455. 锰失衡与莱姆病治疗新策略

from 知为谁 · host 知为谁

一篇来自西北大学新闻报道的文章讨论了导致莱姆病的伯氏疏螺旋体细菌的一个新弱点,该研究由西北大学和美国军警健康科学大学的科学家合作完成。这项研究发现,锰元素对于伯氏疏螺旋体来说是一把双刃剑,它既是细菌用来抵御宿主免疫系统的“盔甲”,也是其弱点所在。研究人员使用电子顺磁共振(EPR)成像和电子核双共振(ENDOR)光谱技术来描绘锰在细菌内部的防御机制,发现干扰锰的平衡——无论是使其匮乏还是过载——都会使细菌变得脆弱。这项发现可能为开发针对莱姆病的新疗法提供思路,特别是因为当前长期使用抗生素存在副作用。该研究显示,针对细菌管理锰的方式进行干预,有望削弱病原体,使其更容易被免疫系统或治疗手段清除。内容来源: https://news.northwestern.edu/stories/2025/11/manganese-is-lyme-diseases-double-edge-sword
