title: Application of new biological approaches to stimulate sensory repair and protection.
abstract: The inner ear governs hearing and balance via six sense organs, each composed of a few thousand mechanosensory hair cells. Most inner ear disorders involve irreversible loss of hair cells and their associated nerves. They are a function of age, genetic abnormalities and environmental factors such as noise and the use of ototoxic drugs. The genetics and cell biology of the inner ear have revealed some key molecular mechanisms of development and sensory degeneration that raise hopes for new therapeutic approaches to the regeneration of sensory function. This review highlights these advances and the approaches that might be taken to effect protection and repair. It concludes with the suggestion that we can expect tangible, practical progress towards the clinic over the next 5-10 years and that, to provide the training and skills required to take full advantage of emerging technologies, we should forge much closer links between specialist clinicians and basic scientists.
