自身抗体是自身免疫性疾病和癌症的一个标志,但它们也存在于健康个体中。在此,我们对九个数据集进行了荟萃分析,并重点关注健康个体所共有的常见自身抗体。我们基于蛋白质微阵列数据报告了77种常见自身抗体,这些数据是通过对182份健康个体血清针对7653种人类蛋白质以及另外90份健康个体血清针对1666种人类蛋白质进行检测而获得的。不存在性别差异;然而,自身抗体的数量随年龄增长而增加,在青春期左右达到稳定水平。我们使用一个生物信息学流程来确定可能的分子模拟肽,这些肽可能有助于引发这些常见自身抗体。常见自身抗原的蛋白质内在特性如亲水性、碱性、芳香性和柔韧性存在富集现象。亚细胞定位和组织表达分析表明,一些常见自身抗原与循环中的自身抗体是隔离的。 肖姆等人进行了一项荟萃分析,以发现健康个体中存在的常见自身抗体。这些常见自身抗体在青少年时期出现并增加,在青春期达到稳定水平。生物信息学技术表明了分子模拟在其产生过程中的潜在作用以及几种常见的内在生化特性。
Autoantibodies are a hallmark of both autoimmune disease and cancer, but they also occur in healthy individuals. Here, we perform a meta-analysis of nine datasets and focus on the common autoantibodies shared by healthy individuals. We report 77 common autoantibodies based on the protein microarray data obtained from probing 182 healthy individual sera on 7,653 human proteins and an additional 90 healthy individual sera on 1,666 human proteins. There is no gender bias; however, the number of autoantibodies increase with age, plateauing around adolescence. We use a bioinformatics pipeline to determine possible molecular-mimicry peptides that can contribute to the elicitation of these common autoantibodies. There is enrichment of intrinsic properties of proteins like hydrophilicity, basicity, aromaticity, and flexibility for common autoantigens. Subcellular localization and tissue-expression analysis reveal that several common autoantigens are sequestered from the circulating autoantibodies. Shome et al. performed a meta-analysis to discover the common autoantibodies found in healthy individuals. These common autoantibodies appear and increase during youth and plateau at adolescence. Bioinformatics techniques demonstrate the potential role of molecular mimicry in their production as well as several common intrinsic biochemical properties.
