Solid tumors exhibit a very limited response to immunotherapy.Consequently,effectively enhancing the therapeutic efficacy of tumor immunotherapy has emerged as a critical challenge and problem that urgently needs to be addressed in tumor immunotherapy.The chemotaxis and recruitment of myeloid-derived suppressor cells(MDSCs)and the tumor immune evasionmechanisms mediated by them are one of the core factors that significantly restrict the efficacy of immunotherapy for solid tumors.In this review,we discuss the origins and phenotypic characteristics of MDSCs,the specific mechanisms by which they mediate tumor immune evasion,as well as current targeted therapeuticstrategies for MDSCs and the latest research progress in combining MDSC-targeted therapy with tumor immunotherapy.Furthermore,we have systematically analyzed the key challenges faced by the combination of MDSC-targeted and immunotherapy strategies,and accordingly proposed a precise targeting strategyfor MDSCs.This strategy aims to precisely activate anti-tumor immune responses,providing more personalized and efficienttreatment options for cancer patients,thereby opening a new era in tumor immunotherapy and contributing to the innovation anddevelopment of cancer treatment strategies.
CCAAT增强子结合蛋白A(CEBPA)是调节血液发育过程中髓系分化和造血干祖细胞活性的关键转录因子之一。CEBPA基因突变常见于急性髓系白血病(AML)中,最近研究表明CEBPA bZIP框内单位点和经典双等位基因突变AML患者均具有类似的临床特征,已被单独划分为AML亚群。CEBPA bZIP框内突变而非传统的双等位CEBPA基因突变成为AML良好预后的分子指标,表明其在AML疾病进展和治疗预后中的重要性和特殊性。本文将从CEBPA蛋白在血液系统中的功能、CEBPA bZIP框内突变AML的临床特征与分子作用机制、以及伴CEBPA突变AML的治疗现状等方面进行综述,为进一步研究CEBPA bZIP框内突变在AML中的致病性和精准治疗新药物开发提供参考。
CAAT enhancer-binding protein A(CEBPA)is one of the key transcription factors regulating myeloid differentiation and hematopoietic stem/progenitor cell maintenance during hematopoiesis.CEBPA gene mutations are commonly found in acute myeloid leukemia(AML).Recent studies have demonstrated that AML patients haboring single CEBPA bZIP in-frame mutations or classical bi-allelic CEBPA mutations show similar clinical features and it has been individually classified as AML subgroup.Additionally,it is CEBPA bZIP in-frame mutations rather than the traditional biallelic CEBPA mutations that have emerged as a molecular indicator of favorable prognosis for clinical AML management,suggesting its importance and specificity in AML disease progression and therapeutic prognosis.Here,we reviewed serval aspects including the hematopoietic function of CEBPA protein,the clinical features and molecular mechanisms of AML with CEBPA bZIP in-frame mutations,and the current status of the treatment of AML with CEBPA mutations,which will provide a reference for further study of the pathogenicity of CEBPA bZIP in-frame mutations in AML and the development of new drugs for precision therapy.
