Drugs may some day in the future cure or reduce noise-induced hearing loss. A study in mice conducted by researchers from Harvard Medical School in the US has managed to restore hearing in mice that have been deafened by loud noise.
The mice were injected with a drug (LY411575) in the ear. The mice with damaged hearing were able to grow new hair cells in the inner ear and these new hair cells partially restored their hearing.
Lead researcher Dr. Albert Edge from Harvard Medical School said â€œWe have shown that hair cells can be regenerated from the surrounding cells in the cohleaâ€.
Gene against Usher's syndrome
Researchers from Rosalind Franklin University of Medicine and Science in Chicago in the US have been able to restore hearing in profoundly deaf mice. They focused on a gene called USH1C that is associated with the â€œType 1â€ form of Usherâ€™s Syndrome.
Usher's Syndrome is a disease that affects both hearing and sight. Around one-in-7,000 babies are born with Usherâ€™s Syndrome.
Specialist in neurodegenerative diseases, Dr. Henry Paulson from University in Michigan in the US, finds the results from Rosalind Franklin University very promising. But he also said:
â€œCuring a mouse is quite different from curing a human.â€
