阿尔茨海默病( AD)是一种中枢神经系统退行性疾病,现已成为影响老年人生活质量并导致死亡的最严重疾病之一。目前有关AD的发病机制有很多,神经元内钙稳态失调可能为其发病的始发因素。丹曲林属兰尼碱受体拮抗剂,目前用于恶性高热、肌强直的治疗。同时,丹曲林还可使受损神经元内游离钙离子水平趋于正常化,展现出了神经保护作用,可改善AD动物模型的认知功能。“,”Alzheimer disease(AD) is a degenerative disease of the central nervous system,which has become one of the most serious diseases affecting the quality of elder people′s life and may even lead to death.Currently there are many pathogeneses about AD,and calcium homeostasis imbalance of neuron may be the initiating factor of the disease.Dantrolene,an antagonist of ryanodine receptors,is now used for the clinical treatment of malignant hyperthermia and muscle spasms,which can also make the level of calcium in impaired neuron return to normal,exhibiting neuroprotective effects,and has been demonstrated to improve cognitive function of AD animal models.
