Polysaccharides regulate Th1/Th2 balance: A new strategy for tumor immunotherapy

Area of Science:

• Immunology
• Cancer Research
• Pharmacology

Background:

• T helper (Th) cells are vital for anti-tumor immunity.
• Th1 and Th2 cells maintain equilibrium via cytokine secretion, but tumor microenvironments can disrupt this balance.
• Th1/Th2 imbalance is a key factor in malignant tumor development.

Purpose of the Study:

• To comprehensively assess the role of polysaccharides in regulating the Th1/Th2 balance within the tumor microenvironment.
• To systematically summarize the molecular mechanisms by which polysaccharides modulate Th1 and Th2 cell activity.
• To provide insights for novel cancer immunotherapy strategies and potential drug targets.

Main Methods:

• Systematic review and analysis of existing literature on polysaccharides and Th1/Th2 cell regulation in cancer.
• Focus on molecular mechanisms underlying polysaccharide interactions with Th1 and Th2 cells.
• Evaluation of how these interactions impact the tumor immune microenvironment.

Main Results:

• Polysaccharides demonstrate the ability to modulate the Th1/Th2 cell balance and their associated cytokine profiles.
• Restoration of Th1/Th2 equilibrium by polysaccharides can improve the anti-tumor immune response.
• This regulation contributes to a more favorable tumor immune microenvironment.

Conclusions:

• Polysaccharides offer a promising therapeutic approach for correcting Th1/Th2 imbalance in cancer.
• Understanding the molecular mechanisms of polysaccharide action can lead to new cancer immunotherapy targets.
• Targeting Th1/Th2 balance with polysaccharides may enhance anti-tumor immunity and delay tumor progression.
