Furthermore, we have utilized integrated bioinformatics to comprehensively elucidate the regulatory mechanisms and identify the key regulatory genes implicated in this phenomenon.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Our histopathological examination revealed significant pathological changes in the skin and muscle, characterized by necrosis and inflammation. Moreover, tissue remodeling occurred, with perimysium degeneration and lesion invasion into the muscle along the endomysium, accompanied by a transformation of type I collagen into a mixture of type I and type III collagens in the perimysium and muscle bundles. Our eukaryotic transcriptomic and 4D label-free analyses demonstrated a predominantly immune pathway response in both the skin and muscle, with downregulation observed in several cell signaling pathways that focused on focal adhesion-dominated cell signaling pathways. The upregulated genes included\n interleukins<\/jats:italic>\n (IL)-1 and -6,\n chemokines<\/jats:italic>\n , and\n matrix metallopeptidases<\/jats:italic>\n (\n mmp<\/jats:italic>\n )-9 and -13, while several genes were significantly downregulated, including\n col1a<\/jats:italic>\n and col1a1a. Further analysis revealed that these pathways were differentially regulated, with\n mmp<\/jats:italic>\n -9 and\n mmp<\/jats:italic>\n -13 acting as the potential core regulators of cytokine and tissue remodeling pathways. Upregulation of\n NF-\u03baB1<\/jats:italic>\n and\n FOSL-1<\/jats:italic>\n induced by\n IL-17C<\/jats:italic>\n and\n Nox 1\/2<\/jats:italic>\n -based NADPH oxidase may have held matrix metallopeptidase and cytokine-related genes. Also, we confirmed these relevant regulatory pathways by qPCR and ELISA in expanded samples.\n <\/jats:p>\n <\/jats:sec>\n \n Discussion<\/jats:title>\n \n Our findings unequivocally illustrate the occurrence of a cytokine storm and tissue remodeling, mediated by interleukins, chemokines, and MMPs, in the surface of yellow catfish infected with\n V. mimicus<\/jats:italic>\n . Additionally, we unveil the potential bidirectional regulatory role of MMP-9 and MMP-13. These results provide novel perspectives on the intricate immune response to\n V. mimicus<\/jats:italic>\n infection in yellow catfish and highlight potential targets for developing therapies.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.3389\/fimmu.2023.1172849","type":"journal-article","created":{"date-parts":[[2023,5,22]],"date-time":"2023-05-22T00:27:56Z","timestamp":1684715276000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Integrated bioinformatics identifies key mediators in cytokine storm and tissue remodeling during Vibrio mimicus infection in yellow catfish (Pelteobagrus fulvidraco)"],"prefix":"10.3389","volume":"14","author":[{"given":"Yang","family":"Feng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiao","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Fan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Geng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoli","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Ouyang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Defang","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongrui","family":"Guo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huidan","family":"Deng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weimin","family":"Lai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhicai","family":"Zuo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,5,22]]},"reference":[{"key":"B1","first-page":"182","article-title":"Vibriosis","volume-title":"Climate change and infectious fish diseases","author":"Amaro","year":"2020"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1007\/s00595-008-3808-5","article-title":"Mycotic abdominal aortic aneurysm infected by vibrio mimicus: report of a case","volume":"39","author":"Skandalos","year":"2009","journal-title":"Surg Today"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1007\/s10499-022-00921-8","article-title":"Vibriosis outbreaks in farmed Nile tilapia (Oreochromis niloticus) caused by vibrio mimicus and V","volume":"30","author":"Elgendy","year":"2022","journal-title":"Cholerae.
