Abstract

This review describes the challenges and therapeutic applications of nanodelivery systems for treatment of airway diseases. Therapeutic applications of nanodelivery in airway diseases involve targeted delivery of DNA, short interfering RNA, drugs, or peptides to hematopoietic progenitor cells and pulmonary epithelium to control chronic pathophysiology of obstructive and conformational disorders. The major challenges to nanodelivery involve physiologic barriers such as mucus and alveolar fluid. It is necessary for the nanoparticles to be biodegradable and capable of providing sustained drug delivery to the selected cell type. Once inside the cell, the nanoparticle should be capable of escaping the endocytic degradation machinery. In addition, for effective gene delivery, nuclear entry and chromosomal integration are critical. The strategies to overcome these pathophysiologic barriers are discussed as an attempt to synchronize the efforts of pulmonary biologists, chemists, and clinicians to develop novel nanodelivery therapeutics for airway diseases. From the Clinical Editor: Therapeutic applications of nano-delivery in airway diseases involve targeted delivery of DNA, siRNA, drugs or peptides to hematopoietic progenitor cells and pulmonary epithelium. These nano-particles must be biodegradable, capable of providing sustained drug delivery to specific cells, and should escape the endocytic degradation machinery. For effective gene-delivery they should also provide nuclear entry and chromosomal integration.
