Telomeres and immune competency

Abstract

Telomeres are essential for the integrity of chromosomes and for cellular replication. Attrition of telomeres occurs during DNA replication owing to the inability of conventional DNA polymerase to replicate chromosomal termini and the insufficient compensation for telomere loss by telomerase, an enzyme that synthesizes telomeric DNA. A number of genetic defects have been described in humans and in animal models that cause accelerated telomere attrition, in turn leading to severe phenotypes of hematopoietic and other proliferating cells. Telomere length, most frequently measured as an average value in heterogeneous peripheral blood leukocyte populations in humans, has been associated with a wide range of health conditions and diseases of immune and non-immune cells. Here, I review recent studies of telomere length dynamics with particular relevance to immune function.

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.
