An in vitro study of the impact of IL-17A and IL-22 on ciliogenesis in nasal polyps epithelium via the Hippo-YAP pathway
Background
Cilia loss and impaired motile ciliary functions are among the typical pathological features of chronic rhinosinusitis with nasal polyps (CRSwNP). IL17A and IL22 are the canonical cytokines of type 3 inflammation, exhibiting similar functional effects on epithelial cells. In this study, we sought to examine the effects of IL17A and IL22 on ciliated cells and investigate the potential involvement of Hippo-YAP signaling in their influence on ciliogenesis.
Methods
We assessed both the mRNA and protein expression levels of IL17A and IL22 in nasal tissues obtained from patients with CRSwNP and compared them to those from healthy controls. To further explore the impact of IL17A and IL22, we established a primary human nasal epithelial cell model using different concentrations (2 ng/mL, 10 ng/mL, 50 ng/mL) for a duration of 28 days in an air-liquid interface culture. Additionally, we employed the inhibitor verteporfin to investigate whether IL17A and IL22 exert their effects on ciliated cells via the Hippo-YAP pathway.
Results
The mRNA and protein levels of IL17A and IL22 in CRSwNP were significantly higher than those in healthy controls, revealing a robust correlation between IL17A and IL22. YAP was highly expressed in the nucleus of ciliated cells in CRSwNP and displayed a positive correlation with clinical symptoms. Both IL17A and IL22 were found to reduce the number of ciliated cells. IL17A, but not IL22, suppressed ciliogenesis by disrupting the proper development and docking of the basal body of ciliated cells, resulting in motile ciliary dysfunctions. Furthermore, the expression of YAP within the nucleus of ciliated cells gradually declined as these cells reached the final stage of differentiation. However, this process was obstructed by IL17A only. YAP inhibitors, such as verteporfin, markedly reversed the effects of IL17A by increasing the proportion of ciliated cells, suppressing nuclear YAP expression in these cells, and enhancing ciliary beating frequency.
Conclusions
Both IL17A and IL22 are overexpressed in nasal epithelium of CRSwNP, which is associated with the impairment of epithelial cell differentiation. Furthermore, IL17A has been shown to exert a disruptive effect on morphogenesis of motile cilia via activation of YAP.
