Studies of human immunodeficiency virus type 1 (HIV-1) associated dementia have shown neuronal loss in discrete areas. The presence and mechanism of neuronal death, however, has remained quite elusive. One mechanism of cell death, apoptosis, has been clearly demonstrated outside the central nervous system (CNS) in HIV-1 infection but has not been firmly established within the CNS. Therefore, we set out to ascertain whether neuronal cell loss in simian immunodeficiency virus (SIV) encephalitis, an animal model of HIV-1-associated dementia, is a result of apoptosis.
