为制止阿尔茨海默病的发展,一项重要的理论认为应减少脑内一种蛋白碎片(被称作β-淀粉样蛋白)的聚结。例如,为达到这一目标而努力的科学家们正在试验一种疫苗,该疫苗可促使免疫系统将这种淀粉样蛋白从大脑中清除出去。解决这一问题的方法可能会更简单一些。一项在小鼠中进行的研究表明,布洛芬(常见的非处方药物)能减少β-淀粉样蛋白的异常蓄积。研究人员认为,此项发现不但支持了 To stop the development of Alzheimer’s disease, an important theory is that it should reduce the cohesion of a protein fragment (called β-amyloid) in the brain. For example, scientists working to achieve this goal are experimenting with a vaccine that prompts the immune system to remove this amyloid from the brain. The solution to this problem may be simpler. One study in mice showed that ibuprofen, a common over-the-counter drug, reduced the abnormal accumulation of beta-amyloid. The researchers believe that this finding not only supports it
