Reversible cell-specific drug delivery with aptamer-functionalized liposomes.

cis-Diamminedichloroplatinum(II) (cisplatin) is a potent chemotherapeutic agent for the treatment of a broad range of cancerous tumors. Despite its excellent antitumor efficacy, the major drawbacks of cisplatin include its lack of tumor specificity and severe side effects. In addition, certain tumor-cell types develop resistance to cisplatin from exposure to the drug. Strategies that allow the ...

Drug Delivery via Cell Membrane Fusion Using Lipopeptide Modified Liposomes

Efficient delivery of drugs to living cells is still a major challenge. Currently, most methods rely on the endocytotic pathway resulting in low delivery efficiency due to limited endosomal escape and/or degradation in lysosomes. Here, we report a new method for direct drug delivery into the cytosol of live cells in vitro and invivo utilizing targeted membrane fusion between liposomes and live ...

Cationic Liposomes Modified with Polyallylamine as a Gene Carrier: Preparation, Characterization and Transfection Efficiency Evaluation.

Purpose: Cationic polymers and cationic liposomes have shown to be effective non-viral gene delivery vectors. In this study, we tried to improve the transfection efficiency by employing the advantages of both. Methods: For this purpose, modified polyallylamines (PAAs) were synthesized. These modifications were done through the reaction of PAA (15 KDa) with acrylate and 6-bromoalkanoic acid deri...

Ferritin-conjugated plant agglutinins as specific saccharide stains for electron microscopy: application to saccharides bound to cell membranes.

An electron microscopic stain for specific saccharides was prepared by the conjugation of ferritin to concanavalin A, a plant agglutinin that specifically binds to oligosaccharides containing terminal d-glucose, d-mannose, or sterically related sugar residues. A technique was developed to allow topological visualization of erythrocyte and other membranes by means of transmission electron micros...

The Distribution and Asymmetry of Mammalian Cell Surface Saccharides Utilizing Ferritin-conjugated Plant Agglutinins as Specific Saccharide Stains

The preparation, properties, and some applications of ferritin conjugates of two plant agglutinins, concanavalin A and Ricinus communis agglutinin, are reported. These conjugates serve as specific electron-dense stains for cell- and membrane-bound saccharide residues of the alpha-D-mannopyranosyl and beta-D-galactopyranosyl configurations, respectively, and as examples of a wide range of ferrit...
