Project

Cardiovascular Nanomedicine group at the Section of Experimental Oncology and Nanomedicine (SEON) focuses on the application of nanomedical strategies for the detection and treatment of atherosclerosis. In spite of the recent developments in imaging techniques, many vulnerable plaques still evade the timely detection. Employing ultrasmall superparamagnetic iron oxide nanoparticles (USPIO), which accumulate in macrophages, in order to refine the magnetic resonance imaging should improve the identifiocation and characterization of atherosclerotic plaques and reduce the risk of acute cardiovascular events. We are currently investigating the utility of dextran-coated USPIO for plaque accumulation and characterization in animal model. The conventional pharmacologic therapy of the clinical manifestations of atherosclerosis uses systemic drug administration. This approach has several serious disadvantages, such as considerable side-effects, or low efficacy at tolerated doses. Nanotechnology has the potential to overcome these disadvantages, e.g. by magnetic drug targeting to atherosclerotic plaques. This approach promises a locally-targeted treatment of plaques, which is expected to substantially minimize adverse effects, by lowering the drug cytotoxicity and reducing the required dosage. We are currently investigating the possibility of magnetic particle accumulation under arterial flow conditions ex vivo and the efficacy of magnetic drug targeting in animal model of atherosclerosis. Another key topic of our work is related to biomaterials for cardiovascular applications. In cooperation with Institute of Biomaterials (FAU), we analyse the cell-compatibility of different alginate-based hydrogels for 3D vessel printing and investigate the possibility of improving colonization of polymeric biomatrices using magnetic cell seeding technique. Furthermore, in cooperation with the Department of Functional Materials in Medicine and Dentistry (University Hospital Würzburg), we pursue research aiming at biofabrication of pre-endothelialized microvascular networks based on thermoresponsive polymer technology.

Kevin Bassand, a PhD student from Inserm U1148, Université Paris 13, Laboratory for Vascular Translational Science, Biotherapies and Glycoconjugates Group (Head: Dr. Hanna Hlawaty), is currently visiting SEON. During his 5-week stay, funded by a scholarship from Paris 13 University, he will investigate the role of endothelial glycocalyx on uptake of nanoparticles and the growth of endothelial cells on different polyurethane-based substrates.
