摘要
共刺激分子作为T细胞激活的第二信号,在免疫应答中起着关键作用。共刺激分子分为正性共刺激分子和负性共刺激分子两类,两者在肿瘤组织中的表达直接影响预后情况。经过放射治疗之后,正性共刺激分子和负性共刺激分子的表达均发生变化,导致肿瘤微环境改变。本文综述了几类常见的共刺激分子在肿瘤放射治疗之后的表达趋势,并寻找出肿瘤放疗协同肿瘤免疫治疗的新型治疗模式。
As a second signal of T cell activation, costimulatory molecules play a key role in the immune response. Costimulatory molecules include positive and negative costimulatory molecules, and the expression of costimulatory molecules in tumor tissues directly affects the prognosis. After radiotherapy, the expression of positive and negative costimulatory molecules will be changed, which can result in the change of tumor microenvironment. In this paper, we review the expression trend of several common costimulatory molecules in the tumor after radiotherapy, and try to explore a new treatment model which combained tumor immunotherapy with radiotherapy.
