先天模式识别受体(PRRs)对病毒感染的识别,包括膜相关toll样受体(TLR)和细胞质rig -I样受体(RLR),激活信号转导通路的级联反应,导致I型干扰素(IFN)和促炎细胞因子的产生,从而协调病毒的消除。尽管已经证明prr介导的先天免疫在保护病毒免受感染方面起着至关重要的作用,但它偶尔也会导致促炎细胞因子的大量产生,从而导致严重的炎症、血管渗漏和组织损伤。在我们努力鉴定选择性增强prr介导的抗病毒而不是有害炎症反应的小分子时,我们发现了一种化合物RO 90-7501(' 2 ' -(4-氨基苯基)-[2,5 ' -bi- h -苯并咪唑]-5-胺),它可以显著促进TLR3和RLR配体诱导的IFN-β基因表达和抗病毒反应,很可能是通过选择性激活p38丝裂原活化蛋白激酶(MAPK)途径。因此,我们的结果表明,有利于诱导有益抗病毒反应的PRR信号转导途径的药理学调节可能是一种新的治疗策略。
Recognition of virus infection by innate pattern recognition receptors (PRRs), including membrane-associated toll-like receptors (TLR) and cytoplasmic RIG-I-like receptors (RLR), activates cascades of signal transduction pathways leading to production of type I interferons (IFN) and proinflammatory cytokines that orchestrate the elimination of the viruses. Although it has been demonstrated that PRR-mediated innate immunity plays an essential role in defending virus from infection, it also occasionally results in overwhelming production of proinflammatory cytokines that cause severe inflammation, blood vessel leakage and tissue damage. In our efforts to identify small molecules that selectively enhance PRR-mediated antiviral, but not the detrimental inflammatory response, we discovered a compound, RO 90–7501 (‘2’-(4-Aminophenyl)-[2,5′-bi-1H-benzimidazol]-5-amine), that significantly promoted both TLR3 and RLR ligand-induced IFN-β gene expression and antiviral response, most likely via selective activation of p38 mitogen-activated protein kinase (MAPK) pathway. Our results thus imply that pharmacological modulation of PRR signal transduction pathways in favor of the induction of a beneficial antiviral response can be a novel therapeutic strategy.
