We previously studied transgenic mice that express HCV Core Envelope 1 and Envelope 2 proteins predominantly in the liver resulting in steatosis liver and lymphoid tumors and hepatocellular carcinoma. Herein the immune-mediated cell response to hepatitis C antigens was evaluated by adoptive transfers of carboxyfluorescein succinimidyl ester CFSE labelled splenocytes from HCV immunized mice into HCV transgenic mice. Results In comparison to non-transgenic mice there was a significant decrease in the percentage of CFSE-labeled CD4 and CD8 T cells in transgenic mouse peripheral blood receiving adoptive transfers from immunized donors. Moreover the percentage of CFSE-labeled CD4 and CD8 T cells were significantly higher in the spleen of transgenic and non-transgenic mice when they received splenocytes from non-immunized than from immunized mice. On the other hand the percentages of CD4 and CD8 T cells in the non-transgenic recipient mouse lymph nodes were significantly higher than the transgenic mice when they received the adoptive transfer from immunized donors. Interestingly livers of transgenic mice that received transfers from immunized mice had a significantly higher percentage of CFSE labeled T cells than livers of non-transgenic mice receiving non-immunized transfers. Conclusions These results suggest that the T cells from HCV immunized mice recognize the HCV proteins in the liver of the transgenic mouse model and homed
