Electroacupuncture (EA), a fascinating fusion of ancient acupuncture principles and modern electrical stimulation, has garnered attention for its therapeutic potential. Beyond pain management, EA’s effects extend to the molecular level, influencing neural networks, inflammation, and cellular responses. In this comprehensive article, we explore the intricate molecular mechanisms behind EA.
1. Neuronal Activation and Inflammation Control
Neuroanatomical Basis
- EA involves stimulating specific acupoints using electrical impulses.
- Recent research has identified a set of neurons expressing the protein Prokr2 as crucial mediators of EA’s anti-inflammatory effects in a mouse model of sepsis1.
- These neurons play a pivotal role in reining in the unbridled inflammatory responses characteristic of lethal sepsis.
Acupoints and Controversy
- Acupoints are strategically chosen based on individual responses.
- The Zusanli (ST36) acupoint, located below the knee, is frequently stimulated for inflammation relief.
- However, the intensity of EA at ST36 can yield opposing effects: high-intensity EA activates the sympathetic nervous system (fight-or-flight response), while low-intensity stimulation activates the parasympathetic system (rest and regulation).
2. Therapeutic Implications
Sepsis Management
- Sepsis, a life-threatening condition resulting from uncontrolled inflammatory reactions to infection, remains a major cause of hospital deaths.
- Low-intensity EA at ST36 activates the vagal nerve, which communicates with the adrenal glands to curb severe inflammation.
- EA offers a potential solution for managing sepsis and other inflammatory diseases.
Muscle Repair and Myostatin Suppression
- EA suppresses myostatin expression, promoting satellite cell-related proliferation and skeletal muscle repair2.
- The Aig1l gene likely plays a key role in EA’s efficacy.
3. Neuroprotection in Parkinson’s Disease
Multifaceted Mechanisms
- EA’s neuroprotective effects in Parkinson’s disease (PD) involve various molecular pathways:
- Anti-oxidant stress response
- Anti-neuroinflammatory response
- Up-regulation of neurotrophic factors
- Reduction of nerve cell apoptosis
- Endoplasmic reticulum stress modulation
- Ubiquitin-proteasome system enhancement
- Anti-excitatory toxicity response
- Autophagy activation
- Gut microbiota modulation3.

4. Epigenetic Insights
DNA Methylation and Histone Acetylation
- EA induces epigenetic changes, altering DNA methylation patterns and histone acetylation.
- These modifications impact gene expression and cellular responses.
5. Future Prospects
As our understanding of EA’s molecular effects deepens, we anticipate breakthroughs in personalized treatments. Integrating ancient wisdom with cutting-edge science, EA continues to illuminate new pathways for healing and well-being.
In summary, EA transcends time and culture, engaging intricate molecular networks to promote health. Whether it’s inflammation control, muscle repair, or neuroprotection, EA stands as a testament to the harmonious interplay of tradition and innovation.
