Murine spleen cells were stimulated with 1 μg/mL anti-CD3 for 1 d (a) or 1 μg/mL LPS for 2 d (b). Adrenomedullin (ADM) was added to culture medium at the indicated concentrations. Cytokines were measured using a Bio-Plex mouse cytokine multiplex kit. Measurements of IL-17A and TNF-α were performed by conventional ELISA. Cytokine productions with no stimulus were 9.9 ± 1.6 in IL-2, 1.6 ± 0.2 in IL-6, 1.7 ± 0.2 in IL-10, and below the detection limit for the others. N = 3-4. *P < 0.05 versus control by Dunnett test.
