SCI ADV:AAV基因疗法可解决骨关节炎和肥胖问题

2020-05-18 MedSci原创 MedSci原创

肥胖相关的炎症和肌肉功能的丧失在骨关节炎(OA)的发展中起着关键作用;因此,针对肌肉组织的治疗可能可以为恢复与肥胖相关的代谢和生物力学功能障碍提供新的方法。

肥胖相关的炎症和肌肉功能的丧失在骨关节炎(OA)的发展中起着关键作用;因此,针对肌肉组织的治疗可能可以为恢复与肥胖相关的代谢和生物力学功能障碍提供新的方法。

Follistatin (FST),一种能结合肌球蛋白和激活素的蛋白质,可能具有增强肌肉形成的潜力,同时抑制炎症。

因此,研究人员提出假设,腺相关病毒9(AAV9)递送FST可增强肌肉形成,减轻高脂肪饮食引起的小鼠代谢性炎症和膝关节骨关节炎。

实验证明,在全身和关节滑膜液中,AAV介导的FST递送可以减少肥胖诱导的炎症性脂肪因子和细胞因子。无论饮食情况如何,接受FST基因治疗的小鼠均可免受创伤后OA和关节损伤诱导的骨重塑。

这些研究结果表明,FST基因治疗可以为肥胖症中损伤诱导的OA和代谢性炎症提供多因素治疗方法。
