FAS and HIV-1 infection: Similarly, CD95+ cells were detected at a higher frequency in the HIV-specific CD8+ T cell subset compared to the overall CD8+ subset at 3–6 months (92%, range 28–95 versus 56%, range 8.4–78, respectively; p = 0.027), 7–12 months (83%, range 46–91 versus 47%, range 16–63, respectively; p = 0.010), and 23–24 months (88%, range 79–96 versus 47%, range 34–61, respectively; p = 0.030) post HIV-1 infection.
