    ..This reveals that Vpu markedly increases the rate of viral replication in vivo. Combining experiments with mathematical modeling, we provide an estimate for the contribution of Vpu to viral replication in humanized mice. ..

    ..These findings suggested that primate lentiviruses have adapted to use CBF-β, an evolutionary stable protein, to counteract APOBEC3 proteins of their hosts after diverging from other lentiviruses. ..

    ..Our findings can be a clue to elucidate the complicated evolutionary processes by which lentiviruses adapt to mammals. ..

    ..We further demonstrate a gain-of-function evolution of SIVcpz in infected humanized mice. Our study reveals that pandemic HIV-1 has emerged through at least two steps: preadaptation and subsequent gain-of-function mutations. ..

    ..The cell type-specific effect of hBST-2 may be critical to elucidate the mechanism of BST-2-dependent suppression of virus release. ..

    ..This review describes the current knowledge of the roles of HIV-1 accessory proteins in viral infection, replication, and pathogenicity in vivo, which are revealed by the studies using humanized mouse models. ..

    ..The experimental-phylogenetic investigation sheds light on the evolutionary history of the domestic cat, which was likely influenced by lentiviral infection. ..
