Project description:The goal of the project was to identify risk alleles that are associated with recurrence of membranous nephropathy in the graft after kidney transplantation. First, we sequenced PLA2R1 and HLA-D loci in 248 patients with primary membranous nephropathy and identified two independent single nucleotide polymorphisms (SNPs) at risk for primary membranous nephropathy at each locus. Then we investigated whether primary membranous nephropathy at-risk variants were associated with recurrence in a retrospective cohort of 105 donor-recipient pairs and a replication cohort of 40 pairs.

Project description:Our understanding of the pathogenesis of idiopathic membranous nephropathy is limited by an incomplete molecular characterization of the cell types in the kidney and interaction between the cells. Besides, the reason for the heterogeneity of these patients as well as the variety of clinical outcomes remains elusive. Therefore, we applied scRNA-seq to kidney biopsies of patients with IMN to identify gene expression at the single-cell level, elucidate cells involved in the progression of IMN, and uncover intercellular interactions.

Project description:Background: Multiple autoantigens have been identified in membranous nephropathy (MN) by tissue-based proteomics. However, the antigenic targets of disease are unknown for >10% of MN and >50% of membranous lupus nephritis (MLN) cases. We identified multiple new targets in PLA2R-/THSD7A-/EXT-/NELL1-quadruple negative MN biopsies through mass spectrometry (MS) of immune complexes recovered from biopsy tissue of patients with MN. Methods: MN cases negative for PLA2R, THSD7A, EXT1/2, and NELL1 were identified from a biopsy database. Protein G immunoprecipitation was used to recover immune complexes from frozen biopsy tissue, followed by interrogation by mass spectrometry (MS). Potential antigens were confirmed through paraffin immunofluorescence of protein targets, followed by co-localization with IgG within immune deposits. Consecutive series of 165 cases of PLA2R-negative MN biopsies and 95 MLN biopsies was screened to determine the frequency for each potential antigen. Results: Seven protein targets were discovered within immune complexes from MN biopsies including FCN3, CD206, EEA1, SEZ6L2, NPR3, MST1, and VASN. Peptides from these proteins on MS were not enriched in PLA2R (n=86), THSD7A (n=64), NELL1 (n=64), or EXT1/2 (n=60) controls. Between 3-30 unique peptides were detected for each target. Frequencies of each antigen, determined by staining consecutive case series, were SEZ6L2 (1/165 idiopathic; 0/95 MLN), VASN (8/165 idiopathic; 2/95 MLN), EEA1 (6/165 idiopathic; 7/95 MLN), MST1 (6/165 idiopathic; 2/95 MLN), and FCN3 (0/165 idiopathic, 6/95 MLN), NPR3 and CD206 were positive in index cases. All cases showed co-localization of IgG within immune deposits. Conclusion: Seven novel protein targets were identified in MN and MLN.
