Obesity-induced changes in human islet G protein-coupled receptor expression: Implications for metabolic regulation G protein-coupled receptors (GPCRs) are a large family of cell surface receptors that are the targets for many different classes of pharmacotherapy. The islets of Langerhans are central to appropriate glucose homeostasis through their secretion of insulin, and islet function can be modified by ligands acting at the large number of GPCRs that islets express. The human islet GPCRome is not a static entity, but one that is altered under pathophysiological conditions and, in this review, we have compared expression of GPCR mRNAs in human islets obtained from normal weight range donors, and those with a weight range classified as obese. We have also considered the likely outcomes on islet function that the altered GPCR expression status confers and the possible impact that adipokines, secreted from expanded fat depots, could have at those GPCRs showing altered expression in obesity.

September 2022 GPR84 signaling promotes intestinal mucosal inflammation via enhancing NLRP3 inflammasome The fact that GPR84 expression in leukocytes is remarkably increased under acute inflammatory stimuli Here we demonstrate that GPR84 is highly upregulated in inflamed colon tissues of active ulcerative colitis GPR84 activation imposes pro-inflammatory properties in colonic macrophages through enhancing NLRP3 inflammasome These results define a unique role of GPR84 in innate immune cells and intestinal inflammation, and suggest
