BST2, bone marrow stromal antigen 2; SARS-CoV, severe acute respiratory syndrome coronavirus SARS-CoV virion release is mitigated by SARS-CoV S, it is possible that a number of enveloped viruses have developed supplementary anti-BST2 factors over time-note that in addition to Vpu, HIV-1 Nef is capable of overcoming BST2 restrictions on virus release under certain conditions. ./cache/cord-321564-6950p8i9.txt ./txt/cord-321564-6950p8i9.txt
