Evolution of the Human Immunodeficiency Virus Type 1 Envelope during Infection Reveals Molecular Corollaries of Specificity for Coreceptor Utilization and AIDS Pathogenesis

Abstract excerpt

The evolution of human immunodeficiency virus type 1 infection is associated with a shift in the target cell population, driven by variability in coreceptor utilization resulting from diversity in env. To elucidate the potential consequences of these changes for Env-mediated fusion over the course of AIDS, we examined the biological properties of serial viral isolates and determined coreceptor utilization by the...
