Effect of Scb and βGM on IL6 and CXCL8 secretion induced by ETEC. Cytokine IL6 (A) and chemokine CXCL8 (B) concentration in supernatants from IPI-2I cells (1 × 106 cells/well) co-cultured for 24 h with ETEC (1 × 107 CFU/well) is decreased by Scb (3 yeast/cell) or βGM (10 μg/mL). Data were presented as mean ± S.D (n = 6). Data are representative of 3 independent experiments. Means with different superscripts (a, b, c, d) are significantly different (p < 0.05).
