Background:

Nonviral vectors, specifically lipoplexes (plasmid DNA complexed with cationic lipids), are explored as alternatives to viral gene delivery systems.
Lipoplexes avoid the immunological and mutational risks associated with viral vectors.
Current transfection efficiencies of lipoplexes are often insufficient for therapeutic applications.

Purpose of the Study:

To discuss critical steps influencing the transfection efficiency of lipoplexes.
To identify key processes that need thorough investigation for enhancing gene delivery efficacy.

Main Methods:

Review and discussion of the stages involved in lipoplex-mediated gene delivery.
Analysis of lipoplex formation, cell surface interaction, cellular internalization, and nuclear DNA delivery.
