Retracted: Recent Trends of Polymer Mediated Liposomal Gene Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

The goal of this protocol is to use cationic/anionic liposomes with a neuro-targeting peptide as a CNS delivery system to enable siRNA to cross the BBB. The optimization of a delivery system for treatments, like siRNA, would allow for more treatment options for prion and other neurodegenerative diseases.

The video demonstrates a method for directly transferring the interleukin-15 encoding plasmid DNA into the skin tissue of an interleukin-15 deficient mouse model through acupuncture using microneedles. These microneedles generate micropunctures in the outermost skin layer, facilitating the absorption and transfection of plasmid DNA into the epidermal cells, including keratinocytes, within the skin...

Here we provide a detailed protocol to carry out in vivo cardiac gene editing in mice using recombinant Adeno-Associated Virus(rAAV)-mediated delivery of CRISPR. This protocol offers a promising therapeutic strategy to treat dystrophic cardiomyopathy in Duchenne muscular dystrophy and can be used to generate cardiac-specific knockout in postnatal...

Source: Bender, H. R., et.al. Delivery of Therapeutic siRNA to the CNS Using Cationic and Anionic Liposomes. J. Vis. Exp. (2016)This video demonstrates the targeted delivery of prion protein (PrP) siRNA to neurons using liposomal siRNA-peptide complexes (LSPCs). Cationic liposomes electrostatically bind PrP-targeting siRNA, which is further stabilized by the RVG-9r peptide for receptor-mediated transport across the blood-brain barrier. Once inside the brain, LSPCs undergo endocytosis in...
