Human microglial cells: Characterization in cerebral tissue and in primary culture, and study of their susceptibility to HIV‐1 infection

Abstract: Neuropathological studies have shown that human immunodeficiency virus type 1-infected cells within the brain express several markers characteristic of macrophages and could either be microglial cells, or monocytes invading the CNS, or both. To better define the target cells of human immunodeficiency virus type 1 within the brain, we have studied human microglial cells, both in vivo and in vitro, and compared them to monocytes for their antigenic markers and their susceptibility to human immunodeficiency virus… Show more

“…The tissue specificities and expression patterns of the human CD11b and CD68 antigens, as well as the murine F4/80, have been analyzed in different types of myeloid cells, and each has been identified as a specific marker of particular myeloid lineages including, to varying degrees, microglia. [25][26][27][28] The regulatory as well as coding sequences of each gene have also been cloned. [28][29][30] The first candidate, CD11b, the a subunit of the CD11b/CD18 integrin adhesion molecule, is not present on the surfaces of immature myeloid precursors, but expression increases during early cell differentiation and is subsequently restricted to mature monocytes, macrophages, neutrophils, natural killer cells, and microglia.…”

“…Similarly to macrophages from other tissues (39,41), they express low levels of CD4 (13,29,57,85), as well as CCR5 and CXCR4 (44). Since viruses isolated from the brain are macrophage tropic and use mainly CCR5 (1,26,71), it is likely that viral tropism for microglia and macrophages is determined by similar mechanisms (3,49,59).…”

“…8oth resistance and susceptibility of microglial cells to infection with HIV has been reported recently from in vitro studies. Attempts to infect microglial cells from human embryonie brain and spinal cord with 1wo differ-· ent strains of HIV-1 were without success (Peudenier et a/., 1991 ). No apparent CPE, p24.…”
