Ganoderma Lucidum Polysaccharides: The Ultimate Immune Modulator for Health and Longevity

1. What Are Ganoderma Lucidum Polysaccharides?

Ganoderma lucidum polysaccharides (GLPs) are bioactive β-D-glucans extracted from the fruiting bodies, mycelia, or spores of 霊芝 (Reishi mushroom). Structurally, they comprise β-(1→3)-D-glucan backbones と β-(1→6)-D-glucosyl branches, forming triple-helix configurations critical for immunomodulatory activity. With molecular weights ranging from 10–1,000 kDa, these heteropolysaccharides contain glucose, galactose, mannose, and xylose residues. Their unique helical conformation enables potent binding to immune cell receptors (e.g., dectin-1, TLR-4), triggering cytokine cascades and macrophage activation369.

2. 原料、化学特性、技術仕様

Botanical Sources & Extraction

• Primary Source: Fruiting bodies of 霊芝 または G. sinense (highest GLP content: 1.8–2.5% dry weight)39.

• Extraction Methods:

  • Hot water extraction (95°C, 3h) → ethanol precipitation → deproteinization (Sevag reagent)

  • Ultrasonic-assisted extraction (40 kHz) → macroporous resin (AB-8) purification → lyophilization

3. Health Benefits, Optimal Dosage & Safety

Validated Therapeutic Effects

• Immunomodulation:

  • ↑ Macrophage phagocytosis by 300% and ↑ NK cell cytotoxicity by 150% via TLR4/NF-κB pathway activation39.

• 抗腫瘍活性:

  • Induces apoptosis in HepG2 cells (IC₅₀: 50 μg/mL) through caspase-3 activation and Bcl-2 suppression69.

• Metabolic Regulation:

  • ↓ Fasting blood glucose by 32% in diabetic models via AMPK/GLUT4 signaling9.

• Hepatoprotection:

  • Reduces ALT/AST levels by 65% in ethanol-induced liver injury models3.

Dosage Recommendations

• 一般的な健康: 100–300 mg/day (20–30% GLPs)

• Therapeutic Use:

  • Immune support: 500 mg/day (≥40% GLPs)

  • Adjuvant cancer therapy: 1,000–1,500 mg/day

• Safety Threshold: ≤3,000 mg/day (no observed toxicity)9.

重要な注意事項

• Autoimmune Conditions: May overstimulate Th1 responses (avoid in lupus/RA).

• Surgery: Discontinue 2 weeks pre-operation (potential immunostimulatory effects).

• 薬物相互作用: May potentiate immunosuppressants (e.g., cyclosporine).
