Abstract

fetched live from OpenAlex

Abstract The role of IL-17 in transplant vasculopathy (TV), which is a leading reflection of chronic allograft rejection, remains poorly defined. The pathogenesis of TV involves luminal narrowing of allograft arteries caused by immune-driven thickening of the intima as well as insufficient compensatory vasodilation or remodeling. The vasodilatory process involves reduced expression and/or activity of the nitric oxide-producing enzyme eNOS by the endothelium. We examined the expression of IL-17 by immunohistochemistry in formalin-fixed, paraffin-embedded human specimens of TV (n=8). IL-17 was expressed by infiltrating leukocytes in the intima of arteries with TV and the majority of IL-17-positive cells were T cells (67.2 ± 11.0% of IL-17A-positive cells were also CD3-positive). Unexpectedly, the number of IL-17-positive cells (when normalized to total T cells) was inversely correlated with the amount of luminal narrowing (Pearson’s r = -0.709, p<0.05), but was not correlated with the intima/media ratio (r = 0.069, p = NS). Because our findings suggest that IL-17 may be involved in compensatory vasodilation, the effect of IL-17 on eNOS expression was examined. IL-17 dose-dependently increased eNOS protein expression in cultured endothelial cells, as determined by Western blotting. These findings suggest that IL-17 may limit luminal narrowing in arteries with TV by contributing to vasodilation through induction of eNOS expression in the endothelium.

Not 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.
