| 摘 要： | 固有免疫系统利用模式识别受体识别病原相关分子模式。近期研究发现,外源DNA能够被宿主细胞中多种DNA受体识别,激活多种信号通路,上调Ⅰ型干扰素和促炎性细胞因子的表达。基于DNA的免疫识别在激活宿主抗感染免疫过程中起重要作用,因此仅对现已报道的DNA受体进行概述,同时对DNA的免疫识别与自身免疫病之间的关系进行探讨。

| Abstract: | The innate immune system deploys pattern recognition receptor(PRR) to detect pathogen-associated molecular pattern(PAMP). Microbial DNA could be recognized by various host DNA sensors that are either membrane-bound or located in the cytosol, and stimulate the production of type I interferons and proinflammatory cytokines. DNA-stimulated innate immune activation plays an important role in antimicrobial response as well as certain autoimmune diseases. The recent progress in identification of novel DNA sensors in host cells, and the related signaling pathways that lead to the innate immune activation were summarized. |
