However, the mechanisms by which PLpro-mediated immune evasion leads to inflammatory responses are not well understood. In this study, we demonstrate for the first time that PLpro induces inflammation in colonic epithelial cells and colonic inflammation in a mouse model, acting through the ISG15 signaling pathway. Using high-throughput screening, we identified two natural product-derived compounds, coptisine sulfate and (+)-shikonin, that inhibit the interaction between PLpro and ISG15 at the PLpro/ISG15 interface. We further investigated the mechanism of action of these two inhibitors using surface plasmon resonance, thermal shift assays, molecular docking, and molecular simulation studies. Importantly, both coptisine sulfate and (+)-shikonin were able to reduce intestinal inflammation in the PLpro-induced mouse model. These findings provide novel insights into how the SARS-CoV-2 PLpro can drive inflammatory responses and introduce two natural compound-based inhibitors that may offer a new approach to alleviate gastrointestinal complications associated with COVID-19 infection.

Host factors, including noncoding RNAs have been found to be participated in the replication of IAV. However, the mechanism by which circular RNAs (circRNAs) regulating IAV replication remains unclear. By taking the approach of RNA deep sequencing to analyze the circRNA profiles of A549 cells upon IAV infection, we identified that circular CREB binding protein (circCBP) is significantly upregulated after IAV infection or interferon (IFN) treatment. Overexpression of circCBP inhibited IAV replication, while knockdown of circCBP promoted viral replication, indicating that circCBP inhibits IAV replication. We found that circCBP interacts with the viral nucleoprotein (NP) and reduces its interaction with viral polymerase subunits PB1 and PB2, and consequently blocks the vRNP activity. CircCBP can also bind with nonstructural protein 1 (NS1) and alleviate the inhibitory effect of NS1 on antiviral immune response. In addition, circCBP binds with the major stress granule proteins such as G3BP1. Further study revealed that circCBP enhances the oligomerization of G3BP1, which in turn promotes the formation of stress granules and the transcription of IFN-β. Our study reveals the novel functions of circCBP in regulating virus replication and stress granule-related antiviral immune response, providing a new clue to develop circRNA-based antiviral inhibitors.</p>\u0000 </div>","PeriodicalId":16354,"journal":{"name":"Journal of Medical Virology","volume":"97 6","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144264514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether and how RSV and RSV-induced IL-33 contribute to this process are still unclear. In vivo, 7-day-old C57BL/6 mice were infected perinasally with RSV, then viral replication, lung inflammation and barrier integrity were evaluated at various time points postinfection. In vitro, human epithelial cells were infected with RSV in the presence or absence of IL-33, and the expression and localization of apical junction complex proteins (AJC) were assessed by western blot analysis and immunofluorescence staining. The involvement of components of the IL-33/ST2/MyD88 axis was further verified through blockade of endogenous IL-33 signaling and pharmacological inhibition of MyD88. Exposure to RSV infection resulted in impairment of the airway epithelial barrier, as indicated by reduced expression of tight junction proteins (ZO-1, Occludin) and adherents junction protein (E-cadherin) in the lung tissues. These effects on epithelial barrier disruption were significantly attenuated in <i>St2</i><sup>-/-</sup> mice compared with wild-type controls. In vitro, the RSV-induced epithelial barrier disruption was exacerbated by topical application of exogenous IL-33, partially through activation of MyD88-mediated NF-κB signaling. Notably, knockdown of <i>St2</i> by siRNA transfection or pharmacological inhibition of MyD88 partially restored the expression of E-cadherin, ZO-1 and Occludin in RSV-infected epithelial cells. RSV infection triggers robust IL-33 release from airway epithelial cells, leading to disrupted expression of AJC protein via activation of the MyD88-dependent NF-κB signaling pathway.
