Figure 6: IL-10 production of peritoneal macrophages from knockout mice. Effects of different concentrations of L. casei CRL 431 on the production of IL-10 of peritoneal macrophages from wild type C57BL/6 (black bar), TLR2 -/- C57BL/6 (grey bar), TLR4-/- C57BL/6 (dark-grey bar), and MyD88-/- C57BL/6 (lightgrey bar) mice. a,b,c,dMeans values for peritoneal macrophages without a common letter differ significantly (P<0.05). The error bars indicate standard deviations.
