Inhibition of Notch1-mediated inflammation by intermedin protects against abdominal aortic aneurysm via PI3K/Akt signaling pathway
Figure 5. NLRP3 inflammasome activation was inhibited by IMD via Notch1 signaling. (A) Immunohistochemistry analysis of the protein expression of ASC in aortas of Control, AngII, AngII+IMD and AngII+DAPT mice. Control, saline infusion; AngII, AngII (1000 ng/kg/min) infusion; AngII+IMD (300 ng/kg/min) infusion; AngII+DAPT (10 mg/kg) gavage for 4 weeks. Scale bar, 500 μm, 100 μm. Boxes and arrows show enlarged areas. (B) Western blot analysis of protein levels of NLRP3, ASC, caspase-1, IL-1β, IL-18 in Raw264.7 macrophage cell line. The cell line was exposed to PBS, AngII (100 nm, 1 h) and DAPT (20 nm, 1 h). (C, D) Quantification of (B). n=3, Data are mean ± SD. *P<0.05 vs. Control. #P<0.05 vs. AngII.
