Demonstrates improved locomotor recovery in spinal cord injuries of varying severity, suggesting new therapeutic avenues.

This research investigates how transneuronal delivery of cytokines can aid recovery after spinal cord injury of varying severities.
Delivered AAV2-hIL-6 cytokine via intracortical injection
Evaluated locomotor function after mild, moderate, and severe contusions
Assessed neuronal connectivity and axon growth in lumbar cord
Conducted serotonergic neuron ablation to determine their role
AAV2-hIL-6 treatment significantly improved locomotor function compared to controls
Increased number and length of descending serotonergic axons in the lumbar cord
No significant effect on lesion size or neuronal loss due to AAV2-hIL-6 treatment
Corticospinal tract regeneration did not correlate with recovery, indicating alternative recovery pathways

Leibinger et al. (2026) studied this question.
