Summary
Liposomes show promise as protein carriers for drug delivery and vaccines, but challenges remain in creating stable formulations. Solvent-free methods are preferred for manufacturing liposomal protein delivery systems.
Area of Science:
- Pharmaceutical Science
- Biotechnology
- Drug Delivery Systems
Background:
- Liposomes are explored as carriers for proteins in pharmaceutical applications.
- Potential uses include sustained release, enhanced absorption, and targeted delivery.
- Current applications are primarily in preclinical stages with limited human data.
Purpose of the Study:
- To review liposomal protein formulations and their applications.
- To discuss challenges in developing stable and bioactive protein-lipid formulations.
- To compare solvent-free and solvent-based preparation methods.
Main Methods:
- Review of recently reported methods for liposomal protein formulation.
- Comparison of advantages and disadvantages of different preparation procedures.
- Consideration of large-scale manufacturing and protein recovery.
Main Results:
- Liposomes offer potential for protein delivery, vaccine adjuvancy, and hydrophobic compound administration.
- Significant challenges persist in achieving commercial stability and bioactivity.
- Solvent-free vesicle preparation is highlighted as a preferred approach.
Conclusions:
- Developing stable liposomal protein formulations requires careful manufacturing design.
- Solvent-free methods are recommended for preparing protein-based liposomes.
- Further research is needed to overcome manufacturing and stability challenges for clinical translation.
