Researchers at Harvard Medical School may have developed a new drug combination that could help reverse hearing damage that comes from the loss of inner ear hair cells.
According to a paper published in the Proceedings of the National Academy of Sciences, the cocktail of molecules was able to reprogram the genetic pathways in the inner ears of mice to regrow hair cells.
The inner ear hairs amplify vibrations into the brain in order to be detected, but when they are damaged, say from loud noises or music, they cannot be regrown in humans. This then causes hearing loss.
