Dose-dependent and time-dependent effects on secretion of IL-13 following stimulation with Ppg and LpA in human adult PBMC. (A) IL-13 secretion induced by Ppg stimulation was dose dependent and significantly higher with 10 μg/ml Ppg than in un-stimulated cells (p = 0.03). (B) IL-13 secretion induced by LpA stimulation was independent of dose. (C) IL-13 secretion of un-stimulated cells (M) and following LpA stimulation was independent of time. IL-13 secretion was higher after 72 h of stimulation with 10 μg/ml Ppg than after 24 and 16 h of stimulation (p < 0.01). (A, B, and C) Cytokine concentrations from supernatants of adult PBMCs were harvested at the indicated times after stimulation with the indicated doses (μg/ml) of Ppg and LpA and measured using ELISA (n = 7).
