Survival of auditory hair cells

Cell Tissue Res. 2015 Jul;361(1):59-63. doi: 10.1007/s00441-015-2152-5. Epub 2015 Mar 7.


The inability of mammals to regenerate auditory hair cells creates a pressing need to understand the means of enhancing hair cell survival following insult or injury. Hair cells are easily damaged by noise exposure, by ototoxic medications and as a consequence of aging processes, all of which lead to progressive and permanent hearing impairment as hair cells are lost. Significant efforts have been invested in designing strategies to prevent this damage from occurring since permanent hearing loss has a profound impact on communication and quality of life for patients. In this mini-review, we discuss recent progress in the use of antioxidants, anti-inflammatories and apoptosis inhibitors to enhance hair cell survival. We conclude by clarifying the distinction between protection and rescue strategies and by highlighting important areas of future research.
