Also, 2 days post-infection, the expression of pro-inflammatory cytokines in BALF, such as tumor necrosis factor-α (TNF-α), was significantly higher in the CBM 588 (GPR120 KO) group than in that of the CBM 588 group, whereas the expression of anti-inflammatory cytokine IL-10 was significantly reduced (Figure 3H). This evidence concerns the gene TNF and infection.
