Dr. Heather Francis
The goal of my laboratory is to investigate synergistic role that cholangiocytes and mast cells during cholestatic liver injury, specifically Primary Sclerosing Cholangitis (PSC), cholangiocarcinoma and non-alcoholic fatty liver disease (NAFLD). My lab is currently funded by both the NIH and the VA and these studies examine the link between cholangiocytes, mast cells and hepatic stellate cells during liver disease focusing primarily on PSC. In addition, we recently found that using OTC drugs that block histamine receptors (H1HR and H2HR inhibitors) decreases both PSC and cholangiocarcinoma. Further, we are particularly interested in the HDC/histamine/histamine receptor axis and the autocrine (from cholangiocytes) and paracrine (mast cells) role this axis plays in PSC, cholangiocarcinoma and NAFLD. Using genetic knockout mice, we have demonstrated that loss of HDC and/or loss of mast cell activation ameliorates liver damage including biliary hyperplasia and hepatic fibrosis that are send during PSC. Our recent studies have demonstrated that there is a synergistic relationship between cholangiocytes and mast cells and damaged, senescent cholangiocytes may be the cause for mast cell infiltration during liver damage. Our studies are clinically relevant since mast cells are found surrounding bile ducts and are activated during liver damage. In addition, we have shown that histamine levels are increased in patients with PSC, cholangiocarcinoma, NAFLD, NASH and end-stage liver disease. We are aiming to fully exploit the role of mast cells during liver disease progression using a number of approaches including genetic models and pharmaceutical targeting. Our goal includes defining molecular targets that might be translated into therapeutic options for patients suffering from liver disease.
