摘要
Nod2(Card15)及其相关的Nod1(Card4)都属于近年来研究较多的Nod分子家族。Nod蛋白最初被描述为细胞内Caspase和核因子-κB(NF-κB)信号转导通路的活化因子。随着分子生物学和遗传学研究的深入,NOD2(CARD15)基因与克罗恩病(CD)易患体质的关系逐渐明确。与此同时,生物化学研究证实Nod1及Nod2是细菌肽聚糖成分的细胞内识别分子。作者就Nod蛋白介导的细胞内细菌识别与CD的相关性研究作一综述。
Nod2(Cardl5) and its associated Nodl (Card4) belong to the Nod molecular family which has been widely researched in recent years. Nod proteins were initially described as activating factors within the intracellular Caspase and NF-KB signal transduction pathways. With the improvements of Molecular Biology and Genetics, the association of NOD2 ( CARD15 ) gene and the susceptibility of Crohn disease(CD) is becoming more and more legible. While, biochemical studies have revealed that Nodl and Nod2 can recognize different fragments of peptidoglycan respectively. This review focuses on recent insights into the Nods-mediated intracellular bacteria detection and the association of Nod2 and CD.
