[Advances in Allogeneic Chimeric Antigen Receptor T Cells]

Autologous chimeric antigen receptor(CAR)T-cell therapy has improved the prognosis of hematological malignancies.Nevertheless,allogeneic CAR-T cells have potential advantages over the autologous approach available on the market.However,allogeneic CAR-T cells may cause life-threatening graft-versus-host disease(GVHD)or be rapidly eliminated by the host immune system.In this review,we analyze the different sources of T cells for optimal allogeneic CAR-T cell therapy,describe the different approaches,and introduce the gene editing measures to produce allogeneic CAR-T cells with limited potential for GVHD and improved anti-tumor effect.
