- AB Neurobehavioral and pathological data indicate that the central nervous
- system (CNS) becomes infected with HIV-1 soon after the virus enters the
- body. However, neuropathogenesis of HIV-1 infection is difficult to
- investigate because the brain parenchyma is not accessible to sampling
- during the course of AIDS. The second compartment of the CNS,
- cerebrospinal fluid (CSF), is accessible to sampling but how changes in
- the CSF relate to the changes in the parenchyma is poorly understood.
- Thus, knowledge of the neuropathogenesis of HIV-1 infection
- predominantly stems from either postmortem or in vitro studies. This
- raises the need for animal models of HIV infection of the CNS. Such
- models have been developed and are briefly reviewed here. The models
- faithfully recapitulate some aspects of the HIV/CNS disease. Appropriate
- neuropathological changes and neurobehavioral dysfunction (e.g.,
- cognitive and motor deficits) occur in SIV-infected macaques. Central
- sensory electrophysiological changes and sleep disturbances occur in
- FIV-infected cats. Infection of the brain and behavioral changes
- comparable to some of the changes seen in humans occur in mice infected
- with a mixture of murine leukemia viruses. Genetically immunodeficient
- mice (e.g., SCID) accept HIV-infected human organs and or cell grafts.
- Evidence summarized here indicates that these HuSCID animals undergo
- neuropathological changes similar to those observed in brains of
- individuals who died with AIDS. Thus, presently available animal models
- provide an opportunity to investigate HIV/CNS disease, and to develop
- and test therapeutic interventions to prevent or cure the disease.
