Secretion of IL-13 and IFN-γ by isolated murine spleen cells. Secretion of (A) IL-13 and (B) IFN-γ by isolated murine spleen cells was higher after stimulation with Ppg compared with cells stimulated with LpA or LPS and unstimulated cells (M) (p < 0.001). IFN-γ secretion after stimulation with LpA and LPS was increased compared with secretion by un-stimulated cells (M) (p < 0.01). (C) Lymphocyte proliferation was intact following stimulation with Ppg, LpA, and LPS. (A, B, and C) Cytokine concentrations from supernatants of spleen cells harvested at 44 h after stimulation with 10 μg/ml Ppg, 100 μg/ml LpA, and 10 μg/ml LPS were measured using ELISA. Lymphocyte proliferation was determined following stimulation with the indicated doses of Ppg, LpA, and LPS for 44 h by 3H-thymidine uptake, as described in Materials and Methods (n = 6 mice per group).
