title: Infectious DNA clone of HIV type 1 A/G recombinant (CRF02_AG) replicable in peripheral blood mononuclear cells.
abstract: We constructed an infectious DNA clone of the HIV-1 A/G recombinant 97GH-AG2, which was isolated in Ghana in 1997 and was classified originally as subtype A. By phylogenetic and recombination breakpoint analyses, p97GH-AG2 was grouped in the circulating form of A/G recombinants (CRF02_AG) and was found to contain the least amount of subtype G-derived region among the known CRF02_AG HIV-1 DNAs. This result suggests that CRF02_AG may be a predominant form in Ghana. Virions produced by transfection of p97GH-AG2 into 293T cells grew in phytohemagglutinin-stimulated peripheral blood mononuclear cells (PBMCs). 97GH-AG2 also replicated efficiently in CCR5-expressing HeLa cells, MAGIC5, but only weakly in the parent MAGI cells, indicating that 97GH-AG2 uses mostly CCR5 as a coreceptor. Isolation of the first HIV-1 (CRF02_AG) DNA clone that replicates in PBMCs will accelerate the molecular analysis of this subtype.
