促肾上腺皮质激素释放因子在炎症性肠病中的研究进展

近年来,越来越多的证据表明应激可干扰神经系统,进而通过脑-肠轴的交互作用引起免疫紊乱,在炎症性肠病(IBD)的发病中起重要作用。促肾上腺皮质激素释放因子(CRF)是一种与应激反应密切相关的神经内分泌肽,其家族成员通过与受体结合,调节机体在应激状态下的下丘脑-垂体-肾上腺(HPA)轴功能,在协调应激相关内分泌、自主神经、免疫、行为等反应中起重要作用。在慢性肠道炎症中,脑和肠黏膜中的CRF系统成员被激活以调节肠道局部和中枢免疫反应。本文对CRF在IBD中作用的研究进展作一综述。

Advances in Study on Corticotropin-releasing Factor in Inflammatory Bowel Disease

It has become increasingly evident that stress is implicated in the development of inflammatory bowel disease （IBD） via initial nervous disturbance and subsequent immune dysfunction through brain-gut interaction. Being a principal neuroendocrine coordinator of stress responses, corticotropin-releasing factor （CRF） and its related peptides regulate the hypothalamic-pituitary-adrenal （HPA） axis and coordinate the endocrine, autonomic, immune and behavioral responses to stress through its receptors. In chronic intestinal inflammation, the members of CRF system in brain and colonic mucosa are activated, regulating both the local and central immune response. This article reviewed the advances in study on the role of CRF in IBD.
