In a group of studies published May 4, 2014 in the journals Science and Nature Medicine, researchers say old mice who were infused with the blood of spry younger mice showed clear improvements in memory, sensory function, strength and endurance.

Led by Stanford School of Medicine in California, the study introduces the idea that age-related decline is reversible, pointing the way to potential new treatments for Alzheimer’s disease and other dementias.

Researchers say a specific protein, found in the blood of mice and humans, appears to be at the root of this rejuvenation. They say they hope to test the protein’s effect on humans in clinical trials in the next few years.
