Cationic lipids and polymers for gene delivery
Gene therapy, aiming to eradicate causes rather than symptoms of diseases, is believed to be the therapy of the future. A new promising area for the application of gene therapy is the emerging field of regenerative medicine, where gene delivery can be used to enhance or modify cell functions in an organ/tissue or in engineered substitutes. The aim of gene therapy is to achieve the expression of...
متن کاملLipitoids--novel cationic lipids for cellular delivery of plasmid DNA in vitro.
BACKGROUND Although synthetic nonviral vectors hold promise for the delivery of plasmid DNA, their gene-transfer efficiencies are far from matching those of viruses. To systematically investigate the structure-activity relationship of cationic lipids, a small library of cationic lipid-peptoid conjugates (lipitoids) was synthesized. The compounds were evaluated for their ability to form complexe...
متن کاملNovel Cholesterol-Based Cationic Lipids as Transfecting Agents of DNA for Efficient Gene Delivery
The design, synthesis and biological evaluation of the cationic lipid gene delivery vectors based on cholesterol and natural amino acids lysine or histidine are described. Cationic liposomes composed of the newly synthesized cationic lipids 1a or 1b and neutral lipid DOPE (1,2-dioleoyl-L-α-glycero-3-phosphatidyl-ethanolamine) exhibited good transfection efficiency. pEGFP-N1 plasmid DNA was tran...
متن کاملNeutron reflectometry to investigate the delivery of lipids and DNA to interfaces (Review).
The application of scattering methods in the study of biological and biomedical problems is a field of research that is currently experiencing fast growth. In particular, neutron reflectometry (NR) is a technique that is becoming progressively more widespread, as indicated by the current commissioning of several new reflectometers worldwide. NR is valuable for the characterization of biomolecul...
متن کاملEfficient Delivery of Plasmid DNA Using Cholesterol-Based Cationic Lipids Containing Polyamines and Ether Linkages
Cationic liposomes are broadly used as non-viral vectors to deliver genetic materials that can be used to treat various diseases including cancer. To circumvent problems associated with cationic liposome-mediated delivery systems such as low transfection efficiency and serum-induced inhibition, cholesterol-based cationic lipids have been synthesized that resist the effects of serum. The introdu...
