Immunoliposome therapy is a targeted drug delivery method that involves the use of liposomes (artificial lipid bilayer vesicles) coupled with monoclonal antibodies to deliver therapeutic agents to specific sites or tissues in the body. [1] The antibody modified liposomes target tissue through cell-specific antibodies with the release of drugs ...
To deliver the molecules to a site of action, the lipid bilayer can fuse with other bilayers such as the cell membrane, thus delivering the liposome contents; this is a complex and non-spontaneous event, however, [23] that does not apply to nutrients and drug delivery. By preparing liposomes in a solution of DNA or drugs (which would normally ...
The most common vehicle currently used for targeted drug delivery is the liposome. [19] Liposomes are non-toxic, non-hemolytic, and non-immunogenic even upon repeated injections; they are biocompatible and biodegradable and can be designed to avoid clearance mechanisms (reticuloendothelial system (RES), renal clearance, chemical or enzymatic ...
Topical drug delivery (TDD) is a route of drug administration that allows the topical formulation to be delivered across the skin upon application, hence producing a localized effect to treat skin disorders like eczema. [1][2] The formulation of topical drugs can be classified into corticosteroids, antibiotics, antiseptics, and anti-fungal. The ...
The enhanced permeability and retention (EPR) effect is a controversial concept [1][2] by which molecules of certain sizes (typically liposomes, nanoparticles, and macromolecular drugs) tend to accumulate in tumor tissue much more than they do in normal tissues. [3][4][5] The general explanation that is given for this phenomenon is that, in ...
Lipid bilayer. This fluid lipid bilayer cross section is made up entirely of phosphatidylcholine. The three main structures phospholipids form in solution; the liposome (a closed bilayer), the micelle and the bilayer. The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules.
Liposomes are spherical shape, phospholipid vesicles that can be formed with one or more lipid bilayers with phospholipids or cholesterols. [45] The ability of liposomes to encapsulate both hydrophobic and hydrophilic drug compounds allowed liposomes to be an efficient drug delivery systems (DDS) to deliver a range of drugs in these nano ...
Liposomes are ("hollow") lipid nanoparticles which have a phospholipid bilayer as coat, because the bulk of the interior of the particle is composed of aqueous substance. In various popular uses, the optional payload is e.g. DNA vaccines , Gene therapy , vitamins , antibiotics , cosmetics and many others.
