虽然朊病毒与基于核酸的病原体具有传播菌株信息的能力,但尚不清楚它们如何在缺乏这种信息成分的情况下突变并获得适应性。由于朊病毒疾病作为流行病发生,了解这种机制对于实施限制其传播的控制策略以及评估其人畜共患潜力至关重要。在这里,我们回顾了新出现的证据,表明朊病毒蛋白的一级结构与 PrPSc 构象相容性如何决定朊病毒株突变。
While prions share the ability to propagate strain information with nucleic acid based pathogens, it is unclear how they mutate and acquire fitness in the absence of this informational component. Because prion diseases occur as epidemics, understanding this mechanism is of paramount importance for implementing control strategies to limit their spread, and for evaluating their zoonotic potential. Here we review emerging evidence indicating how prion protein primary structures, in concert with PrPSc conformational compatibility, determine prion strain mutation.
