Prevention and/or treatment of hearing loss or impairment

The present invention relates to the use of gasdermin, in particular of gasdermin A, gasdermin B, gasdermin C, gasdermin D, DFNA5 or DFNB59 (or pejvakin), and more particularly pejvakin for modulating cellular redox homeostasis. A particularly preferred use of gasdermin, in particular of gasdermin A, gasdermin B, gasdermin C, gasdermin D, DFNA5 or DFNB59 (or pejvakin), and more particularly pejvakin in the context of the present invention is as an antioxidant. The present invention also concerns a virally-mediated gene therapy for restoring genetically-impaired auditory and vestibular functions in subjects suffering from an Usher syndrome. More precisely, this gene therapy takes advantage of an AAV2/8 vector expressing at least one USH1 gene product, preferably SANS.
