OBJECTIVE: To detect the expression of Th17 nuclear factor RORC and cytokines IL-17A and IL-22 and neutrophil marker MPO and their correlations with CRSsNP.
METHOD: RT-PCR was used to detect mRNA expression of RORC, IL-17A and IL-22. Immunohistochemistry was used to assess the IL-17A positive cells in CRSsNP and control. ELISA was used to detect the expression of MPO.
RESULT: CRSsNP had higher mRNA expression of RORC, IL-17A and IL-22 and increased protein expression of MPO. The mRNA expression of RORC, IL-17A and IL-22 was positively correlated with each other but none of them was correlated with the expression of MPO in CRSsNP and control.
CONCLUSION: Both Th17 and neutrophils contribute to the pathogenesis of CRSsNP, however, the neutrophil infiltration may not be recruited by Th17 cytokines.
