Increased ETA receptor signaling in the kidney is associated with progression of IgAN1
Explore the Pathogenesis of IgAN
Watch this video to discover the mechanism of disease of IgAN, a heterogeneous glomerular disease.
IgAN is Characterized by a Multi-hit Disease Model1
In Hit 4, overactivation of the endothelin and complement systems contributes to the progression of IgAN1
In Hit 4, overactivation of the endothelin and complement systems contributes to the progression of IgAN1
These processes may lead to proteinuria, inflammation, and fibrosis, which can cause progressive kidney damage1
Explore the burden of patients living with IgAN
Learn how IgAN impacts their day-to-day lives
