Autoimmune diseases are characterized by dysregulation and aberrant activation of cells in the immune system. Therefore, restoration of the immune balance represents a promising therapeutic target in autoimmune diseases. Interleukin-2 (IL-2) can promote the expansion and differentiation of different immune cell subsets dose-dependently. At high doses, IL-2 can promote the differentiation and expansion of effector and memory T cells, whereas at low doses, IL-2 can promote the differentiation, survival, and function of regulatory T (T) cells, a CD4 T cell subset that is essential for the maintenance of immune homeostasis and immune tolerance. Therefore, IL-2 exerts immunostimulatory and immunosuppressive effects in autoimmune diseases. The immunoregulatory role of low-dose IL-2 has sparked excitement for the therapeutic exploration of modulating the IL-2-T axis in the context of autoimmune diseases. In this review, we discuss recent advances in the therapeutic potential of IL-2 or IL-2-derived molecules in the treatment of autoimmune diseases.
自身免疫性疾病的特征是免疫系统中的细胞失调和异常激活。因此，恢复免疫平衡是自身免疫性疾病的一个有前途的治疗靶点。白细胞介素-2（IL-2）可以剂量依赖性地促进不同免疫细胞亚群的扩增和分化。高剂量的 IL-2 可以促进效应和记忆 T 细胞的分化和扩增，而低剂量的 IL-2 可以促进调节性 T（T）细胞的分化、存活和功能，调节性 T 细胞是维持免疫稳态和免疫耐受所必需的 CD4 T 细胞亚群。因此，IL-2 在自身免疫性疾病中发挥免疫刺激和免疫抑制作用。低剂量 IL-2 的免疫调节作用激发了人们对调节自身免疫性疾病中 IL-2-T 轴的治疗探索的兴趣。在这篇综述中，我们讨论了 IL-2 或 IL-2 衍生分子在治疗自身免疫性疾病方面的治疗潜力的最新进展。
