Determination of pro-inflammatory cytokines in LPS–Pepsin-ISP4h-1P-costimulated RAW264.7 macrophage cells. A dosage effect of Pepsin-ISPH4h-1P with 1 ppm LPS co-stimulation on IL-6 (gray column) and IL-10 (white column) productions. B dosage effect of Pepsin-ISPH4h-1P with 1 ppm LPS co-stimulation on IL-6/IL-10 ratio. Bars represent mean ± standard deviation (SD; n = 3). Mean with different letters are significantly different (p < 0.05) by Duncan’s multiple range test
