中性粒细胞是固有免疫应答中重要的效应细胞之一,是机体抵抗病原体入侵的第一道防线.随着研究的不断进展,人们意识到中性粒细胞不仅参与了炎症反应和组织损伤修复,浸润肿瘤组织的中性粒细胞还可以根据不同的肿瘤免疫微环境(tumor microenvironment,TME)特征发挥抗肿瘤或促肿瘤的作用.不同功能的中性粒细胞可能具有不同的表型,且具有一定的可塑性.该文将从中性粒细胞的生物学特征谈起,对TME中不同功能的中性粒细胞的表型、免疫抑制性中性粒细胞发挥功能的可能机制以及中性粒细胞在肿瘤研究中的临床应用加以综述.
Research progress on the role of neutrophils in the tumor microenvironment
Neutrophils are one of the most important effector cells in innate immunity and the defense at the frontline against in-vading pathogens.With the continuous advances,people have realized that neutrophils not only participate in the inflammatory response and tissue damage repair,tumor-associated neutrophils also act as anti- or pro-tumorigenic factors depending on spe-cific tumor microenvironment(TME)status.Neutrophils with different functions may have different phenotypes and also some plasticity.This review begins with the biological properties of neutrophils,and then summarizes the diverse phenotypes of neu-trophils with different functions in the TME,the possible mechanisms of immunosuppressive neutrophils regulating tumor im-munity,and the clinical application of neutrophils in cancer research.
