吸虫病在全球范围内导致数百万人患病,但由于缺乏商业疫苗,导致过度依赖少数单一疗法来控制感染。由于抗药性吸虫种群正在出现,需要更深入地了解寄生虫生物学和宿主相互作用,以确定新的药物靶点和免疫原性疫苗候选人。基于质谱的蛋白质组学是实现这一目标的关键工具。最近的研究利用了更广泛的可用性注释蠕虫基因组,以实现更大的复盖率吸虫蛋白质组和发现新的方面的主机寄生虫的关系。本文主要介绍这些最新进展。这些包括如何蛋白质组分的吸虫细胞外囊泡已经深入了解他们的生物起源和细胞相互作用。此外,转录组/蛋白质组数据集的整合揭示了肝吸虫毒力因子和免疫调节剂的选定家族的表达和分泌是根据哺乳动物宿主内的寄生虫发育和迁移进行调节的。此外,我们讨论了使用免疫蛋白质组学作为一种工具,以确定与保护性抗体反应相关的候选疫苗。最后,我们强调如何建立和新兴的技术,如激光显微切割和单细胞蛋白质组学,可以被利用来解决离散吸虫组织或细胞类型的蛋白质谱,结合功能工具,可以精确定位吸虫控制的最佳目标。
Trematodes cause disease in millions of people worldwide, but the absence of commercial vaccines has led to an over-reliance on a handful of monotherapies to control infections. Since drug-resistant fluke populations are emerging, a deeper understanding of parasite biology and host interactions is required to identify new drug targets and immunogenic vaccine candidates. Mass spectrometry-based proteomics represents a key tool to that end. Recent studies have capitalised on the wider availability of annotated helminth genomes to achieve greater coverage of trematode proteomes and discover new aspects of the host–parasite relationship. This review focusses on these latest advances. These include how the protein components of fluke extracellular vesicles have given insight into their biogenesis and cellular interactions. In addition, how the integration of transcriptome/proteome datasets has revealed that the expression and secretion of selected families of liver fluke virulence factors and immunomodulators are regulated in accordance with parasite development and migration within the mammalian host. Furthermore, we discuss the use of immunoproteomics as a tool to identify vaccine candidates associated with protective antibody responses. Finally, we highlight how established and emerging technologies, such as laser microdissection and single-cell proteomics, could be exploited to resolve the protein profiles of discrete trematode tissues or cell types which, in combination with functional tools, could pinpoint optimal targets for fluke control.
