项目摘要
This subproject is one of many research subprojects utilizing the resources
provided by a Center grant funded by NIH/NCRR. Primary support for the subproject
and the subproject's principal investigator may have been provided by other sources,
including other NIH sources. The Total Cost listed for the subproject likely
represents the estimated amount of Center infrastructure utilized by the subproject,
not direct funding provided by the NCRR grant to the subproject or subproject staff.
X-linked retinoschisis (XLRS) is an inherited form of retinal degeneration affecting young males. It is caused by mutations in a gene (retinoschisin or RS1) that is required for normal retinal function. Patients present with poor vision in infancy or at school age. Visual acuity usually worsens during the teenage years and then stabilizes until complicated by vitreous hemorrhage or retinal detachment during adulthood. In a previous study in a rodent animal model of XLRS, treatment with an AAV-RS1 gene therapy vector resulted in progressive and long-term improvement in retinal function and prevention of retinal cell degeneration. This project is testing the safety and biodistribution of AAV-RS1 vector, injected either subretinally or intravitreally in nonhuman primates, as a critical final step prior to a planned human clinical trial of this potentially sight-saving new therapy. Results indicate that both routes of delivery transduced RS1 to photoreceptors and resulted in expression of the secreted retinoschisin protein.

X连锁视网膜劈裂症(XLRS)是一种影响年轻男性的遗传性视网膜变性。 它是由正常视网膜功能所需的基因(retinoschisin或RS 1)突变引起的。 患者在婴儿期或学龄期视力差。 视力通常在青少年时期下降,然后稳定,直到成年时并发玻璃体出血或视网膜脱离。 在XLRS啮齿动物模型的先前研究中,用AAV-RS 1基因治疗载体治疗导致视网膜功能的进行性和长期改善以及视网膜细胞变性的预防。该项目正在测试AAV-RS 1载体的安全性和生物分布,在非人灵长类动物中视网膜下或玻璃体内注射,作为计划的人类临床试验之前的关键最后一步。 结果表明,这两种途径的交付转导RS 1的感光细胞,并导致分泌的retinoschisin蛋白的表达。
