Infection of the brain with human immunodeficiency virus 1 (HIV-l) often leads to the devastating loss of mental faculties. Surprisingly, HIV-1 elicits such brain dysfunction without significantly infecting neurons, astrocytes and oligodendroglia. The target for HIV-1 in the brain is the macrophage, which usually functions as a phagocytic, antigen-presenting and immune-regulatory cell. How can these cells produce such serious cognitive and motor brain impairments? Here. Hans Nottet and Howard Gendelman propose that HIV-1 penetrates the blood-brain barrier inside differentiating macrophages, which become immune activated once inside the brain, and secrete high levels of neurotoxins. Chronic, subclinical disease results by astrocyte regulation of macrophage effector functions. Ultimately, endogenous control mechanisms break down, leading to motor and mental impairments in some affected subjects.A third of the adults and half of the children with AIDS will inevitably develop neurological impairments directly attributable to human immunodeficiency virus 1 (HIV-l) infection of the central nervous system (CNS). A range of clinical and pathological disease manifestations of HIV-l infection of the brain and spinal cord’(termed, collectively, the HIV-l-associated cognitive/motor complex or HIV dementia) is a prominent feature of AIDS (Ref. 2). Disease is often subtle, and includes mental and physical slowing, and diminished cognition. Complaints of overt memory loss and difficulties with reading or carrying out simple tasks at work and/or at home can follow. Motor symptoms may occur concomitantly and are manifested by clumsiness progressing to gait disturbances with profound weakness. Inevitably, florid dementia with incontinence, hallucinations, seizures, then comas ensues;.
