Interactions of human immunodeficiency virus-1 proteins with neurons: possible role in the development of human immunodeficiency virus-1-associated dementia.
Human immunodeficiency virus-1 (HIV-1)-associated dementia is a severe neurological complication of HIV-1 infection that affects 15-20% of the patients in the late stages of acquired immunodeficiency syndrome. HIV-1-associated dementia is most probably a consequence of HIV-1 infection of the brain rather than of an opportunistic pathogen. The exact mechanism by which the virus causes this disorder, however, is not completely understood. A number of HIV-1 proteins have been shown to be released from HIV-1-infected cells and/or to be present in the extracellular milieu in the HIV-1-infected brain. Moreover, these proteins have been shown to possess neurotoxic and/or neuromodulatory features in vitro. This review describes the possible direct interactions of the HIV-1 proteins gp120, gp41, vpr, tat, rev, vpu and nef with neurons, which might play a role in the development of HIV-1-associated dementia in vivo.
