ABSTRACT
The Tat protein of human immunodeficiency virus (HIV) is essential for viral replication and has extracellular pathogenic activity. We sought to determine whether the anti-Tat antibody response was predictive of disease progression in 144 HIV type 2 (HIV-2)-infected subjects observed longitudinally between 1985 and 2003. Sixty-eight percent of the subjects tested positive for anti-Tat antibodies, with reactivity notably established early after seroconversion and stably maintained over the course of infection. The risk and rate of progression to advanced HIV-2 AIDS was significantly higher in anti-Tat-negative subjects than in anti-Tat-positive subjects, extending the importance of this prognostic marker for HIV-2 AIDS.

    Background: Nef is a 27 KDa HIV-1 accessory protein. It downregulates CD4 from infected cell surface, a mechanism critical for efficient viral replication and pathogenicity. Agents that antagonize the Nef-mediated CD4 downregulation may offer a new class of drug to combat HIV infection and...
