We examined chemokine receptors for the ability to facilitate the infection
of CD4-expressing cells by viruses containing the envelope glycoproteins of
a pathogenic simian immunodeficiency virus, SIVmac239. Expression of either
human or simian C-C chemokine receptor CCR5 allowed the SIVmac239 envelope
glycoproteins to mediate virus entry and cell-to-cell fusion. Thus,
distantly related immunodeficiency viruses such as SIV and the primary
human immunodeficiency virus type 1 isolates can utilize CCR5 as an entry
cofactor.
