Lipopolysaccharide stimulates and EISO suppresses sentinel cytokines/chemokines production by DF (open bar), BEAS-2B (filled bar), A549 (hatched bar), and THP-1 cells (double hatched bar). Cells were treated with vehicle (0), LPS (1 μg/ml) or LPS + EISO (0.001 or 0.002%). Accumulation of TNF-α; 4 h (A), MCP-1 (B), IL-8 (C), and IL-6 (D) at 24 h was determined from conditioned media by ELISA. Cytokine/chemokine accumulation was compared with levels in LPS-stimulated samples, expressed as pg/ml. Data are mean ± SEM (n = 4). p < 0.05, ∗∗p < 0.01, and ∗∗∗p < 0.001 versus control; p < 0.05, ††p < 0.01, †††p < 0.001 versus LPS-stimulated cells.
