Primary B-cell infection with a deltaBALF4 Epstein-Barr virus comes to a halt in the endosomal compartment yet still elicits a potent CD4-positive cytotoxic T-cell response.

Abstract excerpt

Epstein-Barr virus (EBV) infection is mediated by several viral envelope glycoproteins. We have assessed gp110's functions during the virus life cycle using a mutant that lacks BALF4 (DeltaBALF4). Exposure of various cell lines and primary cell samples of epithelial or lymphoid lineages to the DeltaBALF4 mutant failed to establish stable infections. The DeltaBALF4 virus, however, did not differ from wild-type EBV...
