Liposomes as a Novel Drug Delivery System

Abstract

Liposomes and liposome-derived nanovesicles including archaeosomes and virosomes have turn out to be essential service structures in vaccine improvement and the hobby for liposome-primarily primarily based totally absolutely sincerely vaccines has markedly increased. A key gain of liposomes, archaeosomes and virosomes. In general, and liposome-primarily based totally sincerely vaccine transport structures in particular, is their versatility and plasticity. Liposome composition and training may be selected to attain preferred capabilities including choice of lipid, charge, length, length distribution, entrapment and region of antigens or adjuvants. Depending on the chemical properties, water- soluble antigens (proteins, peptides, nucleic acids, carbohydrates, haptens) are entrapped withinside the aqueous inner region of liposomes, at the equal time as lipophilic compounds (lipopeptides, antigens, adjuvants, linker molecules) are intercalated into the lipid bilayer and antigens or adjuvants may be related to the liposome ground each via adsorption or strong chemical linking. Co-formulations containing exclusive sorts of antigens or adjuvants may be blended with the parameters stated to tailor liposomal vaccines for character applications. Special emphasis is given on this overview to cationic adjuvant liposome vaccine formulations.
