Research Abstract:

My research focuses on two rare but important genetic kidney diseases, Alport syndrome and Pierson syndrome. Each is a disease of the glomerular basement membrane (GBM), a major component of the kidney’s glomerular filtration barrier. Basement membranes are specialized extracellular matrices that play critical roles in embryonic development, organ function, and disease. Of particular interest are members of the laminin and collagen IV families and their roles in the GBM. We have generated Col4 and laminin knockout mice that model distinct human genetic kidney diseases (Alport and Pierson syndromes, respectively) and used them to show that laminin and collagen IV are critical for maturation and function of the GBM. One interest of the lab is to define exactly what structure—cell or matrix—serves as the kidney’s filtration barrier. We are using our mouse models of human kidney disease to test potential therapies with both NIH and industry funding.

We have recently been using CRISPR/Cas9 technology in vivo to introduce mutations found in human Pierson into the mouse to investigate mechanisms of pathogenesis. These experiments led us to discover novel genetic interactions between the laminin and collagen IV networks in the GBM and to a serendipitous in frame laminin mutation that causes a chronic nephrotic syndrome. We are using these mouse models to test innovative therapies aimed at restoring the structure and function of the GBM as proofs-of-principle to slow kidney disease progression in patients.

We are employing super-resolution fluorescence microscopy (STORM) to analyze mouse and human kidney sections in normal and various disease states. We are characterizing changes in the position of extracellular matrix proteins in the GBM and alterations in shape and cytoskeleton of the adjacent specialized epithelial cells, which are called podocytes. This has led to a new understanding of how the glomerular filtration barrier becomes defective in the setting of injury.
