UNDERSTANDING AND OVERCOMING BIOLOGICAL BARRIERS FOR DRUG DELIVERY
Effective delivery of drugs is a major problem in today’s healthcare. At a fundamental level, the challenge of drug delivery reflects the fact that the drug distribution in the body is limited by the body’s natural metabolic processes and transport barriers. These biological barriers, while serving an important purpose of regulating the 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 at developing a fundamental understanding of the body’s key biological barriers such as skin, intestinal epithelium and the immune system, and utilizing this understanding to develop novel means to negotiate these barriers to deliver drugs. Our research has led to the understanding of how transport properties of biological barriers can be modulated to deliver drugs in effective ways for the treatment of diseases such as diabetes and cancer, among others. I will present an overview of the lessons learned from our exploration of these biological barriers.
Samir Mitragotri is the Hiller Professor of Bioengineering and Wyss Professor of Biologically Inspired Engineering at Harvard University. His research has provided new insights into biological barriers of skin and gastrointestinal tract, among others.
