Summary: My translational research program focuses on immunometabolism using mitochondrial disease as a model system. Patients with mitochondrial disease experience life threatening episodes of acute metabolic instability and organ dysfunction brought about by infection termed metabolic decompensation. Our goal is to understand how immune activation during infection contributes to this pathophysiology. This line of research also has implications for organ dysfunction during sepsis, a common problem in the intensive care unit. Since infection is important in patients with mitochondrial disease, we also wish to understand the role of mitochondrial metabolism in immune cell function. Many enzymes involved in mitochondrial metabolism are also expressed in lymphocytes, and have associated diseases. These studies will not only provide insight into immune function in mitochondrial disease patients, but also help define the role of the mitochondria in normal immune cell function.

摘要：我的转化研究计划着重于使用线粒体疾病作为模型系统的免疫代谢。线粒体疾病的患者经历了威胁生命的急性代谢不稳定性和器官功能障碍的生命发作，这被称为代谢代谢失代偿。我们的目标是了解感染过程中的免疫激活如何有助于这种病理生理学。这项研究也对败血症期间器官功能障碍有影响，这是重症监护病房的常见问题。由于感染在线粒体疾病患者中很重要，因此我们也希望了解线粒体代谢在免疫细胞功能中的作用。许多参与线粒体代谢的酶也在淋巴细胞中表达，并且患有相关疾病。这些研究不仅可以洞悉线粒体疾病患者的免疫功能，而且还有助于定义线粒体在正常免疫细胞功能中的作用。
