| I. Background | |
Toll 樣受體（TLR）是一種模式識別受體（PRR），高度保守，可識別各種類型的微 生物病原體相關(guān)模式分子（PAMP）。在人類中發(fā)現(xiàn)了 10 個 Toll 樣受體家族（TLR1-10） 成員，在小鼠中發(fā)現(xiàn)了 12 個成員（TLR1-9、TLR11 and TLR13）。TLR1、TLR2、TLR4、 TLR5 和 TLR6 分布在細(xì)胞膜表面；TLR3、TLR7、TLR8、TLR9 和 TLR10 分布在細(xì)胞內(nèi) 涵體膜表面（TLR3 識別 dsRNA，TLR9 識別 dsDNA）。TLRs 下游信號的激活主要依賴于 兩類轉(zhuǎn)錄因子：NF-κB 和干擾調(diào)節(jié)因子（IRFs），它們主要誘導(dǎo)促炎細(xì)胞因子和 I 型干擾 素（IFN）的產(chǎn)生。 | |
