Local Delivery of Neurotrophin-3 and Anti-NogoA Promotes Repair After Spinal Cord Injury
Bibliographic record
Abstract
Tissue and functional repair after spinal cord injury (SCI) continue to elude researchers. Neurotrophin-3 (NT-3) and anti-NogoA have been shown to promote axonal regeneration in animal models of SCI; however, localized and sustained delivery to the central nervous system (CNS) remains a critical challenge for these and other macromolecular therapeutics. An injectable drug delivery system (DDS) has previously been developed, which can provide safe local delivery to the spinal cord. This DDS, composed of poly(lactic-co-glycolic acid) (PLGA) nanoparticles (nps) dispersed in a hyaluronan methylcellulose hydrogel, was adapted for the tunable bioactive delivery of NT-3 and anti-NogoA. Furthermore, the combined delivery of NT-3 and anti-NogoA from the DDS in an impact/compression model of SCI increases axon density and improves locomotor function. The benefits of this np/hydrogel DDS observed for NT-3 and anti-NogoA demonstrate the utility of the DDS as a local delivery strategy for protein therapeutics to the CNS.

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.
