Welcome back GPCR Fans,
Clean data can still mislead if the underlying assumptions aren’t tested. Schild analysis is one of the few tools that tells you whether your “competitive antagonist” is actually behaving competitively. This week, we help you tighten your interpretations and strengthen your decisions at the bench and in discovery.
Breakthroughs this week: McGPCR multimodal model; Endocrine Metabolic GPCRs 2026; Pfizer–Metsera acquisition.
This Week in Premium: Sneak Peek
Industry insights: Domain CMO; Pfizer–Metsera; Novo Nordisk strategy shifts.
Upcoming events: GPCR-TDD Europe; Pharmacology 2026.
Career opportunities: GPCR Biology; Protein Science.
Must-read publications: OX2R dynamics; GPR68 nociception.
Terry’s Corner: Schild Analysis — Why It Matters
Most assays show a clean rightward shift and we assume “competitive antagonism.” But if the underlying criteria aren’t tested, that assumption can quietly erode the reliability of your conclusions.
In this week’s lesson, Dr. Kenakin breaks down why Schild analysis remains the gold standard for verifying true competition — and why misclassification propagates error across affinity estimates, mechanism claims, and downstream modeling.

What you’ll gain
Validate the model behind the data. Use the four canonical criteria to distinguish genuine orthosteric antagonism from apparent shifts that mask allosterism or non-equilibrium.
Quantify affinity you can defend. Apply dose-ratios and Schild regressions to derive Kᴮ or pA₂ values that won’t collapse under scrutiny.
Catch subtle mechanistic drift. Diagnose hidden effects like mixed receptor systems or slope deviations before they distort your interpretation.

Dr. GPCR Podcast: Visualizing GLP-1 & GIP Receptors in Islets and Brain
Understanding incretin biology depends on more than ligand potency — it hinges on where receptors actually are, how they internalize, and how tissues interpret signals in real time.
In this conversation, Prof. David Hodson walks through how his team uses fluorescence tools and chemically engineered ligands to map receptor distribution, internalization, and engagement across pancreatic islets and brain circuits.
The result is a clearer view of how incretin-based therapies act in complex metabolic environments.
Why this matters
Receptor distribution shapes incretin hormone drug effects across islets and neural circuits.
Visualization tools redefine our understanding of signaling in intact metabolic tissues.
Fluorescent ligand engineering clarifies receptor behavior that cell lines can’t reveal.
Who should listen
Researchers navigating complex datasets, balancing innovation with assay rigor, or working across chemistry–pharmacology–physiology interfaces will find this episode particularly relevant.
This conversation is part of a three episode series produced in collaboration with our partners at Celtarys Research.
