1. Cholestatic pruritus. Patients with various forms of cholestasis often suffer from chronic itch (pruritus). This can be a very heavy burden to the patient. The mechanism of cholestatic itch is unknown. Bile salts and endogenous opioids have been implicated but we have found no evidence to support this contetnion. We have set up assays to analyze the effect of cholestatic factors on neuronal signalling. Currently, we are analyzing the factors that we have identified and we are trying to elucidate the mechanism by which they cause itch. This will provide means to implement existing drugs or develop new drugs against this agonizing problem (collaboration with prof. Ulrich Beuers).
2. The (patho)physiological function of soluble adenylyl cyclase (sAC). Soluble adenyl cyclase is an enzyme that synthesizes the potent signaling molecule cyclic AMP. sAC is the evolutionary oldest adenylyl cyclase but it has hardly been studied so far. We are investigating its role in regulation of apoptosis, the Warburg effect (in relation to cancer and immune cell metabolism), and barrier function of epithelial cells.It appears that sAC has a regulatory role in various important cell-autonomous functions
2. Hepatic transport functions. Many aspects of bile formation have been elucidated in the past decades. However, several aspects of normal bile formation and especially of biliary dyfunction and cholestasis are not well understood. We are improving animal models for cholestatic diseases; not only with respect to defects in transport function but also with respect to the role of bile salt signalling and the role of biliary bicarbonate secretion. In addition, we are trying to unravel the factors that contribute to the development of autoimmunitiy against bile duct epithelial cells as occurs in primary biliary cirrhosis (collaboration with prof. Ulrich Beuers)
