Fig. 5 — EA regulated co-expression of CXCL13/CXCR5. A Double immunostaining of CXCL13 and CXCR5 increased in IS group and decreased by EA. Scale bar: 100/50um. B, D Immunofluorescence staining showed the CXCL13 were primarily colocalized within neuron (NeuN positive), rarely within astrocytes (GFAP positive) and microglia (Iba1 positive) in the Sp5C site. C, E Immunofluorescence staining showed the CXCR5 were primarily colocalized within neuron (NeuN positive), rarely within astrocytes (GFAP positive) and microglia (Iba1 positive) in the Sp5C site. Scale bar: 100/20 µm. EA: electroacupuncture; IS: inflammatory soup
