Neuron-Targeted Nanoparticle for siRNA Delivery to Traumatic Brain Injuries.
Traumatic brain injuries (TBIs) affect 2.5 million Americans per year, and survivors of TBI can develop long-term impairments in physical, cognitive, and psychosocial functions. Currently, there are no treatments available to stop the long-term effects of TBI. Although the primary injury can only be prevented, there is an opportunity for intervention during the secondary injury, which persists ...
متن کاملsiRNA delivery and targeting.
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...
متن کاملTargeted Delivery of siRNA
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...
متن کاملAptamer mediated siRNA delivery
Nucleic acids that bind to cells and are subsequently internalized could prove to be novel delivery reagents. An anti-prostate specific membrane antigen aptamer that has previously been shown to bind to prostate tumor cells was coupled to siRNAs via a modular streptavidin bridge. The resulting conjugates could be simply added onto cells without any further preparation, and were taken up within ...
متن کاملsiRNA conjugate delivery systems.
Small interfering RNA (siRNA) has been chemically conjugated to a variety of bioactive molecules, lipids, polymers, peptides, and inorganic nanostructured materials to enhance their pharmacokinetic behavior, cellular uptake, target specificity, and safety. To efficiently deliver siRNAs to the target cells and tissues, many different siRNA bioconjugates were synthesized and characterized, and th...
