Researchers have restored vision in mice after stroke. The results, published in Frontiers in Cell and Developmental Biology, showed that after mice suffered from a stroke, delivery of NeuroD1 restored vision. Using AAV9 vectors to deliver NeuroD1 reprogrammed glial cells in the brain to neurons to restore light sensitivity. This research goes to show the huge benefit of gene therapy, not just to patients suffering from life long and debilitating genetic diseases but also patients who develop conditions during their lifetime.
