AB We previously reported that pigtailed macaques (Macaca nemestrina)
became infected after intravenous inoculation with the LAI strain of
human immunodeficiency virus type 1 (HIV-1), an isolate that replicates
in both M. nemestrina lymphocytes and blood-derived
monocyte/macrophages. In the current study we investigated the presence
of HIV-1 and pathology in the postmortem brains of four of these
macaques. Histopathological findings revealed focal lesions in white
matter in the frontal and occipital lobes of one macaque, with myelin
loss, nerve fibre loss, and gliosis within these lesions.
Semi-quantitative, solution-based PCR revealed HIV-1 DNA in the brains
of two of the other macaques. Using slide-based PCR-driven in situ
hybridization, we studied these two macaques further and detected
intranuclear, circular HIV-1 DNA in vascular endothelia and other
non-neuronal brain cells. These findings indicate that M. nemestrina
brain can be infected with HIV-1 in vivo and may provide a useful animal
model for understanding early HIV-1 brain infection in humans.
