Role of viral regulatory and accessory proteins in HIV-1 replication

Abstract excerpt

Human immunodeficiency virus-1 (HIV-1) is the causative agent of acquired immune deficiency syndrome (AIDS), a disease characterized by CD4+ T lymphocyte depletion. HIV-1 replicates actively in a variety of cells by encoding several regulatory (Tat and Rev) and accessory (Vpr, Vif, Vpu, and Nef) proteins. Accessory proteins, thought initially to be dispensable for infection, have now been shown to be important...
