A stress hormone may help the brain repair itself
✦AI Summary
Scientists have discovered that oligodendrocyte progenitor cells multiply around brain injuries and help repair damaged myelin. This process is supported by a stress hormone, offering new insights into brain recovery mechanisms.
When laboratory mice experience brain damage, e.g., from an injection, Jan Deussing repeatedly notices the same response. A particular group of cells appears and becomes active around the damaged area. Although Deussing, a research group leader and experienced neurobiologist, had observed the phenomenon many times, he did not know exactly what type of cells were involved.
