蜱虫免疫细胞图谱
蜱虫是北美和欧洲大多数媒介传播疾病的罪魁祸首。鹿蜱,肩胛骨蜱,可以传播病原体,包括伯氏疏螺旋体(引起莱姆病)和嗜吞噬细胞无形体(引起无形体病)。了解节肢动物窝藏病原体并将其传播给人类或动物的能力(媒介能力)可能是阻断传播周期的一种有希望的策略。媒介能力的关键决定因素是节肢动物的免疫,因为节肢动物的免疫反应是一个促进病原体选择和传播的动态过程。然而,节肢动物免疫的大部分知识都是从昆虫的研究中推断出来的,包括模式生物,如果蝇(Drosophila melanogaster)和蚊子,它们在生理、遗传和生活方式上与蜱虫有很大不同。先前的研究表明,蜱虫的免疫过程与昆虫不同。然而,对蜱虫免疫及其如何塑造蜱虫媒介能力的机制见解仍然有限。Rolandelli等人最近在《自然通讯》上发表的一项研究调查了蜱在感染和吸血过程中被称为血细胞的特殊免疫细胞的功能和机制。蜱虫体内有三种不同的血细胞群:原血细胞,是浆细胞和粒细胞的前体;浆细胞,主要是吞噬细胞;粒细胞释放分泌因子,也具有吞噬作用。作者在三组不同的血细胞中发现了不同的转录簇。血细胞通过显示独特的代谢、增殖和免疫转录谱对血液摄食和感染作出反应。此外,当吞噬血细胞被耗尽时,观察到嗜吞噬单胞杆菌感染的相应减少,这表明血细胞是细菌的目标,在蜱中定植和传播。

期刊介绍: Nature Microbiology aims to cover a comprehensive range of topics related to microorganisms. This includes: Evolution: The journal is interested in exploring the evolutionary aspects of microorganisms. This may include research on their genetic diversity, adaptation, and speciation over time. Physiology and cell biology: Nature Microbiology seeks to understand the functions and characteristics of microorganisms at the cellular and physiological levels. This may involve studying their metabolism, growth patterns, and cellular processes. Interactions: The journal focuses on the interactions microorganisms have with each other, as well as their interactions with hosts or the environment. This encompasses investigations into microbial communities, symbiotic relationships, and microbial responses to different environments. Societal significance: Nature Microbiology recognizes the societal impact of microorganisms and welcomes studies that explore their practical applications. This may include research on microbial diseases, biotechnology, or environmental remediation. In summary, Nature Microbiology is interested in research related to the evolution, physiology and cell biology of microorganisms, their interactions, and their societal relevance.
