GI Hepatology Research

In the UAB Division of Gastroenterology/Hepatology, we are actively engaged in both basic science and clinical research. We maintain comprehensive research facilities and programs that allow us to participate in the development of new understandings and therapies associated with gastrointestinal disorders. Our diverse research programs and centers which include the UAB Liver Center and the UAB Muscosal HIV & Immunobiology Center (MHIC) foster collaborative research projects not only at UAB but throughout the world. We also utilize the Gastroenterology/Hepatology Clinical Research Program (GHCRP), which provides a specialized infrastructure to facilitate clinical research for faculty members.

Current basic science research

  • Regulation of mucosal immune response to antigens in the intestine.

  • Elucidation of pathophysiologic mechanisms underlying chronic intestinal inflammation.

  • Analysis of T cell repertoire in autoimmune human liver disease and viral hepatitis.

  • Animal model to study autoimmune liver disease/cholangiopathies.

  • Mucosal immune responses, particularly the responses of mucosal macrophages to gastrointestinal pathogens, including HIV-1, cytomegalovirus, and H. pylori.

  • Pathogenesis of the biochemical and clinical manifestations in the porphyrias.

  • Gene mutation in bovine protoporphyria.

  • Molecular basis of vascular complications of chronic liver disease with special interest in hepatopulmonary syndrome

Current clinical research

  • Viral Hepatitis C

  • New therapies for ulcerative colitis and Crohn’s disease.

  • Mechanisms of host resistance to intestinal infections.

  • Development and application of prolonged ambulatory pH and pressure monitoring in esophageal diseases.

  • Evaluation of the mechanisms and treatments of a variety of gastrointestinal complications associated with HIV infection.

  • Diagnosis and management of acute and chronic pancreatitis.
