Unregulated production of virus and/or sperm specific anti-idiotypic antibodies as a cause of AIDS.

A network of idiotypic and anti-idiotypic antibodies is often suggested as the basis for cellular interactions that maintain a steady-state immunological equilibrium. This hypothesis proposes that repeated exposure to certain external antigens--ie, both viral and sperm--stimulates an unregulated production of a uniquely potent immunomodulating idiotypic antibody(ies). In a genetically predisposed individual, this particular antibody(ies), which is also an autoantibody(ies), results in a cellular immune deficiency. This disruption in the immune system permits opportunistic infection and thus the acquired immune deficiency syndrome. This hypothesis, which is readily testable and which does not involve a primary pathogen, can explain both the active induction of this disease in, as well as its passive transfer to, all at-risk populations.
