Abstract:
Telomere measurement, envisioned as a novel approach to elucidate T-cell dynamics in HIV disease, failed to reveal any consistent pattern in CD4+ T cells. By contrast, significant telomere shortening, as well as other hallmarks suggestive of replicative senescence, was observed within the CD8+ T-cell subset. Telomere studies have thus provided unanticipated insight into a novel facet of memory CD8+ T lymphocyte dynamics that may explain the exhaustion of the protective antiviral immune response. Strategies aimed at manipulating replicative senescence, therefore, offer unique approaches to immune reconstitution.
