Weimbs, Thomas - University of California, Santa Barbara - Biomolecular Science and Engineering

个人简介

Dr. Weimbs received his doctoral degree from the Department of Biochemistry of the University of Cologne, Germany, in 1993. He conducted postdoctoral research at the Department of Anatomy, University of California at San Francisco until 1999. In the same year, he joined the Department of Cell Biology in the Lerner Research Institute of the Cleveland Clinic as an Assistant Professor where he established his research laboratory focusing on investigating membrane trafficking and epithelial cell polarity as well as molecular mechanisms underlying polycystic kidney disease. In 2005, Dr. Weimbs was recruited to the Department of Molecular, Cellular, and Developmental Biology and moved his laboratory to UCSB. Dr. Weimbs is currently an Associate Professor in MCDB and in the Neuroscience Research Institute.

研究领域

Research in the Weimbs Laboratory is centered around two related areas of investigation: Autosomal-dominant polycystic kidney disease (ADPKD) is considered the most common life-threatening, monogenic inherited disease. ADPKD affects over 600,000 people in the US alone, is a leading cause of kidney failure, and also leads to significant cardiovascular complications. Currently, no treatment exists for this disease, and most patients require renal transplantation or life-long dialysis for survival. Research in the Weimbs Laboratory is aimed at understanding the molecular mechanisms that lead to renal cyst growth and disease progression, and to identify and test new strategies for therapy. SNAREs and epithelial cell polarity: Most human cell types are "polarized", i.e. they exhibit asymmetry, which is essential to their function. This includes epithelial cells that make up most major human organs such as the kidney, liver, lungs, GI tract, exocrine glands etc. Carcinogenesis is accompanied by the progressive loss of epithelial cell polarity. Current research in the Weimbs lab is aimed at investigating novel signaling functions of so-called SNARE proteins which are essential for the establishment and maintenance of cell polarity.
