Humanin fights Alzheimer's and insulin insensitivity

Cellular Protein Yields Clues to Diabetes, Alzheimer's
Animal tests suggest humanin could have therapeutic benefits : HealthDay

WEDNESDAY, July 22 (HealthDay News) -- New information about a cellular protein might help in efforts to develop drug treatments for diabetes and Alzheimer's disease, researchers say.

In tests on rats, they found that humanin, which may prevent nerve cells from dying, also helps improve insulin action and lower blood glucose levels.

"This new role of humanin in glucose metabolism, in addition to its role in Alzheimer's disease, is very intriguing since scientists have long proposed a link between type 2 diabetes and Alzheimer's disease," Dr. Nir Barzilai, a professor and director of the Institute for Aging Research at the Albert Einstein College of Medicine in New York City, said in a news release from the college.

"Humanin could turn out to be a therapeutic option for two common debilitating diseases that affect millions of people, Barzilai said. "Additionally, humanin may help treat other age-related diseases."

Of course they want to make a drug to mimic humanin. I'm more curious as to the link between insulin resistance and Alzheimer's. This study links the two, but does one cause the other, or does a third factor cause both? If humanin is protective, how can we naturally increase the supply of it in our bodies?

Here is that third factor that you speculate. This article may turn diabetes and AD research upside down?
