朊病毒病是一组独特的传染性慢性神经退行性疾病，目前尚无治愈方法。虽然朊病毒感染不会刺激受感染个体的适应性免疫应答，但某些免疫细胞群体的作用可对疾病发病机制产生重大影响。感染后，外周获得性朊病毒靶向次级淋巴器官（SLO）（如淋巴结和脾脏）中的特异性免疫细胞对于疾病向大脑的有效传播至关重要。一旦朊病毒到达大脑，与其他免疫细胞群的相互作用可以提供宿主保护或加速神经变性。在这篇综述中，我们提供了一个详细的帐户，如炎症，衰老和病原体共感染的因素可以影响朊病毒疾病的发病机制和易感性。例如，我们讨论了特定免疫细胞群的丰度、功能和激活状态的变化如何影响朊病毒疾病通过外周途径的传播。我们还描述了全身性炎症对受感染个体大脑中某些胶质细胞亚群的影响如何加速神经退行性变。详细了解影响朊病毒疾病传播和发病机制的因素对于开发新的干预策略至关重要。
Prion diseases are a unique group of infectious chronic neurodegenerative disorders to which there are no cures. Although prion infections do not stimulate adaptive immune responses in infected individuals, the actions of certain immune cell populations can have a significant impact on disease pathogenesis. After infection, the targeting of peripherally-acquired prions to specific immune cells in the secondary lymphoid organs (SLO), such as the lymph nodes and spleen, is essential for the efficient transmission of disease to the brain. Once the prions reach the brain, interactions with other immune cell populations can provide either host protection or accelerate the neurodegeneration. In this review, we provide a detailed account of how factors such as inflammation, ageing and pathogen co-infection can affect prion disease pathogenesis and susceptibility. For example, we discuss how changes to the abundance, function and activation status of specific immune cell populations can affect the transmission of prion diseases by peripheral routes. We also describe how the effects of systemic inflammation on certain glial cell subsets in the brains of infected individuals can accelerate the neurodegeneration. A detailed understanding of the factors that affect prion disease transmission and pathogenesis is essential for the development of novel intervention strategies.
