概括
塔克罗利木斯 (TAC) 增加了内皮细胞的炎症. 西利马林 (SM) 有效地减少了TAC引起的炎症,这表明它有可能预防与移植有关的心血管问题.
科学领域:
- 内分泌学
- 免疫学
- 心血管研究
背景情况:
- 塔克罗利木斯 (TAC) 对移植患者至关重要,但会引起心血管毒性,如内皮功能障碍.
- 来自乳的西里马林 (SM) 具有已知的抗氧化和抗炎性质.
研究的目的:
- 研究TAC对人类静脉内皮细胞 (HUVEC) 的促炎作用.
- 确定SM是否可以减轻HUVEC中TAC诱导的炎症.
主要方法:
- 用TAC (20微克/毫升) 处理HUVEC以建立炎症模型.
- 通过西部抹杀测量了促炎媒介 (IL- 1β,TNF-α,COX- 2).
- 评估了SM (50微克/毫升) 的同时治疗对TAC诱导的炎症的影响.
主要成果:
- 在HUVEC中,TAC显著增加了IL-1β,TNF-α和COX-2的表达.
- 与SM同时治疗明显抑制了TAC诱导的这些炎症标志物的上调.
结论:
- 在HUVEC中直接诱导炎症表型.
- 在实验室中,SM有效地对抗TAC引起的内皮炎症.
- 它可能是减少TAC相关的血管炎症和心血管并发症的潜在治疗剂.

Drugs for Treatment of Ulcerative Colitis in IBD
721
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
780
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...
