β-干扰素(IFN-β)是一种具有强效免疫调节特性的细胞因子,并且已被描述为用于治疗类风湿性关节炎(RA)的有前景的治疗分子。在佐剂性关节炎(AA)大鼠中,IFN-β先前使用腺病毒载体在关节内过表达,作为RA模型。这种效应是强大的,尽管由于所选择的载体而短暂。因此,在临床前开发的背景下,选择了一种优化用于关节内基因转移的递送载体,重组腺相关病毒5型(rAAV 5)。为了发挥最佳效果,蛋白质的产生应该与疾病的进程平行。因此,IFN-β的基因被置于炎症反应性[核因子(NF)-κB]启动子的控制下。在AA大鼠关节内注射rAAV 5构建体后,发现转基因的局部转录和IFN-β蛋白的产生,当表达在NF-κ B应答启动子的控制下时,对爪肿胀产生显著和持续的作用。此外,还观察到对蛋白聚糖消耗和侵蚀的显著有益作用。因此,使用rAAV 5载体的IFN-β的关节内过表达表现出作为治疗RA的创新疗法的潜力。
Beta interferon (IFN-β) is a cytokine with potent immunomodulatory properties and has been described as a promising therapeutic molecule for the treatment of rheumatoid arthritis (RA). IFN-β was previously overexpressed intra-articularly using an adenoviral vector in rats with adjuvant arthritis (AA) as a model of RA. This effect was powerful, albeit transient due to the vector chosen. Therefore, in the context of pre-clinical development, a delivery vector optimized for intra-articular gene transfer, recombinant adeno-associated virus type 5 (rAAV5), was selected. To exert an optimal effect, protein production should parallel the course of the disease. For this reason, the gene for IFN-β was placed under the control of an inflammation-responsive [nuclear factor (NF)-κB] promoter. After intra-articular injection of the rAAV5 constructs in rats with AA, local transcription of the transgene and production of the IFN-β protein was found, leading to a pronounced and sustained effect on paw swelling when the expression was under the control of the NF-κB-responsive promoter. Additionally, a significant beneficial effect was observed on proteoglycan depletion and erosions. Thus, intra-articular overexpression of IFN-β using a rAAV5 vector exhibits potential as an innovative therapy for the treatment of RA.
