Interleukin-1 superfamily of cytokines (IL-1, IL-18, IL-33) play key roles in inflammation and regulating immunity. The mechanisms of agonism and antagonism in the IL-1 superfamily have been pursued by structural biologists for nearly 20 years. New insights into these mechanisms were recently provided by the crystal structures of the ternary complexes of IL-1β and its receptors. We will review here the structural biology related to receptor recognition by IL-1 superfamily cytokines and the regulation of its cytokine activities by antagonists.
白细胞介素-1 超家族细胞因子(IL-1、IL-18、IL-33)在炎症和免疫调节中发挥关键作用。结构生物学家近 20 年来一直在研究 IL-1 超家族中激动剂和拮抗剂的作用机制。最近,IL-1β及其受体的三元复合物晶体结构提供了对这些机制的新见解。我们将在这里回顾与白细胞介素-1 超家族细胞因子的受体识别以及拮抗剂对其细胞因子活性的调节相关的结构生物学。
