HIV-1 propagation is highly dependent on basal levels of the restriction factor BST2

B Olety, P Peters, Y Wu, Y Usami, H Göttlinger - Science Advances, 2021 - science.org
BST2 is an interferon-inducible antiviral host protein antagonized by HIV-1 Vpu that entraps
nascent HIV-1 virions on the cell surface. Unexpectedly, we find that HIV-1 lacking Nef can …
