Neurovascular Coupling in Hypertension Is Impaired by IL-17A through Oxidative Stress
Bibliographic record
Abstract
Hypertension, a multifactorial chronic inflammatory condition, is an important risk factor for neurovascular and neurodegenerative diseases, including stroke and Alzheimer’s disease. These diseases have been associated with higher concentrations of circulating interleukin (IL)-17A. However, the possible role that IL-17A plays in linking hypertension with neurodegenerative diseases remains to be established. Cerebral blood flow regulation may be the crossroads of these conditions because regulating mechanisms may be altered in hypertension, including neurovascular coupling (NVC), known to participate in the pathogenesis of stroke and Alzheimer’s disease. In the present study, the role of IL-17A on NVC impairment induced by angiotensin (Ang) II in the context of hypertension was examined. Neutralization of IL-17A or specific inhibition of its receptor prevents the NVC impairment (p < 0.05) and cerebral superoxide anion production (p < 0.05) induced by Ang II. Chronic administration of IL-17A impairs NVC (p < 0.05) and increases superoxide anion production. Both effects were prevented with Tempol and NADPH oxidase 2 gene deletion. These findings suggest that IL-17A, through superoxide anion production, is an important mediator of cerebrovascular dysregulation induced by Ang II. This pathway is thus a putative therapeutic target to restore cerebrovascular regulation in hypertension.

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.
