Electroacupuncture Alleviates Pain Responses and Inflammation in Collagen‐Induced Arthritis Rats via Suppressing the TLR2/4‐MyD88‐NF‐κB Signaling Pathway

Repeated EA stimulation at ST36 and SP6 can effectively relieve joint pain and synovial inflammation caused by RA in CIA rats. The analgesic and anti-inflammatory effect of EA may be closely related to the inhibition of innate immune responses driven by the TLR2/4-MyD88-NF-κB signaling pathway in the synovium.
