Figure Lengend Snippet: Fluorescence images and quantification of nanoparticle uptake in TNFα-activated ECs under the following conditions: (A) VCAM1 blockade, (B) β1-integrin blockade on nanoparticles, and (C) CPZ treatment. Red: IA@MoNP, MoNP, or bare NP; blue: DAPI-stained nuclei. Scale bar = 50 μm. (A–B) *p < 0.05 vs. IgG antibody; # p < 0.05 vs. MoNP. (C) *p < 0.05 vs. control ECs; # p < 0.05 vs. bare NP. Data are presented as mean ± SD from n = 3 independent experiments.

Article Snippet: Membrane proteins were assessed by Western blot using antibodies against CD11b (Cell Signaling #17800, 1:1000), Na + /K + ATPase (Cell Signaling #3010, 1:1000), α4-integrin (Invitrogen #PA5-20599, 1:1000), and β1-integrin (Cell Signaling #4706S, 1:1000).
