In this study, researchers developed a mathematical model of outer hair cell hair bundles that replicates experimental responses to mechanical stimuli, providing insights into the stimulus-dependent adaptation mechanisms and the functional significance of their three-row stereocilia configuration in mammalian hearing.

February 2012 in “The journal of neuroscience/The Journal of neuroscience” This study observed that Ptprq mutant mice exhibit significant abnormalities in hair bundle structure and vestibular dysfunction, suggesting similar issues may contribute to hearing loss and vestibular problems in humans with PTPRQ mutations.

August 2010 in “Developmental neurobiology” This study suggests that Ptprq in the hair bundles may exist as multiple isoforms that are differentially expressed throughout development and affect the organization of stereocilia in the chick inner ear.
April 2026 in “Proceedings of the National Academy of Sciences” In this study, Tmem30b was identified as a key regulator of outer hair cell structure in mice, and its modulation may offer a therapeutic approach for certain types of hearing loss.
April 2026 in “Frontiers in Cell and Developmental Biology” This literature review suggests that hair cell loss in hearing loss is often secondary to preceding morphological and functional defects in hair cells, indicating that interventions should focus on hearing preservation before significant hair cell loss occurs.
