We are characterizing the CNS phenotypes caused by elevated mtDNA mutation levels and relating these findings to age-related functional changes. Furthermore, we will investigate the affects of ischemic brain injury in these same mice. We have already documented change in cortical thickness and lamination patterns. There are also changes in oxidative energy production and mitochondrial function. These changes parallel cognitive and motor deficiencies in the mtDNA mutators. Drugs that upregulate mitochondrial function are being evaluated.

我们正在表征由 mtDNA 突变水平升高引起的中枢神经系统表型，并将这些发现与年龄相关的功能变化联系起来。 此外，我们将研究缺血性脑损伤对这些小鼠的影响。我们已经记录了皮质厚度和层压模式的变化。氧化能量的产生和线粒体功能也发生了变化。这些变化与 mtDNA 突变体的认知和运动缺陷相似。正在评估上调线粒体功能的药物。
