TLR4(Toll-like receptor 4)是Toll样受体的一个重要的组成成员，是革兰氏阴性细胞壁成份脂多糖(LPS)的识别受体。活化TLR4将诱导产生一系列炎症介质，包括细胞因子、趋化因子等从而产生强有力的炎症反应，TLR4在抗细菌，抗病毒的炎症反应中，以及在应激状态下均发挥重要作用。TLR4在KSHV (Kaposi's sarcoma-associated herpesvirus，卡波西肉瘤相关疱疹病毒)感染的卡波西肉瘤中也有表达，本文就TLR4在KSHV感染的卡波西肉瘤中的信号转导机制及研究进展做一综述。

Toll-like receptor 4 (TLR4) is one of the important members of Toll like receptors, which is a rec-ognition receptor of lipopolysaccharide (LPS), a cell wall component of gram-negative bacteria. Activation of TLR4 induced a series of inflammatory mediators, including cytokines and chemokines, to produce a strong inflammatory re-action. TLR4 played an important role in anti-bacteria, inflammation, antiviral, and stress. TLR4 was also expressed in kaposi's sarcoma, which is infected by Kaposi's sarcoma associated herpesvirus (KSHV). This paper reviewed the most recent advancements of signal transduction mechanism of TLR4 in Kaposi's sarcoma.
