Scientists discover a hidden immune signal that helps spinal cords regrow
SMRTR summary
Scientists have found that neutrophils, immune cells once thought to only clean up debris after injury, actually play a key role in spinal cord regeneration. Studying zebrafish, researchers discovered that a molecule called Il-4, released by specific neutrophils, controls inflammation and allows nerve fibers to regrow. This raises hope that a similar approach could one day help improve recovery from spinal cord injuries in humans.
