Targeted modulation of immune cells and tissues using engineered biomaterials

Area of Science:

• Immunology and Materials Science
• Biomedical Engineering
• Drug Delivery Systems

Background:

• Immunomodulatory therapies hold promise for treating diverse conditions like cancer, infectious diseases, and autoimmunity.
• Current immunotherapies face challenges in specificity, dosage control, and targeted delivery.
• Biomaterials offer a platform to overcome these limitations by controlling immune cell interactions.

Purpose of the Study:

• To review recent advancements in biomaterials-based strategies for immunotherapy.
• To highlight how biomaterials can target specific immune cell subsets.
• To discuss the potential of biomaterials in improving vaccine and immunotherapy efficacy and safety.

Main Methods:

• Review of literature on biomaterials for immune system modulation.
• Focus on strategies targeting lymphoid tissues, circulating leukocytes, and tissue-resident immune cells.
• Analysis of biomaterial applications in various disease contexts.

Main Results:

• Biomaterials enable precise targeting of immune cells in lymphoid tissues and at disease sites.
• These materials can modulate the dosage, timing, and location of immune stimulation.
• Biomaterial strategies show potential for enhancing both immunity and tolerance.

Conclusions:

• Biomaterials represent a powerful tool for advancing immunotherapies and vaccines.
• Targeted delivery and controlled modulation by biomaterials improve treatment outcomes.
• Future research in biomaterials will likely drive significant progress in treating immune-related diseases.
