Light microscopy, immunohistochemical examinations and electron microscopy of kidney biopsies showed the different localization of immune complexes in the glomeruli (subepithelial, intramembraneous, subendothelial, and mesangial immune complexes) and various forms of materialization of their harmful effect (induction of immune inflammation or immunosuppression) to be determined by the involvement in phagocytosis and reparation reactions of either podocytes or mesangial and endothelial cells and also hematogenous elements. Therefore, podocyte, mesangioendothelial and podocyte-mesangioendothelial ways of morphogenesis of immunocoplex glomerulonephritis may be distinguished. Each of them is associated with the development of certain clinico-morphological forms of immunocomplex glomerulonephritis which should be considered as distinct entities.
