Emerging Approaches in Glioblastoma Treatment: Modulating the Extracellular Matrix Through Nanotechnology

Area of Science:

• Oncology
• Biotechnology
• Materials Science

Background:

• Glioblastoma (GB) presents a complex tumor microenvironment (TME) characterized by a dense extracellular matrix (ECM).
• The TME and ECM contribute significantly to GB progression, therapeutic resistance, and invasive behavior.
• Current GB treatments face challenges including the blood-brain barrier and ECM penetration.

Purpose of the Study:

• To provide a comprehensive review of glioblastoma (GB), its TME, and current treatment limitations.
• To explore the potential of nanotechnology in overcoming GB treatment challenges.
• To highlight nanotechnology-based strategies for modulating the GB ECM to improve therapeutic efficacy.

Main Methods:

• Review of existing literature on glioblastoma, its TME, and nanotechnology applications.
• Focus on nanoparticle formulations (liposomes, polymeric nanoparticles, gold nanoparticles) for targeted delivery.
• Analysis of strategies to modulate the extracellular matrix (ECM) density in glioblastoma.

Main Results:

• Nanotechnology demonstrates promise in targeting the GB TME and ECM.
• Nanoparticle formulations can enhance drug delivery across the blood-brain barrier and through the dense ECM.
• Targeted delivery improves treatment efficacy and diagnostic accuracy within the tumor site.

Conclusions:

• Nanotechnology presents an innovative approach to advance glioblastoma (GB) treatment by addressing TME and ECM barriers.
• Nanoparticle-based strategies offer a promising avenue for improving drug distribution and therapeutic outcomes in GB.
• Further research into nanotechnology and GB ECM modulation is crucial for enhancing patient survival rates.
