Tissue Regeneration and Inflammation Imaging
The aim of this group is the development and validation of molecular imaging techniques for the investigation of inflammatory, fibrotic and carcinogenic processes. Our research consists of four main lines. First, we focus on the development of targeted compounds for the detection of early biomarkers of carcinogenesis, cancer progression or tissue regeneration by multimodal (PET, SPECT, MRI and optical) imaging. Secondly, selected compounds are tested for their suitability as targeted or adjuvant cancer theranostics. Examples of such compounds are selective cyclooxygenase-2 inhibitors for both functional characterization and therapeutic modulation of inflammatory processes. Selective transglutaminase 2 inhibitors in turn address matrix-modifying processes. Third, we develop and study three-dimensional (3D) cell models and animal models for solid, in particular therapy-resistant tumors with a distinct inflammatory and/or fibrotic matrix-associated microenvironment to improve our understanding of the disease process. Examples are pancreatic ductal adenocarcinoma (PDAC) and hepatocellular carcinoma (HCC). Fourthly, intelligent biomaterial approaches for targeted drug delivery, combined therapies and targeted modulation of tissue regeneration are of central importance to us in this context.
