胱天蛋白酶募集域蛋白 9(caspase recruitment domain-containg protein 9，CARD9)属于 CARD 家族中的一员，存在于脾、肝、胎盘、肺、脑等人体多种组织中，是高度表达于中性粒细胞、巨噬细胞及树突细胞等髓系细胞中的一个重要衔接蛋白。CARD9可与Bcl-10、黏膜相关淋巴组织淋巴瘤转运蛋白1(mucosa-associated lymphoid tissue lymphoma translocation protein 1，MALT-1)结合并形成CARD9-Bcl-10-MALT-1(CBM)复合体，作为C型凝集素受体(C-type lectin receptor，CLR)等通路的重要媒介，激活核因子κB(nuclear factor κB，NF-κB)等炎症信号通路，在抗真菌免疫中发挥重要作用。迄今为止，全世界已报道14个国家共56例患者发生18种CARD9突变的报道，真菌类型涉及念珠菌、皮肤癣菌、暗色真菌及曲霉等。本文针对CARD9突变在不同真菌感染性疾病中的研究进展进行综述。

Caspase recruitment domain-containing protein 9 (CARD9), one of the CARD family members, is an essential adapter in myeloid cells, and is expressed in various tissues, including the spleen, liver, placenta, lung and brain. By forming a complex with Bcl-10 and mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1), CARD9 mediates C-type lectin receptors (CLRs)-triggered intracellular signaling and nuclear factor κB (NF-κB) activation, which is therefore crucial in antifungal immunity. Evidence indicates that CARD9 mutations lead to increased susceptibility to various fungal infections. To date, 18 missense and nonsense CARD9 mutations have been reported in 56 patients from 14 countries, which is linked with a variety of fungal infections including Candida, Dermatophytes, Dematiaceous fungi, Aspergillus, etc. This review aims to summarize recent progress in CARD9 mutation and different fungal infections.
