In addition, liver-infiltrating LKM-1-specific CD4+ T-cell clones have shown a restricted TCR Vβ repertoire [60]. In chronic AIH-bearing C57BL/6– NTx–PD-1À/À mice, effector T cells infiltrated into the liver exhibited clonal TCR Vβ usage [9]. In contrast, in the case of fatal AIH-bearing BALB/c–NTx–PD-1À/À mice, effector T cells infiltrated into the liver showed more abundant clonal TCR Vβ usage [9]. These data suggest that mono- or oligoclonal expansion of infiltrating effector CD4+ T cells in the liver may be relevant to the proliferation of autoreactive CD4+ T cells induced by autoantigen-presenting DCs in the spleen.
