Myeloid differentiation 2 deficiency attenuates AngII-induced arterial vascular oxidative stress, inflammation, and remodeling

MD2 deficiency alleviated Ang II induced vascular remodeling in vivo. (A) Aortic thickening in the mice and aortic tunica media fibrosis was examined by Masson trichrome staining and H&E staining (scale bar = 50 μm). (B) Quantification for staining results in 2A (n = 10; ***pC) Representative immunofluorescence staining images for α-SMA (green) and Vimentin (red) in aortas. Tissues were counterstained with DAPI (blue) (scale bar = 50 μm). (D, E) Quantification for staining results in 2C (n = 10; ***pF) Representative images of COL-3 and PCNA staining of aortas (scale bar = 500 μm; DAB chromogen staining (brown). (G, H) Quantification for staining results in 2F (n = 10; ***pI, J) Expressions of α-SMA, Vimentin and COL-3 in the whole aorta (n = 10; *p
