Significant oligodendrocyte progenitor and microglial cell death is a feature of remyelination following toxin-induced experimental demyelination
Bibliographic record
Abstract
The extent to which glial cell turnover features in successful remyelination is unclear. In this study, the rat caudal cerebellar peduncle-ethidium bromide lesion model was used to profile oligodendroglial and microglial/macrophage cell death and proliferation dynamics over the course of repair. Lesioned and control tissue was co-labelled with antibody markers for cell identity, proliferation, and apoptosis (TUNEL assay), then imaged at full thickness using confocal microscopy and quantified using custom CellProfiler pipelines. Early remyelination time points were marked by an increased density of total proliferating cells, including oligodendrocyte progenitor cells. Late remyelination time points featured increased TUNEL+ oligodendrocyte progenitor cells: however, most TUNEL+ cells within remyelinating lesions were Iba1+ microglia/macrophages. These results indicate that repairing lesions are characterized by a high degree of glial cell death and suggest that monitoring cell death-related by-products might have clinical value in the setting of remyelination.

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.
