Methods and materials for identifying and treating membranous nephropathy based on elevated Semaphorin 3B

Abstract

This document relates to methods and materials involved in identifying and/or treating mammals having membranous nephropathy (e.g., membranous nephropathy with an elevated level of a Semaphorin 3B polypeptide in the glomerular basement membrane (GBM)). For example, methods and materials for administering one or more immunosuppressive agents (e.g., corticosteroids, cyclosporine, or a B-cell reduction or depletion agent such as Rituximab) to treat a mammal (e.g., a human) having membranous nephropathy are provided.
