pubmed:abstractText
HIV enters the brain soon after virus exposure but elicits profound neurological deficits in infected humans years later usually during progressive immunosuppression and the development of the acquired immune deficiency syndrome. The neurological disease complex associated with virus infection occurs in a large proportion of infected patients and is commonly referred to as HIV-1 associated dementia complex. The neuropathogenesis of central nervous system/viral infection revolves around mononuclear phagocytes (brain macrophage/microglial) infection and immune activation in brain. Macrophages secrete neurotoxic factors that elicit neuronal injury and inevitably death leading to the constellation of cognitive and motor impairments common during progressive disease. Neurotoxic factor production requires virus entry and replication, the evolution/selection of neurovirulent HIV-1 strains and the production of viral and cellular immune factors injurious to human neurons. Interestingly, neurological deficits, the HIV-1 associated neuropathology and viral replication disease are not always associated. This has led to the notion that viral replication induces the autocrine/paracrine production of cellular/viral factors leading to a metabolic encephalopathy. Anti-retroviral and anti-inflammatory therapies should prove increasingly beneficial for treatment and, ultimately, reversal of HIV-1 associated dementia complex in the affected human host.
