Abstract

Glucocorticoids (GC) are universally accepted agents for the treatment of anti-inflammatory and immunosuppressive disorders. They are used in the treatment of rheumatic diseases and various inflammatory diseases such as allergy, asthma and sepsis. They bind with GC receptor (GR) and form GC-GR complex with the receptor and exert their actions. On activation the GC-GR complex up-regulates the expression of nucleus anti-inflammatory proteins called as transactivation and down-regulates the expression of cytoplasmic pro-inflammatory proteins called as transrepression. It has been observed that transactivation mechanisms are notorious for side effects and transrepressive mechanisms are identified for beneficial anti-inflammatory effects of GC therapy. GC hampers the function of numerous inflammatory mediators such as cytokines, chemokines, adhesion molecules, arachidonic acid metabolites, release of platelet-activating factor (PAF), inflammatory peptides and enzyme modulation involved in the process of inflammation. The GC resistance is a serious therapeutic problem and limits the therapeutic response of GC in chronic inflammatory patients. It has been observed that the GC resistance can be attributed to cellular microenvironment changes, as a consequence of chronic inflammation. Various other factors responsible for resistance have been identified, including alterations in both GR-dependent and GR-independent signaling pathways of cytokine action, hypoxia, oxidative stress, allergen exposure and serum-derived factors. The present review enumerates various aspects of inflammation such as use of GC for treatment of inflammation and its mechanism of action. Molecular mechanisms of anti-inflammatory action of GC and GC resistance, alternative anti-inflammatory treatments and new strategy for reversing the GC resistance have also been discussed.

摘要

糖皮质激素(GC)是治疗抗炎和免疫抑制性疾病的普遍公认药物。它们用于治疗风湿性疾病和各种炎症性疾病,如过敏、哮喘和败血症。它们与糖皮质激素受体(GR)结合,与受体形成GC-GR复合物并发挥作用。激活后,GC-GR复合物上调称为反式激活的核抗炎蛋白的表达,并下调称为反式抑制的细胞质促炎蛋白的表达。据观察,反式激活机制因副作用而声名狼藉,而反式抑制机制则被认为是GC治疗有益抗炎作用的原因。GC会阻碍多种炎症介质的功能,如细胞因子、趋化因子、黏附分子、花生四烯酸代谢产物、血小板活化因子(PAF)的释放、炎症肽以及炎症过程中涉及的酶调节。GC抵抗是一个严重的治疗问题,限制了GC在慢性炎症患者中的治疗反应。据观察,GC抵抗可归因于慢性炎症导致的细胞微环境变化。已确定了导致抵抗的各种其他因素,包括细胞因子作用的GR依赖性和GR非依赖性信号通路的改变、缺氧、氧化应激、过敏原暴露和血清衍生因子。本综述列举了炎症的各个方面,如GC用于治疗炎症及其作用机制。还讨论了GC抗炎作用和GC抵抗的分子机制、替代抗炎治疗以及逆转GC抵抗的新策略。
