Described herein is a composition for converting a non-pathogenic prion protein (“PrP
N
”) into a prion protein in a pathogenic conformation (“PrP
Path
”) comprising a lipid and a polyanion. Also described are methods of (1) using the composition to convert a PrP
N
to a PrP
Path
, (2) identifying a potential therapeutic substance affecting PrP
Path
, and (3) diagnosing PrP
Path
infection in a subject using the composition and at least one cycle of protein misfolding cyclic amplification.
本文描述了一种将非致病性朊蛋白质(“Pr
PN”)转化为致病构象的朊蛋白质(“PrPPath”)的组合物,包括脂质和多聚阴离子。还描述了使用该组合物进行以下方法的方法:(1)将Pr
PN转化为PrPPath,(2)鉴定影响PrPPath的潜在治疗物质,以及(3)使用该组合物和至少一个蛋白质错配循环扩增周期诊断主体中的PrPPath感染。
