Abstract: Effective delivery of drugs is a major problem in today’s therapeutics. At a fundamental level, the challenge of drug delivery reflects the fact that the drug distribution in the body is limited by body’s natural metabolic processes and transport barriers. These biological barriers, while serving an important purpose of regulating body’s metabolic functions, limit the drug dose that ultimately reaches the target site. Accordingly, many drugs fail to reach their full therapeutic potential. Our research aims to understand body’s key biological barriers and develop novel means to negotiate these barriers to deliver drugs. We have developed means to use body’s own circulatory cells including red blood cells, macrophages, monocytes, neutrophils, NK cells and T cells to overcome body’s barriers and deliver drugs to target tissues for the treatment of cancer, autoimmune disorders and trauma. I will present an overview of these strategies and their efficacy in drug delivery.
