肿瘤相关中性粒细胞的研究进展

摘要

Tumor growth depends on the tumor microenvironment(TME).Tumor-associated neutrophils(TANs)are important inflammatory cells in TME.TANs are divided into"N1"type with anti-tumor effect and"N2"type of tumor-promoting effect.Therefore,TANs have both beneficial and harmful aspects of the body.A large number of studies have been shown that TANs affect tumor formation,metastasis,angiogenesis and immune response,regulated by the secretion of cytokines and chemokines.This review will summarize the biological characteristics of TANs,and tumor development,prognosis and treatment of tumor as well as research progress of the relationship between TANs and tumor.%肿瘤生长依赖肿瘤微环境,肿瘤相关中性粒细胞(TANs)是肿瘤微环境中的一种重要炎症细胞.TANs分为具有抗肿瘤效应的"N1"型和促肿瘤效应的"N2"型.因此,TANs具有对机体有利和有害的两面性.大量研究表明,TANs通过分泌细胞因子和化学因子等,影响肿瘤的生成、转移、血管生成与免疫调节.本文将从TANs的生物学特性和TANs与肿瘤发生发展、预后及治疗等方面,综述TANs和肿瘤关系的研究进展.
