Popis: Abnormal function of peripheral blood T lymphocytes is characteristic of RA; diminished proliferation and secretion of cytokines following in vitro mitogen stimulation are observed. We have investigated the calcium flux initiating T cell activation in rheumatoid peripheral blood mononuclear cells (PBMC) to determine whether abnormalities in signalling are also present. We have found that both phytohaemagglutinin (PHA-P)- and anti-CD3-stimulated calcium fluxes were much reduced in the patients’ PBMC compared with controls, with a mean six-fold difference (P
