CRHR1 loss speeds OPC growth but weakens myelin repair

Summary

Story summary

Jan Deussing and Clemens Ries found oligodendrocyte precursor cells (OPCs) release corticotropin-releasing hormone (CRH) hours after a brain injury, stopping after three days.
One-third of nearby OPCs activate CRH while CRH receptor 1 on OPCs transduces the signal to time their maturation.
Mice lacking CRHR1 proliferate OPCs faster yet generate fewer mature oligodendrocytes, weakening myelin repair and prompting Deussing to suggest the OPC-CRH system may influence stress-related disorders such as depression.
