| heal.abstract | The course of human immunodeficiency virus 1 (HIV-1) infection in human infant microglia was studied using purified primary cultures of microglia derived from brain autopsy tissue. Previous in vitro studies have used fetal or adult brain tissue. Important differences may exist between brain tissues of different maturational ages with regard to HIV-1 replication and other neuropathogenic effects. Infant microglia were infected with four different strains of HIV-1 (JR-FL, JR-CSF, Ba-L, and IIIB). Productive infection was demonstrated by p24 antigen production, immunocytochemistry, and recovery of replication-competent virus from the supernatants of the infected cultures. Multinucleated giant cells developed in culture mimicking the neuropathological changes seen in the brains of patients with HIV encephalopathy. Productive infection was more readily established by monocyte-tropic strains (JR-FL and Ba-L) of HIV-1 than by a lymphocyte-tropic strain (IIIB). p24 antigen production in this system peaked at 47 to 51 days postinfection. Viral persistence in giant cells was demonstrated by immunocytochemistry for the gp120 and gp41 viral antigens as late as 70 days postinfection. This in vitro culture system, using infant microglia that support viral replication for more than 2 months, may provide a useful model for studying the pathogenesis of progressive HIV encephalopathy. | en |
