The relationship of the expression of thymic stromal lymphopoietin in nasal polyps tissues and Th2 inflammatory response / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To explore the relationship of the expression of thymic stromal lymphopoietin (TSLP) in nasal polyps tissues and the Th2 inflammatory response.@*METHOD@#Sixty patients with nasal polyps were collect ed. The immunohistochemical staining method was used to detect the expression of TSLP in nasal polyps tissues and ELISA method to the expression of IL-4, IL-5, IFN-gamma, IL-13 and analyzed the correlation between them.@*RESULT@#The expression of TSLP in nasal polyp tissues was higher than that in normal inferior turbinate mucosa (P < 0.05). The expression level of IL-4, IL-5, IFN-gamma and IL-13 in nasal polyps tissues were significantly higher than those in control group (P < 0.05). TSLP staining was a statistically significant positive correlation with IL-4, IL5 and IL-13 (r = 0.475, 0.594 and 0.582, respectively, P < 0.01), while inverse correlation with IFN-gamma (r = -0.614, P < 0.01).@*CONCLUSION@#The high expression of TSLP might promote T cell differentiation towards Th2, and participated in the occurrence/development of nasal polyps, aggravated the nose Th2 inflammatory response.
