Nogo‐A inhibits vascular regeneration in ischemic retinopathy
Bibliographic record
Abstract
Nogo-A is a potent glial-derived inhibitor of axon growth in the injured CNS and acts as a negative regulator of developmental angiogenesis by inhibiting vascular endothelial cell migration. However, its function in pathological angiogenesis has never been studied after ischemic injury in the CNS. Using the mouse model of oxygen-induced retinopathy (OIR) which yields defined zones of retinal ischemia, our goal was to investigate the role of Nogo-A in vascular regeneration. We demonstrate a marked upregulation of the Nogo-A receptor sphingosine 1-phosphate receptor 2 in blood vessels following OIR, while Nogo-A is abundantly expressed in surrounding glial cells. Acute inhibition of Nogo-A with function-blocking antibody 11C7 significantly improved vascular regeneration and consequently prevented pathological pre-retinal angiogenesis. Ultimately, inhibition of Nogo-A led to restoration of retinal function as determined by electrophysiological response of retinal cells to light stimulation. Our data suggest that anti-Nogo-A antibody may protect neuronal cells from ischemic damage by accelerating blood vessel repair in the CNS. Targeting Nogo-A by immunotherapy may improve CNS perfusion after vascular injuries.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
