It wasn’t until his postdoctoral years at UCSF—under Brian Shoichet—that GPCRs entered his scientific This scarcity made the field both exciting and high-risk. asked whether a compound is twice as potent as another, he’s quick to point out the limitations in both

Antonella Di Pizio’s lab , there was almost nothing—no team, no culture, not even proper desks. Over the years you see the lab establishing, and for both of us, of course, growing.”

Except: Nothing behaved. Receptor access was unpredictable. Tissue responses defied the model. It enabled: Live-tissue visualization Cell-type-specific receptor mapping Validation in both the periphery

When executed as a unified pipeline, these phases ensure an HCS assay capable of supporting both exploratory Their ability to visualize ligand–receptor interactions directly in living cells produces data that are both Visual + Quantitative Data Fluorescent ligand assays generate both numerical values (IC₅₀, Kᵢ) and spatial Lin S, Schorpp K, Rothenaigner I, Hadian K. Image-based high-content screening in drug discovery.

. 👉 Founders often look back and say that nothing felt broken. The science was sound. It is structural. 👉 Biotech startup failure of this kind is difficult to spot precisely because nothing Nothing has collapsed. Metrics may even look acceptable. Over time, this sideways motion becomes costly, both financially and organizationally. 👉 By the time

in β-arrestin recruitment across class B1 GPCRs  – GPCR mutations in cancer—drivers, passengers, or both Research presents CELT-419, a nanomolar-affinity fluorescent ligand optimized for D3 receptor assays in both GPCR mutations in cancer   show both driver-like patterns and high redundancy, prompting a call for multiomics

Matters Connect with peers across biotech, CROs, and investment who are driving discovery forward Meet both identification, target validation, assay development, compound management, and high-throughput screening in both Screening campaigns can be performed using Axxam’s high-quality compound collections—both synthetic and

especially those emerging from cytotoxicity or off-target activities, risks catastrophic consequences for both A scaffold exhibiting hERG inhibition is an immediate candidate for discontinuation, as the risk is both Kenakin clarifies that both direct hepatotoxic effects and conditional toxicities, such as those driven

Without a clear biotech positioning, there is nothing to anchor the conversation. increases confidence and coherence Alignment can be tested quickly , saving time and emotional energy on both External conversations become easier because both sides know what is being evaluated.

Serafini noted that RGS4 was especially intriguing because it was expressed robustly both in the peripheral system and in central circuits like the prefrontal cortex and thalamus  — areas deeply involved in both

Studies on MC4R show that both the agonist alpha-MSH and the antagonist AgRP drive receptor internalization The model needs to account for the possibility that both arms of the pharmacological response — activation Diffusion-enhanced resonance energy transfer extends this further by capturing both internalization and

trip to London, confocal imaging marathons, and a partnership built on trust and curiosity — reshaped both fluorescent probes, how he evaluated biological constraints, and how he approached GPCR imaging as both Over the years, they learned from each other in ways that shifted both careers. experiments that capture receptor dynamics in intact tissue and live animals, expanding what’s possible in both

C GPCRs, are obligate dimers, either as homodimers or heterodimers, with distinct conformations in both Recent studies suggest that class B1 GPCRs can form both homodimers and heterodimers, which may play that GLP-1R homodimerization occurs via transmembrane helix 4 (TM4), which forms the interface for both result, dimerized SecR receptors exhibit higher rates of G protein activation and release, improving both

When Everything Is Strategic, Nothing Is Decisive 👉 Strategic overload starts with reasonable decisions Nothing is formally deprioritized. Nothing is clearly paused. Everything remains alive. If nothing is clearly paused, the strategy is likely overloaded. 5️⃣ Stress test the narrative under

why teamwork is non-negotiable) The difference between Me Too  and First in Class  projects—and why both

October 2022 "The activity of dopamine neurons is dependent on both intrinsic properties and afferent applications of sub-saturating concentrations of agonists where the co-application of one agonist resulted in both results suggest that the cooperative interaction between G βγ subunits and GIRK channels determines both Coincident activation of D2 and GABAB receptors leads to facilitation of GIRK channel currents, augmenting both

Canceling the Cell If observed potency reflects both drug properties and system sensitivity, then system Kenakin outlines a practical solution: use a potency metric that incorporates both efficacy and EC₅₀ If pathway-specific readouts are used to define receptor selectivity, then both agonists must be evaluated

They both mark critical moments in humanity’s centuries-long quest to control physiology—and they bookend

The cytoskeletal protein filamin A (FLNA) directly interacts with both somatostatin receptor type 2 ( A7), and octreotide but not pasireotide promoted hetero-dimerization in both A7 and M2 (+20.0 ± 11.8% On the contrary, in M2 cells, octreotide failed to internalize both receptors whereas pasireotide promoted In conclusion, we demonstrated that in GH3 cells SST2 and SST5 can form both homo- and hetero-dimers

Additionally, we employed optical assays in living cells to thoroughly profile both GPR35 isoforms for basis for this bias, we examined structural models of GPR35 and conducted experiments with mutants of both found that a proposed disulfide bridge between the N-terminus and extracellular loop 3, present in both

mirrors what’s happening now in other parts of the field: platforms replacing isolated tools, enabling both And those who understand both the legacy and the future of GPCR work are the ones shaping the next era

However, controversy remains regarding its role in breast cancer since both pro- and anti-metastatic We show that both cell lines express KISS1R mRNA and respond to KP-10 by elevating calcium mobilisation Interestingly, both cell lines displayed different complements of β-arrestin 1 and 2 expression.

single-domain antibody fragments from camelids, have become indispensable tools for interrogating GPCRs both technologies to discover nanobodies with tailored specificities may expand the impact of these tools for both

proteomics revealed that in the interactome of VLGR1, molecules are enriched that are associated with both mitochondria, as well as mitochondria-associated ER membranes (MAMs), a compartment at the contact sites of both
