In our data set, four glomerulonephritis samples including two IgAN, one LN and one MN showed higher CD74 mRNA level comparing with donor sample within podocyte, which indicates activation of MIF/CD74 between immune cells and podocyte exists in glomerulonephritis sample, providing a potential marker for glomerulonephritis status. The gene discussed is MIF; the disease is glomerulonephritis.
