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. This evidence concerns the gene CD74 and glomerulonephritis.
