Astragalus polysaccharide (APS) improves the immune function in diet-induced obese (DIO) mice

Area of Science:

• Immunology
• Pharmacology
• Traditional Chinese Medicine

Background:

• Obesity poses significant health risks, impairing immune function and complicating inflammation treatment.
• Traditional Chinese Medicine offers a holistic approach, focusing on overall well-being rather than just weight loss.
• Astragalus polysaccharide (APS), derived from Astragalus membranaceus, shows potential for improving obese individuals' health.

Purpose of the Study:

• To investigate the immunomodulatory effects of Astragalus polysaccharide (APS) in diet-induced obese (DIO) mice.
• To explore the dose-dependent impact of APS on obesity prevention and immune system regulation.
• To assess APS's influence on metabolic profiles and immune homeostasis in obese models.

Main Methods:

• Utilized a diet-induced obesity (DIO) mouse model.
• Administered varying concentrations of Astragalus polysaccharide (APS).
• Monitored body weight, blood glucose, lipid profiles, and immunological variables.

Main Results:

• A 4% APS concentration significantly reduced body weight in DIO mice; a 2% concentration showed a tendency to increase it.
• APS modulated blood glucose and lipid profiles, improving related factors.
• APS reactivated suppressed immune function in obese mice, regulating immunological variables and promoting homeostasis.

Conclusions:

• The immunomodulatory and obesity-preventive effects of APS are dose-dependent.
• A 4% concentration of APS demonstrated significant benefits in obesity management and immune modulation.
• Findings suggest APS as a potential therapeutic reference for obesity-related inflammatory conditions and immune dysregulation.
