Abstract

HIV protein gp120 in combination with T cell antigen receptor (TCR) triggering induces apoptosis (gp120-apoptosis) in Th1 cells. Gp120-apoptosis occurs by induction of Fas-L and subsequent triggering of the Fas apoptotic pathway. Here, through the use of several compounds inhibiting induction of Fas-L, we show that, in a Th1 clone, a protein kinase C (PKC) independent pathway activated by TCR stimulation is distinguishible from a PKC dependent pathway activated by either phorbol 12-myristate 13-acetate (PMA)/ionomycin or asynchronous stimulation of TCR and CD4 as occurs in gp120-apoptosis.
