Gene Delivery with Ultrasound and Microbubbles
Gene therapy and treatment with siRNA hold potential to treat a wide variety of different diseases. Genetic material is not usually stable and is generally hydrolyzed following intravascular administration. This makes the delivery of genes somewhat problematic since intact genetic material must usually be delivered intracellularly for therapeutic effect. For gene therapy, in most cases the gene...
متن کاملTheranostic Oxygen Delivery Using Ultrasound and Microbubbles
Means to overcome tumor hypoxia have been the subject of clinical investigations since the 1960's; however these studies have yet to find a treatment which is widely accepted. It has been known for nearly a century that hypoxic cells are more resistant to radiotherapy than aerobic cells, and tumor hypoxia is a major factor leading to the resistance of tumors to radiation treatment as well as se...
متن کاملNoninvasive and Targeted Gene Delivery into the Brain Using Microbubble-Facilitated Focused Ultrasound
Recombinant adeno-associated viral (rAAV) vectors are potentially powerful tools for gene therapy of CNS diseases, but their penetration into brain parenchyma is severely limited by the blood-brain barrier (BBB) and current delivery relies on invasive stereotactic injection. Here we evaluate the local, targeted delivery of rAAV vectors into the brains of mice by noninvasive, reversible, microbu...
متن کاملTargeted, non-viral gene delivery for cancer gene therapy.
The ability to mediate targeted and specific delivery of therapeutics to cancer cells remains one of the most important hurdles in effectively treating cancer. This aspect also remains as one of the greatest limitations of gene therapy as well. Targeted vectors based on the use of DNA-binding agents attached to cell specific ligands or "molecular conjugates" were created with the goal of over-c...
متن کاملLipid microbubbles as a vehicle for targeted drug delivery using focused ultrasound-induced blood-brain barrier opening.
Focused ultrasound in conjunction with lipid microbubbles has fully demonstrated its ability to induce non-invasive, transient, and reversible blood-brain barrier opening. This study was aimed at testing the feasibility of our lipid-coated microbubbles as a vector for targeted drug delivery in the treatment of central nervous system diseases. These microbubbles were labeled with the fluorophore...
