Desminopathy R350P is a human myopathy that is characterized by the progressive loss of muscle fiber organization. This results in the loss of muscle size, mobility, and strength. In desminopathy, inflammation affects muscle homeostasis and repair, and contributes to progressive muscle deterioration. Mitochondria morphology was also suggested to affect desminopathy progression. Epicatechin (Epi)-a natural compound found in cacao-has been proposed to regulate inflammatory signaling and mitochondria morphology in human and animal models. Hence, we hypothesize chronic Epi consumption to improve inflammatory pathway and mitochondria morphology in the peripheral blood mononuclear cells (PBMCs) of a desminopathy R350P patient. We found that 12 weeks of Epi consumption partially restored TRL4 signaling, indicative of inflammatory signaling and mitochondria morphology in the desminopathy patient. Moreover, Epi consumption improved blood health parameters, including reduced HOMA-IR and IL-6 levels in the desminopathy patient. This indicates that Epi consumption could be a useful tool to slow disease progression in desminopathy patients.
结蛋白病R350P是一种人类肌病,其特征是肌纤维组织逐渐丧失。这导致肌肉大小、活动能力和力量的丧失。在结蛋白病中,炎症会影响肌肉内环境稳定和修复,并导致肌肉进行性退化。线粒体形态也被认为会影响结蛋白病的进展。表儿茶素(Epi)——一种存在于可可中的天然化合物——已被提出在人和动物模型中调节炎症信号和线粒体形态。因此,我们假设长期摄入Epi可改善结蛋白病R350P患者外周血单核细胞(PBMC)中的炎症途径和线粒体形态。我们发现,摄入Epi 12周可部分恢复TRL4信号,这表明结蛋白病患者存在炎症信号和线粒体形态。此外,摄入Epi改善了血液健康参数,包括降低了结蛋白病患者的HOMA-IR和IL-6水平。这表明摄入Epi可能是减缓结蛋白病患者疾病进展的一种有用手段。
