From: Differential binding of chemokines to macrophages and neutrophils in the human inflamed synovium
Immunohistochemistry of CXCR2 in the synovium using immunoperoxidase and diaminobenzidine (brown) staining. (a) Section of rheumatoid synovium treated with a CXCR2 antibody. CXCR2 is expressed on macrophages in the intima. (b) Adjacent section to (a) treated with an anti-CD68 antibody. (c) CXCR2 is present in neutrophils in the rheumatoid synovium. (d) There was a lack of staining when sections were incubated with rabbit IgG instead of CXCR1 or CXCR2. Magnification × 380 (a), (b) and (d); magnification × 470 (c).
