abstract：:Persistent tumour necrosis factor alpha (TNF-alpha) exposure uncouples proximal T-cell receptor (TCR)-signalling events. Here, we demonstrate that chronic TNF-alpha exposure also attenuates signalling distal to the TCR, by specifically inhibiting Ca2+ influx evoked by thapsigargin in CD4+ T-cells. Mitogen-induced Ca2+...
