abstract：:Type 1 human immunodeficiency viruses encoding mutated nef reading frames are 10- to 30-fold less infectious than are isogenic viruses in which the nef gene is intact. This defect in infectivity causes nef-negative viruses to grow at an attenuated rate in vitro. To investigate the mechanism of Nef-mediated enhancement...
