Effects of Caco-2 cell pretreatment with anti-TLR antibodies on nitric oxide (NO) production in RAW264.7 cells.
Expression of the IL-8 mRNA in RAW264.7 cells was measured by quantitative RT-PCR as described in the materials and methods section. Values represent the mean ± SE (n = 3). Significant differences were observed between the
sample-treated group and the control group (**p<0.01; *p<0.05). NO production after treatment with (a) the EPS of L. delbrueckii TU-1, (b) the EPS of L. plantarum KM-9, (c) UV-killed
L. delbrueckii TU-1cells, (d) UV-killed L. plantarum KM-9 cells, (e) IL-8 mRNA expression after treatment with LPS and Pam3Csk4. Different letters (a, b and c) indicate significant
differences between groups (p<0.05).
