Mainly caused by a sedentary life style and hypercaloric nutrition, NASH is one of the leading causes of chronic liver disease with the potential of evolving towards end-stage liver disease and hepatocellular carcinoma (HCC), even in the absence of cirrhosis. Every third American and European citizen has a fatty liver. Apart from becoming an increasingly prevalent indication for liver transplantation in cirrhotic and HCC patients, its burden on the healthcare system is also exerted by the increased number of non-cirrhotic NASH patients. Currently, there are no efficient therapies available that would either prevent NASH, revert fibrosis or block NASH to HCC transition.
The Heikenwälder laboratory focuses on comparative studies of human and animal model tissues, recapitulating human disease on a histo-pathological and pathophysiological level, engaging in classical molecular biology techniques complemented with sophisticated ways to receive as much information from tissue samples through histology (e.g. light microscopy/ immune fluorescence/ FISH/ in situ hybridization), other in vivo imaging techniques (e.g. MRI) as well as through FACS analyses for tissue homogenates. At the same time the systemic functional effects of pathologies and the interplay between several affected non-lymphoid organs and the immune system is investigated. Testing several therapeutic compounds in a single but also combinatorial fashion is executed in the Heikenwälder laboratory employing established and stratified pre-clinical mouse models.
In the past the Heikenwälder laboratory has elucidated how the adaptive and innate immune system drives NASH and affects therapy response (e.g. in the context of systemic liver cancer therapy) - which has led to the generation of drugs that are currently tested for clinical use. Mathias Heikenwälder is an elected member of the Leopoldina, most highly cited researcher world-wide from 2018-2022 (“Cross Topic” Web of Science) and has received several prestigious grants (ERC-Stg, ERC-CoG; ERC-POC) and awards (Prof. Max Cloetta award, Götz prize, Walther and Christine Richtzenhain award, Prof. Hans Peter Hofschneider award). In 2022 he has received the German Cancer award.
