摘要
Background. Human immunodeficiency virus ( HIV) infection and disease are accompanied by decreases in the absolute number and function of V(gamma)2V delta 2 T cells, suggesting that this subset of cells may play an important role in controlling disease. We performed a cross-sectional study involving HIV-infected former blood donors and assessed the association between V(gamma)2V delta 2 T cells and markers of disease progression. Methods. Changes in V(gamma)2V delta 2 T cell count and function were compared between HIV-infected individuals and healthy blood donors using the Mann-Whitney U test. The relationships between Vg2Vd2 T cell count, plasma viral load, and CD4 T cell count were analyzed using the Spearman correlation. Results. We found significant positive correlations between CD4 T cell count and both total Vg2Vd2 T cell count () and functional ( isopentenyl pyrophosphate-responsive) V(gamma)2V delta 2 T cell count (P < .001). We found significant reverse correlations between viral load and both total V(gamma)2V delta 2 T cell count (P < .05) and functional V(gamma)2V delta 2 T cell count (P < .05). Conclusions. The association of V(gamma)2V delta 2 T cells with disease progression in 146 HIV-infected participants supports the view that intact V(gamma)2V delta 2 T cell populations are important for controlling HIV disease.
