reported the novel category of monoclonal IgG deposition disease characterized by membranoproliferative glomerulonephritis or endocapillary glomerulonephritis on light microscopic findings, staining for a single light-chain isotype and a single gamma heavy-chain subclass on immunofluorescence findings, and granular electron-dense deposits on electron microscopic findings [1].
In the glomerulus of Model group, there were subepithelial as well as intramembranous deposition of electron-dense deposits, whereas in the BSA group electron-dense deposits were present in subepithelial region only.
