Inflammatory mediators and growth factors in the spinal cord of G93A SOD1 rats
Bibliographic record
Abstract
Amyotrophic lateral sclerosis (ALS) is a devastating motor neuron disease. One mechanism involved in ALS pathology is neuroinflammation. Neuroinflammation is mediated by soluble pro-inflammatory molecules such as cytokines, prostaglandins and nitric oxide. Studies on transgenic mice demonstrated the expression of pro-inflammatory mediators in early stages of murine ALS. Recently a transgenic rat model became available. Since species differences in regard to cytokine expression have been reported in other disease models we set out to validate the neuroinflammatory hypothesis in the ALS-transgenic rat. We investigated the expression of inflammatory mediators and growth factors in the spinal cord by semi-quantitative RT-PCR. We found that several pro-inflammatory mediators are up-regulated at asymptomatic and end-stages, whereas VEGF, a neuroprotective factor was down-regulated.

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.
