Neuregulin-1 type I: a hidden power within Schwann cells for triggering peripheral nerve remyelination
Abstract
Physiological interactions and reciprocal signaling between axons and Schwann cells play critical roles in nerve development and survival. Axonally derived neuregulin-1 (NRG-1) type III is an essential modulator of Schwann cells during development, nerve repair, and remyelination. A recent report demonstrates an unexpected regulatory role for Schwann cell-derived NRG-1 type I in Schwann cell plasticity and remyelination after peripheral nerve injury. Specifically expressed in Schwann cells at critical time points after nerve injury, this isoform of NRG-1 emerges as a driving force for regeneration and remyelination programs.
