Alterations in the hemagglutinin associated with adaptation of influenza B virus to growth in eggs.

abstract：:Virus genomes are condensed and packaged inside stable proteinaceous capsids that serve to protect them during transit from one cell or host organism, to the next. During virus entry, capsid shells are primed and disassembled in a complex, tightly-regulated, multi-step process termed uncoating. Here we compare the unc...

abstract：:While the C-terminal domain of HIV-1 Vpu is critical for CD4 degradation, the transmembrane domain (TM) mediates ion channel activity, enhances virus release and is essential for counteracting CD317/Bst-2/Tetherin. Here we analyzed whether the ion channel activity of Vpu is required to antagonize CD317-mediated restri...
