Abstract

Tissue-resident memory T cells (TRM) represent a subset of antigen-experienced T cells that are constantly retained in a given tissue with limited trafficking through the circulation. These cells are characterized by expression of molecules enabling their tissue anchoring and downregulation of molecules promoting tissue egress. They reside at sites of previous antigen encounter and their number increases with age. TRM have been shown to provide rapid and efficient protection against tissue reinfection and TRM density correlates with efficient antitumor responses. Intriguingly, the density of CD8 TRM is increased in the central nervous system (CNS) of patients with neuroinflammatory diseases such as multiple sclerosis, or suffering from neurodegenerative diseases. In this review, we discuss current knowledge regarding the diversity of CNS-resident CD8 T cells and their role in CNS autoimmunity. Given their likely contribution to the protracted course of several inflammatory diseases of the CNS, their therapeutic targeting becomes an important challenge.

  • In organs other than the heart, TRM cells have been incriminated as key drivers of autoimmune diseases including psoriasis, vitiligo, type 1 diabetes, idiopathic arthritis, Alzheimer disease, and multiple sclerosis.

    “Moreover, in other organs than the heart, T RM cells have been incriminated as key drivers of autoimmune diseases including psoriasis, vitiligo, type 1 diabetes, idiopathic arthritis, Alzheimer disease, and multiple sclerosis. 294,302-310”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [308]

    The section on chronic CNS inflammatory disease reports TRM cells in multiple sclerosis and Alzheimer disease and describes ways they may contribute to CNS damage. It does not establish them as key drivers of either disease, and it describes Alzheimer disease as neurodegenerative rather than autoimmune. The passages do not address psoriasis, vitiligo, type 1 diabetes, or idiopathic arthritis. (LLM, conf=0.88)

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.
