Phosphatidylserine save-me signals drive functional recovery of severed axons in Caenorhabditis elegans [Neuroscience]

Functional regeneration after axonal injury requires transected axons to regrow and reestablish connection with their original target tissue. The spontaneous regenerative mechanism known as axonal fusion provides a highly efficient means of achieving targeted reconnection, as a regrowing axon is able to recognize and fuse with its own detached axon...
