Prolonged survival of TCR-activated T cells from CIS transgenic mice. (a) TCR-mediated cell death. Concentrations of viable cells were determined in a hemocytometer, and viability was judged by trypan blue exclusion. (b) Reactivation of surviving CD4 T cells after withdrawal of the stimulator, anti-CD3, showing that CIS expression could increase activation and prolong survival of T cell in the absence of stimulator. Anti-CD3 stimulation is indicated by black bars.
