Abstract

In this work, we find that CD8 + T cells expressing inhibitory killer cell immunoglobulin-like receptors (KIRs) are the human equivalent of Ly49 + CD8 + regulatory T cells in mice and are increased in the blood and inflamed tissues of patients with a variety of autoimmune diseases. Moreover, these CD8 + T cells efficiently eliminated pathogenic gliadin-specific CD4 + T cells from the leukocytes of celiac disease patients in vitro. We also find elevated levels of KIR + CD8 + T cells, but not CD4 + regulatory T cells, in COVID-19 patients, correlating with disease severity and vasculitis. Selective ablation of Ly49 + CD8 + T cells in virus-infected mice led to autoimmunity after infection. Our results indicate that in both species, these regulatory CD8 + T cells act specifically to suppress pathogenic T cells in autoimmune and infectious diseases.

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.
