BACKGROUND: To examine the steady state of hepatic myeloid-derived suppressor
cells (MDSCs) and the lipid accumulation and inflammation-related changes in
these cells, we analyzed the presence and functions of hepatic MDSCs in the
following two non-alcoholic steatohepatitis (NASH) mouse models. METHODS:
Monosodium glutamate (MSG) model; MSG was subcutaneously injected into neonatal
male C57BL/6J mice that were fed with normal diet up to 18 weeks of age.
Methionine/choline-deficient diet (MCD) model; 16-week-old male C57BL/6J mice
were fed with an MCD for 2 weeks. Those hepatic MDSCs were evaluated by flow
cytometry and immunohistochemically. RESULTS: Both MSG and MCD mice exhibited
greater numbers of hepatic lipid droplets than 18-week-old male control mice.
Hepatocellular ballooning was obvious in MSG, whereas inflammatory cell
infiltration were apparent in MCD mice. CD11b, CD115, and Gr-1-positive hepatic
MDSCs were increased in both models but higher in MCD mice, and demonstrated
higher expression of an M2 macrophage marker CD206 mean fluorescence intensity
(MFI) in MSG compared to MCD mice. Degree of reactive oxygen species production
was evaluated using the DCFDA MFI values, which were significantly elevated in
hepatic MDSCs from MCD mice. MSG mouse livers demonstrated Gr-1 positive cell
accumulation around lipid droplets, mimicking crown-like structures in adipose
tissues. In contrast, hepatic Gr-1 positive cells were primarily located in
inflammatory cell aggregates in MCD mice. CONCLUSIONS: These results suggest that
hepatic fatty changes promote MDSC accumulation, and inflammatory changes induce
phenotypic and functional alteration in hepatic MDSCs in NASH mouse models.
