Abstract

SUMMARYSeveral examples of high-impact cross-species transmission of newly emerging or re-emerging bat-borne viruses, such as Sudan virus, Nipah virus, and severe acute respiratory syndrome coronavirus 2, have occurred in the past decades. Recent advancements in next-generation sequencing have strengthened ongoing efforts to catalog the global virome, in particular from the multitude of different bat species. However, functional characterization of these novel viruses and virus sequences is typically limited with regard to assessment of their cross-species potential. Our understanding of the intricate interplay between virus and host underlying successful cross-species transmission has focused on the basic mechanisms of entry and replication, as well as the importance of host innate immune responses. In this review, we discuss the various roles of the respective molecular mechanisms underlying cross-species transmission using different recent bat-borne viruses as examples. To delineate the crucial cellular and molecular steps underlying cross-species transmission, we propose a framework of overall characterization to improve our capacity to characterize viruses as benign, of interest, or of concern.

新发病毒感染中跨物种传播的分子决定因素。
摘要在过去几十年中,发生了几起新出现或再次出现的蝙蝠传播病毒(如苏丹病毒、尼帕病毒和严重急性呼吸系统综合征冠状病毒 2)跨物种传播的重大事件。下一代测序技术的最新进展加强了对全球病毒组的编目工作,特别是对来自多种不同蝙蝠物种的病毒组的编目工作。然而,这些新型病毒和病毒序列的功能特征描述通常仅限于对其跨物种潜力的评估。我们对成功跨物种传播所依赖的病毒与宿主之间错综复杂的相互作用的理解主要集中在病毒进入和复制的基本机制以及宿主先天免疫反应的重要性上。在这篇综述中,我们将以近期不同的蝙蝠传播病毒为例,讨论跨物种传播背后各自分子机制的各种作用。为了描述跨物种传播的关键细胞和分子步骤,我们提出了一个整体特征描述框架,以提高我们将病毒描述为良性、相关或令人担忧的病毒的能力。

期刊介绍: Microbiology and Molecular Biology Reviews (MMBR), a journal that explores the significance and interrelationships of recent discoveries in various microbiology fields, publishes review articles that help both specialists and nonspecialists understand and apply the latest findings in their own research. MMBR covers a wide range of topics in microbiology, including microbial ecology, evolution, parasitology, biotechnology, and immunology. The journal caters to scientists with diverse interests in all areas of microbial science and encompasses viruses, bacteria, archaea, fungi, unicellular eukaryotes, and microbial parasites. MMBR primarily publishes authoritative and critical reviews that push the boundaries of knowledge, appealing to both specialists and generalists. The journal often includes descriptive figures and tables to enhance understanding. Indexed/Abstracted in various databases such as Agricola, BIOSIS Previews, CAB Abstracts, Cambridge Scientific Abstracts, Chemical Abstracts Service, Current Contents- Life Sciences, EMBASE, Food Science and Technology Abstracts, Illustrata, MEDLINE, Science Citation Index Expanded (Web of Science), Summon, and Scopus, among others.
