- 为什么会有朊病毒这种蛋白质存在? - 知乎
朊病毒吸引了很多科学家的兴趣,甚至现在还有一本叫做Prion(《朊蛋白》)的学术期刊。 “为什么会有朊病毒的存在”,这个问题实际上可以分为两个部分,一是客观性的,即朊病毒存在的意义是什么,它发挥了什么积极作用吗?

Prion diseases are a group of rare, uniformly fatal neurodegenerative diseases In humans they occur in three forms: sporadic (85% to 90% of cases), genetic (10% to 15%), and acquired (<1%) Prions, or proteinaceous infectious particles, are the misshaped proteins responsible for causing transmissible spongiform encephalopathies, or prion diseases

再说Prion型蛋白质既然秀的如此突出,那它有什么样的进化地位呢? 我觉得它和细胞蛇是很相似的,都广泛分布在原核、动物、植物之中,呈现出了一定的保守性和广泛性,在这个方面,可以说它是所有生物共有的一类蛋白质形态;

朊毒体由错误折叠的朊毒体蛋白(英语:PrP)(prion protein, PrP)聚集组成。 它能够诱导在 神经细胞 上原本是正常结构的朊毒体蛋白转变为错误结构并进行聚集反应(英语: protein aggregation ),借由这个机制引入新的朊毒体蛋白,不断自我复制并传递至邻近细胞,最终扩散至整个脑部。

英语中的prion 是由protein 和infection 拼接而成的混成词,全称是proteinaceous infectious particle,为“蛋白质感染颗粒”之意。 “朊病毒”之译名由中国蛋白质生化专家曹天钦提出,中文的“朊”(拼音:ruǎn,注音:ㄖㄨㄢˇ)为蛋白质的别称。

Paget’s disease of bone (PDB) is a chronic localised bone remodelling disorder characterised by increased bone resorption, bone formation, and remodelling, which may lead to major long-bone and skull deformities
