EPs® 7630 induces IL-22 secretion by different CD4⁺ memory T cell subsets. a–c Human PBMCs were stimulated or not (solvent control) with 10 μg/ml EPs® 7630 for 72 h as indicated. Afterwards, an IL-22-specific secretion assay and surface marker staining was performed followed by flow cytometry–based analysis. a Schematic overview of the experimental setting of IL-22-specific secretion assay. b Data from one representative out of three independent experiments are given. c Data from 3 independent experiments are given as mean ± SEM
