Abstract

Acquired immune deficiency syndrome (AIDS) is a disease caused by the human immunodeficiency virus (HIV) in which cellular immune functions are severely impaired. Acute infection and subsequent destruction of helper T cells, although occurring readily in cell cultures, do not appear to be the only mechanisms mediating helper T cell loss. Other mechanisms that may account for the loss of helper T cells include: T cell syncytia formation, decreased T cell production, and autoimmune-related destruction of helper T cells. Immune abnormalities seen early in the course of HIV infection include immune hyperactivation and autoimmune phenomena suggestive of immune dysregulation rather than immune deficiency. Many changes in immune function are, in fact, seen in HIV-seropositive patients who possess a normal number of helper T cells. Mechanisms (other than the loss of helper T cells) that may contribute to the immune abnormalities seen in these patients include noninfectious effects of HIV and HIV proteins, effects of HIV on non-T cells, autoimmune-related manifestations of HIV infection, and HIV-induced activation of normal immunosuppressive circuits.
