Here's Today's Feel-Good Story:
It has recently been discovered that exercise could prevent Alzheimer's disease which could lead to new treatments.
Alzheimer's is currently an incurable condition, but a hormone called irisin released during a work-out is associated with the plaques and tangles in the brain thought to cause the disease.
“First, we found that irisin treatment led to a remarkable reduction of amyloid beta pathology,” said Dr. Se Hoon Choi. “Second, we showed this effect of irisin was attributable to increased neprilysin activity owing to increased levels of neprilysin secreted from cells in the brain called astrocytes.”
