利什曼病是一个全球性的健康问题,影响全球超过20亿人。最近的研究进展表明,细胞质传感器和炎性小体在利什曼原虫属的关键作用。感染和发病机制。具体而言,一些研究集中在利什曼病中的IL-1β和IL-18的作用,包括IL-1β样受体家族、含pyrin结构域的蛋白3(NLRP 3)炎性体和炎性体相关细胞因子。尽管有这些研究,但我们对利什曼原虫感染过程中导致NLRP 3炎性小体激活的引发和激活事件的理解仍然不足。感染有限。此外,NLRP 3是否在利什曼原虫属中起保护性或致病性作用。感染问题远未得到解决,一些研究显示了保护作用,另一些研究显示了致病作用。在这篇综述中,我们对文献进行了批判性的回顾,以提供利什曼原虫感染期间NLRP 3炎性小体激活所需的启动和激活信号的最新信息。感染最后,我们提供了一个全面的文献综述,以调和在利什曼原虫属期间观察到的NLRP 3炎性小体的保护作用与致病作用的差异。感染
Leishmaniasis is a global health problem that affects more than 2 billion people worldwide. Recent advances in research have demonstrated critical roles for cytoplasmic sensors and inflammasomes during Leishmania spp. infection and pathogenesis. Specifically, several studies have focused on the role of nod-like receptor family, pyrin domain-containing protein 3 (NLRP3) inflammasome and inflammasome-associated cytokines IL-1β and IL-18 in leishmaniasis. Despite these studies, our understanding of the priming and activation events that lead to NLRP3 inflammasome activation during Leishmania spp. infection is limited. Furthermore, whether NLRP3 plays a protective or pathogenic role during Leishmania spp. infection is far from resolved, with some studies showing a protective role and others showing a pathogenic role. In this review, we performed a critical review of the literature to provide a current update on priming and activating signals required for NLRP3 inflammasome activation during Leishmania spp. infection. Finally, we provide a thorough review of the literature to reconcile differences in the observed protective vs pathogenic roles of the NLRP3 inflammasome during Leishmania spp. infection.
