低剂量IL-2给药可抑制小鼠和人类不需要的免疫应答,从而证明IL-2治疗自身免疫性疾病的潜力。增加的T细胞活性是低剂量IL-2免疫疗法诱导免疫抑制的潜在机制之一。此外,最近的数据表明,IL-2可能有助于防止不必要的自身反应性反应,通过防止T-滤泡辅助细胞的发展,CD 4 + T细胞亚群,扩大自身免疫性疾病患者和促进长期效应B细胞反应。在这里,我们讨论了低剂量IL-2给药的临床益处的机制,重点是这种细胞因子在促进Treg介导的抑制和防止自身反应性T滤泡辅助细胞反应中的作用。
Low-dose IL-2 administration suppresses unwanted immune responses in mice and humans, thus evidencing the potential of IL-2 to treat autoimmune disorders. Increased Tregs activity is one of the potential mechanisms by which low-dose IL-2 immunotherapy induces immunosuppression. In addition, recent data indicate that IL-2 may contribute to prevent unwanted self-reactive responses by preventing the developing of T-follicular helper cells, a CD4+ T-cell subset that expands in autoimmune disease patients and promotes long-term effector B-cell responses. Here we discuss the mechanisms underlying the clinical benefits of low-dose IL-2 administration, focusing on the role of this cytokine in promoting Treg-mediated suppression and preventing self-reactive T-follicular helper cell responses.
