Vimentin participates in microglia activation and neurotoxicity in cerebral ischemia
Bibliographic record
Abstract
Microglia are the 'immune cells' of the brain and their activation plays a vital role in the pathogenesis of many neurodegenerative diseases. Activated microglia produce high levels of pro-inflammatory factors, such as TNFα, causing neurotoxicity. Here we show that vimentin played a key role in controlling microglia activation and neurotoxicity during cerebral ischemia. Deletion of vimentin expression significantly impaired microglia activation in response to LPS in vitro and transient focal cerebral ischemia in vivo. Reintroduction of the functional vimentin gene back into vimentin knockout microglia restored their response to LPS. More importantly, impairment of microglia activation significantly protected brain from cerebral ischemia-induced neurotoxicity. Collectively, we demonstrate a previously unknown function of vimentin in controlling microglia activation.

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.
