Abstract

The lentiviral accessory protein, Vpx, is known to counteract a restriction factor that is specific to myeloid cells, such as macrophages and dendritic cells. This review summarizes the findings in two seminal studies that identify SAMHD1 as the cellular protein that is responsible for myeloid cell restriction, and establish the existence of other types of restriction in these cells.

Keywords: Cullin4; DCAF-1; HIV; SAMHD1; SIV; Vpx; dendritic cell; macrophage; myeloid cell; ubiquitin.
