Viral cell-to-cell spread: Conventional and non-conventional ways
For instance, cell-to-cell transmission of HIV-1 depends on cell-cell contacts that form by the interaction of Env protein in the donor cell with the CD4 receptor on the target cell; thus neutralizing antibodies against Env protein can block cell-cell contact and cell-to-cell spread (Chen et al., 2007; Jolly et al., 2004; Rudnicka et al., …
