There is a pressing need to develop therapeutics that can promote brain health with aging. Such therapeutics would postpone the deterioration in cognition and mental health that occurs with age. The proposed research will identify, optimize, and then test in laboratory animals such therapeutics as steps towards future clinical use. The research focus is on mitochondria, the organelle in brain neurons that provides energy and many other functions for neurons to function and remain healthy. Mitochondria become impaired with age; mitochondrial impairment is one of the well-known hallmarks of aging. In pilot studies, we have identified a few new drugs that have the potential to enhance mitochondrial function across age. We will search for and identify five times more to enlarge the set of potential “mitotherapeutics.” These drugs will then be tested in laboratory animals to determine whether they can protect mitochondria from the insults associated with age and enhance brain function; postponing or eliminating the cognitive and mental health issues that occur with age. Drugs with the potential to postpone or eliminate these issues would have an enormous impact on brain health for the late adult and elderly in the U.S. population.

迫切需要开发可以促进大脑健康的治疗方法。此类治疗剂 可以延缓随着年龄增长而出现的认知和心理健康的恶化。拟议研究 将确定，优化，然后在实验室动物中测试这些治疗方法，作为未来临床治疗的步骤。 使用.研究的重点是线粒体，这是大脑神经元中的细胞器，提供能量和许多 其他功能的神经元功能和保持健康。线粒体随着年龄的增长而受损; 线粒体损伤是众所周知的衰老标志之一。在试点研究中，我们确定了一些 新的药物，有可能提高线粒体功能跨越年龄。我们将寻找并识别 五倍以上，以扩大潜在的“有丝分裂疗法”。这些药物将在实验室进行测试 动物，以确定他们是否可以保护线粒体免受与年龄相关的损害，并提高 大脑功能;推迟或消除随着年龄增长而出现的认知和心理健康问题。药物 推迟或消除这些问题的可能性将对后期的大脑健康产生巨大影响。 美国人口中的成年人和老年人。
