Mucosal targeting in IgA nephropathy targeting the gut associated lymphoid tissue.

Abstract

IgA nephropathy is a mucosally driven disease and new therapeutic approaches are specifically targeting the mucosal production of IgA in the hope that this will lead to a reduction in circulating IgA immune complexes and mesangial IgA deposition. In this lecture, I discuss the rationale for targeting the mucosal immune system of the gut and the existing data from clinical trials supporting such an approach as a disease modifying treatment for IgA nephropathy.
