The human immunodeficiency virus type 1 vpr gene prevents cell proliferation during chronic infection.

Abstract excerpt

Human immunodeficiency virus type 1 (HIV-1) is a retrovirus that can cause extensive cytopathicity in T cells. However, long-term productive infection of T-cell lines has been described. Here we show that although Vpr has no effect on the initial cytopathic effect of HIV-1, viruses that contain an intact vpr gene are unable to establish a chronic infection of T cells. However, virus with a mutated vpr gene can...
