Research Summary:
Dr. Muzykantov works in the field of drug targeting. His research interests are focused in the areas of vascular targeting of enzyme therapeutics for containment of oxidative and thrombotic vascular stress, inflammation, endothelial injury and ischemia-reperfusion. The more new, powerful therapeutic agents are designed, the higher is interest in two questions: i) how to minimize their side effects via a more adequate delivery to therapeutic targets - an affected organ, tissue or cell; and, ii) how to improve their effects by precise addressing into the desirable subcellular compartments. For example, many enzymes and other therapeutic proteins are available in purified or recombinant forms and could find therapeutic use, but their sub-optimal delivery to therapeutic targets restricts therapeutic effects and cause side effects.

Muzykantov explores two strategies for delivery of anti-thrombotic enzymes: carriage by red Blood cells and immunotargeting to endothelial surface determinants using recombinant fusion protein constructs. He also designs strategies for intracellular immunotargeting of drugs into endothelial cells using vehicles including immunoconjugates and polymer nanocarriers directed to cell adhesion molecules. This research includes studies of: i) Role of carriers geometry (size and shape) and endothelial environment, flow and functional status in targeting and endothelial responses to targeting; ii) The mechanisms of sub-cellular and trans-cellular addressing of targeted cargoes; and, iii) Pharmacokinetics, therapeutic and potential side effects in animals. Methodology includes protein biochemistry, bioconjugation and bioengineering; design of polymer carriers for drug delivery, morphological and imaging techniques, nano-technologies, recombinant, cell and molecular biology techniques; animal studies. The goal of this research, supported by grants from NIH and the Penn Research Foundation, is better understanding of action and optimization of design of drug delivery strategies and translation into the clinical domain.
