放射性核素靶向治疗的免疫学研究进展

Advances in Immunological Studies of Targeted Radionuclide Therapy

放射治疗对健康细胞的杀伤作用,促成放射性核素靶向治疗的产生,有效减少对周边正常细胞的损伤。目前,α、β放射性核素是靶向治疗的研究热点。众多临床前和临床研究表明,放射治疗不仅具有局部抗肿瘤效果,还通过触发机体免疫反应发挥全身抗肿瘤作用。该文详细描述了常用放射性核素的特性和临床应用,探讨辐射触发机体免疫反应的机制以及放射治疗、放射性核素靶向治疗与免疫疗法联合使用的相关研究。

The killing effect of radiation therapy on healthy cells has led to the creation of targeted radionuclide therapy,which effectively reduces the damage to surrounding normal cells.At present,alpha(α)and beta(β)radionuclides are the research hotspots of targeted therapy.Numerous preclinical and clinical studies have shown that radiation therapy not only has local anti-tumor effects,but also exerts systemic anti-tumor effects by triggering the body's immune response.This paper describes in detail the characteristics and clinical applications of commonly used radionuclides,and discusses the mechanism of radiation-triggered body immune response as well as the related research on the combined use of radiation therapy,targeted radionuclide therapy and immunotherapy.
