Gene therapy can help restore hearing in deaf people

According to the World Health Organization, there are currently over 360 million people with hearing impairments in the world. Hearing aids and cochlear implants (prostheses) help them to hear those around them again. But soon such people can come to the aid of gene therapy.

It should be noted that hearing loss often occurs due to damage to small hairs located in the inner ear. For people with these problems, gene therapy can actually help. To be more precise, scientists propose to treat deafness by injecting patients with special drugs with the Atoh1 gene, which, according to them, promotes the growth of hair cells in the organ of Corti.

The drugs have already been tested in laboratory mice. The research results were impressive - the sound perception of the mice participating in the experiment increased by an average of 20 dB. In the near future, the researchers plan to test their method on humans - 45 volunteers have already been selected for this.
