SignificanceDiabetic neuropathy is a commonly occurring complication of diabetes that affects hundreds of millions of patients worldwide. Patients suffering from diabetic neuropathy experience abnormal sensations and have damage in their peripheral nerve axons as well as myelin, a tightly packed Schwann cell sheath that wraps around axons to provide insulation and increases electrical conductivity along the nerve fibers. The molecular events underlying myelin damage in diabetic neuropathy are largely unknown, and there is no efficacious treatment for the disease. The current study, using a diabetic mouse model and human patient nerve samples, uncovered a molecular mechanism underlying myelin sheath damage in diabetic neuropathy and provides a potential treatment strategy for the disease.
意义
糖尿病性神经病是一种常见的糖尿病并发症,影响着全球数以亿计的患者。患有糖尿病性神经病的患者会出现异常感觉,并在外周神经轴突和髓鞘中受到损伤,髓鞘是一种紧密包裹轴突的雪旺细胞鞘,提供绝缘并增加神经纤维的导电性。糖尿病性神经病中髓鞘损伤的分子事件在很大程度上尚不清楚,并且该疾病也没有有效的治疗方法。本研究使用糖尿病小鼠模型和人类患者的神经样本,揭示了糖尿病性神经病中髓鞘鞘损伤的分子机制,并为该疾病提供了一种潜在的治疗策略。
