Abstract

Coeliac disease is a common small bowel enteropathy arising in genetically predisposed individuals and caused by ingestion of gluten in the diet. Great advances have been made in understanding the role of the adaptive immune system in response to gluten peptides. Despite detailed knowledge of these adaptive immune mechanisms, the complete series of pathogenic events responsible for development of the tissue lesion remains less certain. This review contributes to the field by discussing additional mechanisms which may also contribute to pathogenesis. These include the production of cytokines such as interleukin-15 by intestinal epithelial cells and local antigen presenting cells as a pivotal event in the disease process. A subset of unconventional T cells called gamma/delta T cells are also persistently expanded in the coeliac disease (CD) small intestinal epithelium and recent analysis has shown that these cells contribute to pathogenic inflammation. Other unconventional T cell subsets may play a local immunoregulatory role and require further study. It has also been suggested that, in addition to activation of pathogenic T helper cells by gluten peptides, other peptides may directly interact with the intestinal mucosa, further contributing to the disease process. We also discuss how myofibroblasts, a major source of tissue transglutaminase and metalloproteases, may play a key role in intestinal tissue remodeling. Contribution of each of these factors to pathogenesis is discussed to enhance our view of this complex disorder and to contribute to a wider understanding of chronic immune-mediated disease.

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

  • The growth of dermal γδ T cells preferentially requires IL-7, whereas IL-15 is mandatory for the generation of γδ TCR-expressing intra-epithelial lymphocytes (IELs).

    “The growth of dermal γδ T cells preferentially requires IL-7, whereas IL-15 is mandatory for the generation of γδ TCR-expressing intra-epithelial lymphocytes (IELs) (13).”

    From Comparing Mouse and Human Tissue-Resident γδ T Cells (2022) · cites this paper as [13]

    The section “A Role for Conventional and Unconventional Lymphocytes?” discusses γδ IELs and links IL-15 to activation and expansion of cytolytic CD8 IELs, but it does not state that IL-15 is mandatory for generating γδ TCR-expressing IELs. Searches for dermal γδ T-cell growth and IL-7 also found no passage addressing the claimed requirement. (LLM, conf=0.70)

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.
