Dynamic changes in cellular FPN with intracellular bacteria. (A) Confocal images of FPN co-localized with BL21 over time in macrophages. DAPI-stained cell nucleus. Green fluorescence is BL21. Ferroportin antibody-stained FPN. Scale bar = 5 µm. (B) Co-localization of FPN with bacteria by immunoelectron microscopy and colloidal gold labeling. Scale bar = 200 nm (C) Knockdown efficiency of FPN by immunoblotting. (D-E) Bactericidal efficiency of macrophages after FPN knockdown. (F) Intracellular bactericidal effects of hepcidin pre-treatment. (G) Intracellular bactericidal effects of hepcidin post-treatment. n = 3, ns = not significant, **p < 0.01, ***p < 0.001, ****p < 0.0001.
