摘要
免疫相关GTP酶(IRG)属于γ干扰素诱导性GTP酶家族成员,在γ干扰素介导的宿主抗感染和炎症免疫中起重要作用。正常情况下,IRGM(人类)/Irgm1(小鼠)表达水平较低,在机体受到感染或炎症刺激时,IRGM/Irgm1可被γ干扰素迅速诱导表达并迁移至细胞吞噬溶酶体膜上。目前人们对IRGM/Irgm1在疾病中的研究主要集中在炎性肠病、神经系统疾病以及肿瘤等疾病中。IRGM/Irgm1可能通过介导细胞自噬和凋亡调控疾病的进展,但具体机制目前尚不明确。IRGM/Irgm1作为细胞自噬与凋亡共同的调节蛋白,对多种疾病的发生、发展和转归起重要作用。
The immune related GTPase(IRG)is a member of interferon-γinduced GTPase family,which plays an important role in interferon-γmediated host anti-infection and inflammatory immunity.Under normal conditions,the expression of IRGM(human)/Irgm1(mouse)is low,but when the body is stimulated by infection or inflammation,it can be rapidly induced by interferon-γand transferred to the phagocytic lysosomal membrane.At present,the research of IRGM/Irgm1 in diseases mainly focuses on inflammatory bowel disease,nervous system disease and tumor.It is found that IRGM/Irgm1 may regulate the progress of diseases through mediating cell autophagy and apoptosis,but the specific mechanism is not clear yet.As a common regulatory protein of autophagy and apoptosis,IRGM/Irgm1 plays an important role in the occurrence,development and prognosis of many diseases.
