[Research progress on metal pollutants inducing neurotoxicity through ferroptosis]. [PDF]
Zhejiang Da Xue Xue Bao Yi Xue Ban研究证实多种金属污染物暴露可诱导神经毒性，并与神经系统相关疾病的发生发展密切相关。铁死亡是细胞响应金属污染物暴露的细胞死亡方式，其与氧化应激、铁代谢、脂质过氧化等密切相关。近年研究发现，在铅、镉、锰、镍和锑等金属诱导的神经毒性中铁死亡发挥重要作用，如铅暴露通过氧化应激、铁代谢紊乱和炎症触发铁死亡；镉可通过铁离子代谢、氧化应激以及铁死亡相关信号通路引发铁死亡；锰可通过线粒体功能障碍、铁代谢紊乱和氧化应激促进铁死亡；镍可通过氧化应激影响线粒体功能以及破坏铁稳态并促进其中枢神经系统的脂质过氧化，激活铁死亡 ...
