The GDF11 protein has another joy to researchers. According to two articles published in the online edition of Science not only gets the heart cells in mice rejuvenated, but also improves their intellectual.  Specifically, researchers at Harvard University found that injecting the protein in mice with an age equivalent to 70 human years, resulted in recovering capabilities of smell, which had lost with aging. The finding has a very interesting read, since humans also have this protein.

Doug Melton, co-director of the Center for Stem Cell Therapies and Regenerative Medicine at Harvard, said he “could not remember a more exciting finding. This should give us hope for a healthier future. We all wondered why we were mentally stronger and more agile when we were young, and these two items suggest a possible answer: the highest levels of GDF11 protein that the young have. There is little doubt that, at least in animals, GDF11 has an incredible ability to restore the functions of the brain and muscles that are lost with aging. “

The assays are, in this case, noteworthy. In each, the protein is simply injected into the mice. In others, however, who used a more complex method: circulatory systems were joined two copies, one young and one old, so that the blood came naturally to the animal that had lower concentration. In both cases the results were similar. This system, although cumbersome, has the advantage of showing the natural function of the protein, molecules that can not be given orally because digestive enzymes degrade them.
