    本研究我们主要围绕着“分析IgA肾病(IgAN)患者外周血和肾脏组织中调节性T细胞(Treg)/Th17/Th1/Th2细胞的数量和其对B细胞分泌IgA的影响,结合临床表现、病理类型、治疗反应、临床结局进行分层分析”进行研究。其中在“IgA肾病遗传易感基因及其相关致病机理”研究方面,我中心在该研究领域有突破性的重大进展。通过全基因组关联分析研究,首次发现了中国人群中IgA肾病独有的两个新的易感基因位点,证明了遗传因素在IgA肾病的发病机制中起重要作用,并能够影响IgA肾病的发病过程及临床表现。研究结果对科学家们更深入地了解IgA肾病发生的分子机制,探索IgA肾病风险预测标记,并为未来IgA肾病的早期诊断、个体化治疗和新的干预靶点及新药研发提供了坚实的基础。 通过本研究,我们对Treg/Th17细胞及其它非T细胞依赖途径对B细胞分泌IgA1的影响在IgAN发病中的作用及MMF治疗IgAN的疗效及耐受性方面有了初步的认识。本研究旨在应用最新免疫学基础研究理论,利用我国丰富的临床病例资源与合作方先进的基础研究成果和技术方法,分析T细胞不同亚群在IgA肾病发病机制中的作用及可能机制,并且开展前瞻随机对照临床研究探讨MMF治疗IgA肾病疗效和耐受性。为临床防治IgA肾病提供目标和依据。 In this project,we focus on‘Analyzing the quantity of regulatory T cells(Treg)/Th17/Th1/Th2 in Peripheral blood and kidney tissue of patients with IgA nephropathy(IgAN),and its effect on B cells secreting IgA,integrating clinical manifestation,pathological type,response to treatment,clinical outcomes for stratified analysis’.Among studies of‘IgAN susceptibility genes and related pathogenesis’,we had a major breakthrough in this field.Using genome wide association study(GWAS),for the first time we found two new susceptibility loci in Chinese IgAN,demonstrating genetic factor plays an important role in the pathogenesis of IgAN,and affecting disease process and clinical manifestation.The paper was published in the international journal of Nature Genetics.The study results offer solid foundation for helping scientists better understand the molecular pathogenesis of IgAN,exploring disease risk predicted markers,also achieving early diagnosis,individual treatment,finding new targeting points and drugs for the disease in the future. The effects of Treg/Th17 cells and other T cell independent way in B cells secreting IgA1 were indicated in our study.We also comprehended the efficacy and tolerance of MMF in the treatment of IgAN.The aim of study is to exploring the role of T cell subsets in the pathogenesis of IgAN,using updated immune theory,our abundant clinical resources and advanced technologies,outstanding achievements of our partner.On this beneficial platform,we also carried out a prospective randomized control study“The efficacy and tolerance of low dose of prednisone combined with MMF in the treatment of IgAN”to probe new evidence of IgAN treatments.
