Protective Effect of Iridoid Glycosides of the Leaves of Syringa oblata Lindl. on Dextran Sulfate Sodium-Induced Ulcerative Colitis by Inhibition of the TLR2/4/MyD88/NF-κB Signaling Pathway

Figure 9

Iridoid glycosides reduced mRNA and protein expressions of TLR4 in DSS-induced colitis. The protein levels of TLR4 were analyzed by immunohistochemical staining. The relative mRNA expressions of TLR4 were normalized to GAPDH. Data are presented as the ( per group). ## vs. the normal control group, vs. the DSS-induced colitis group, §§ vs. the IG (20 mg/kg)+DSS group, and ★★ vs. the IG (40 mg/kg)+DSS group.
