Watch Episode 172 The Bigger Picture: GPCR Science Meets Public Health At its core, Catherine Demery’ research  is about receptors and signaling pathways—how mu-opioid  and alpha-2 adrenergic receptors  interact For scientists, this means rethinking how we study GPCR-mediated respiratory depression. For scientists, they sharpen our understanding of how different GPCR systems interact to produce respiratory In other words, this is GPCR science with immediate, life-or-death consequences.

There were several sections, among them one specific for GPCRs. Sometimes when you’re in the field you forget the importance GPCRs holds in drug development as a whole Session 4 on Wednesday was dedicated to GPCRs. The talks given targeted both traditional GPCRs such as the serotoninergic receptor 5HT1A, but also newer

We further demonstrate using NMR spectroscopy that a polyproline motif within arrestin-3 interacts directly To provide a framework for this interaction, we determined the crystal structure of the Fgr SH3 domain This model suggests that Fgr interacts with arrestin-3 at multiple sites and is consistent with the locations

Numerous physiological effects of melatonin are mediated via its specific G protein-coupled receptors (GPCRs melatonin receptors are expressed on airway smooth muscle; whether they regulate intracellular cyclic AMP (cAMP) and calcium concentrations ([Ca2+]i), which modulate airway smooth muscle tone; and whether they human and guinea pig airway smooth muscle and cultured human airway smooth muscle (HASM) cells by RT-PCR or the nonselective MT1/MT2 agonist ramelteon (10 µM) significantly inhibited forskolin-stimulated cAMP

Neuropeptides and their specific receptors (primarily G protein-coupled receptors, GPCRs) regulate multiple A total of 41 neuropeptide GPCR genes belonging to three classes were also identified.

When a drug outlives its exposure , toxic interactions can be just as persistent as therapeutic ones. Such interactions can disrupt metabolic detoxification and lead to delayed, systemic toxicity. Irreversible binding can turn enzyme interactions into make-or-break kinetic events. Kenakin with your own enzyme or GPCR interaction puzzles. If you’re not designing with persistent enzyme interactions in mind, you’re building risk into your molecule
