In transected nerves, distal repair Schwann cells are required at the injury site to direct and accelerate axonal regrowth

The paper shows that distal Schwann cells at the injury site are essential for guiding and accelerating axonal regrowth after nerve transection in larval zebrafish.

Unmyelinated neurons use Neuregulin signals to promote myelination of neighboring neurons in the CNS

The paper identifies nrg1 type II as a regulator of myelination in zebrafish spinal cord neurons, showing unmyelinated neurons signal to myelinate circuit partners.
