Cytotoxicity of Lactococcus lactis subsp. lactis LM1185 on RAW 264.7 cells and Effect of Lactococcus lactis subsp. lactis LM1185 on NO production in the RAW 264.7 cells. A Cytotoxicity of Lactococcus lactis subsp. lactis LM1185 on RAW 264.7 cells. Raw 264.7 cells (5 × 104 cells/well) were treated with different cell number of L. lactis subsp. lactis LM1185. The results showed that all MOI of L. lactis subsp. lactis LM1185 had no cytotoxicity on RAW 264.7 cells. Data are presented as mean ± SD of three independent experiments. Noted asterisks indicate statistical significance (*P < 0.05, **P < 0.01). B Effect of Lactococcus lactis subsp. lactis LM1185 on NO production in the RAW 264.7 cells. RAW 264.7 cells were cultured with 5 × 105 cells/well. RAW 264.7 cells treated with 1 μg/mL of LPS or L. lactis subsp. lactis LM1185. When RAW 264.7 cells treated with 5 × 107 cells of L. lactis subsp. lactis LM1185, the highest NO production was detected. Asterisks indicate statistical significance (*P < 0.05, *** P < 0.001)
