- 요약Enteroviruses (EVs) comprise a large genus of positive-sense single-stranded RNA viruses and are among the most common human infectious agents. EVs cause a wide range of diseases and recent outbreaks of several emerging EVs have been associated with severe neuropathogenesis highlighting their ongoing threat to public health. Apart from a vaccine against PV and two vaccines against EV-A71 in China, there are currently no approved antivirals or therapeutics to treat enterovirus infections. Thus, there is a pressing need to develop novel strategies for combating these medically important pathogens. Host-directed therapy (HDT) is an emerging strategy in the field of antivirals that aims to control viral infections by interfering with host cellular pathways. Evaluation of host targets for use in HDT is dependent on a comprehensive understanding of how a pathogen causes disease. In recent years, our understanding of how EVs co-opt cellular functions and cause disease has greatly accelerated with the advent of unbiased genetic and proteomic technologies and the use of human organoids to more accurately represent human viral infections. This thesis presents examples of applying genome-scale genetic screens and human spinal cord organoids to study how enteroviruses interact with host proteins to cause pathogenesis.In Chapter 1 of this thesis, we introduce enteroviruses as significant human pathogens, compare direct-acting antivirals and host-directed therapies, describe tools for unbiased discovery of host factors co-opted by EVs to promote their infection, and evaluate current model systems used for investigating how EVs cause disease. In Chapter 2, we conducted a comprehensive review on the molecular mechanisms by which neurotropic enteroviruses replicate and co-opt host cellular factors. In Chapter 3, we determined the molecular structure of the host factor SETD3 in complex with the enterovirus protease 2A and showed that formation of this complex is essential for enterovirus infection. In Chapter 4, we describe a previously undocumented role of inositol phosphate kinases, through a CRISPR-Cas9 screen, in regulating enterovirus infection. In Chapter 5, we utilize human spinal cord organoids as a novel model system to uncover unique infection mechanisms providing insights into how EVs cause neuropathogenesis in the central nervous system. Finally, in chapter 6, we draw conclusions and discuss future perspectives on genetic screens, host-directed therapies and the use of organoids as novel model systems to better understand mechanisms of disease and evaluate new therapeutic strategies for controlling infections.
