项目摘要

PROJECT SUMMARY Therapies (drugs and genetics-based) in Duchenne Muscular Dystrophy (DMD) are targeted towards improving muscle function and arresting the progression of disease. As a result, the skeletal and even the cardiac musculature are well researched. However, studies focusing on brain structure have been sparse even though varying cognitive deficits have been reported across the spectrum. With advancing treatments, such as exon skipping, as well as steroid alternatives such as VBP15 moving to human trials, there is renewed optimism about improving the life expectancy and quality of patients with DMD. Consequently, a better understanding of the brain structure and its putative link with cognitive function becomes important. Our plan is to collect pilot brain imaging data in 36 children (24 children with DMD and 12 healthy controls, both 8~21 years) using cutting-edge imaging protocols from the Human Connectome Project. Our overarching goal is to identify a brain connectivity biomarker of cognition in DMD by investigating the potential of structural neuroimaging signatures and functional connectomic motifs and relating them to gene expression profiles in the brain.

项目摘要 Duchenne肌肉营养不良（DMD）的疗法（基于药物和遗传学）的目标是改善肌肉功能并阻止疾病的进展。结果，骨骼甚至心脏肌肉组织经过深入研究。但是，尽管在整个频谱中都报道了不同的认知缺陷。通过前进的治疗，例如外显子跳过，以及类固醇替代方法，例如VBP15转向人类试验，对改善DMD患者的预期寿命和质量。因此，更好地理解大脑结构及其与认知功能的推定联系变得很重要。我们的计划是收集飞行员大脑使用尖端人类连接项目的成像协议。我们的总体目标是确定大脑连通性通过研究结构神经成像特征和功能的潜在，DMD中认知的生物标志物连接组基序并将其与大脑中的基因表达谱有关。
