Dr. Wilson is a Professor of Cellular and Molecular Medicine, a member of the Bio5 Institute and is affiliated with the Cancer Biology and Neuroscience Graduate Interdisciplinary Programs. The research in Dr. Wilson's laboratory focuses on membrane trafficking in polarized cells, with an emphasis on how functional membrane domains are generated and maintained. As a graduate student, she performed transmission electron microscopic studies of transepithelial transport across the yolk sac. These studies led naturally to post-doctoral studies of endosomal structure in the intestine. This interest has continued, and she has investigated various aspects of endocytosis, recycling, and degradation of membrane proteins in epithelial cells and neurons.
Using morphological, biochemical, and molecular biological approaches, Dr. Wilson has led studies into the mechanisms of biogenesis and targeting of endosomal proteins, polarized targeting of apical proteins, and trafficking of tight junction proteins. The role of membrane trafficking in the establishment and maintenance of epithelial polarity is an area that she finds particularly fascinating. Loss of polarity is a hallmark of cancer, and current paradigms suggest that loss of polarity may be an early event in the transformation process.
Dr. Wilson's laboratory has extensive experience with the culture, manipulation, transfection, and imaging of mammalian cells. They use these approaches to define how membrane trafficking regulates morphogenesis, signaling, and fate in normal cells and how changes in these pathways could lead to cancer.
