Abstract

The key role of T cells in cancer immunotherapy is well established and is highlighted by the remarkable capacity of Ab-mediated checkpoint blockade to overcome T-cell exhaustion and amplify anti-tumor responses. However, total or partial tumor remission following checkpoint blockade is still limited to only a few types of tumors. Hence, concerted attempts are being made to devise new methods for improving tumor immunity. Currently, much attention is being focused on therapy with IL-2. This cytokine is a powerful growth factor for T cells and optimises their effector functions. When used at therapeutic doses for cancer treatment, however, IL-2 is highly toxic. Nevertheless, recent work has shown that modifying the structure or presentation of IL-2 can reduce toxicity and lead to effective anti-tumor responses in synergy with checkpoint blockade. Here, we review the complex interaction of IL-2 with T cells: first during normal homeostasis, then during responses to pathogens, and finally in anti-tumor responses.

优化用于癌症免疫疗法的 IL-2。
T 细胞在癌症免疫疗法中的关键作用已得到充分证实,Ab 介导的检查点阻断疗法在克服 T 细胞衰竭和增强抗肿瘤反应方面的显著能力也凸显了这一点。然而,检查点阻断后肿瘤的完全或部分缓解仍仅限于少数类型的肿瘤。因此,人们正齐心协力,试图设计出改善肿瘤免疫的新方法。目前,IL-2疗法备受关注。这种细胞因子是一种强大的 T 细胞生长因子,能优化 T 细胞的效应功能。然而,当以治疗剂量用于癌症治疗时,IL-2 具有很强的毒性。然而,最近的研究表明,改变 IL-2 的结构或表达方式可以降低毒性,并与检查点阻断协同作用,产生有效的抗肿瘤反应。在此,我们回顾了 IL-2 与 T 细胞的复杂相互作用:首先是在正常稳态过程中,然后是在对病原体的反应过程中,最后是在抗肿瘤反应过程中。
