Figure Lengend Snippet: The original values for the selected cytokines were quantitated in serum obtained from healthy nonsmokers (n = 20) and subjects with SCOPD (n = 23) and AECOPD (n = 21) by ELISA (A). To eliminate the mixed effects of inflammatory factors, the authors divided each original value by the arithmetic mean of a classical inflammatory marker, such as TNF-α (B) and IL-17 (C). The data are presented as the mean ± SEM, unless otherwise stated. *p<0.05 and **p<0.01.

Article Snippet: The concentrations of cytokines (TGF-β, IL-10, TNF-α, IL-17 and IL-9) in serum were measured using ELISA kits according to the manufacturer’s protocols (all kits were purchased from Boster Biosciences Co., Wuhan, China).

doi: 10.4049/jimmunol.1102840

Figure Lengend Snippet: A, Naïve CD4+T cells from WT mice were activated with anti-CD3 and anti-CD28 and cultured with IL-4 and anti-IFN-γ (Th2 conditions) or with IL-4, TGF-β and anti-IFN-γ (Th9 conditions). Each day during differentiation, cells were stained for intracellular-phospho-STAT3 and phospho-STAT6. The bar graphs represent percentages of cells (top) and mean fluorescent intensity (MFI, bottom). Data are average ± S.E.M of 6 mice from 3 experiments.B, C. Naïve CD4+T cells from WT and Stat6−/− (top), WT and Stat3CD4−/− (middle), and WT and Parp14−/− mice (bottom) were cultured under Th9 conditions. After 5d cells were harvested and stimulated with PMA and Ionomycin before intracellular staining for cytokines IL-9 and IL-4 was performed (B) or stimulated with anti-CD3 and 24h later cell-free supernatant was collected and IL-9 production was assessed by ELISA (C). Data are representative of 3 experiments with similar results.*, p<0.05. ***, p<0.001.

Article Snippet: Cell free supernatant was collected and the amount of IL-9 was assessed by ELISA using anti-IL-9 capture antibody (D8402E8; BD Biosciences) and biotin-labeled anti-IL-9 (D9302C12; Biolegend) as the secondary antibody.

Figure Lengend Snippet: A-C. WT and Il4−/− naïve CD4+T cells were activated with anti-CD3 and anti-CD28 and cultured under Th9 cell conditions for 48h before being transduced with control or GATA3-expressing retroviruses (A), control or c-Maf expressing retroviruses (B), or control or JunB-expressing retroviruses (C). After 5d in culture cells were stimulated with PMA and Ionomycin for intracellular staining of IL-9 and IL-4. Data are representative of 2-3 independent experiments with similar results.*, p<0.05. **, p<0.01.

Figure Lengend Snippet: A, Naïve CD4+T cells from WT mice were analyzed directly ex vivo (naïve) or cultured under Th1, Th2, Th17, Th9, and Treg cell conditions for 5d. After RNA isolation, quantitative PCR was performed for the indicated genes. Data are representative of 2 experiments with similar results. B, Total cell lysates were prepared from Th1, Th2, and Th9 cells and immunoblot was performed for Runx3, β-actin was used as loading control. C, WT naïve CD4+T cells were activated with anti-CD3 and anti-CD28 and cultured under Th9 cell conditions for 48h before being transduced with control or Runx3-expressing retroviruses and control or T-bet expressing retroviruses. Cells were harvested after 5d in culture and stimulated with PMA and ionomycin before intracellular IL-9 and IL-4 staining. Data are average ± S.D of 2 experiments with 4 mice.
