| PAG Description | HIV infection leads to drastic declines in CD4 T helper cells, in part through apoptosis of uninfected cells. Apoptosis of uninfected cells may be induced through the expression of Fas ligand on the surface of HIV-infected cells, stimulating the Fas-dependent apoptotic pathway in cells that come in contact with infected cells. The NEF protein expressed by HIV may play induce the expression of Fas-ligand by infected cells. If this is the case, then a question that arises is how infected cells themselves escape Fas-mediated apoptosis. The NEF protein appears to play a role in this process as well. NEF interacts with the ASK1 kise (apoptosis sigl-regulating kise) involved in apoptotic sigling by TNF and Fas-ligand. Interaction of NEF with ASK1 prevents phosphorylation of downstream MAP kises and JNK kises involved in apoptotic sigling. |
