Death receptor-mediated hepatocyte apoptosis is implicated in a wide range of liver diseases including viral and alcoholic hepatitis ischemia/reperfusion injury fulminant hepatic failure cholestatic liver injury as well as malignancy. and immunohistochemical analyses Livers from mice were harvested and after fixation with 4% PFA were embedded in paraffin for further histological evaluation. H&E Oil-Red-O and Sirius Red staining were performed on liver sections. For immunofluorescence analysis liver cryosections of 5?μm were stained with rat anti-mouse CD11b rat anti-mouse F4/80 rat anti-mouse Ly6G and rat anti-mouse Ki-67 (all from BD Biosciences). Slides were fixed in 4% PFA at Cloflubicyne room temperature. Secondary antibody conjugated with FITC Cy3 (Jackson Immunoresearch West Grove PA USA) was used to obtain green and reddish fluorescence signals. Mounting solution made up of DAPI (Vector Laboratories Burlingame CA USA) was used to counterstain the nuclei of hepatocytes. Paraffin tissue sections from your mouse liver were deparaffinized and rehydrated. After antigen retrieval sections were incubated overnight at 4?°C with main biotin-anti-mouse CD45 (clone 30E11; Pharmingen Heidelberg Germany) diluted in TBS buffer made up of 1% BSA and 0.1% Tween 20. Thereafter the sections were incubated with streptavidin ABC-alkaline phosphatase (Vector Laboratories) and color was developed with Vector reddish staining kit (Vector Laboratories) followed by hematoxylin counterstaining. Circulation cytometry analysis Hepatocytes were stained with Annexin V-FITC (BD Biosciences). Immune cells from whole liver were isolated and stained with fluorochrome-conjugated antibodies (CD4-PE CD8-FITC CD45-APC-Cy7 CD11b-PE Ly6G-FITC and F4/80 Biotin) (BD Biosciences). All samples were acquired by circulation cytometry (FACS Canto II; BD Biosciences) and analyzed using the Flowjo software (Ashland OR USA). Statistical analysis Data are expressed as the mean±S.D. Statistical significance was decided via two-way analysis of variance followed by Student’s t-test.
