髓样细胞触发受体-1研究进展

摘要

髓样细胞触发受体-1是新近发现的免疫球蛋白超家族成员之一.其主要通过与其配体结合被激活后发生交联反应,或者通过增加转录因子的水平,从而激发、放大炎症反应,促进抗炎因子下调.髓样细胞触发受体-1可以看作是诊断感染性疾病的标志物,它的阻断可能成为治疗炎症性疾病的一种新方法.该文对其结构、信号传导、表达、调节以及在临床上的应用进行阐述.%Triggering receptor expressed on myeloid cells-1 ( TREM-1 ) is one of immunoglobulin superfamilies found recently.TREM-1 is a crucial molecule for the triggering and amplification of inflammatory response and promote the reduction of in anti-inflammatory factor by crosslinking reaction with its ligand after being activated,or increasing the level of transcription factor.This study shows that TREM-1 may be claimed as a marker of infection,and the blockade of TREM-1 may be a new approach to inflammatory diseases.This study summarizes its structure,signal transduction,expression,accommodation and clinical application.
