Research Focus

Our group is interested in inflammatory and malignant gastrointestinal disorders, in particular acute pancreatitis and pancreatic ductal adenocarcinoma. In both disorders inflammatory and neoplastic insults lead to a pronounced activation of the pancreas microenvironment resulting in highly complex transcriptional and biophysical alterations through the activation of a variety of cells such as pancreatic stellate cells, stem cells, inflammatory/immune cells, and a dynamic stromal response. More recently, a pancreas-specific tumor microbiome has been described that may have profound, yet unkowm implications on benign and malignant diseases of the pancreas. The Neesse laboratory aims to investigate this exciting and emerging field in a combined translational and clinical research program. To this end, a broad spectrum of (epi-) genetic, biochemical, transcriptional and 3rd generation sequencing approaches are employed to dissect the distinct roles of the various cell types and their mutual interaction within the pancreas microenvironment during acute pancreatic inflammation and neoplastic transformation. Ultimately, we aim to rapidly translate our findings to novel diagnostic and therapeutic concepts for patients.

Our group has initiated several prospective clinical-translational and one retrospective clinical trials.
