Reduced amount of programmed cell death in peripheral blood lymphocytes following exposure to CD95 (APO-1/Fas), which is a member of the death receptor family, a subfamily of the TNF-R superfamily. Crosslinking of CD95 with its natural ligand CD95L (CD178) or with agonistic antibodies such as anti-APO-1 induces apoptosis in sensitive cells. [from
