Aging blocks the retina's ability to regrow lost neurons, a first-of-its-kind study finds

A new study from the laboratory of Levi Todd, Ph.D., at Upstate Medical University has found that aging significantly limits the ability of support cells in the retina, called glia, to be reprogrammed into new neurons, a finding with important implications for the future of regenerative medicine for age-related neurodegenerative diseases such as Alzheimer's, Parkinson's and glaucoma.
