Different immunological requirements for protection against acute versus persistent Friend retrovirus infections.

abstract：:Herpes simplex virus 1 glycoprotein B (gB) is one of 10 glycoproteins in the virion envelope and in the membranes of infected cells. It is required for infection of cells in culture and functions in penetration of the cell by fusing the virion envelope with the plasma membrane. In studies to map the functional domains...

abstract：:The HIV-1 protein Vpr enhances macrophage infection, triggers G2 cell cycle arrest, and targets cells for NK-cell killing. Vpr acts through the CRL4(DCAF1) ubiquitin ligase complex to cause G2 arrest and trigger expression of NK ligands. Corresponding ubiquitination targets have not been identified. UNG2 and SMUG1 are...
