While members of the APOBEC3 family of human intrinsic resistance factors are able to restrict the replication of Vif-deficient forms of human immunodeficiency virus type 1 (HIV-1), they are unable to block replication of wild-type HIV-1 due to the action of Vif, which induces their degradation. In contrast, HIV-1 Vif is unable to block inhibition mediated by APOBEC3 proteins expressed by sever...
HIV-1 persists in peripheral blood monocytes in individuals receiving highly active antiretroviral therapy (HAART) with viral suppression, despite these cells being poorly susceptible to infection in vitro. Because very few monocytes harbor HIV-1 in vivo, we considered whether a subset of monocytes might be more permissive to infection. We show that a minor CD16+ monocyte subset preferentially ...
The mammalian APOBEC3 family of cytidine deaminases includes members that can act as potent inhibitors of retroviral infectivity and retrotransposon mobility. Here, we have examined whether the alpharetrovirus Rous sarcoma virus (RSV) is susceptible to inhibition by a range of human APOBEC3 proteins. We report that RSV is highly susceptible to inhibition by human APOBEC3G, APOBEC3F, and APOBEC3...
BACKGROUND HIV-1 replication depends on a delicate balance between cellular co-factors and antiviral restriction factors. Lens epithelium-derived growth factor (LEDGF/p75) benefits HIV, whereas apolipoprotein B mRNA-editing catalytic polypeptide-like 3G (APOBEC3G), tripartite motif 5alpha (TRIM5α), and tetherin exert anti-HIV activity. Expression levels of these proteins possibly contribute to ...
The gradual accumulation of mutations by any of a number of mutational processes is a major driving force of divergence and evolution. Here, we investigate a potentially novel mutational process that is based on the activity of members of the AID/APOBEC family of deaminases. This gene family has been recently shown to introduce-in multiple types of cancer-enzyme-induced clusters of co-occurring...
