Fig. 4From: IL-33 ameliorates experimental colitis involving regulation of autophagy of macrophages in miceTreatment with IL-33 ameliorates experimental colitis partly through enhancing autophagy of macrophages located in colon tissues. The colon tissues from mice under indicated treatment were co-stained by Beclin-1 (green) and F4/80 (red) immunofluorescent antibody. DAPI (blue) was used to visualize nuclei. Representative microscopic pictures are shown. Magnification, ×200; Scale bar, 50 μm. The experiments were replicated at least twiceBack to article page
