Macromolecular (Immuno-)Therapeutics

Macromolecular (Immuno-)Therapeutics

Macromolecular delivery systems can improve pharmacokinetic behavior of powerful drugs and broaden their application. Besides improving therapies agains pathologic phenomena in living cells and tissues directly, our primary research interests also focus on modulating the body’s own immune system in order to recognize and eliminate pathogens or malignancies and provide long-lasting immunity against them.

Nano-sized macromolecular delivery systems can provide key features to address components of the immune system and delivery immune modulating compounds. For that purpose, we design well-defined block copolymers with self-assembling and responsive properties. The resulting nano-sized carriers can sense various stimuli including temperature, pH or light and provide reactivity to amino acid residues as well as specific receptor binding properties. Key feature of them is their biodegradability towards nanoparticle disassembly under physiologically relevant conditions over time.

Together with our partners from the Collaborative Research Center SFB 1066 we utilize these carriers for developing selective immune-responses in vitro and in vivo. In addition, strategies to stimulate immune activity and especially to modulate regulatory properties of the tumor microenvironment are investigated in order to combat cancer via next generation nano-immunotherapeutics.
