Expression of IL-17 by immunohistochemistry. (A) Double-staining of IL-17 (black) and CD117+ mast cells (pink). (B) Double-staining of IL-17 (black) and CD68+ macrophages (pink). (C) Double-staining of IL-17 (black) and CD3+ T cells (pink). (D) Double-staining of IL-17 (black) and CD4 (pink). Representative examples are shown. In insets in parts (A) through (D), arrows indicate double-positive cells and arrowheads indicate single IL-17+ cells. The magnification of inset images are made digitally, and are 2× the magnification of the original figure which is made through a 400× magnification.
