Anti-inflammatory activity of probiotic Bifidobacterium: Enhancement of IL-10 production in peripheral blood mononuclear cells from ulcerative colitis patients and inhibition of IL-8 secretion in HT-29 cells

Figure 7 Effects of probiotic DNAs on IL-8 production in HT-29 cells. HT-29 cells were stimulated with TNF-α in the absence or presence of various concentrations of probiotic DNA without (A) or with DNase treatment (B). The inhibitory effect on IL-8 secretion was determined as described in Figure 2. ^aP < 0.05, ^bP < 0.01 vs control.
