Additional file 1. Cg, but not LPS, induced IL-1β production by naive peritoneal macrophages. (A, B) Peritoneal macrophages were stimulated with Cg (300 μg/ml), Lipopolysaccharides (LPS - 1 μg/ml – 4 h) or medium. After treatments the supernatant were collect to quantify the IL-1β and TNF production by Elisa. Data are represent the mean ± SD of four independent experiments compared Control vs Treatments groups to determine the level of statistical significance (*p
