Aging can be slowed down or sped up by activating or deactivating a pathway in a mouse's brain (shown above: hippocampus region of a mouse brain).
For the first time, a brain region has been found that may control aging throughout the whole body, a new study reports.
A signaling pathway in the brain region known as the hypothalamus could speed up or slow down aging in mice. If it applies in humans, the discovery could open up possibilities for slowing age-related diseases and increasing life span.
"There's really not much understanding regarding the mechanism of aging," said senior author Dr. Dongsheng Cai, a molecular pharmacologist at Albert Einstein College of Medicine in New York. [Extending Life: 7 Ways to Live Past 100]
