Figure 3. The role of caspase-8 in maintaining the survival of activated T cells.
Caspase-8 deficient T cells undergo necroptosis in response to antigen stimulation, which can be inhibited by necrostatin-1 (Nec-1). Autocrine secretion of TNFα is hypothesized to mediate necroptosis in activated caspase-8 deficient T cells.
