【摘要】 免疫细胞功能受共抑制受体和共刺激受体的调控。免疫检查点抑制剂在肿瘤治疗中被广泛应用，但其疗效受到免疫抑制性肿瘤微环境的影响。靶向共刺激受体的激动性抗体或其对应的配体等免疫激动性药物能增强免疫系统的抗肿瘤反应，成为新一代肿瘤治疗策略。介绍近年不同类型免疫激动性药物，并综述基于抗体靶向的免疫激动性药物在肿瘤免疫治疗领域中的研究进展，以期为下一代免疫激动性药物的研发提供新思路。更多还原

【Abstract】 Immune cell function is regulated by co-inhibitory and costimulatory receptors. Although immune checkpoint inhibitors are widely utilized in tumor therapy, their efficacy is hampered by the immunosuppressive tumor microenvironment. Immunoagonistic drugs, such as agonistic antibodies or their corresponding ligands targeting costimulatory receptors, have the potential to enhance the immune system’s anti-tumor response and are emerging as a new generation of cancer treatment strategies. This review aims to introduce various types of immunoagonistic drugs developed in recent years and to evaluate the research progress of antibody-targeted immunoagonistic drugs in the field of tumor immunotherapy, in order to provide new insights for the development of the next generation of immunoagonistic drugs.更多还原
