Exercise protects the brain, and now UCSF researchers may have discovered how: An exercise-induced protein appears to strengthen the blood-brain barrier, slowing decline. “We’re uncovering biology that Alzheimer’s research has largely overlooked,” Saul Villeda says. https://ucsfh.org/4aAJ9OQ

Scientists Find a Mechanism for How Exercise Protects the Brain

A UCSF team finds a liver protein, released with exercise, that improves memory in aging and Alzheimer’s disease by repairing the brain’s blood vessels. It's the missing link between exercise and brai...
