MAPK信号转导通路对炎证反应的调控

丝裂原活化蛋白激酶（ｍｉｔｏｈｅｎ－ａｃｔｅｖａｔｃｄ ｐｒｏｔｅｉｎ ｋｉｎａｓａ,ＭＡＰＫ）是生物体内重要的信号转导系统之一,参与介导生长、发育、化裂、分化、死亡以及细胞间的功能同步等多种细胞过程,在哺乳动物细胞中已发现和克隆了ＥＲＫ、ＪＮＫ／ＳＡＰＫ、ｐ３８／ＲＫ、ＥＲＫ５／ＢＭＫ１四个ＭＡＰＫ亚族。这些ＭＡＰＫ能被多种炎性刺激所激活,并对炎症的发生、发展起生重要调控作用。研究感染和炎症反应

Regulation of inflammatory responses by MAPK signal transduction pathways

Mitogen activated protein kinase (MAPK), which is one of the important signal transduction systems in organisms, is involved in many cellular processes, such as cell growth, development, division, differentiation, death and coordination of cellular functions, and etc. Four subfamilies of MAP kinases, i e ERK, JNK/SAPK, p38/RK and ERK5/BMK1, have been identified and cloned in mammalian cells These MAP kinases are activated by many proinflammatory stimuli and play an important role in the pathogenesis and development of inflammation. In this article recent advances in the study of the mechanisms underlying activation of MAPKs in infection and inflammation and the molecular basis of specific inhibitors for MAPKs are reviewed, in special reference with the perspective prevention and treatment of inflammation by these kinases.
