[Development of antigen-receptor modified allogeneic T cell from iPS cells for cancer immunotherapy].

The efficacy of T-cell therapy depends on the maintenance of antigen specificity, memory phenotype, longterm viability, and proliferative capacity of T cells in vivo. Personalized autologous T-cell therapies pose a few manufacturing challenges, in terms of quality, and supply stability. Recently, it has become possible to derive CD8 killer T cells from induced pluripotent stem cells (iPSCs) and develop CAR-CD8 killer T cells from allogeneic iPSCs. This article reviews CD8 killer T-cell induction from iPSCs, attempts to enhance process safety and reliability, and discusses the use of gene-editing technology for reducing allogeneic antigenicity.
