表型提示
MGI:109186Mice homozygous for a null allele are viable but show impaired NADPH oxidase responses of neutrophils to a variety of stimuli and defective killing of S. aureus in vitro and in vivo. Homozygotes for a knock-in allele that prevents PtdIns3P binding to thePX domain fail in development prior to E10.
Ncf4(Neutrophil cytosolic factor 4),也被称为p40phox,是NADPH氧化酶复合物的一个组成部分。NADPH氧化酶是一种酶复合物,负责在吞噬细胞中产生超氧阴离子,这是一种活性氧(ROS),对于吞噬细胞杀死病原体至关重要。Ncf4的缺陷会导致慢性肉芽肿病(CGD)的一种温和且非典型的形式,这种病的特点是吞噬细胞缺乏NADPH氧化酶活性,从而无法产生足够的超氧阴离子来对抗病原体。

Ncf4基因的缺陷与多种疾病相关。在慢性肉芽肿病中,Ncf4/p40phox的缺陷是一种较轻的类型,患者通常不会出现侵袭性细菌或真菌感染。这种类型的CGD可以通过血清-包被的E.coli作为刺激物在二氢罗丹明(DHR)测定中诊断[1]。此外,Ncf4基因的多态性还与慢性心力衰竭在2型糖尿病患者中的风险增加有关[2]。Ncf4基因的变异还与炎症性肠病(IBD)的易感性有关,Ncf4基因的缺陷导致中性粒细胞功能障碍,从而无法控制肠道微生物组,并导致适应性免疫系统的激活,进而引起组织损伤[3]。在类风湿性关节炎(RA)中,Ncf4基因的变异与RA的易感性相关[4]。此外,Ncf4还与动脉粥样硬化的诊断相关,MMP9、ALOX5、NCF2、NCF1和NCF4被认为是动脉粥样硬化的诊断基因,并且与氧化应激有关[5]。Ncf4还可以通过调节抗原呈递来限制自身反应性和关节炎性T细胞的激活,从而防止自身免疫性关节炎的发生[6]。Ncf4的表达还与儿童败血症相关,MAPK14、ITGAM、HK3、ALOX5、CR1、HCK、NCF4、PYGL、FLOT1、CARD6、NLRC4、SH3GLB1、PGS1、RAB31和LTB4R被认为是儿童败血症的诊断标记物[7]。Ncf4基因的变异还与结直肠癌的风险增加有关[8]。在牛乳腺炎中,NCF4基因的变异也与乳腺炎的易感性有关[9]。

综上所述,Ncf4是一种重要的基因,其缺陷与多种疾病相关,包括慢性肉芽肿病、慢性心力衰竭、炎症性肠病、类风湿性关节炎、动脉粥样硬化、败血症、结直肠癌和乳腺炎。Ncf4的研究有助于深入理解NADPH氧化酶复合物的生物学功能和疾病发生机制,为疾病的治疗和预防提供新的思路和策略。
