摘要: 国内外研究表明TLR4在银屑病和过敏性紫癜患者中的体内表达上调。TLRs信号过度活化时,激活机体内炎症反应,导致炎性细胞大量浸润及细胞因子过度释放,可使体内Th1/Th2免疫应答失衡,干扰机体自身免疫耐受机制,导致免疫功能紊乱。本文对银屑病和过敏性紫癜的与TLR4介导的免疫研究进展进行了综述。

Abstract: Domestic and foreign researches showed that the expression level of TLR4 was up-regulated in the patients with psoriasis and henoeh-schonlein purpura. Over activated signals of TLRs can lead to inflammatory response in the body, cause infiltration of large number of inflammatory cells and over release of cell factors, which may interfere with the self immune tolerance mechanism of body and lead to immune function disorder, including the imbalance of Th1/Th2 immune response. The immune response induced by TLR4 in the development of psoriasis and henoeh-schonlein purpura was reviewed.

Key words: TLR4, psoriasi, henoeh-schonlein purpura
