基因介导的精准免疫疗法在急性髓系白血病治疗中的进展OA北大核心CSTPCD

Acute myeloid leukemia(AML)is a disease caused by abnormal cloning of hematopoietic stem cells in the bone marrow,which leads to accumulation of a large number of abnormally differentiated myeloid cells.It is difficult to cure by traditional treatment.The successful application of chimeric antigen receptor T cell(CAR-T)immunotherapy indicates that the treatment of hematological tumors has entered a new stage of precision immunotherapy.However,CAR-T immunotherapy has been found to have many problems in clinical applications,including long treatment cycle,expensive prices,off-target effects,cytokine release syndrome,etc.Therefore,it is necessary to expand the application of CAR or adopt improved measures to enhance the therapeutic effect.This article reviews the new strategies for genetic engineering modification of CAR immune cells and the research progress and application of in situ programming to generate CAR-T,and besides,briefly introduces the new methods about the delivery of gene drugs in vivo,aiming to provide new ideas and theoretical basis for expanding and improving the application of precision immunotherapy in AML.
