Historically, amyloids were perceived as toxic/irreversible protein aggregates associated with neurodegenerative disorders including Alzheimer's and Parkinson's diseases. Recent papers are challenging this perception by uncovering widespread cellular roles for physiological amyloidogenesis. These findings suggest that the amyloid-fold should be considered, alongside the native-fold and unfolded configurations, as a physiological and reversible protein organization.
从历史上看,淀粉样蛋白被视为与包括阿尔茨海默病和帕金森病在内的神经退行性疾病相关的有毒/不可逆蛋白质聚集体。最近的论文通过揭示生理性淀粉样蛋白生成的广泛细胞作用,对这一观念提出了挑战。这些发现表明,淀粉样折叠应与天然折叠和未折叠构象一起,被视为一种生理性且可逆的蛋白质组织形式。
