概括
纳米乳液成功地将乙素 (EN) 输送到淋巴结,通过向炎症和减少疾病严重程度,改善了类风湿性关节炎 (RA) 治疗. 这种有针对性的交付增强了EN EN EN的性能.
科学领域:
- 生物医学工程 生物医学工程
- 纳米技术 纳米技术
- 免疫学 免疫学 免疫学
背景情况:
- 类风湿性关节炎 (RA) 是一种全身性自身免疫性疾病,在全球范围内影响0.5-1%,目前的治疗方法可以控制症状,但不能提供治疗方法.
- 乙南塞普特 (EN) 抑制TNF-α治疗RA,但皮下注射导致全身分布和免疫抑制.
- 排水淋巴结 (LNs) 在RA的发病过程中至关重要,它们是异常免疫反应和炎症性细胞因子产生场所.
研究的目的:
- 开发纳米乳液 (NEs) 封装etanercept (EN) 以有针对性地向RA排水淋巴结 (LNs) 输送.
- 通过局部化分娩来增强EN在治疗类风湿性关节炎 (RA) 的治疗疗效.
主要方法:
- 装有etanercept (EN) 的纳米乳液 (NEs) 使用高压同质化制备.
- 用DSPE-mPEG2000和Ca(OH) 2修改了NE,以提高稳定性和针对性地传递给LN.
- 在体内研究中使用了原诱导关节炎 (CIA) 鼠标模型来评估LN向和治疗效果.
主要成果:
- 纳米乳液封装没有影响乙素 (EN) 的生物活性.
- 在CIA小鼠模型中,NE/EN证明了有效向 inguinal 淋巴结和显著的抗炎作用.
- 与免费EN相比,使用NE/EN治疗显著减少了脚胀,关节炎得分和促炎细胞因子 (TNF-α,IL-1β).
结论:
- 纳米乳液封装的埃坦塞普特 (NEs/EN) 显著提高了类风湿性关节炎 (RA) 的治疗效果.
- 这种有针对性的输送方法为埃坦塞普特在RA治疗中的更广泛的临床应用提供了基础.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
173
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
195
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
