In this article, applications of engineered nanoparticles containing siRNA for inhalation delivery are reviewed and discussed. Diseases with identified protein malfunctions may be mitigated through the use of well-designed siRNA therapeutics. The inhalation route of administration provides local delivery of siRNA therapeutics to the lungs for various pulmonary diseases. A siRNA delivery system ...

In recent years, gene therapy has made tremendous progress in the development of disease treatment. Among them, siRNA offers specificity silencing, ease synthesis, and short period, been intensively studied worldwide. However, as hydrophilic polyanion is easily degraded vivo poorly taken up into cells so, benefits its powerful silencing ability will not be realized until better carriers are dev...

RNA interference (RNAi) is one of the most dramatic findings over the past decade, and the number of publications related to RNAi increased exponentially from 5 in 1998 to more than 2400 in 2008. Generally, RNAi can be achieved by three strategies: chemical synthesized small interfering RNA (siRNA), long double-stranded RNA (dsRNA), and DNA-based (plasmid or viral vector) short hairpin RNA (shR...

Therapeutic application of siRNA requires delivery to the correct intracellular location, to interact with the RNAi machinery within the target cell, within the target tissue responsible for the pathology. Each of these levels of targeting poses a significant barrier. To overcome these barriers several strategies have been developed, such as chemical modifications of siRNA, viral nucleic acid d...
