Watch Episode 172 The Bigger Picture: GPCR Science Meets Public Health At its core, Catherine Demery’ s research  is about receptors and signaling pathways—how mu-opioid  and alpha-2 adrenergic receptors For scientists, this means rethinking how we study GPCR-mediated respiratory depression. For Catherine, those numbers aren’t just statistics—they’re signals guiding how to build better models In other words, this is GPCR science with immediate, life-or-death consequences.

Biased agonism is a phenomenon where different ligands acting on the same receptor trigger distinct signaling significant attention in drug discovery, especially in the context of G protein-coupled receptors (GPCRs The GLP-1R, a class B1 GPCR, is integral to metabolic regulation, particularly in glucose homeostasis These differences in signaling profiles can have significant physiological implications.
