摘要
肿瘤免疫微环境(tumor immune microenvironment,TIME)是一个高度复杂的生态系统,肿瘤细胞与免疫细胞在时间、空间维度动态互作,产生时空异质性(spatiotemporal heterogeneity)。值得注意:肝癌免疫微环境异质性与临床表型显著相关;抗原呈递、趋化因子、免疫代谢等相关机制参与了免疫微环境异质性的时空调控。未来,随着研究工具不断进步、对时空异质性解析逐渐深入,基于个体免疫微环境动态特征,建立个体化免疫治疗(personalized immunotherapy)新策略,将使更多肿瘤患者获益。
TIME(tumor immune microenvironment)is a highly organized ecosystem made of cancer cells and surrounding immune cells.These two components communicate and interact with each other at spatial and temporal levels,resulting in spatiotemporal heterogeneity.It’s noteworthy that spatiotemporal TIME heterogeneity closely correlates with clinically relevant neoplastic phenotypes.And antigen presentation,chemokine programs,and immune metabolism play key roles in the regulation of spatial and temporal TIME heterogeneity.With the application of novel research approaches,spatiotemporal TIME heterogeneity will be further decoded,prompting personalized liver cancer immunotherapy strategies based on distinct spatiotemporal TIME patterns.Advances in spatiotemporal TIME heterogeneity research will ultimately bring benefits to patients in clinical settings.
