朊毒体

在研究室中,人们研究了牛脑组织上的微小“洞”

朊毒体英语:prion发音为/ˈpriː.ɒn/),又译为朊病毒普里朊蛋白质感染因子蛋白侵染子朊病素普列昂普里昂普利子普昂蛋白普恩蛋白普利恩蛋白等,是一类仅由蛋白质构成感染性物质,不含核酸,被归类为亚病毒因子。

朊毒体与普通蛋白质不同,经120 ~ 130℃加热4小时,紫外线,离子照射,甲醛消毒,并不能把这种传染因子杀灭,对蛋白酶有抗性,但不能抵抗蛋白质强变性剂,如:苯酚、尿酸。

朊毒体会引发哺乳动物的传染性海绵状脑病,包括羊搔痒症、疯牛病、克雅二氏病和库鲁病。该毒体被摄入后会破坏脑组织结构,最终导致患者死亡,目前不可医治。

英语百科

Prion 朊毒体

Heterodimer model of prion propagation
Fibril model of prion propagation.

A prion (/ˈprɒn/) is an infectious agent thought to be the cause of the transmissible spongiform encephalopathies (TSEs). It is composed entirely of protein material, called PrP (short for prion protein), that can fold in multiple, structurally distinct ways, at least one of which is transmissible to other prion proteins, leading to disease that is similar to viral infection. The word prion, coined in 1982 by Stanley B. Prusiner, is a portmanteau derived from protein and infection, hence prion, and is short for "proteinaceous infectious particle", in reference to its ability to self-propagate and transmit its conformation to other proteins.
