中文摘要
我们利用基因组编辑技术在人类和小鼠基因组中的 DNAJC6 基因中引入突变,这些突变与家族性早发性复杂帕金森病 (PD) 相关。由于编码的蛋白质辅助蛋白在神经元中表达,因此我们专注于展示突变如何影响行为。随着年龄的增长,小鼠表现出微妙但重要的运动表型。然而,到目前为止,我们还没有看到神经元损失,这表明神经元功能障碍的发生没有明显的神经变性。从机制上讲,我们发现突变允许与网格蛋白相互作用,但不能与网格蛋白接头蛋白相互作用。我们在该项目中正在进行的工作将是进一步开发具有更强神经退行性表型的更具攻击性的模型。
英文摘要
We have used genome editing to introduce mutations in the human and mouse genome in the gene DNAJC6 that are associated with a familial, early onset complex form of Parkinson's disease (PD). Because the encoded protein, auxilin, is expressed in neurons, we have focussed on showing how behavior is affected by mutations. Mice show a subtle but significant motor phenotype as they age. However, so far we have not seen loss of neurons, suggesting that neuronal dysfunction occurs without overt neurodegeneration. Mechanistically, we have found that mutations allow for interaction with clathrin but not clathrin adaptor proteins. Our ongoing work in this project will be to further develop a more aggressive model with stronger neurodegenerative phenotypes.
