Acupuncture Alleviates Rheumatoid Arthritis by Immune-Network Modulation

Area of Science:

• Immunology
• Rheumatology
• Integrative Medicine

Background:

• Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease characterized by immune network imbalance.
• Acupuncture has shown therapeutic potential for RA, but its precise mechanisms require elucidation.
• Understanding acupuncture's immunomodulatory effects is crucial for RA treatment.

Purpose of the Study:

• To investigate the mechanisms by which manual acupuncture (MA) modulates the immune network in a rat model of RA.
• To clarify how MA influences innate and adaptive immunity in the context of RA.
• To identify key cellular targets of MA in RA treatment.

Main Methods:

• Utilized a complete Freund's adjuvant (CFA)-induced arthritis rat model to simulate RA.
• Administered manual acupuncture (MA) and assessed its effects on inflammation and pain.
• Analyzed changes in innate and adaptive immune cytokines using cell-cell communication (CCC) networks.

Main Results:

• MA significantly reduced inflammation and pain in arthritic joints.
• MA modulated key innate immune cytokines (e.g., IL-1β, TNF-α) and adaptive immune cytokines (e.g., IL-2, IFN-γ, IL-4, IL-17).
• CCC network analysis revealed MA's role in enhancing immune networks during early RA and normalizing them in later stages, targeting monocytes/macrophages, endothelial cells, T_H1, T_H2, and B cells.

Conclusions:

• Manual acupuncture effectively treats RA by modulating the immune network.
• MA stimulates both innate and adaptive immune responses, aiding in RA recovery.
• MA targets specific immune cells, offering a potential therapeutic strategy for rheumatoid arthritis.
