聚(ADP-核糖)聚合酶-1 (PARP-1) 合成 ADP 核糖聚合物并将其转移至靶蛋白,并调节 DNA 修复和基因组完整性维护。 PARP-1 在炎症反应的进展中也起着至关重要的作用,其抑制作用可以在多种炎症性疾病模型中提供保护。在这里,我们研究了选择性 PARP-1 抑制剂对实验性关节炎的影响。用 5-氨基异喹啉酮 (AIQ) 抑制 PARP-1 可显着降低胶原诱导的关节炎的发生率和严重程度,完全消除关节肿胀以及软骨和骨骼的破坏。 AIQ 的治疗效果与疾病的两种有害成分(即 Th1 驱动的自身免疫和炎症反应)的显着减少有关。 AIQ 下调各种炎症细胞因子和趋化因子的产生,减少抗原特异性 Th1 细胞的扩增,并诱导抗炎细胞因子 IL-10 的产生。我们的结果提供了 PARP-1 对关节炎进展贡献的证据,并将该蛋白确定为治疗类风湿关节炎的潜在治疗靶点。
Poly(ADP-ribose) polymerase-1 (PARP-1) synthesizes and transfers ADP ribose polymers to target proteins, and regulates DNA repair and genomic integrity maintenance. PARP-1 also plays a crucial role in the progression of the inflammatory response, and its inhibition confers protection in several models of inflammatory disorders. Here, we investigate the impact of a selective PARP-1 inhibitor in experimental arthritis. PARP-1 inhibition with 5-aminoisoquinolinone (AIQ) significantly reduces incidence and severity of established collagen-induced arthritis, completely abrogating joint swelling and destruction of cartilage and bone. The therapeutic effect of AIQ is associated with a striking reduction of the two deleterious components of the disease, i.e. the Th1-driven autoimmune and inflammatory responses. AIQ downregulates the production of various inflammatory cytokines and chemokines, decreases the antigen-specific Th1-cell expansion, and induces the production of the anti-inflammatory cytokine IL-10. Our results provide evidence of the contribution of PARP-1 to the progression of arthritis and identify this protein as a potential therapeutic target for the treatment of rheumatoid arthritis.
