The cells were surface stained with anti-CD3+ and anti-CD4+ antibodies or anti-CD3+ and anti-CD8+ and analyzed by flow cytometry (P < 0.001). Immunofluorescence analysis and histological changes in the livers of recipient mice Immunofluoresence analysis of the liver sections of the transgenic mice showed infiltration of high number of the CFSE labeled cells, when they received transfer from Selleckchem LY411575 immunized mice (Figure 9a). H&E staining of the liver sections for the same group of recipient mice showed infiltration of lymphocytes beside
the histological changes, LDN-193189 such as steatosis, due to the expression of transgenes (Figure 9b). Interestingly, the infiltrated cells were concentrated in the areas where there was steatosis. On the other hand, the transgenic mice receiving cells from non-immunized donors showed few CFSE labeled cells on the liver sections and no cell infiltration was observed in the H&E stained liver section (Figure 10a, b). The non-transgenic mice showed no histological changes and no infiltration of CFSE labeled cells, whether they received donor cells from immunized (Figure 9c,
d) or non-immunized mice (Figure 10c, d). Thus, repetitive transfer of splenocytes from HCV immunized mice into HCV transgenic mice may be needed in order to increase inflammation in the liver.

A) Immunofluorescent analysis of frozen liver sections (5 μm thick) of a transgenic mouse showing CFSE labeled cells scattered over all the liver section. The fluorescent cells are indicated by arrows. B) H&E stained liver section of transgenic mouse showing steatosis. There is infiltration
of lymphocytes in the liver which is concentrated close to hepatic steatosis (indicated by arrows). C) Immunofluorescence analysis of frozen liver sections (5 μm thick) of non-transgenic mouse showing no Etofibrate CFSE labeled cells over the liver section. D) H&E staining of liver section of non-transgenic mouse showing normal histology of the liver and no lymphocyte infiltration. Scale bar = 50 μm.
