Angelica sinensis may provide protection against human immunodeficiency virus infection

Increased oxidative stress and disturbed glutathione redox system play an important role in the pathogenesis of human immunodeficiency virus (HIV) infection. Depletion in intracellular levels of reduced glutathione (GSH) contributes to an increment in tumor necrosis factor α (TNF-α)-stimulated-HIV-1-transcription, activation of HIV-1-replication, sensitivity to TNF-α-induced cell death, and impairment of CD4+ cell function and survival. Therefore, several studies have investigated the effect of GSH-enhancer agents such as N-acetyl cystein in the treatment of patients with HIV infection. With regard to the beneficial effects of Angelica sinensis, a Chinese medicinal herb, on GSH redox system and the pathogenic role of GSH depletion in HIV infection and the immunomodulator effects of active ingredients of this herb, we postulated that Angelica sinensis may be of value in the treatment of HIV-infected patients.
