摘要
BackgroundThis study is aimed at investigating the frequency of different functional IL-22(+)CD4(+) T cells in Chinese patients with type 2 diabetes mellitus (T2DM). MethodsThe frequency of circulating IFN-+IL-17-IL-22-CD4(+) (Th1), IFN--IL-17A+IL-22-CD4(+) (Th17), and IFN--IL-17A-IL-22(+)CD4(+) (Th22), and other subsets of IL-22(+)CD4(+) T cells in 31 patients with new onset T2DM and 16 healthy controls was characterized by flow cytometry. The levels of serum IL-22, IL-17, IFN-, insulin C-peptide, hemoglobin A1c (HbA1c), fasting plasma glucose, and insulin were examined. ResultsThe frequency of Th1, Th17, Th22, IFN-+IL-17(-)IL-22(+), and IFN--IL-17(+)IL-22(+) CD4(+) T cells and the concentrations of IL-22, but not IL-17 and IFN, in the patients were significantly higher than controls. The percentages of Th22 cells were correlated positively with the frequency of IFN--IL-17(+)IL-22(+)CD4(+) T cells, the values of body mass index (BMI) and homeostatic model assessment insulin resistance (HOMA-IR), and the levels of serum IL-22 in those patients. ConclusionOur data suggest that IL-22(+)CD4(+) T cells may contribute to the early process of T2DM.
