Humanin peptide linked to neuronal cell survival and regulation of glucose metabolism

Recent studies have shown that the mitochondrial peptide Humanin (HN) protects against neuronal cell death such as happens in Alzheimer's disease. Now, in a study presented April 22 at Experimental Biology 2009 in New Orleans, Dr. Nir Barzilai reports that a small infusion of HN is the most potent regulator of insulin metabolism that his research team has ever seen, significantly improving overall insulin sensitivity and sharply decreasing the glucose levels of diabetic rats.
