Effect of acupuncture on SERT expression in the DRN. a-c Representative images of SERT expression in the DRN. d Summary of SERT fluorescence intensity (FI, D) in the DRN following LPS administration. Data are expressed as percentage of control (normal). Acupuncture at ST41 markedly decreased SERT expression produced by LPS in the DRN. **P < 0.01 and ***P < 0.001 vs. control, ^### P < 0.001 vs. LPS, n = 3–4 per group. Scale bar = 50 μm
