From model to man: Understanding Tregs' dual role in MASLD
Bibliographic record
Abstract
Background & Aims: Metabolic Dysfunction-associated Steatotic Liver Disease (MASLD) affects around 30% of the world's population and is often associated with metabolic conditions such as obesity, diabetes and hypertension. Approximately 10-20% of metabolic dysfunction-associated steatotic liver disease cases progress to metabolic dysfunction-associated steatohepatitis (MASH), which significantly increases the risk of liver cancer. While intrahepatic immune responses involving CD4+ and CD8+ T cells are potential therapeutic targets, their role in the pathogenesis of MASH is not fully understood. Regulatory T cells (Tregs), whose involvement has been controversial, require further investigation. Methods: -deficient C57BL/6 mice, supplemented with human liver samples. Results: Our results showed that HF-HCD induced glucose intolerance and MASH, independent of adaptive immunity. Surprisingly, HF-HCD increased intrahepatic Treg numbers and the Treg/Teff ratio but did not alleviate the disease; instead, this increase correlated with greater disease severity. With progressing metabolic inflammation, an increased proportion of Tregs also expressed IL-17, which correlated with more severe liver pathology. Conclusions: 17-skewed) cells. These findings highlight the complex role of adaptive immunity in MASH progression and provide potential targets for future immunomodulatory therapies. Impact and implications: T cells markedly amplify hepatocellular injury and fibrosis. By separating initiating (macrophage-driven) from amplifying (adaptive) immune signals, our study refines current pathogenic models and provides hepatologists and immunologists with stage-specific therapeutic targets. For clinicians and trial designers, the data indicate that stabilizing Tregs or selectively dampening pro-inflammatory T-cell subsets could complement metabolic interventions in metabolic dysfunction-associated steatotic liver disease/steatohepatitis, whereas indiscriminate Treg expansion might be counter-productive. Because the conclusions are drawn from a murine model, translation to humans will require validation in patient-derived tissues and non-invasive immune biomarkers.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
