SIU Medicine Scientist Receives DOD Grant To Advance Hearing Loss Treatments
SPRINGFIELD - The U.S. Department of Defense (DOD) has awarded a $1.5 million grant to SIU School of Medicine scientist Brandon Cox, PhD, to test compounds that are predicted to stimulate regeneration of cells used for hearing, called hair cells. The process could illuminate a path to restore human hearing. Researchers have discovered that birds, fish and amphibians can regrow these auditory hair cells. The new hair cells form from adjacent supporting cells after damage. Humans are born with roughly 12,000 of these specialized sound-detecting cells within the ear. Hair cell damage is a common cause of hearing loss, affecting about 1.5 billion people worldwide. Once hair cells are killed, it is believed the damage is irreversible and becomes cumulative as we age. Hearing loss is the most common injury that affects men and women serving in the United States military. The damage can result from either intense or prolonged exposure to loud noise or exposure to specific medications. Members
