Liposomes against Alzheimer's Disease: Current Research and Future Prospects

Area of Science:

• Neuroscience
• Pharmacology
• Biotechnology

Background:

• Alzheimer's disease (AD) is a prevalent neurodegenerative disorder affecting over 60 million globally, characterized by cognitive and behavioral decline.
• Current treatments face challenges due to the blood-brain barrier (BBB) limiting drug delivery to the brain.
• Effective drug delivery systems are crucial for managing AD progression.

Purpose of the Study:

• To review the application of liposomes as a drug delivery system for Alzheimer's disease.
• To focus on the role of liposome functionalization in enhancing brain targeting and therapeutic outcomes.
• To discuss the challenges associated with delivering therapeutics across the BBB.

Main Methods:

• Literature review summarizing research on liposomes for AD treatment.
• Analysis of liposome functionalization strategies (e.g., lactoferrin, PEG, transferrin) for improved BBB penetration.
• Discussion of existing challenges in brain drug delivery.

Main Results:

• Liposomes, due to their lipid bilayer structure, can mimic the BBB and facilitate drug transport.
• Functionalized liposomes demonstrate improved targeting specificity and delivery efficiency compared to non-functionalized counterparts.
• Various functional moieties enhance liposome interaction with the BBB and brain tissue.

Conclusions:

• Liposomes represent a promising strategy for overcoming BBB limitations in Alzheimer's disease treatment.
• Functionalization of liposomes is key to enhancing their brain-targeting capabilities.
• Further research into advanced liposomal drug delivery systems is warranted to improve AD management.
