Blood Monocytes Harbor HIV Type 1 Strains with Diversified Phenotypes Including Macrophage‐Specific CCR5 Virus

Expression of CCR5 increases during monocyte differentiation and directly mediates macrophage susceptibility to infection by human immunodeficiency virus type 1.

The stage of differentiation and the lineage of CD4+ cells profoundly affect their susceptibility to infection by human immunodeficiency virus type 1 (HIV-1). While CD4(+) T lymphocytes in patients are readily susceptible to HIV-1 infection, peripheral blood monocytes are relatively resistant during acute or early infection, even though monocytes also express CD4 and viral strains with macropha...

Productive human immunodeficiency virus type 1 (HIV-1) infection of nonproliferating human monocytes

Human immunodeficiency virus type 1 (HIV-1) infection of T lymphocytes requires cellular proliferation and DNA synthesis. Human monocytes were shown to have low DNA synthesis rates, yet the monocytotropic BaL isolate of HIV-1 was able to infect these cells efficiently. Monocytes that were irradiated to assure no DNA synthesis could also be readily infected with HIV-1BaL. Such infections were as...

Role of the b-Chemokine Receptors CCR3 and CCR5 in Human Immunodeficiency Virus Type 1 Infection of Monocytes and Microglia

Incidence of Human T-Lymphotropic Virus Type 1 (HTLV-1) among Blood Donors from Ilam, Iran

Role of the beta-chemokine receptors CCR3 and CCR5 in human immunodeficiency virus type 1 infection of monocytes and microglia.

Human immunodeficiency virus type 1 (HIV-1) infection in mononuclear phagocyte lineage cells (monocytes, macrophages, and microglia) is a critical component in the pathogenesis of viral infection. Viral replication in macrophages serves as a reservoir, a site of dissemination, and an instigator for neurological sequelae during HIV-1 disease. Recent studies demonstrated that chemokine receptors ...
