Immunomodulation: Acai Polysaccharides & Macrophage Activation
By Phytochemical & Botanical Research Council•
Clinical Takeaway & Phytochemical Summary
Innate immunity: high-molecular-weight arabinogalactan polysaccharides, natural killer (NK) cell cytotoxicity, and balanced Th1/Th2 cytokine modulation.
Beyond small-molecule anthocyanins, acai pulp contains complex arabinogalactan polysaccharides that exert potent stimulatory effects on innate immune surveillance.
1. Immune Cell Kinetics
- Macrophage Phagocytosis: Acai polysaccharides bind toll-like receptors (TLR4), priming alveolar and peritoneal macrophage responsiveness.
- Natural Killer (NK) Cell Activity: Enhanced granzyme B and perforin secretion improves baseline defense against intracellular pathogens.
- Th1/Th2 Homeostasis: Moderate interferon-gamma induction fosters cellular immunity without exacerbating allergic Th2 hyperreactivity.
