Abstract

Defining adaptive immunity with the complex structures of the human gastrointestinal (GI) tract over life is essential for understanding immune responses to ingested antigens, commensal and pathogenic microorganisms, and dysfunctions in disease. We present here an analysis of lymphocyte localization and T cell subset composition across the human GI tract including mucosal sites (jejunum, ileum, colon), gut-associated lymphoid tissues (isolated lymphoid follicles (ILFs), Peyer's patches (PPs), appendix), and mesenteric lymph nodes (MLNs) from a total of 68 donors spanning eight decades of life. In pediatric donors, ILFs and PP containing naïve T cells and regulatory T cells (Tregs) are prevalent in the jejunum and ileum, respectively; these decline in frequency with age, contrasting stable frequencies of ILFs and T cell subsets in the colon. In the mucosa, tissue resident memory T cells develop during childhood, and persist in high frequencies into advanced ages, while T cell composition changes with age in GALT and MLN. These spatial and temporal features of human intestinal T cell immunity define signatures that can be used to train predictive machine learning algorithms. Our findings demonstrate an anatomic basis for age-associated alterations in immune responses, and establish a quantitative baseline for intestinal immunity to define disease pathologies.

  • Tregs are present throughout the human body and their abundance in circulation and tissues is age dependent.

    “Tregs are present throughout the human body and their abundance in circulation and tissues is age dependent [264, 359].”

    From Guidelines for the use of flow cytometry and cell sorting in immunological studies (third edition) (2021) · cites this paper as [359]

    The Results section, “Localization of Intestinal Tregs in GALT with highest frequencies during childhood” (page not provided), reports that Treg frequency in gut-associated lymphoid tissue and mesenteric lymph nodes is highest in younger donors and declines with age. The paper does not establish that Tregs are present throughout the body or that their abundance in circulation is age dependent; it also reports no significant age-related change at some intestinal sites.

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.
