Does human papillomavirus found in sperm head of young adult males affect the progressive motility?
This is the first report estimating the percentage of HPV-positive sperm in infected subjects and the association between HPV infection and sperm motility.
Our data explain why the effect of the S52A mutation in Vpu on virus release is cell-type dependent and suggest that a reduced ability of Vpu to counteract tetherin impairs HIV-1 replication in macrophages, but not in tissue CD4+ T cells.
