Interferon but not MxB inhibits foamy retroviruses
چکیده انگلیسی
Foamy viruses (FV) are retroviruses that are widely distributed in primate and non-primate animal species. We tested here FV with capsids of simian and non-simian origin for sensitivity to interferon-β (IFN-β). Our data show significant inhibition of FV by IFN-β early in infection of human HOS and THP-1 but not of HEK293T cells. The post-entry restriction of FV was not mediated by the interferon-induced MxB protein that was recently identified as a capsid-interacting restriction factor targeting Human immunodeficiency virus (HIV) before integration. Neither the ectopic expression of MxA or MxB in HEK293T cells nor the lack of MxB expression in CRISPR/CAS MxB THP-1 knockout cells impacted the infection of the tested FV. IFN-β treated THP-1 and THP-1 KO MxB cells showed the same extend of restriction to FV. Together, the data demonstrate that IFN-β inhibits FV early in infection and that MxB is not a restriction factor of FV.
