Biomaterials to regulate tumor extracellular matrix in immunotherapy

Area of Science:

• Biomaterials Science
• Cancer Biology
• Immunotherapy

Background:

• The tumor extracellular matrix (ECM) is crucial for tumor growth and metastasis.
• ECM barriers impede drug delivery and immune cell infiltration in tumors.
• Modulating the ECM is vital for enhancing cancer immunotherapy efficacy.

Purpose of the Study:

• To review biomaterial strategies for modulating the tumor ECM.
• To discuss the benefits of ECM modulation for tumor immunotherapy.
• To explore challenges and future directions in this field.

Main Methods:

• Summarizing biomaterial strategies for ECM component modulation (collagen, fibronectin, hyaluronic acid).
• Reviewing ECM remodeling techniques using biomaterials.
• Analyzing the impact of ECM modulation on immunotherapy outcomes.

Main Results:

• Biomaterials effectively modulate ECM composition and structure.
• ECM modulation by biomaterials promotes drug and immune cell infiltration.
• Biomaterials can alleviate the immunosuppressive tumor microenvironment.

Conclusions:

• Biomaterials offer promising strategies for enhancing tumor immunotherapy via ECM modulation.
• Further research is needed to address current challenges and unlock full potential.
• Leveraging biomaterials to engineer the tumor microenvironment is key for improved cancer treatment.
