MCL oral administration attenuates the progression of atherosclerosis and improves the inflammatory response in ApoE−/− mice. Animals are divided into: ND group, HD group and HD + MCL group. After the experiment, the tissue is harvested and stained with HE, Masson and Oil red O, the serum is collected to analyze the IL-4, IL-10, IL-18, TNF-α, and IL-1β levels. (A) Gross morphology of mouse aortic arch. N = 5; (B–D). Representative images for HE, Masson, and Oil red O stain in aortic roots. N = 5; (E). Oil red O staining of mouse aortas surface. N = 5; (F). IL-1β level in serum. N = 5; (G). IL-18 level in serum. N = 5; (H). TNF-α level in serum. N = 5; (I). IL-4 level in serum. N = 5; (J). IL-10 level in serum. N = 5. ***p < 0.001 vs ND group; ###p < 0.001 vs HD group.
