干扰素 (IFN) 是病毒感染先天免疫反应中的关键宿主细胞因子,最近的工作已经确定了 IFN 亚型在调节感染不同方面的独特作用。目前出现的一个共同主题是,III 型干扰素对于粘膜屏障部位的局部感染控制至关重要,而 I 型干扰素对于广泛的全身感染控制很重要。肠道是探索这些影响的一个特别感兴趣的部位,因为它除了是多种病原体的进入口之外,还是一个复杂的组织,具有多种细胞类型以及肠道微生物群的存在。在这里,我们重点关注 I 型和 III 型干扰素在控制肠道病毒中的作用,讨论这些细胞因子下游信号传导的已知信息,包括特定干扰素刺激基因的诱导。我们回顾了病毒逃避干扰素反应的策略、干扰素对肠道的影响、干扰素与微生物群之间的相互作用,并简要讨论了干扰素在控制其他屏障位点病毒感染中的作用。增强对干扰素在控制病毒感染中协调作用的了解可能有助于抗病毒治疗策略的制定;在这里,我们强调未来探索的潜在途径。
Interferons (IFNs) are key host cytokines in the innate immune response to viral infection, and recent work has identified unique roles for IFN subtypes in regulating different aspects of infection. Currently emerging is a common theme that type III IFNs are critical in localized control of infection at mucosal barrier sites, while type I IFNs are important for broad systemic control of infections. The intestine is a particular site of interest for exploring these effects, as in addition to being the port of entry for a multitude of pathogens, it is a complex tissue with a variety of cell types as well as the presence of the intestinal microbiota. Here we focus on the roles of type I and III IFNs in control of enteric viruses, discussing what is known about signaling downstream from these cytokines, including induction of specific IFN-stimulated genes. We review viral strategies to evade IFN responses, effects of IFNs on the intestine, interactions between IFNs and the microbiota, and briefly discuss the role of IFNs in controlling viral infections at other barrier sites. Enhanced understanding of the coordinate roles of IFNs in control of viral infections may facilitate development of antiviral therapeutic strategies; here we highlight potential avenues for future exploration.
