SAMHD1 is a triphosphohydrolase that restricts the replication of HIV-1 and SIV in myeloid cells. In macrophages and dendritic cells, SAMHD1 restricts virus replication by diminishing the deoxynucleotide triphosphate pool to a level below that which supports lentiviral reverse transcription. HIV-2 and related SIVs encode the accessory protein Vpx to induce(More)
The promyelocytic leukemia protein (PML) is the main structural component of the nuclear matrix structures termed nuclear domain 10 (ND10) or PML nuclear bodies (PML-NBs). PML and ND10 structures have been shown to mediate an intrinsic immune response against a variety of different viruses. Their role during retroviral replication, however, is still(More)
