人IL 12 RB 1编码IL 12 R β1,一种I型跨膜受体,是IL 12-和IL 23-信号传导复合物的必需组分。IL 12 RB 1被公认为迟发型超敏反应(DTH)的促进者,DTH是限制结核病的免疫反应。然而,最近的数据表明,除了促进DTH,IL 12 RB 1还促进自身免疫。IL 12 RB 1在人类健康中的矛盾作用提出了一个问题,在给定个体中控制IL 12 RB 1功能的因素是什么,以及如何引入IL 12 RB 1功能的个体间变异性?在这里,我们回顾最近的数据表明,在表观遗传,基因组多态性和mRNA剪接水平引入IL 12 RB 1功能的个体差异。这些差异在哪里以及如何导致疾病的易感性和结果也进行了审查。总的来说,最近的数据支持一种模型,其中IL 12 RB 1序列变异性-无论是在基因组水平还是转录后水平引入-都有助于疾病,并且人类IL 12 RB 1并不像我们曾经认为的那样简单。
Human IL12RB1 encodes IL12Rβ1, a type I transmembrane receptor that is an essential component of the IL12- and IL23-signaling complex. IL12RB1 is well-established as being a promoter of delayed type hypersensitivity (DTH), the immunological reaction that limits tuberculosis. However, recent data demonstrate that in addition to promoting DTH, IL12RB1 also promotes autoimmunity. The contradictory roles of IL12RB1 in human health raises the question, what are the factors governing IL12RB1 function in a given individual, and how is inter-individual variability inIL12RB1 function introduced? Here we review recent data that demonstrate individual variability in IL12RB1 function is introduced at the epigenetic, genomic polymorphism, and mRNA splicing levels. Where and how these differences contribute to disease susceptibility and outcome are also reviewed. Collectively, recent data support a model whereinIL12RB1 sequence variability – whether introduced at the genomic or post-transcriptional level - contributes to disease, and that human IL12RB1 is not as simple agene as we once believed.
