摘 要：Background:Understanding how the tumor microenvironment is shaped by various factors is important for the development of new therapeutic *** cells often undergo spontaneous apoptotic cell death in tumor microen-vironment,these apoptotic cells are histologically co-localized with immunosup-pressive ***,the mechanism by which tumor cell apoptosis modulates macrophage polarization is not fully *** this study,we aimed to explore the tumor promoting effects of apoptotic tumor cells and the signal pathways ***:Apoptotic cells and macrophages in tumors were detected by immunohistochemical *** analysis was performed with Giemsa *** generated from apoptotic cells were detected by liq-uid chromatography-mass ***-containing lipo-somes were prepared to mimic apoptotic *** expression of protein was determined by real-time PCR,immunohistochemistry enzyme-linked immunosorbent assay and Western *** malignant ascites and subcu-taneous tumor models were designed for in vivo *** mice with specific genes knocked out and inhibitors specific to certain proteins were used for the mechanistic ***:The location and the number of apoptotic cells were correlated with that of macrophages in several types of ***,a lipid molecule generated in apoptotic cells,induced polarization and accumulation of M2-like macrophages in vivo and in ***,sustained administration of phosphoserine promoted tumor growth in the malignant ascites and subcuta-neous tumor *** analyses suggested that phosphoserine induced a M2-like phenotype in macrophages,which was related to the activation of phosphoserine receptors including T-cell immunoglobin mucin 4(TIM4)and the FAK-SRC-STAT3 signaling pathway as well as elevated the expression of the histone demethylase Jumonji domain-containing protein 3(JMJD3).Adminis-tration of
