Hepatic steatosis in Prf−/− mice is dependent on IFN-γ mediated inflammation. Prf−/− and IFN-γR−/− and Prf−/− mice were fed HFD for 10 weeks. (A) Body and liver weight were measured (n = 4–7). (B) Serum levels of ALT (left panel, n = 4–7), cholesterol (middle panel, n = 4–7), and liver TG (right panel) were measured (n = 12–13). (C) Representative images of liver sections stained with H&E (left) and Oil red O (right). (D) TNF-α, IL-6, and IFN-γ levels were detected in liver culture supernatants (n = 4). (E) Representative immunohistochemistry of DAPI (blue), F4/80 (red), iNOS (green), and co-localization (merged image) in liver, and the percentage of M1/M (refers to iNOS+F4/80+cells/ F4/80+ cells) was calculated (right). The data shown in each panel of the figures were collected from a single experiment, and each experiment was repeated for at least three times and rendered consistent results. Means ± SEM, *p < 0.05; **p < 0.01, ***p < 0.001.
