Toll样受体是近几年发现的天然免疫受体 ,它们不仅能特异性地识别病原微生物的结构成分 ,激活天然免疫 ,同时也为激活获得性免疫提供共刺激信号。Toll样受体是天然免疫与获得性免疫之间的连接点 Toll-like receptors are innate immune receptors found in recent years. They not only recognize the structural components of pathogenic microorganisms specifically, activate innate immunity, but also provide costimulatory signals for activating adaptive immunity. Toll-like receptors are the junction between innate and acquired immunity
