Effect of Lactococcus lactis subsp. lactis LM1185 on the mRNA expression of TNF-α and iNOS gene in the RAW 264.7 cells. RAW 264.7 cells (1 × 10⁸ cells/well) were cultured for 24 h in medium with 10 ng/mL LPS (10 ng/mL) L. lactis subsp. lactis LM1185 (1 × 10⁶ cells/mL). A TNF-α and B iNOS relative mRNA expression levels were evaluated by reverse transcription-quantitative polymerase chain reaction. Values are expressed as the mean ± SD of three independent experiments. A, B ^#P < 0.01 vs. control; *P < 0.001 vs. LPS
