Adoptive immunotherapy with antigen-specific T cells expressing a limited TCR repertoire is a promising approach to fighting various types of cancer and chronic viral infections ; however, the effectiveness of this therapy declines due to exhaustion of the antigen-specific T cells. To overcome this problem, we have explored the potential of induced pluripotent stem(iPS) cell technology and have generated T cell-derived iPS(T-iPS) cells. Furthermore, we have succeeded in redifferentiating T-iPS cells into T lineage cells. As was expected, the invariance of the antigen specificity was evidenced by the fact that the TCR gene rearrangement patterns in the redifferentiated T lineage cells were identical to those in the original T cell. These findings suggest that regeneration of antigen-specific immune systems using iPS cell technology will shed new light on the field of adoptive immunotherapy.
