成纤维细胞生长因子 20 (FGF20) 是 FGF 家族的旁分泌成员,优先在黑质致密部 (SNpc) 中表达。先前的研究表明,FGF20 可以增强多巴胺能神经元的存活率,这表明 FGF20 可能用于治疗帕金森病 (PD)。然而,细菌重组人FGF20(rhFGF20)的溶解度降低以及缺乏有效的运输rhFGF20穿过血脑屏障(BBB)的策略已经停止了其临床应用。在本研究中,我们检查了将小泛素相关修饰剂 (SUMO) 与 rhFGF20 融合以增强其可溶性表达的效率,并进一步研究了 FUS 引导的 rhFGF20 脂质体跨 BBB 转运的功效。我们还检查了 6-羟基多巴胺损伤的 PD 大鼠模型在接受 2 周的 FUS-脂质体组合治疗后的生物利用度和行为改善。我们的结果表明,与rhFGF20或LIP-FGF20相比,FUS-LIP-rhFGF20治疗可以通过防止SNpc中多巴胺能神经元的损失来显着改善阿朴吗啡诱导的旋转。我们的结果表明,我们的组合方法将有助于克服阻碍目前可用的 rhFGF20 在 PD 治疗中使用的方法的关键挑战。
Fibroblast growth factor-20 (FGF20) is a paracrine member of the FGF family that is preferentially expressed in the substantia nigra pars compacta (SNpc). Previous studies have demonstrated that FGF20 enhances the survival of dopaminergic neurons suggesting the potential use of FGF20 to treat Parkinson’s disease (PD). However, the reduced solubility of the bacterial recombinant human FGF20 (rhFGF20) and the absence of efficient strategies to transport rhFGF20 across the blood–brain barrier (BBB) have halted its clinical application. In the present study, we have examined the efficiency of fuzing a small ubiquitin-related modifier (SUMO) to rhFGF20 to enhance its soluble expression and further investigated the efficacy of FUS-guided, rhFGF20-liposome transport across the BBB. We also examined the bioavailability and behavioral improvement in a 6-hydroxydopamine-lesioned rat model of PD following 2 weeks’ FUS-liposomal combinatorial treatment. Our results showed that, in contrast with rhFGF20 or LIP-FGF20, the FUS-LIP-rhFGF20 treatment could significantly improve the apomorphine-induced rotations by protecting against the loss of dopaminergic neurons in the SNpc. Our Results suggest that our combinatorial method would help overcome key challenges that hinder the currently available methods for the use of rhFGF20 in PD treatment.
