| Outline of Final Research Achievements |
Sensorineural hearing loss due to the dysfunction in the inner ear is intractable. Both clinical and experimental evidences, for instance autoreactive antibody or target antigens, suggest autoimmunity may result in the deafness. We have developed a transgenic mouse model that recapitulate the disruption of tolerance to the inner ear hair cells by using HA-antigen overexpression systems. Data demonstrated that the CD4 positive T-cell mediated autoimmunity to hair cells resulted in cochlear hearing loss with vestibuler dysfunction. Further analyses will be examined for finding therapeutic targets.
