For the development of autoimmune hepatitis (AIH), genetic predisposition and environmental triggers are of major importance. Although experimental AIH can be induced in genetically susceptible mice, the low precursor frequency of autoreactive T cells hampers a deeper analysis of liver-specific T cells. Here, we established a system where the model antigen hemagglutinin (HA) is expressed exclusively in hepatocytes of Rosa26-HA mice following administration of a replication deficient adenovirus expressing Cre recombinase (Ad-Cre). Under these conditions, hepatocytes mimic the generation of altered-self neoantigens. To follow autoreactive T cells during AIH, we adoptively transferred HA-­specific Cl4-TCR and 6.5-TCR T cells into Ad-Cre infected ­Rosa26-HA mice. Alternatively, Rosa26-HA mice have been crossed with TCR transgenic mice that were infected with Ad-Cre to break hepatic tolerance and induce the expression of the HA antigen as a hepatic self-antigen. Surprisingly, neither adoptive transfer nor a very high precursor frequency of autoreactive T cells was able to break tolerance in the context of adenoviral infection. The low proliferation of the antigen experienced autoreactive T cells despite the presence of the autoantigen and inflammation points to anergy as a potential tolerance mechanism. This model underscores the crucial importance of genetic susceptibility to break tolerance against hepatic autoantigens.
