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

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

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

At a molecular level, different ligands bind to the same receptor and vice-versa (Marcuzzi et al. 2018 Drug discovery is shifting towards the development of biased ligands, which promote the engagement of and signaling patterns, by modulating ligand binding, as well as G-protein coupling or interaction with , unlike most of the class A GPCRs ligands that are small molecules or short peptides. Overall, the future potential lies in using different therapeutic modalities to modulate the stromal
