Dual tropism of HIV-1 envelopes derived from renal tubular epithelial cells of patients with HIV-associated nephropathy

AIDS. 2006 Feb 28;20(4):621-4. doi: 10.1097/01.aids.0000210618.68083.8e.

Abstract

The phenotype of HIV-1 gp120 envelope derived from renal epithelium and peripheral blood mononuclear cells (PBMC) of patients with HIV-associated nephropathy was investigated in vitro. Chimeric viruses were derived from kidney or blood and used to infect primary CD4+T cells, cell lines expressing single co-receptors and a renal epithelial cell line HPT-1. HIV-1 variants derived from renal epithelium were dual tropic whereas simultaneously derived viruses from PBMC were R5-tropic. Utilization of alternative co-receptors CCR3, BONZO and BOB, also differed.
