Abstract

Understanding how aging impacts the function of memory CD4 T cells is critical for designing effective vaccines. Our studies show that immunological memory generated during youth functions well into old age, whereas that generated later in life functions poorly. This is the result of declines in the function of naive CD4 T cells from aged individuals and contributes to reduced efficacy of vaccines in the elderly. To begin to identify the cause of this defect, we examined the function of memory T cells generated from bone marrow precursor cells (BMPC) from young or aged mice in young hosts. In two different models, memory cells derived from young and aged BMPC exhibit good ex vivo and in vivo function. Importantly, memory CD4 T cells generated from aged BMPC exhibit potent cognate helper function for humoral responses, which are critical for effective immunization. These results indicate that there are no apparent age-related intrinsic defects in BMPC with regards to generation of functional memory T cells.

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.
