Recent advances in non-viral gene delivery

Abstract

Gene therapy has been deemed the medicine of the future due to its potential to treat many types of diseases. However, many obstacles remain before gene delivery is optimized to specific target cells. Over the last several decades, many approaches to gene delivery have been closely examined. By understanding the factors that determine the efficiency of gene uptake and expression as well as those that influence the toxicity of the vector, we are better able to develop new vector systems. This chapter will provide a brief overview of recent advances in gene delivery, specifically on the development of novel non-viral vectors. The following chapters will provide additional details regarding the evolution of non-viral gene delivery systems.
