Nanomedicines Reshape the Tumor Microenvironment: Multidimensional Strategies from Modulating "Barriers" to Metabolic...

Area of Science:

• Oncology
• Nanomedicine
• Cancer Immunology

Background:

• The tumor microenvironment (TME) presents significant barriers to effective cancer therapy.
• Traditional treatments often fail due to the complex and dynamic nature of the TME.
• Nanoparticle-based strategies offer a novel approach to multidimensional TME modulation.

Purpose of the Study:

• To review how engineered nanoparticles remodel the tumor microenvironment (TME).
• To explore nanoparticle strategies for overcoming physical and chemical barriers within the TME.
• To highlight the role of nanoparticles in reprogramming TME metabolism and enhancing anti-tumor immunity.

Main Methods:

• Review of engineered nanoparticles targeting TME components.
• Analysis of nanoparticle-mediated immune cell modulation (NK cells, dendritic cells, T cells).
• Investigation of nanoparticle effects on extracellular matrix and TME metabolic reprogramming (hypoxia, Warburg effect, lipid and adenosine metabolism).

Main Results:

• Nanoparticles precisely target and alter key TME cells and the extracellular matrix.
• Engineered nanoparticles overcome physical and chemical barriers within the tumor.
• Nanoparticles effectively reprogram TME metabolism, alleviating hypoxia and modulating key metabolic pathways.

Conclusions:

• Integrating immune activation with metabolic intervention via nanomedicines offers a potent therapeutic strategy.
• Nanoparticle-driven TME remodeling enhances anti-tumor immunity and restores metabolic balance.
• This synergistic approach holds promise for overcoming treatment resistance and inhibiting tumor progression.
