Abstract

fetched live from OpenAlex

Abstract Invariant Natural Killer T cells (iNKTs) are pivotal innate T cells that regulate immunity through cytokine secretion. In extra-hepatic autoimmunity, distinct regulatory iNKT cell types (iNKTR) play crucial roles. Recently, we identified a novel liver-specific subset, Maf+LiNKTR1 cells, characterized by its CD4+ TR1-like transcriptional signature. This subset responds to lipid-antigen-presenting nanomedicines, suppressing liver autoimmunity; however, its role under homeostatic conditions, in autoimmunity development, and responsiveness to other iNKT-directed therapies are not known. Using mouse models of Primary Biliary Cholangitis (PBC), here we explored the immunoregulatory role and therapeutic potential of Maf+LiNKTR1 cells. We observed a significant decrease in Maf+LiNKTR1 in PBC, accompanied by increased proinflammatory LiNKT1 subset. Biliary epithelial IL-10 signaling and gut-derived short-chain fatty acids contributed to Maf+LiNKTR1 generation. The reduced Maf+LiNKTR1 frequency correlated with loss of regulatory networks, suggesting a role in maintaining liver tolerance. Importantly, the subset responded to other iNKT-directed drugs, significantly suppressing PBC. Our study extended to the broader regulatory network of Maf+LiNKTR1. Further, it enhances our understanding of Maf+LiNKTR1 in liver health and autoimmunity development, offering potential therapeutic insights for autoimmune and other inflammatory liver conditions.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
