Abstract

Throughout life, T cells coordinate multiple aspects of adaptive immunity, including responses to pathogens, allergens, and tumors. In mouse models, the role of T cells is studied in the context of a specific type of pathogen, antigen, or disease condition over a limited time frame, whereas in humans, T cells control multiple insults simultaneously throughout the body and maintain immune homeostasis over decades. In this review, we discuss how human T cells develop and provide essential immune protection at different life stages and highlight tissue localization and subset delineation as key determinants of the T cell functional role in immune responses. We also discuss how anatomic compartments undergo distinct age-associated changes in T cell subset composition and function over a lifetime. It is important to consider age and tissue influences on human T cells when developing targeted strategies to modulate T cell-mediated immunity in vaccines and immunotherapies.

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

  • Younger patients may be more capable of mounting the interferon-driven, anti-viral innate response critical to GTAU and developing robust adaptive immunity compared to adults and the elderly.

    “Younger patients may be more capable of mounting the interferondriven, anti-viral innate response critical to GTAU and developing robust adaptive immunity compared to adults and the elderly (Kumar et al., 2018; Yoshida et al., 2022).”

    From Gene Therapy-Associated Uveitis (GTAU): Understanding and mitigating the adverse immune response in retinal gene therapy (2025) · cites this paper as Kumar et al., 2018

    The Introduction (page not provided) says naïve T cells protect against pathogens in early life and that T-cell functionality declines in later life, supporting an age-related difference in adaptive immunity. It does not establish that younger patients mount stronger adaptive responses than adults, or address an interferon-driven innate response or GTAU. (LLM, conf=0.85)

  • Trm do not express other putative activation markers, such as CD25, CD137, CD38, or HLA-DR.

    “Trm do not express other putative activation markers, such as CD25, CD137, CD38, or HLA-DR [244, 253, 258, 264].”

    From Guidelines for the use of flow cytometry and cell sorting in immunological studies (third edition) (2021) · cites this paper as [264]

    The section “Tissue resident memory T (Trm) cells” says that CD69+ memory T cells in human tissues do not exhibit activation features such as HLA-DR, CD38, or CD25 expression. It does not address CD137, so the full list of markers attributed to this source is not supported. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • 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].”

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.
