Iga nephritis etiology As the patient's skin and liver can be detected iga deposition, suggesting that systemic disease. Because in the glomerular mesangial area and capillaries can have granular iga and c3 deposition, suggesting that the immune complex pathogenesis. The current study revolves around the ability of the antigen to pass through the mucosa, whether the mucosal barrier is defective, whether the iga structure is defective, and whether the immunomodulatory function is defective. Early studies have suggested that iga deposited in this disease may be mucosal. However, recent studies have used highly specialized techniques to confirm that the disease is iga1, mainly systemic, mainly produced by the bone marrow and lymphatic system; mucosal iga2 is mainly found in the liver Glial sclerosis in iga deposition. In the patients cycle can also be seen in the total iga1 and iga1-containing immune complex increased bone marrow iga1 produced by the increase in plasma cells and t...
