Characterization of an HIV-1 group M variant that is distinct from the known subtypes.

abstract：:Previous studies have suggested that the abilities of human immunodeficiency virus type 1 (HIV-1) to infect primary macrophages and transformed T cell lines are mutually exclusive and define an important biological distinction among HIV-1 strains. In a survey of eight macrophage-tropic HIV-1 strains and nine T cell li...
