 note = {Expressions of the effector molecules of Fas-mediated apoptosis in primary cultured salivary gland epithelial cells (SGEC) of primary Sjogren's syndrome (pSS) remain to be clarified. We focused on Fas-mediated caspase cleavage compared to tumor necrosis factor-related apoptosis inducing ligand (TRAIL)-mediated apoptosis. Induction of apoptosis was performed by anti-Fas antibody coupled with PI3K inhibitor, or TRAIL. Activation of caspases, cytochrome C, and apoptotic protease activating factor-1 (Apaf-1) was determined by western blotting or immunofluorescence observed by confocal microscopy. Fas-mediated apoptosis and activation of caspase 3/8 were induced in the presence of LY294002. TRAIL-induced apoptosis in SGEC, which was stronger than that induced by anti-Fas antibody. TRAIL-induced caspase 9 cleavage accompanied by activation of cytochrome C and Apaf-1 were not mediated by anti-Fas antibody. Our results suggest that death receptor-dependent apoptosis in primary cultured SGEC is regulated by the engagement of type II cells in pSS., Apoptosis, 13(11), pp.1322-1330; 2008},
