Abstract
in English, Chinese

Toll like receptors (TLRs) are expressed mainly on innate immunocytes such as dendritic cells and macrophages, and may have the potential to recognize and bind to pathogen-associated molecular patterns (PAMPs) from Candida albicans, thereby triggering the downstream signals. The genetic polymorphism of TLRs is associated with susceptibility to Candida albicans. The activation of TLRs by PAMPs from Candida albicans can induce the production of proinflammatory cytokines that play key roles in the anti-infection of Candida albicans. However, in order to evade the immune response of host,Candida albicans can also change its bacterial phase. Understanding of the interaction between TLRs and Candida albicans will provide novel evidence to further clarify the mechanisms of anti-fungal immune response.

Toll样受体（TLR）是一类主要表达于树突状细胞和巨噬细胞等固有免疫细胞上的模式识别受体，能识别和结合白假丝酵母菌上的病原相关分子模式，并引起特定下游信号转导。TLR多态性与宿主对白假丝酵母菌的易感性有关，TLR激活后可诱导促炎性细胞因子的表达，发挥抗白假丝酵母菌感染作用；而白假丝酵母菌也可发生菌相改变以利于逃逸机体免疫反应。了解TLR和白假丝酵母菌之间的相互作用，可为阐明抗真菌感染免疫的机制提供新的实验依据。
