Abstract:
Objective To explore the role of Th17/IL-17 in the pathogenesis of asthma in children.Methods Thirty asthma children (asthma group) and 20 healthy volunteers (control group) were selected as our subjects.Percentage of Th17 cell in peripheral blood mononuclear cell (PBMC) of asthma children was detected by flow cytometry,the level of IL-17 and IgE in plasma were examined by enzyme linked immunosorbent assay.Results Proportion of Th17 cells in PBMC of children in asthma group was (1.83 ± 1.01) %,significantly higher than that in control group ((1.02 ± 0.49) % ; t =3.896 ; P < 0.01).The IL-17 level in control group was (19.11 ± 3.23) ng/L,significant lower than that in asthma group ((34.23 ± 4.88) ng/L;t =6.261 ;P < 0.01)).The Ig E level in asthma group was (399.4 ± 45.1) ng/L,significantly higher than in control group((58.2 ± 19.7) ng/L;t =7.244,P <0.01).The level of IL-17 in plasma had a postive relationship with the proportion of Th17 cells(r =0.882,P <0.01),but not relationship was seen with the level of IgE (r =0.375,P < 0.05).Conclusion Th1 7 cell is associated with asthma development of children,and the reason may due to probably aggravating asthma condition through increasing inflammation secreting IL-17.
