Liposomes and Extracellular Vesicles as Distinct Paths Toward Precision Glioma Treatment

Area of Science:

• Nanomedicine
• Oncology
• Biotechnology

Background:

• Glioblastoma multiforme (GBM) is an aggressive brain tumor with limited treatment options due to its invasive nature and the blood-brain barrier (BBB).
• Nanocarrier systems are being explored to improve drug delivery and targeting for GBM therapy.

Purpose of the Study:

• To compare liposomes and extracellular vesicles (EVs) as nanocarriers for glioblastoma treatment.
• To evaluate their potential in overcoming BBB limitations and enhancing targeted drug delivery.

Main Methods:

• Review and comparative analysis of liposome and EV applications in glioma therapy.
• Evaluation of their mechanisms for traversing the BBB and tumor accumulation.

Main Results:

• Both liposomes and EVs can cross the BBB and target GBM cells.
• Liposomes offer structural flexibility and controlled release, while EVs provide biocompatibility and natural targeting.
• Differences exist in scalability, cargo loading, and translational readiness.

Conclusions:

• Liposomes and EVs present complementary strengths for developing advanced glioma treatment strategies.
• Leveraging these nanocarriers can lead to more effective and targeted therapies for brain tumors.
