Assessment of telomere length in HIV-1–specific, CMV/EBV-specific, and bulk CD8+ T cells from different patient populations with HIV-1. (A) Proportion of studied antigen-specific tetramer+ CD8+ T cells in total CD8+ T-cell populations from individuals with chronic progressive, chronic long-term nonprogressive, or acute HIV-1 infection, as determined by flow cytometry. Horizontal bars reflect medians. (B) Telomere length of HIV-1–specific, CMV/EBV-specific, and autologous bulk CD8+ T cells from the corresponding individuals. Horizontal bars reflect means.
