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>Macroscopic morphology, radiographic, and histopathological analysis of ankle joints. (a) Typical images of hind paws from each group after 28 days’ EA intervention. <i>n</i> = 12 per group. (b) Representative radiographic images of hind paws from each group after 28 days’ EA intervention. Red arrows indicate the bone erosion regions in the ankle joints, <i>n</i> = 12 per group. (c) HE staining of ankle joints from each group after 28 days’ EA intervention. Black arrows indicate the infiltrated inflammatory cells, <i>n</i> = 6 per group. Scale bar: 200 <i>μ</i>m. (d) HE staining score of each group.
