Figure 1From: The expression of the receptor for advanced glycation end-products (RAGE) in RA-FLS is induced by IL-17 via Act-1Immunohistochemical staining of RAGE, Act1 and IL-17. (a) The synovial tissue sections from patients with rheumatoid arthritis and osteoarthritis were stained with antibodies to RAGE, Act-1, IL-17, and H&E or an isotype-control antibody. The brown color shows the target. (b) Dual immunohistochemistry labeling using antibody RAGE and CD55 (for fibroblast like synoviocytes) or CD68 (for macrophages). All tissues were counterstained with hematoxylin (original magnification, x400).Back to article page
