The primary focus of Dr. Shirwan's translational research program is to develop safe and practical immunomodulatory approaches with applications to transplantation, autoimmunity, cancer, and infections. To achieve this goal, Dr. Shirwan co-pioneered with Dr. Esma S. Yolcua a proprietary platform technology, ProtEx™, that allows for the generation of novel recombinant immune ligands and their positional display as single agents or in combination on biological surfaces as a practical and safe alternative to gene therapy for localized immunomodulation.
Dr. Shirwan is also assessing various vehicles, including live bacterial vectors and nanoparticles, for targeted delivery of these biologics in vivo to modulate immune effector and regulatory cells for therapeutic outcomes. Ongoing studies demonstrated the efficacy of two lead therapeutic candidates in preventing and treating type 1 diabetes in rodents and are presently being assessed for tolerogenic efficacy in humanized mouse and nonhuman primate models as a prelude to clinical translation. In parallel, candidate immunostimulatory molecules are also being developed for cancer immunoprevention and immunotherapy using rodent and humanized mouse models. A lead candidate in this category was recently shown to train the immune system for long-term protection against various cancer types, the first report of an unusual finding with significant translational potential for cancer as well as infectious diseases.
