The CD16+ subset of monocytes is dramatically expanded in peripheral blood during progression to AIDS, but its contribution to HIV pathogenesis is unknown. Here, we demonstrate that CD16+ but not CD16− monocytes promote high levels of HIV replication upon differentiation into macrophages and interaction with T cells. Conjugates formed between CD16+ monocyte-derived macrophages and T cells are major sites of viral replication. Furthermore, similar monocyte–T cell conjugates detected in peripheral blood of HIV-infected patients harbor HIV DNA. Thus, expansion of CD16+ monocytes during HIV infection and their subsequent recruitment into tissues such as lymph nodes, brain, and intestine may contribute to HIV dissemination and establishment of productive infection in T cells.
