IL-12家族的细胞因子显示出结构相似性,但在免疫系统中具有不同的功能。该细胞因子家族的突出成员是促炎细胞因子IL-12和IL-23。这两种细胞因子共享细胞因子亚基和受体链,但在自身免疫性疾病、癌症和感染中具有不同的功能。因此,关于受体复合物形成的结构知识对于开发预防和/或抑制细胞因子:受体相互作用的新治疗策略是必不可少的。此外,可以靶向细胞内信号传导级联以抑制精氨酸介导的作用。单核苷酸多态性可导致氨基酸序列的改变,从而影响蛋白质功能或蛋白质-蛋白质相互作用。为了理解IL-12和IL-23的生物学并建立有效的靶向策略,关于细胞因子和各自受体的结构知识是至关重要的。一种高效的治疗方法可能是针对细胞外细胞因子:受体组装和细胞内信号通路的不同药物的组合。
Cytokines of the IL-12 family show structural similarities but have distinct functions in the immune system. Prominent members of this cytokine family are the pro-inflammatory cytokines IL-12 and IL-23. These two cytokines share cytokine subunits and receptor chains but have different functions in autoimmune diseases, cancer and infections. Accordingly, structural knowledge about receptor complex formation is essential for the development of new therapeutic strategies preventing and/or inhibiting cytokine:receptor interaction. In addition, intracellular signaling cascades can be targeted to inhibit cytokine-mediated effects. Single nucleotide polymorphisms can lead to alteration in the amino acid sequence and thereby influencing protein functions or protein–protein interactions. To understand the biology of IL-12 and IL-23 and to establish efficient targeting strategies structural knowledge about cytokines and respective receptors is crucial. A highly efficient therapy might be a combination of different drugs targeting extracellular cytokine:receptor assembly and intracellular signaling pathways.
