Researchers at USC and Harvard have developed a new approach to repair cells deep inside the ear — a potential remedy that could restore hearing for millions of elderly people and others who suffer hearing loss.
The lab study demonstrates a novel way for a drug to zero in on damaged nerves and cells inside the ear. It’s a potential remedy for a problem that afflicts two-thirds of people over 70 years and 17 percent of all adults in the United States.
“What’s new here is we figured out how to deliver a drug into the inner ear so it actually stays put and does what it’s supposed to do, and that’s novel,” said Charles E. McKenna, a corresponding author for the study and chemistry professor at USC Dornsife College of Letters, Arts and Sciences. “Inside this part of the ear, there’s fluid constantly flowing that would sweep dissolved drugs away, but our new approach addresses that problem. This is a first for hearing loss and the ear. It’s also important because it may be adaptable for other drugs that need to be applied within the inner ear.”
