Expression of Interleukin-26 is upregulated in inflammatory bowel disease

Figure 2 Immunohistochemical analyses of interleukin-26 in the inflamed mucosa of inflammatory bowel disease patients. A: Immunostaining for IL-26 in normal mucosa and inflamed mucosa of UC and CD. Pictures are shown from one of four independent samples with similar results. Magnification; upper panel × 200, lower panel × 400; B: Dual-colored immunofluorescence was used to determine the expression of IL-26 (green fluorescence) and CD4, CD56 and CD68 (red fluorescence) in inflamed mucosa of UC patients. Double-positive cells were detected by yellow fluorescence. Pictures are shown from one of four independent samples with similar results. IL: Interleukin; CD: Crohn’s disease; UC: Ulcerative colitis.
