KATHARINA HOPP, PH.D.

University of Colorado Denver

Biography

Dr. Katharina Hopp, Ph.D., is as Assistant Professor at the University of Colorado, Denver, Anschutz Medical Campus, where her lab studies the pathomechanisms that drive kidney cyst growth using a wide variety of rodent models and in vitro cell culture systems. Specifically, her lab researches the functional role of immune cells in PKD progression. She is interested in understanding the interplay between immune cells and the cystic epithelium and whether it could be therapeutically targeted to slow kidney cyst growth. More recently, Dr. Hopp became inspired by findings from the cancer field highlighting that metabolic dysregulation impacts the anti-tumor function of immune cells. Appreciating the effect that metabolic reprogramming has on PKD pathology, her lab studies how dysregulated metabolism alters the cystic immune microenvironment and whether dietary/metabolism-based approaches can prime immune cells in functioning to slow cyst growth. Lastly, Dr. Hopp directs a preclinical PKD core which utilizes a variety of murine PKD models, in vivo imaging techniques, toxicology and pharmacodynamic assays, and detailed pathology analyses to evaluate therapeutic efficacy of novel compounds aimed to slow PKD progression.

MAX CHRISTOPH LIEBAU, M.D.

University Hospital Cologne

GREGORY PAZOUR, PH.D.

University of Massachusetts

Biography

Dr. Pazour is currently a Professor of Molecular Medicine at the University of Massachusetts Medical School.  He obtained his PhD from the University of Minnesota studying the plant pathogen Agrobacterium.  This was followed by post-doctoral studies at the Worcester Foundation for Biomedical Research where he made the unexpected connection between cilia in the green alga Chlamydomonas and cystic kidney disease.  His laboratory focuses on understanding the mechanisms of ciliary assembly and the role that cilia play in mammalian health and development.  In particular the Pazour group is interested in the function of the intraflagellar transport proteins.  This thirty-protein complex is critical to build cilia and is evolutionarily conserved across eukaryotes from green algae to humans.  Defects in most intraflagellar transport proteins block ciliary assembly and cause cystic kidney disease, retinal degeneration and structural birth defects in many organs including the kidney.  Current work is focused on the intersection between ciliary assembly processes and sensory functions of cilia.

DR. OWEN WOODWARD, PH.D.

University of Maryland School of Medicine

Biography

Dr. Woodward is an Associate Professor in the Departments of Physiology and Medicine, at the University of Maryland School of Medicine. Dr. Woodward earned his undergraduate degree from the University of Virginia and received his PhD at the University of Washington, Seattle. He completed his postdoctoral training at the Johns Hopkins University School of Medicine with Dr. Bill Guggino, and joined the Physiology faculty at the University of Maryland in 2013.

The driving interest of the Woodward laboratory is to understand how ion channels and transporters operate and are regulated to produce the specific physiological functions of the kidney. This includes how these functions are altered in genetic diseases like Polycystic Kidney Disease, where the Woodward Laboratory has focused on building the next generation of renal epithelial 2D and 3D model systems to study the initial mechanisms of cystogenesis following the loss of PKD1 and PKD2 function. Current work relates to how the polycystins regulate renal epithelial cell and tubule morphology.

ALAN YU, M.B., B.CHIR

University of Kansas Medical Center

Biography

Dr. Yu directs a laboratory-based research program that investigates renal tubule physiology and diseases. A current focus is on understanding paracellular epithelial transport and its regulation. Paracellular transport occurs through tight junctions and is mediated by a family of channels called claudins. The investigation of claudins promises to reveal novel fundamental insights into the pathogenesis of many diseases, including acute kidney injury, salt-sensitive hypertension and kidney stone disease. Dr. Yu also performs clinical research in polycystic kidney disease. He is particularly interested in translating bench research findings about cell signaling pathways into drugs and therapeutics, especially repurposed drugs, and testing them in early phase human trials.

Dr. Yu is a general nephrologist who sees the full spectrum of kidney diseases. He has a special interest in fluid, electrolyte and acid-base disorders, including hyponatremia, hypernatremia, hypokalemia, hyperkalemia, hypomagnesemia, renal tubular acidosis, and inherited tubulopathies, particularly Barrter’s and Gitelman’s syndrome.
