Due to its novelty, no antibodies or serological diagnostics for the virus existed prior to the current study. In this study, we developed the first purification method for maize yellow mosaic virus with the goal of generating an antibody and subsequently developing diagnostic tests. Yields of 0.634–1.275 milligrams of virus per kilogram of maize tissue were obtained, which is comparable to the yields obtained for other grass-infecting poleroviruses. Under an electron microscope, purified virus particles appear icosahedral in shape and roughly 30 nm in diameter. A polyclonal antibody was generated against the gradient-purified virus preparation and cross-adsorbed to uninfected maize tissue. The antibody is effective for detection of MaYMV via enzyme-linked immunosorbent assay (ELISA) and western blot. The ELISA could detect virus in quantities as low as 0.395 µg and in 1:32 dilutions of infected plant extract, and the antibody showed little to no cross-reactivity with five closely related viruses. After protein gel electrophoresis and antibody detection, protein bands corresponding in size to two viral structural proteins could be seen: the coat protein of roughly 21 kDa and the readthrough protein, around 72 kDa. Finally, virus particles purified using this protocol were found to be transmissible by the primary aphid vector, <i>Rhopalosiphum maidis</i>, and to cause systemic, symptomatic infection of maize plants, indicating that the vector transmissibility and infectivity of the virus particles were preserved during purification.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"170 4","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we identified host proteins interacting with IBV NSP10 using co-immunoprecipitation (Co-IP) and liquid chromatography-tandem mass spectrometry (LC/MS/MS). Proteomic analysis revealed that interactions of host proteins with NSP10 are involved in processes such as localization, transport, and metabolism, regulation of the cell cycle, and antiviral responses. We further explored the role of NSP10 in these immune and cellular regulation pathways and also confirmed the interaction between NSP10 and the host protein hnRNPA1. Further investigation showed that hnRNPA1 inhibited IBV replication. It is speculated that the binding of hnRNP A1 to NSP10 interferes with the function of the replication complex, thereby inhibiting virus replication. However, co-overexpression of NSP10 and hnRNP A1 partially restored viral replication, suggesting a complex relationship between these two proteins. These findings demonstrate that IBV NSP10 plays a significant role in viral infection and in modulating host cell processes, highlighting its potential as a target for therapeutic interventions.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"170 4","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
