FasL Antibody / Fas Ligand

Cytotoxic T lymphocyte (CTL)-mediated cytotoxicity constitutes an importantcomponent of specific effector mechanisms in immuno-surveillance againstvirus-infected or transformed cells. Two mechanisms appear to account forthis activity, one of which is the perforin-based process. Independently, aFAS-based mechanism involves the transducing molecule FAS (also designated Apo-1) and its ligand (FAS-L). The human FAS protein is a cell surfaceglycoprotein that belongs to a family of receptors that includes CD40, nervegrowth factor receptors and tumor necrosis factor receptors. The FAS antigen is expressed...
