Biorecognition & Drug Delivery
Research in the Kopeček Biomedical Polymers Laboratory focuses on three areas: a) Macromolecular therapeutics with emphasis on development of polymeric drug carriers and novel therapeutic strategies; b) Design of smart biomaterials that self-assemble from hybrid copolymers composed of synthetic polymers and protein/peptide domains; c) Application of biomaterials biorecognition principles to biological systems – drug-free macromolecular therapeutics.
Recent research focuses on the design of backbone degradable, long-circulating polymer carrier – drug conjugates for the treatment of ovarian and prostate cancer and treatment of musculoskeletal diseases, especially osteoporosis. These second-generation conjugates have (when compared to the first generation) longer intravascular half-life and higher accumulation in tumor tissue. Combination therapy targeting both tumor-initiating and differentiated prostate cancer cell populations is also studied.
The research centers on the design of polymer – peptide/protein hybrid biomaterials, whose self-assembly is mediated by coiled-coil and beta-sheet forming peptide domains. These materials are being evaluated as biomineralization matrices for bone tissue engineering and as 3D cell culture scaffolds.
Drug-free macromolecular therapeutics
A new therapeutic approach for the treatment of non-Hodgkin’s lymphoma has been developed.Formation of antiparallel coiled-coil heterodimers or hybridization of complementary oligonucleotides on B-cell surfaces results in crosslinking of CD20 receptors and apoptosis of Raji B cells. This is a new concept, where the biological activity of drug-free macromolecular therapeutics is based on the biorecognition of complementary motifs.
