SerpinB3/B4 Abates Epithelial Cell-Derived CXCL8/IL-8 Expression in Chronic Rhinosinusitis with Nasal Polyps

Figure 3

Localization of SerpinB3 and B4 in nasal tissues. Immunofluorescence staining of SerpinB3 and B4 (both in red) and negative control in nasal tissues collected from ECRSwNP and nonECRSwNP patients and healthy controls. Cell nuclei (blue) were visualized using DAPI counterstaining. Bars = 25 μm. CRSwNP, chronic rhinosinusitis with nasal polyps; ECRSwNP, eosinophilic CRSwNP; SerpinB, serine proteinase inhibitor, clade B, and DAPI, 4^′-6-Diamidino-2- phenylindole dihydrochloride.
