摘要
目的通过系统性红斑狼疮(SLE)患者外周血单个核细胞(PBMCs)的磷蛋白组学分析,为SLE的进一步机制研究及治疗奠定基础。方法收集15例SLE患者和15例健康受试者的外周血,使用TiO2富集PBMCs的磷酸化肽段,进行质谱分析,然后进行磷酸化肽段和磷酸化位点鉴定,并进行生物信息学分析。结果 SLE患者与正常人存在有差异的1 035个磷酸化位点,与标注蛋白对应的基因有618个。共筛选出12条代谢通路,其中丝裂原活化蛋白激酶(MAPKs)通路含差异的磷酸化位点最多。结论 SLE患者PBMCs具有差异的磷酸化蛋白质及肽段,与代谢通路一起可作为SLE发病机制研究参考和补充,并可作为治疗靶点研究。
