24 6 Full Breakdown

Summary

Story summary

The Retsat genetic mutation found in yaks is linked to high-altitude survival and may protect and rebuild myelin.
In mice carrying the Retsat mutation, researchers observed improved learning and memory under low-oxygen conditions.
The mutation increases ATDR levels, a compound that supports myelin-producing cells.
These findings suggest a potential treatment for multiple sclerosis using naturally occurring molecules rather than foreign drugs.
