NUCB2/nesfatin-1-like ir in the gut of zebrafish fed with HDF-P and HFD-C compare to MFD-C. Cross sections of the zebrafish for nesfatin-1-like show higher abundance of nesfatin-1-like cell in HFD-C compared to HFD-P (3 F). For details on methods employed for percentage of positive intestinal epithelial cells calculation, please consult the Materials and Methods section. Values with different superscript letters are significantly different (p < 0.05).

Ghrelin-like ir in the gut of zebrafish fed with HDF-P and HFD-C compare to LFD-C. Ghrelin positive cells did not show changes in the intestine of fish fed a LFD-C (4C) compare to LFD-P (4D) and HFD-C (4A) compare to HFD-P (4B). For details on methods employed for percentage of positive intestinal epithelial cells calculation, please consult the Materials and Methods section. Values with different superscript letters are significantly different (p < 0.05).

Elevated fat content increases lipid droplets, but did not alter intestinal mucosal epithelium in zebrafish fed a HFD, MFD and LFD. TEM micrograph showing large lipid droplets accumulation in the apical epithelium of enterocytes and intraepithelial macrophages in HFD-C fed fish (A). Intact brush border in HFD-C fed fish, (B). Macrophages in MFD-C fed fish in contact with the cell membrane of infiltrated lymphocytes and granulocytes (C). Intraepithelial macrophages with typical features of phagocytic cells in LFD-C fed fish (D). Magnification of intra-epithelium granulocytes in MFD-C fed fish (E).

Lactobacillus rhamnosus did not alter intestinal mucosal epithelium in zebrafish fed a HFD-P, MFD-P and LFD-P. Micrographs showed the absence of damage signs in the intestine of fish fed with diet probiotic enriched (Figs. 6 A-F). Micrograph also showed an intact intestinal mucosal epithelium with intracellular tight junctions epithelial integrity, well organized microvilli and no cell debris in the intestinal lumen of zebrafish fed a HFD-P, MFD-P and LFD-P (Fig. 6 B, D, F). Scale bar: A, C, D ed E = 10 μm, B ed F = 1 μm
