Effect of delphinidin on the differentiation of T lymphocytes from non-MetS and MetS patients. Cells isolated from non-MetS (1–2 criteria) and MetS (3, 4 or 5 criteria) patients were stimulated for 24 h with 10−2 g/L of delphinidin (Del), 5 µg/mL of PHA or both. (A) The expression of T-bet, GATA3, RORγt and FOXP3 transcription factors in treated cells was measured by RT-qPCR. Results are normalized with the gene reference and expressed as relative expression compared to PHA group. Data are the mean ± SEM (n = 5–10). The production of IL-2, IFNγ, IL-4, IL-17 and IL-10 was measured in supernatants of treated cells using Magnetic Luminex Screening Assay. (B) Effects of PHA on cytokine production compared to controls cells. (C) The effect of delphinidin on cytokines production induced by PHA in non-MetS and MetS-derived cells. Data are the mean ± SEM (n = 9–11). (D) Negative correlation between delphinidin effect on PHA-induced IL-17 production and number of MetS criteria. *P < 0.05, **P < 0.01 and ***P < 0.001.
