Memory T cell homeostasis and senescence during aging
Abstract
Human memory T cell pools proliferate and differentiate at varying rates that are determined by the frequency of lifelong antigenic re-encounter with different specific antigens. An important question concerning immunity is whether certain specific pools of memory T cells are driven to exhaustion in elderly subjects, a pertinent point in view of increasing human life expectancy. An emerging consensus is that cytomegalovirus (CMV), a beta-herpesvirus with a prevalence of 60-90% worldwide, is an agent that induces specific T cells to extreme differentiation. The question that begs to be answered is whether this can explain why CMV seropositivity and the presence of highly differentiated CMV-specific T cells are included in a cluster of immune parameters that have been shown recently to predict the early mortality of elderly humans.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
