Research ArticleOpen accessIn the abstractCo-expression of Apoptosis-Related Molecules on Activated CD8+ CD38+ T-cells is Associated with HIV-1 Disease ProgressionJosé W. Rodríguez, Luis A. Rodríguez, Griselle Font et al.CD8+ T cells play a major role in controlling HIV-1 infection through the release of soluble lytic and non-lytic antiviral factors. Their decrease or defective function contributes to the HIV-1 disease progression. HIV-1 disease progression has been associated with a remarkable increase of CD38 expression on CD8+ T-cells. It has been also documented that a significant distribution of HIV-specific CD8+T-cells … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,016 accessesView PDFCite
