Adhesion and immunomodulatory effects of Bifidobacterium lactis HN019 on intestinal epithelial cells INT-407

Figure 5 Bacteria modulate IL-8 secretion at baseline. B: Bifidobacterium lactis HN019; BK: Heat-killed B. lactis HN019; SK: Heat-killed Salmonella typhimurium ATCC 14028; LPS: Lipopolysaccharide (10 ng/mL); BLPS: Co-incubation with B. lactis HN019 and LPS; LPS-B: Treated with B. lactis HN019 after pretreatment with LPS for 2 h; B-LPS: Treated with LPS after pretreatment with B. lactis HN019 for 2 h. The data are expressed as pg/mL and represent the mean ± SE. ^aP < 0.05, ^bP < 0.01 vs untreated monolayers.
