Japanese scientists have developed a vaccine that can significantly slow down the human aging process.
In a new study, scientists from Japan have for the first time identified a protein called GPNMB, which is expressed in dead cells at a high level. This protein has also been found in high concentrations in patients with atherosclerosis, which is associated with aging.
The researchers tested what happened when GPNMB was removed. The team fed mice a high-fat diet to speed up aging and then genetically eliminated cells that expressed GPNMB. These mice had fewer metabolic disorders and other molecular markers of aging, as well as less pronounced symptoms of atherosclerosis than control rodents.
