The death of neurons, whether in the brain or the eye, can result in a number of human neurodegenerative disorders, from blindness to Parkinson’s disease. Current treatments for these disorders can only slow the progression of the illness, because once a neuron dies, it cannot be replaced.
Now, a team of researchers from the University of Notre Dame, Johns Hopkins University, Ohio State University and the University of Florida has identified networks of genes that regulate the process responsible for determining whether neurons will regenerate in certain animals, such as zebrafish.
“This study is proof of principle, showing that it is possible to regenerate retinal neurons. We now believe the process for regenerating neurons in the brain will be similar,” said David Hyde, professor in the Department of Biological Sciences at Notre Dame and co-author on the study.
