title: [Brief analytical review of additional possible mechanisms in the pathogenesis of AIDS].
abstract: It is generally agreed that HIV itself has the primary role in the initiation and propagation of the pathogenic process of the infection. Nonetheless, a number of important issues concerning the pathogenesis of HIV infection remain unresolved. For example, it remains unclear how CD4+ T cells are lost after HIV infection. The low frequency of infected cells seen even in advanced infection implies that a direct cythopathic effect of HIV on infected CD4+ T cells cannot explain their disappearance. Multiple and diverse mechanisms have been proposed as supplements to the HIV in the destruction of CD4+ cells and the pathogenesis of AIDS. However, it is not yet possible to state confidently which additional mechanism(s) is important. Identification of the nature of this supplemental process has become essential for successful, non-harmful intervention. We propose here a short analytical review of the possible supplemental mechanisms of immunological destruction in AIDS in order to emphasize the complexity of the pathogenesis of the disease.
