Renal glomerulus biology and diseases

Glomerular diseases are the most common cause of end-stage renal disease. We investigate the molecular profile of healthy and diseased glomeruli with the aim to discover molecular pathways that drive the progression of glomerular disorders. We use transgenic mouse and zebrafish models to understand the role of identified pathways in the biology and diseases of the kidney.
