摘要: 目的 用高通量蛋白质芯片技术筛选多发性硬化(Multiple Sclerosis,MS)患者血清中可能存在的自身抗体,为筛选新的疾病辅助性诊断的指标奠定基础。方法 15例MS患者作为疾病组,选取同样数量MS阴性并无其他自身免疫疾病的性别和年龄相匹配的健康人15位作为健康对照组。两组组内随机分为三个小组,血清充分混匀后,采用高通量蛋白质芯片法检测MS患者血清中可能存在的自身抗体。结果 通过高通量蛋白质芯片技术检测及与对照组分析比对,共筛出MS患者血清27种自身抗体。其中阳性率较高为SLC16A4、NOL3和DTX1,提示其可能是MS患者血清中特异性自身抗体的靶蛋白。阳性蛋白数量上,MS组高于HC组。功能聚类结果显示,自身抗体主要针对神经相关的蛋白质。结论 采用高通量蛋白质芯片技术,可以较为有效筛选出MS血清中的自身抗体的靶抗原,为进一步验证MS相关自身抗体的功能及作用机制奠定了基础。

Abstract: Objective To identify some new autoantibodies, as the assistant serum diagnostic indicator for multiple sclerosis (MS)Methods The experimental samples were consisted of two groups: MS patients group and health control(HC) group, each group contains 15 samples. For proteome array detection, both groups were separated into 3 smaller groups randomly and the sera of each smaller group would be mixed sufficiently before using. Results After comparing with HC group,have identified 27 kinds of autoantibodies, among which the NOL3, SLC16A4 and DTX1targeted autoantibodies have a higher positive rate. The total of autoantibodiesdetected from MS group are much more than HC group. The functional cluster analysis indicated that the autoantibodies are mainly targeting the neuron associated proteins.Conclusions The study indicated that the high-throughput proteome array is highly suitable for the discovering of autoantibodies in serum. The result has certain guidance over our further research.
