Enteroviruses, such as EV-A71 and CVA16, mainly infect the human gastrointestinal tract. Human coronaviruses, including SARS-CoV and SARS-CoV-2, have been variably associated with gastrointestinal symptoms. We aimed to optimize the human intestinal organoids and hypothesize that these optimized intestinal organoids can recapitulate enteric infections of enterovirus and coronavirus. We demonstrate that the optimized human intestinal organoids enable better simulation of the native human intestinal epithelium, and that they are significantly more susceptible to EV-A71 than CVA16. Higher replication of EV-A71 than CVA16 in the intestinal organoids triggers a more vigorous cellular response. However, SARS-CoV and SARS-CoV-2 exhibit distinct dynamics of virus-host interaction; more robust propagation of SARS-CoV triggers minimal cellular response, whereas, SARS-CoV-2 exhibits lower replication capacity but elicits a moderate cellular response. Taken together, the disparate profile of the virus-host interaction of enteroviruses and coronaviruses in human intestinal organoids may unravel the cellular basis of the distinct pathogenicity of these viral pathogens.
肠道病毒,如 EV-A71 和 CVA16,主要感染人类胃肠道。人类冠状病毒,包括 SARS-CoV 和 SARS-CoV-2,与胃肠道症状有不同程度的关联。我们旨在优化人类肠道类器官,并假设这些优化的肠道类器官可以再现肠道病毒和冠状病毒的肠道感染。我们证明,优化的人类肠道类器官能够更好地模拟天然的人类肠道上皮,并且它们对 EV-A71 的敏感性明显高于 CVA16。EV-A71 在肠道类器官中的复制高于 CVA16,会引发更强烈的细胞反应。然而,SARS-CoV 和 SARS-CoV-2 表现出不同的病毒-宿主相互作用动力学;SARS-CoV 的更强烈增殖会引发最小的细胞反应,而 SARS-CoV-2 的复制能力较低,但会引发适度的细胞反应。总之,肠道病毒和冠状病毒在人类肠道类器官中的病毒-宿主相互作用的不同特征可能揭示了这些病毒病原体不同致病性的细胞基础。
