Figure 6.
IL-10, IL-1β, IL-6, and TNF-α secretion by co-cultured Caco-2 (apical side) and PBMCs (basolateral side) under LPS stimulation at baseline (0h) and after 24 h of incubation with sauerkraut brine (SK1 and SK2) or control cell culture medium (CTRL). Bar plots represent median values of median fluorescent intensity (MFI) of the Magpix® signal, and the error bars represent standard deviation (n = 3). Note the different scales on the y-axis. Different superscript letters indicate statistically significant differences within each cytokine.
