Progress of gene-mediated precision immunotherapy in the treatment of acute myeloid leukemia / 中国药科大学学报

@#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.

Combination therapy and drug delivery strategies for treatment of non-alcoholic fatty liver disease / 中国药科大学学报

@#Non-alcoholic fatty liver disease (NAFLD) is a series of chronic liver diseases strongly associated with the metabolic disorder with an increasing rate of worldwide prevalence.Due to its complicated pathogenesis, only Saroglitazar has been approved by Indian Drug Controller General (DCGI) as a PPAR-α/γ dual agonist to treat non-cirrhotic non-alcoholic steatohepatitis.Combination therapy, which can target same or different signaling pathways of NAFLD pathogenesis, has been developed to achieve synergistic therapeutic efficacy.Currently, small-molecule drug combination, RNAi combination therapy, and chemogene therapy are proposed as promising strategies in NAFLD treatment.In addition, designing a smart, safe and effective drug delivery system is key to realizing the druggability, clinical translation and industrialization of small molecule drugs and gene drugs.This review summarizes the research status and delivery system of small-molecule drug combination, RNAi combination therapy, and chemogene therapy, in the hope of providing some novel insight for the treatment of NAFLD.
