While traditional drug discovery programs have focused on the development of ligands targeting the binding site of endogenous ligands (orthosteric site), allosteric modulators offer new avenues for the regulation identification of multiple allosteric sites and significantly enhanced our understanding of how allosteric ligands systematic analysis of the currently available GPCR structures in complex with small-molecule allosteric ligands in terms of the location of allosteric pockets, receptor-ligand interactions, and the chemical features

2022 Identification of A2BAR as a potential target in colorectal cancer using novel fluorescent GPCR ligands We selected the adenosine receptor 2B (A2BAR), specifically expressed in cancer cell lines compared with stromal cells, to explore the use of fluorescent ligands that can be used for target visualization. expression of A2BAR in CRC cell lines. As well, fluorescent ligands were effective at monitoring real-time A2BAR receptor labeling using live-imaging

In particular, focus lies on the mechanism behind the techniques, and the specific advantages and challenges that one should consider when attempting to compare functional outcomes from different studies, both linked to the specific assay mechanism and linked to its specific execution, as these may heavily impact the

cell-induced inflammation "Gut intraepithelial lymphocytes (IELs) are thought to calibrate glucagon-like peptide 1 (GLP-1) bioavailability, thereby regulating systemic glucose and lipid metabolism. -1RAs require the gut IEL GLP-1R to selectively restrain local and systemic T cell-induced, but not lipopolysaccharide-induced Such effects are mediated by the suppression of gut IEL effector functions linked to the dampening of These data reposition key roles of the L cell-gut IEL GLP-1R axis, revealing mechanisms linking GLP-1R

September 2022 "The complement fragment C5a is one of the most potent proinflammatory glycoproteins liberated C5a is established to interact with a set of genomically related transmembrane receptors, like C5aR1 structure of C5aR2 and its interaction specificity toward C5a is not structurally elucidated in the literature

understanding why two drugs with similar affinity may behave completely differently , and how the secret lies Ligands don’t just “bind”—they change  the receptor. These sites don’t behave like traditional active sites. Ligands may take hours to equilibrate , even when they look potent on paper. What If the Same Site Behaves Differently Depending on the Ligand?

Can we leverage structural and computational insights not just to explain receptor–ligand interactions after the fact, but to forecast outcomes and design ligands with new properties? When existing compounds are exhausted, bespoke ligands are designed and synthesized in-house. Common questions in the group include: Can we forecast ligand efficacy or selectivity? But part of their rigor lies in restraint.

Receptors in Hepatic Stellate Cells and Approaches to Anti-Fibrotic Treatment of Non-Alcoholic Fatty Liver Disease The prevalence of non-alcoholic fatty liver disease (NAFLD) is globally increasing. Like many other organs, various GPCRs play a role in regulating liver function. It is predicted that more than 50 GPCRs are expressed in the liver. of the liver is very limited.

In particular, we focus on the application of on-cell NMR spectroscopy to characterize ligand interactions techniques allow for quantification of binding affinities, competitive binding assays, delineation of ligands involved in binding, ligand bound-state conformational determination, evaluation of receptor structuring and dynamics, and inference of distance constraints characteristic of the ligand-receptor bound state

The ligand does not “block” or “replace” another ligand; it biases the population of receptor states.
