Abstract
Objective:To observe the expression and function of TH17 cells in patients with chronic obstructive pulmonary disease(COPD).Methods:Thirty patients with COPD were as the stable COPD group,30 healthy donors were enrolled as control.The expression of plasma TH17 cells was determined by flow cytometry.The levels of plasma interleukin(IL)-17,IL-4 and interferon(IFN)- were measured by ELISA.Results:The expression of TH17 cells in stable COPD group was significantly higher than that in normal group(P〈0.05).ELISA assay showed that the levels of plasma IL-17 and IFN- in stable COPD group were significantly higher than those in normal group(P〈0.05).The level of plasma IL-4 between the two groups had may participate statistical difference(P〉0.05).Conclusions:The expression of TH17 cells is significantly increased in patients with COPD,it participated in the chronic inflammatory process of COPD.
