Electroacupuncture Alleviates Pain Responses and Inflammation in Collagen-Induced Arthritis Rats via Suppressing the TLR2/4-MyD88-NF-<i>κ</i>B Signaling Pathway

<div>EA intervention decreased the expression of TLR2 and TLR4 on synovial fibroblasts and macrophages. (a) Synovium sections were double immunofluorescence stained for TLR2 or TLR4 and CD68 (macrophages marker) or Vimentin (fibroblasts marker), respectively; TLR2 and TLR4 immunopositive cells appear in green color, CD68 and Vimentin immunopositive cells appear in red color, and colabled cells appear in yellow color. The magnification of immunofluorescent images is 200x. (b) The number of double staining cells of TLR2 or TLR4 and CD68 or Vimentin.
