CRH Hormone Controls Brain Repair Timing | Science News
Brain repair just got a breakthrough: scientists have identified oligodendrocyte progenitor cells (OPCs) as the key players in rebuilding myelin after injury or disease. These cells multiply rapidly, mature, and restore insulation for nerve fibers—critical for brain communication. A surprising twist? The stress hormone CRH, released within hours of damage, acts as a timer, ensuring OPCs mature at the right moment. Without this control, repair falters. Even more intriguing, CRH appears to shape myelin formation during normal brain development, with missing receptors leading to thicker but…
