Additionally, sinus mucosal brushings underwent RT\u2010qPCR to profile inflammatory gene expression.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Patients in the high LMS group demonstrated a significantly greater clinical burden, as indicated by endoscopic scores, nasal symptom scores, and peripheral eosinophil counts. Histological analyses revealed that high LMS correlated with extensive tissue remodeling, including basement membrane thickening, goblet cell hyperplasia, and pronounced mixed eosinophilic and neutrophilic infiltration. Molecular profiling identified a distinct mixed inflammatory signature in the high LMS group: in addition to the expected elevation of Type 2 markers (e.g., IL\u20105, IL\u201013, and CCL26), Type 3 inflammatory genes (e.g., CXCL2, IL\u20101\u03b2, and IL\u20108) were also significantly upregulated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Severe CRSwNP, characterized by a high LMS, exhibits a mixed Type 2\/Type 3 epithelial inflammatory signature. The co\u2010activation of Type 3 pathways alongside Type 2 responses is associated with severe tissue remodeling. These findings further elucidate the complex inflammatory landscape of CRSwNP and suggest that high radiological scores may reflect distinct molecular heterogeneity in patients exhibiting extensive sinus opacification.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/lio2.70466","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T03:53:25Z","timestamp":1781063605000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["High Radiological Severity in\n                    <scp>CRSwNP<\/scp>\n                    Is Associated With a Mixed Type 2\/Type 3 Epithelial Inflammatory Signature"],"prefix":"10.1002","volume":"11","author":[{"given":"Guangfu","family":"Xu","sequence":"first","affiliation":[{"name":"Department of Otolaryngology The Seventh Affiliated Hospital of Sun Yat\u2010Sen University  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Tian","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology The Seventh Affiliated Hospital of Sun Yat\u2010Sen University  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kanghua","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology The Seventh Affiliated Hospital of Sun Yat\u2010Sen University  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunping","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology The Seventh Affiliated Hospital of Sun Yat\u2010Sen University  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2382-0429","authenticated-orcid":false,"given":"Yueqi","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology The Seventh Affiliated Hospital of Sun Yat\u2010Sen University  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8444-9328","authenticated-orcid":false,"given":"Chang","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology The Seventh Affiliated Hospital of Sun Yat\u2010Sen University  Shenzhen China"},{"name":"Scientific Research Center, The Seventh Affiliated Hospital of Sun Yat\u2010Sen University  Shenzhen Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,9]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaci.2011.07.049"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2024.1356298"},{"issue":"2","key":"e_1_2_9_4_1","first-page":"151","article-title":"State\u2010of\u2010the\u2010Art Overview on Biological Treatment for CRSwNP","volume":"59","author":"Hellings P.
