Expression of nephrin in acquired human glomerular disease.

Background: Nephrin is a recently identified protein, which is synthesized in the podocytes and localized in the slit diaphragm area. Nephrin is a cell adhesion molecule of the immunoglobulin superfamily, and presumably is a part of the zipper-like structure of the slit membrane. As the mutation of the gene coding nephrin induces congenital nephrotic syndrome of Finnish type, which is a prototype of nephrotic syndrome, it has been suggested that nephrin also plays a role in acquired proteinuric kidney disease.
