Healthy prions protect the membranes of nerve fibers

When the myelin sheaths of nerve fibers wear out, an enzyme system is triggered that destroys the prion protein. Its fragments enter the Schwann cells, giving them a signal to start restoring myelin.

"Nanoshiki" for cleaning vessels

Similar to dish brushes (or, rather, burdock heads), nanoparticles clean blood vessels from atherosclerotic plaques not mechanically, but due to the ability to attach to the walls of arteries with the help of protein "spikes" and slowly release drugs.
