β-arrestin 2 attenuates lipopolysaccharide-induced liver injury via inhibition of TLR4/NF-κB signaling pathway-mediated inflammation in mice

Figure 2 Expression of inflammatory factors induced by lipopolysaccharide in vivo. qRT-PCR was used to determine relative mRNA levels of IL-1β (A), IL-6 (B), TNF-α (C), and IL-10 (D) in liver tissues; E and F: ELISA was used to determine levels of IL-6 and TNF-α in serum. ^aP < 0.05 vs control group; ^cP < 0.05 vs β-arrestin 2 WT mice.
