The effects of anti-inflammatory drugs on glial immunity and neuropathology were determined in a severe combined immune deficiency (SCID) mouse model of HIV-1 encephalitis. HIV-1-infected human monocyte-derived macrophages (MDM) are stereotactically inoculated into basal ganglia resulting in a multinucleated giant cell encephalitis. A platelet activating factor antagonist and a matrix metalloproteinase inhibitor, which also inhibits tumor necrosis factor alpha release, were administered to animals at the time of the MDM inoculation. The drugs administered in combination markedly reduced brain inflammation, astrogliosis and microglia activation. These findings demonstrate that reduction of brain inflammatory responses, independent of viral replication, can affect HIVE pathology in an animal model system of disease.
