Abstract

Abstract: The human immune system evolved to defend the organism against pathogens, but is clearly less well able to do so in the elderly, resulting in greater morbidity and mortality due to infectious disease in old people, and higher healthcare costs. Many age‐associated immune alterations have been reported over the years, of which probably the changes in T cell immunity, often manifested dramatically as large clonal expansions of cells of limited antigen specificity together with a marked shrinkage of the T cell antigen receptor repertoire, are the most notable. It has recently emerged that the common herpesvirus, cytomegalovirus (CMV), which establishes persistent, life‐long infection, usually asymptomatically, may well be the driving force behind clonal expansions and altered phenotypes and functions of CD8 cells seen in most old people. In those few who are not CMV‐infected, another even more common herpesvirus, the Epstein‐Barr virus, appears to have the same effect. These virus‐driven changes are less marked in “successfully aged” centenarians, but most marked in people whom longitudinal studies have shown to be at higher risk of death, that is, those possessing an “immune risk profile” (IRP) characterized by an inverted CD4:8 ratio (caused by the accumulation primarily of CD8+ CD28− cells). These findings support the hypothesis that persistent herpesviruses, especially CMV, act as chronic antigenic stressors and play a major causative role in immunosenescence and associated mortality.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Classifying these cells as 'senescent' is subject to debate, and is dependent on what constitutes the definition of senescence.

    “Classifying these cells as “senescent” however is subject to debate, and is dependent on what constitutes the definition of senescence (e.g., loss or expression of key cell-surface molecules, functional capacity, such as the ability to proliferate, produce cytokines and kill targets, or telomere length) (Koch et al. 2007; Pawelec 2013).”

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.
