Figure 6: The effect of apamin on macrophage infiltrations in atherosclerotic mice. (a) Immunohistochemistry and (b) immunofluorescence examinations showed that apamin markedly inhibited macrophages infiltration in atherosclerotic mice. Micrographs display macrophages (green), nuclei (blue), and merged images. NC, normal control; Apa, normal control treated with apamin; LPS/Fat, LPS injection and high-fat-dieted mice (atherosclerotic mice); LPS/Fat+Apa, atherosclerotic mice treated with apamin. Scale bars, 50 μm.
