This gene encodes a subunit of interleukin 12, a cytokine that acts on T and natural killer cells, and has a broad array of biological activities. Interleukin 12 is a disulfide-linked heterodimer composed of the 40 kD cytokine receptor like subunit encoded by this gene, and a 35 kD subunit encoded by IL12A. This cytokine is expressed by activated macrophages that serve as an essential inducer of Th1 cells development. This cytokine has been found to be important for sustaining a sufficient number of memory/effector Th1 cells to mediate long-term protection to an intracellular pathogen. Overexpression of this gene was observed in the central nervous system of patients with multiple sclerosis (MS), suggesting a role of this cytokine in the pathogenesis of the disease. The promoter polymorphism of this gene has been reported to be associated with the severity of atopic and non-atopic asthma in children. [provided by RefSeq, Jul 2008]
这个基因编码白细胞介素12，作用于T和自然杀伤细胞的细胞因子的一个亚单位，并且具有生物活性的广泛阵列。白细胞介素12是像由该基因编码亚基的40kD的细胞因子受体所组成的二硫键连接的异二聚体，和一个35 kD的亚基通过IL12A编码。这种细胞因子通过激活巨噬细胞作为Th1细胞发展的一个重要诱导表达。这种细胞因子已被发现是用于维持足够数量的记忆/效应Th1细胞介导长期保护的细胞内病原体重要。在患有多发性硬化（MS）在中枢神经系统中观察到这种基因的过表达，这表明该细胞因子在疾病的发病机理中的作用。该基因的启动子多态性已被报道与小儿过敏性和非过敏性哮喘的严重程度相关联。 [由RefSeq的，2008年7月提供]
