The result is a chain reaction in which more and more protein ends up as prions.

这个链式反应使越来越多的蛋白质变成朊病毒。

Your neurology department loaned me a culture of prions for my research on bovine spongiform encephalopathy.

你们神经科学部门借了我朊病毒培养箱来协助我牛海绵状脑病的研究。

Not if it was a prion disease.

你说什么。

You catch a prion disease by ingesting infected tissue.

而朊病毒存在于人的神经组织里。

All right. To what temperature must you heat beef in order to kill the prion that cses bovinespongiform encephalopathy?

听好了 你要把牛肉加热到什么温度才能把引起牛海绵状脑病(即疯牛病)的朊病毒彻底杀死？

These are quite effective in reducing the prion levels of cultured nerve cells.

它能有效降低体外培养的神经细胞内的朊病毒水平。

Kuru is a Transmissible Spongiform Encephalopathy disease defined by bent and misshapen proteins, or prions, in your brain that degrade neurological function.

Kuru 是一种传染性海绵状脑病， 由大脑中弯曲和畸形的蛋白质或朊病毒定义，会降低神经功能。

But unlike viruses, bacteria, fungi or parasitic infections which contain DNA or RNA, Prions don't, meaning they can't be killed with radiation or heat.

但与含有 DNA 或 RNA 的病毒、细菌、真菌或寄生虫感染不同，朊病毒不含有 DNA 或 RNA，这意味着它们不能被辐射或热量杀死。

A glimmer of hope for a drug that treats disease caused by prions THE epidemic of mad-cow disease in people that some forecast in the 1990s has not, fortunately, come to pass.

药物治疗朊病毒感染疾病的一线希望时至今日，疯牛病没有像上世纪90年代的某些预言说的那样在人群中流行，真是幸运。
