WebJan 8, 2024 · G protein-coupled receptors (GPCRs) usually regulate cellular processes via activation of intracellular signaling pathways. However, we have previously shown that in several cell lines, GqPCRs induce immediate inactivation of the AKT pathway, which leads to JNK-dependent apoptosis. WebThe protein tyrosine phosphatase (PTP) CD45 is critical in regulating the earliest steps in T-cell-receptor signaling but, similar to all PTPs, it is susceptible to oxidative inactivation. Given the widely reported effects of oxidant damage associated with rheumatoid arthritis (RA), we examined whether CD45 phosphatase activity was altered
