Abstract
Nucleic acid-based therapeutics present huge potential in the treatment
of pulmonary diseases ranging from lung cancer to asthma and chronic pulmonary
diseases, which are often fatal and widely prevalent. The susceptibility of nucleic
acids to degradation and the complex structure of lungs retard the effective
pulmonary delivery of nucleic acid drug. To overcome these barriers, different
strategies have been exploited to increase the delivery efficiency using chemically
synthesized nucleic acids, vector encapsulation, proper formulation, and
administration route. However, several limitations regarding off-target effects and
immune stimulation of nucleic acid drugs hamper their translation into the clinical
practice. Therefore, their successful clinical application will ultimately rely on
well-developed carriers and methods to ensure safety and efficacy. In this review,
we provide a comprehensive overview of the nucleic acid application for pulmonary
diseases, covering action mechanism of the nucleic acid drugs, the novel delivery
systems, and the current formulation for the administration to lungs. The latest
advances of nucleic acid drugs under clinical evaluation to treat pulmonary
disorders will also be detailed.
