Regulation of myeloid-derived suppressor cells by prostaglandin E2 in tumor microenvironment / 国际肿瘤学杂志

ABSTRACT

Myeloid-derived suppressor cells (MDSCs),a heterogeneous population of immature myeloid cells,play an important role in immune tolerance and immune suppression.In recent years,more and more research results show that the prostaglandin E2 (PGE2) has an inseparable relationship with MDSCs,and PGE2 through its relevant receptors,regulating signal transducer and activator of transcription 3 (STAT3) and protein kinase A cell signaling pathways and secretion cytokines in tumor microenvironment,affects the development,differentiation and function of MDSCs.
