 SCI TRANSL MED :糖尿病神经疼痛的“根源”已确定,患者再也不用忍受痛苦

伦敦国王学院的一项新研究揭示了,糖尿病患者慢性神经疼痛的分子基础,研究结果发表在《科学转化医学》杂志中,在报告中,研究人员确定了神经痛的目标,为治疗找到了目标。

大约四分之一的糖尿病患者会发展神经损伤引起的慢性疼痛,这又称为糖尿病性神经病,是由于高血糖引起的。症状包括刺痛感觉,疼痛,极度的敏感,脚和手的病变,也会逐渐向上蔓延到腿和手臂。疼痛会逐渐发展,也会加剧肥胖,成为2型糖尿病恶化的一个自我循环。

糖尿病患者的疼痛非常难治,因为分子水平的理解知之甚少。伦敦国王学院的新研究提供了第一个分子证据,单个蛋白质分子HCN2本身可以负责一个复杂疼痛,如糖尿病患者的疼痛。

在试验过程中,研究人员使用糖尿病小鼠模型,他们注意到HCN2启动神经纤维的信号,导致疼痛的感觉。他们还发现,阻断HCN2的活动,或把它完全从痛觉神经纤维中移走,则可以完全停止疼痛的感觉。

来自伦敦大学国王学院沃尔夫森中心的研究人员表示:“肥胖人数在世界范围内不断增加,这就带来了很多相关的疾病,2型糖尿病就是其中之一。据研究,多达四分之一的糖尿病患者患有神经疼痛,但目前并没有有效的治疗方法来应对这一问题,因此人们通常必须忍受这种长期的痛苦。”

“我们的研究揭示了推动糖尿病小鼠疼痛的分子机制,这一发现有助于开发应对神经疼痛的新方法,帮助糖尿病患者终止疼痛。”
