Plant-Based Biomaterials as Bio-Instructive Immunomodulators: Design Principles, Mechanisms, and Translational...

Area of Science:

• Biomaterials Science
• Immunology
• Regenerative Medicine

Background:

• Plant-based biomaterials, derived from terrestrial plants and marine macroalgae, are recognized for their bio-instructive properties.
• These materials are rich in polysaccharides and secondary metabolites crucial for immune engineering.

Purpose of the Study:

• To review plant-derived polysaccharides and phytochemicals as immunomodulators in biomedical applications.
• To explore mechanisms of immune modulation and applications in tissue regeneration.

Main Methods:

• Literature review synthesizing evidence on plant-derived compounds and their immune effects.
• Analysis of mechanisms including macrophage polarization, receptor engagement, and redox regulation.
• Discussion of material design, delivery systems, and applications in wound and musculoskeletal regeneration.

Main Results:

• Plant-derived polysaccharides (algal and terrestrial) and phytochemicals exhibit significant immunomodulatory roles.
• Key mechanisms involve macrophage polarization, pattern recognition receptor signaling, and metabolic regulation.
• Material properties and advanced delivery systems influence immune responses and therapeutic outcomes.

Conclusions:

• Plant-based biomaterials offer promising avenues for immune engineering and regenerative medicine.
• Standardized characterization and immune validation are crucial for translational success.
• Addressing variability and regulatory challenges is essential for clinical application.
