The aim of this study was to explore the expression of follicle suppressor-like protein 1 (FSTL1) in chronic sinusitis and its possible association with type 2 inflammation.Patients and Methods: This study included 34 CRS patients (24 ECRS, 10 non-ECRS) and 10 controls. Hematoxylin-eosin (HE) staining to observe the pathomorphological changes of these three groups of tissue specimens in detail, Immunohistochemistry (IHC), real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) technology and Western blotting (WB) were used to evaluate the expression levels of FSTL1 and type 2 inflammatory cytokines IL-4, IL-5, and IL-13 in the three groups.Results: In the ECRS group, there was thickening of the tissue mucosa and hyperplasia of glands, along with a significant infiltration of inflammatory cells and eosinophils. The experimental results showed that the expression levels of FSTL1 and type 2 inflammatory cytokines IL - 4, IL - 5, and IL - 13 were higher in the ECRS and non - ECRS groups than in the control group (P< 0.05). Additionally, FSTL1 and IL-4, IL-5, IL-13 were positively correlated in the ECRS group(P< 0.05).Conclusion: FSTL1, IL-4, IL-5 and IL-13 were highly expressed in chronic sinusitis, and FSTL1 was positively correlated with IL-4, IL-5 and IL-13 in the ECRS group, suggesting that FSTL1 contributes to the development of type 2 inflammation in ECRS, and FSTL1 may serve as a potential therapeutic target for ECRS.Keywords: chronic sinusitis, follicle suppressor-like protein 1, type 2 inflammation |
