树突细胞相关C型凝集素-1受体介导的抗白念珠菌免疫作用及机制

树突细胞相关c型凝集素-1是一种主要的C型凝集素样受体,存在于多种细胞和组织中.它能够特异性识别白念珠菌细胞壁主要成分β-葡聚糖,进而诱导机体产生固有免疫反应和适应性免疫反应.其可单独或与其他模式识别受体相互协同完成上述过程.白念珠菌β-葡聚糖的暴露、树突细胞相关C型凝集素-1表达水平等因素可影响机体免疫效应的强度,对其进行调控将为自念珠菌感染预防和治疗提供一个新的方向.

Abstract：

Dectin-1, a principal C-type lectin pattern-recognition receptor, exists in various types of cells and tissues. It can specifically recognize β-glucans, which are the major cell wall component of Candida albicans, and then trigger the innate and adaptive immune responses in hosts. Dectin-1 can independently, as well as collaboratively with other pattern recognition receptors, induce above mentioned processes. The intensity of immune responses in hosts is modulated by multiple factors such as the exposure of β-glucans on Candida albicans and the expression level of Dectin-1, and this modulation may provide a new direction for the prevention and therapy of Candida albicans infection.
