Summary
Nearly 40% of hearing loss is attributable to traumatic noise exposure. This project will test a new idea that cells in the inner ear are damaged and die via noise-induced proteolysis, and investigate whether a similar mechanism operates during age-related hearing loss. It will open new avenues for therapies to preserve hearing where trauma is unavoidable, or has occurred through accident or incident.

Summary
In 2010 a novel genetic mutation was identified that causes progressive hearing loss in humans, however, it was not established why this mutation leads to the disease. We propose that the mutation renders cells of the inner ear more susceptible to death caused by noise trauma. We will investigate this in a mouse model of the human condition. This could lead to the development of therapies that prevent hearing loss.
