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.
