One group in the model was treated with anti-PD1 ... As only a few numbers of studies have clearly demonstrated the direct coupling of PAR2 to specific Gα isoforms23,24,25, we first established the profile of Gα subunits activated by human PAR2 (hPAR2) using a BRET2-based assay platform in human embryonic kidney 293 (HEK293) cells. We took advantage of an … See more To further characterize the signaling profile of hPAR2, we evaluated its ability to activate downstream effectors of G proteins. We first evaluated the coupling of … See more We characterized the recruitment of βarrestin2 at the plasma membrane upon hPAR2 stimulation using enhanced bystander BRET (ebBRET) monitoring … See more I-287 (Fig. 3a) was discovered by Vertex Pharmaceuticals as a potent inhibitor of PAR2, as part of a drug discovery research program aimed at identifying novel … See more Given the functional selectivity of I-287 toward Gq vs. Gi, we further investigated the effect of this NAM on the activation of Gαq, Gαi2, GαoA, Gα12, and Gα13 using … See more fancy finds semmes al
