The Delayed Post-Injury Administration of Soluble Fas Receptor Attenuates Post-Traumatic Neural Degeneration and Enhances Functional Recovery after Traumatic Cervical Spinal Cord Injury
Bibliographic record
Abstract
Spinal cord injury (SCI) is a devastating condition that currently lacks clinically-relevant and effective neuroprotective therapeutic options. Optimal therapeutic agents for clinical translation should show efficacy in a cervical compression/contusion model using a clinically-relevant post-injury therapeutic time window. To date, few compounds have met that rigorous standard. The objective of this work was to evaluate the efficacy of delayed post-injury administration of soluble Fas receptor (sFasR) via intrathecal catheter following acute cervical SCI in a clinically-relevant contusion/compression model. Female Wistar rats were given a C7-T1 moderately severe clip compression injury, followed by either 8-h or 24-h delayed treatment initiation. Long-term neurobehavioral analysis of motor recovery and neuropathic pain development was undertaken. The extent of oligodendrocyte and neuron survival was assessed in peri-lesional cord sections 8 weeks post-SCI. This was complemented by an evaluation of the level of tissue preservation at and adjacent to the site of injury. In animals treated with sFasR delayed 8 h post-injury, significant behavioral effects were observed, coinciding with enhanced cell survival, peri-lesional tissue sparing, and enhanced integrity of descending fiber tracts compared to control treatments. Animals treated with sFasR delayed by 24 h showed more modest improvements in behavioral recovery, and had consistent improvements in cell survival and tissue preservation. This work has shown for the first time that the Fas-mediated apoptotic pathway can be therapeutically targeted in a clinically-relevant time window post-SCI.

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.
