一、Toll样受体的分类 Toll样受体(Toll-like receptors, TLRs)是一类非常重要的蛋白质,它们在我们的免疫系统中扮演着关键角色。它们属于模式识别受体(pattern recognition receptors, PRRs),是我们天然免疫反应中的第一道防线,可以识别病原体相关分子模式(pathogen-associated molecular patterns, PAMPs)及损伤相关分子模式...
Toll样受体(Toll-like receptors, TLR)是参与非特异性免疫(天然免疫)的一类 重要蛋白质分子,也是连接非特异性免疫和特异性免疫的桥梁。TLR是单个的跨膜非催化 性蛋白质,可以识别来源于微生物的具有保守结构的分子。当微生物突破机体的物理屏障, 如皮肤、粘膜等时,TLR可以识别它们并激活机体产生免疫细胞应答。 相关知...
Toll样受体(Toll like receptors,TLR)是一类进化保守的跨膜先天免疫受体,它们参与保护人体健康的第一线防御,对于识别病原体相关分子模式(PAMP)起重要作用(Kawai,T.等人,Nature Immunol.,11,2010,373‑384)。 TLR表达于各种免疫细胞,根据其表达部位的不同可分为两类:表达于细胞膜的TLR(TLR1/2/4/5/6)和表达...
Mutations in toll-like receptor genes have been associated with an array of diseases. Targeting toll-like receptors with drugs may prove to be therapeutically beneficial. Keywords: toll-like receptors; pattern recognition receptors; inflammation; cytokines; innate immunity...
Fig. 1. Signalling pathways of Toll-like receptors (TLRs). TLRs are present on the cell surface and in endosomes, where they bind different ligands. Upon ligand stimulation, adaptor proteins are recruited to the TIR domain of TLRs and initiate intracellular signalling. Four types of adaptor prot...
TLRs的细胞外/细胞腔结构域,识别亮氨酸富集重复序列,这些化合物识别感染来源配体,并利用其细胞浆保守区域(被认为是toll样/白细胞介素-1受体(TIR)同源结构域区域)传递信号,激活下游信号接头蛋白,包括髓系分化初级反应基因MyD88。 DC细胞虽然在肿瘤微环境中丰度很低,但在协调抗肿瘤反应中发挥重要作用。TLR相关DC的成熟...
Toll-like receptors (TLRs) are a family of pattern recognition receptors that recognize conserved structures that are associated with infection or tissue damage. Activation of TLRs promotes inflammatory responses. Latest Research and Reviews Deficiency ofTlr7andIrf7in mice increases the severity of COVID...
Toll-like Receptors Function TLR signaling can induce a variety of functions in cells, which are dependent on the specific receptor, cell type, and other co-stimulatory signals involved. TLRs can stimulate expression of pro-inflammatory cytokines, proliferation and survival mechanisms, and facilitate ...
Toll-like receptor (tōl′līk′) n. Any of a class of proteins that are located within membranes, often on the cell surface, and are an important part of the innate immune system. Toll-like receptors recognize and bind to pathogens or to fragments resulting from cell damage and then activ...
