Stanford neuroscientist Tony Wyss-Coray, PhD, has spent 20 years discovering and investigating various molecules with neuroprotective and neurodegenerative properties. These molecules are found in or on different cell types in the brain and on the blood vessels abutting it or floating in the blood and the cerebrospinal fluid that bathes it. As we age they become increasingly important.
Wyss-Coray and his colleagues have discovered substances in blood that can accelerate or slow down the brain-aging clock. They’ve identified proteins on blood-vessel surfaces through which some of these molecules can act on the brain, despite the existence of the blood-brain barrier. He’s even shown that older mice look and act younger after receiving young mouse cerebrospinal fluid.
