Noise-induced, drug-related, and age-related disabling hearing loss is a global public health problem that affects approximately 466 million people. While non-mammalian vertebrates have the ability to regenerate sensory hair cells, this capacity is lost in mammals, leading to permanent hearing loss. Current treatments for hearing loss, such as cochlear implants and hearing devices, only provide limited help. Recent studies have shown promising results in regenerating mammalian cochlear hair cells by manipulating molecular pathways or transcription factors.
Noise-induced, drug-related, and age-related disabling hearing loss is a major public health problem and affect approximately 466 million people worldwide. In non-mammalian vertebrates, the death of sensory hair cells (HCs) induces the proliferation and transdifferentiation of adjacent supporting cells into new HCs; however, this capacity is lost in juvenile and adult mammalian cochleae leading to permanent hearing loss. At present, cochlear implants and hearing devices are the only available treatments and can help patients to a certain extent; however, no biological approach or FDA-approved drug is effective to treat disabling hearing loss and restore hearing. Recently, regeneration of mammalian cochlear HCs by modulating molecular pathways or transcription factors has offered some promising results, although the immaturity of the regenerated HCs remains the biggest concern. Furthermore, most of the research done is in neonates and not in adults. This review focuses on critically summarizing the studies done in adult mammalian cochleae and discusses various strategies to elucidate novel transcription factors for better therapeutics.
