Functioning of aged brains and muscles in mice made younger
Date:5/4/2014

w should have more widespread effects on brain function. We do think that, at least in principle, there will be a way to reverse some of the cognitive decline that takes place during aging, perhaps even with a single protein. It could be that a molecule like GDF 11, or GDF 11 itself, could" reverse the damage of aging.

"It isn't out of question that GDF11," or a drug developed from it, "might be capable of slowing some of the cognitive defects associated with Alzheimer's Disease, a disorder whose main risk factor is aging itself," Rubin said. It is even possible that this could occur without directly changing the "plaque and tangle burden" that are the pathological hallmarks of Alzheimer's. Thus, a future treatment for this disease might be a combination of a therapeutic that reduces plaques and tangles, such as an antibody directed against the β-amyloid peptide, with a potential cognition enhancer like GDF-11.

Wagers said that the two research groups are in discussions with a venture capital group to obtain funding to "be able to do the additional preclinical work" necessary before moving GDF 11 into human trials.

"I would wager that the results of this work, together with the other work, will translate into a clinical trial and a treatment," said the stem cell biologist. "but of course that's just a wager."
