Variation in HIV-1 R5 macrophage-tropism correlates with sensitivity to reagents that block envelope: CD4 interactions but not with sensitivity to other entry inhibitorsPaul J Peters
Center for AIDS Research, Program in Molecular Medicine and Department of Molecular Genetics and Microbiology, 373 Plantation Street, University of Massachusetts Medical School, Worcester, MA 01605, USA
Retrovirology 5:5. 2008..These R5 envelopes conferred a wide range of macrophage tropism and included highly macrophage-tropic variants from brain and non-macrophage-tropic variants from lymph node...
Non-macrophage-tropic human immunodeficiency virus type 1 R5 envelopes predominate in blood, lymph nodes, and semen: implications for transmission and pathogenesisPaul J Peters
Center for AIDS Research, Program in Molecular Medicine, University of Massachusetts Medical School, 373 Plantation St, Biotech II Suite 315, Worcester, MA 01605, USA
J Virol 80:6324-32. 2006..The extensive variation in R5 tropism reported here is likely to have an important impact on pathogenesis and on the capacity of HIV-1 to transmit...
Biological analysis of human immunodeficiency virus type 1 R5 envelopes amplified from brain and lymph node tissues of AIDS patients with neuropathology reveals two distinct tropism phenotypes and identifies envelopes in the brain that confer an enhanced Paul J Peters
Program in Molecular Medicine and Department of Molecular Genetics and Microbiology, University of Massachusetts Medical School, Worcester MA 01605, USA
J Virol 78:6915-26. 2004..These envelopes are able to infect cells that express low levels of CD4 and/or CCR5 and may have adapted for replication in brain macrophages and microglia, which are known to express limited amounts of CD4...
Inhibition of CCR5-mediated infection by diverse R5 and R5X4 HIV and SIV isolates using novel small molecule inhibitors of CCR5: effects of viral diversity, target cell and receptor densitySamantha Willey

Antiviral Res 68:96-108. 2005..The extent of inhibition was dependent on cell type and on cell surface CCR5 concentration. Our results underscore the potential of CCR5 inhibitors for clinical development...
A conserved determinant in the V1 loop of HIV-1 modulates the V3 loop to prime low CD4 use and macrophage infectionThomas Musich
University of Massachusetts Medical School, Worcester, MA 01605, USA
J Virol 85:2397-405. 2011..In summary, we show that a conserved determinant in the V1 loop modulates the V3 loop to prime low CD4 use and macrophage infection...
