Fig. 2. Effects of heat-killed LAB strains on mRNA expression of proinflammatory factors and proinflammatory cytokines in LPS-induced RAW 264.7 cells. (A) iNOS, (B) COX-2, (C) IL-1β, (D) IL-6, (E) TNF-α. NC, negative control without LPS; PC, positive control with LPS; LGG, L. rhamnosus GG; 14917, L. plantarum ATCC 14917; 15122, L. plantarum KU15122. Data are presented as mean ± standard deviation of triplicate experiments. Different letters on error bars represent significant differences (p < 0.05).
