Liposomes with cerasome-forming lipids as gene therapy vectors

Abstract

Basic research focuses on liposome transport systems as non-viral ways of transferring genetic and therapeutic substances. Due to electrostatic interactions between positive polar groups of cationic lipids and the negatively charged cell membrane surface, nucleic acids may readily be transported into cells as part of lipoplexes. Cationic liposomes, however, have a number of well-known problems, including low stability, toxicity, and a potential for severe immunological response. Recent research has revealed, however, that by increasing the system with additional components such as cerasome-forming lipids, these problems may be solved. They aid in the prolongation of the release of a beneficial liposome load in cells by increasing vesicle stability in the systemic circulation.This circumstance broadens the applications for liposomal systems. As a consequence, using varied lipids can create numerous liposomes for use in a range of medical fields. Nonviral delivery approaches based on hybrid liposomes with suitable structural component selection may be a possible response to a number of medical concerns, and further study is urgently needed.
