德国海德堡大学研究者的实验结果提示，铜离子可能与震颤麻痹症（即帕金森病）的病因有关。震颤麻痹症患者在某一脑区产生蛋白斑块，称淀粉样蛋白pA4，该脑区与思维、学习、记忆等活动有关。淀粉样蛋白从另一蛋白淀粉样蛋白前体转化而成，这前体在体内另有功能，包括转运有重要 Experimental results from researchers at Heidelberg University in Germany suggest that copper ions may be involved in the etiology of Parkinsonism (Parkinson’s disease). Parkinsonism patients produce protein plaques in a brain area, called amyloid pA4, the brain area and thinking, learning, memory and other activities. Amyloid is transformed from another protein amyloid precursor, which has another function in vivo, including transport is important
