类风湿性关节炎(RA)是世界范围内最常见的自身免疫性疾病之一,可导致严重的软骨损伤和残疾。尽管最近在RA治疗方面取得了进展,但在实现早期和有效的治疗干预方面仍然存在局限性。先进的治疗策略的需求很高,基于siRNA的具有基因沉默能力的治疗技术代表了RA治疗的新方法。在这项研究中,我们创建了一个阳离子传递胶束组成的低分子量(LMW)聚乙烯亚胺(PEI)-胆固醇-聚乙二醇(PEG)(LPCE)的小干扰RNA(siRNA)为基础的RA基因治疗。该载体基于LMW PEI并用胆固醇和PEG修饰。通过这两种修饰,LPCE胶束变得多功能,并且其以大于70%的高效率有效地将siRNA递送到巨噬细胞。合成的LPCE具有较强的siRNA保护能力和较高的安全性。通过递送活化B细胞的核因子κ轻链增强子(NF-κB)p65 siRNA,p65 siRNA/LPCE复合物在体外有效地抑制基于巨噬细胞的细胞因子释放。在小鼠模型中,局部施用p65 siRNA/LPCE复合物对RA表现出快速和有效的抗炎作用。根据本研究的结果,我们所制备的功能化LPCE胶束对RA具有潜在的基因治疗意义。
Rheumatoid arthritis (RA) is one of the most common autoimmune diseases worldwide, causing severe cartilage damage and disability. Despite the recent progress made in RA treatment, limitations remain in achieving early and efficient therapeutic intervention. Advanced therapeutic strategies are in high demand, and siRNA-based therapeutic technology with a gene-silencing ability represents a new approach for RA treatment. In this study, we created a cationic delivery micelle consisting of low-molecular-weight (LMW) polyethylenimine (PEI)–cholesterol–polyethylene glycol (PEG) (LPCE) for small interfering RNA (siRNA)-based RA gene therapy. The carrier is based on LMW PEI and modified with cholesterol and PEG. With these two modifications, the LPCE micelle becomes multifunctional, and it efficiently delivered siRNA to macrophages with a high efficiency greater than 70%. The synthesized LPCE exhibits strong siRNA protection ability and high safety. By delivering nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) p65 siRNA, the p65 siRNA/LPCE complex efficiently inhibited macrophage-based cytokine release in vitro. Local administration of the p65 siRNA/LPCE complex exhibited a fast and potent anti-inflammatory effect against RA in a mouse model. According to the results of this study, the functionalized LPCE micelle that we prepared has potential gene therapeutic implications for RA.
