Patients with type 1 diabetes typically develop autoantibodies to antigens of the pancreatic islet cells including insulin, glutamic acid decarboxylase and the protein tyrosine phosphatase-related islet antigen 2 protein. Nephrin is a protein shared by the kidney glomeruli, pancreatic beta-cells and islet microendothelia. Since circulating antibodies to nephrin have been shown to cause proteinuria, we wanted to test whether such autoantibodies can be detected in diabetic patients.
