnostic signal. 7. The matchmaking problem - and why recommendation systems belong in receptor pharmacology With 25 subtypes, thousands of known bitter ligands, and a matrix of partial associations, the question of which compound activates which receptor is too large and too sparse for classical screening alone. Niv's lab is developing a recommendation system - trained on known receptor-ligand pairs and the structural properties of both - that can suggest candidate receptors for any new compound. The analogy she uses is direct: the system works the way a streaming platform learns your preferences from what similar users have watched.

They're missing some of the conserved motifs, some of the disulfide bridges. I think it has something to do with their architecture that makes it easier to activate them." "I often tell new PIs that the fact that I had to choose a topic with a specific flavor - that actually was good for me. Because that kind of made for me a niche which would be different from what my postdoc lab was doing." "It's such a small change and you get this effect. We know that the sweet taste receptor is involved - and how exactly, that is ongoing." "Let's not think about bitter as something just to get rid of, or try to put a lot of sugar on top of it so you don't feel it. Instead, try to get used to it - and accept that it's actually not bad."
