HIV-1 Vpr combats the PU.1-driven antiviral response in primary human macrophages.

The HIV-1 accessory protein, Vpr, is an enigmatic protein required for efficient spread of HIV from macrophages to T cells, a necessary step for propagation of infection. To illuminate the role of Vpr in HIV-infection of primary macrophages, we used single-cell RNA sequencing to capture the transcriptional changes during an HIV-1 spreading infection plus and minus Vpr. We found that Vpr reprogramed HIV-infected macrophage gene expression by targeting the master transcriptional regulator, PU.1. PU.1 was required for efficient induction of the host innate immune response to HIV, including upregulation of
