FASLG (Fas ligand) and Fas receptor constitute the basic elements in apoptosis. Interaction of FASLG with Fas receptor leads to activation of caspase-8. This caspase in turn leads to activation of effector caspases such as caspase-3, -6 and -7. This cascade results in the hydrolysis of nuclear and cytoplasmic components. Expression of FASLG is induced by nuclear factor-KB (NFKB). NFKB/FASLG pathway facilitates the suppression of p,pμ-DDT (dichlorodiphenoxytrichloroethane)-induced cell toxicity by vitamin C and E. In CD4+ T cells, this protein is expressed on stimulus by T-cell receptor (TCR), both during normal and pathological conditions, such as alcohol exposure.', 'Fas ligand, a protein belonging to the tumor necrosis factor (TNF) family of cytokines, induces apoptosis in cells expressing the cell membrane receptor Fas (CD95/Apo-1).
