17,18likely associated with multiple receptor conformations. Biased signalling refers to the ability of different ligands binding to the same receptor but engage with different signalling complexes, triggering differential cellular responses19. Amongst the large number of PAMs that have been...
15). We hypothesize that the observed conformations of the holoreceptor can activate a certain signaling pathway while the same conformations are inactive for the other signaling pathways and vice versa. This potential signaling bias opens new directions for further studies on aGPCRs. An ECR-...
2 Effect of targeting the Gαs/PKA signaling pathway in CD8 T cells. a, Upregulation of inhibitory receptors and decrease of IFNγ and TNF in chronically versus acutely simulated CD8 T cells. The average relative expression and s.e.m. are shown (n = 6 biologically independent samples...

a, rpS6 phosphorylation is a robust and sensitive readout for mTORC1 activation using leucine and various known inhibitors of the mTORC1 pathway. Hs68 cells were starved of serum and amino acids for 2.5 h and restimulated as indicated. Images were quantified by CellProfiler, and the integrat...
