Barry K Wershil, MD

Professor of Pediatrics (Gastroenterology, Hepatology, and Nutrition)

My laboratory has a longstanding interest in mast cell and eosinophil biology. We have developed specific and novel in vivo approaches for the analysis of mast cell function in experimental gastrointestinal inflammatory and allergic reactions. We can apply this model to determine the precise influence of mast cells and mast cell-derived cytokines/chemokines in gastrointestinal inflammation. My clinical research interest is eosinophilic esophagitis and involves efforts to improve the diagnostic and treatment options for patients

Our research group has extensive experience examining HRQOL and cognitive outcomes in pediatric liver transplant survivors, long term complications related to immunosuppressive medications and the causes and treatment of acute liver failure. Our group has also actively involved in new trials of immunosuppression withdrawal in liver transplant recipients. I am al...

Jeffrey B Brown, MD

I am also interested in understanding the relationship of the intestinal immune system to GI symptoms in rheumatologic disorders, specifically Juvenile Dermatomyositis.As the clinical director of the IBD program, we are involved in the international Improve Care Now network and a participating site in 3 clinical trials.

Anne Rowley, MD

Professor of Pediatrics (Infectious Diseases) and Microbiology-Immunology

A major pediatric research priority and the long-term goal of my laboratory is the identification of the etiology and pathogenesis of Kawasaki Disease (KD), the leading cause of acquired heart disease in children in developed nations. KD can result in coronary artery aneurysm (CAA) formation with resultant myocardial infarction and/or sudden death. Clinical and epidemiologic data are consistent with an infectious cause of KD, but the etiologic agent remains unknown.We hypothesize that a "new" virus enters through the respiratory tract and infects bronchial epithelium, traveling in macrophages ...
