CMV-driven vectors provoked significantly stronger immune activation than CBA. Serotype comparisons showed AAV9 induced greater immunogenicity, with elevated F4/80+ cells at two weeks (p < .001) and prolonged CD68+ cell elevation through four weeks (p < .001) versus AAV1. AAV9 triggered diffuse inflammation, while AAV1 responses were modiolus-restricted.Conclusions and significance: These findings highlight serotype- and promoter-dependent immunogenicity as key determinants of cochlear inflammation.

Numerous studies have identified mutations in MYO15A in humans, analyzed their presence and co-segregation, and predicted their pathogenicity using software tools. However, few have investigated the pathogenic mechanisms of these mutations using mouse models. In a prior study, we identified the MYO15A c.2482 C > T mutation as a potential causative gene for deafness in a Uygur family from Xinjiang. To further explore the pathogenicity and mechanisms of this mutation, we constructed a mouse model harboring the Myo15a c.2455A > T mutation. This study demonstrates that mice with the Myo15a c.2455A > T spot knock-in exhibit the abnormal hair cell morphology, dysfunction, and hearing loss phenotype observed in humans.Objectives: To investigate the pathogenic mechanism of deafness caused by MYO15A c.2482C > T mutation.Material and methods: To assess the impact of the MYO15A mutation on hair cell morphology and function, mice underwent audiological tests, quantitative real-time PCR, scanning electron microscopy, immunofluorescence, and Western blot analysis.Results: The p.Arg819* mutation located in the N-terminal domain of MYO15A showed marked differences in hair cell morphology and function between homozygous mutant mice and normal controls. Notably, the homozygous mutant mice retained residual hearing up to approximately five weeks of age.Conclusions and significance: Our findings confirm that Myo15a c.2455A > T spot knock-in mice replicate the abnormal hair cell morphology and dysfunction, as well as the hearing loss phenotype. Additionally, our results indicate that the novel c.2482C > T variant in the MYO15A gene can cause inner ear hair cell dysfunction and audiological disorders in this family.","PeriodicalId":6880,"journal":{"name":"Acta Oto-Laryngologica","volume":" ","pages":"363-374"},"PeriodicalIF":1.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
