概括
催化剂通过将巨细胞从M1转移到M2来减少炎症. 这涉及Sirtuin5 (SIRT5) 调节谷氨酸脱酶1 (GLUD1) 和酸盐/α-酸酸盐比率.
科学领域:
- 免疫学 免疫学 免疫学
- 传统中国医药 传统中国医药
- 生物化学 生物化学
背景情况:
- 巨细胞两极分化对炎症至关重要,Sirtuin5 (SIRT5) 影响抗炎过程.
- 传统疗法莫克西布施 (moxibustion) 通过糖酸盐/α-甲酸 (α-KG) 的比率调节巨细胞极化.
- 由SIRT5调节的谷氨酸脱酶1 (GLUD1),是α-KG生产的关键.
研究的目的:
- 研究moxibustion对SIRT5-GLUD1-α-KG介导的巨细胞两极分化在炎症条件的影响.
- 为了探索moxibustion的抗炎作用的潜在分子机制.
主要方法:
- 在完整的弗洛恩德辅助剂 (CFA) 诱导关节炎模型中使用了C57BL/6J和Sirt5淘汰赛小鼠.
- 通过ELISA,流细胞计和免疫光检测进行了莫克西布施和MC3482 (SIRT5抑制剂) 的治疗;通过ELISA,流细胞计和免疫光检测评估了炎症,酸盐/α-KG水平和巨细胞群 (M1/M2).
- 采用LC-MS/MS蛋白质组学和西部涂抹/IP来识别和量化SIRT5,GLUD1和化GLUD1.
主要成果:
- 在CFA模型中,moxibustion和MC3482通过减少M1和增加M2巨细胞来减少炎症.
- 治疗逆转了酸盐和α-KG水平,导致酸盐低,α-KG高,以及GLUD1酸化增加.
- LC-MS/MS将GLUD1确定为SIRT5脱结合的蛋白质,由西方涂抹和IP证实.
结论:
- 催化剂的抗炎作用与通过SIRT5-GLUD1通路调节巨细胞极化有关.
- 通过GLUD1的翻译后修改,SIRT5抑制和莫克西布斯提升M2巨细胞的两极分化,通过改变糖酸盐/α-KG平衡.

Inflammatory Response
1.8K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
