Experimental details: Figure 3 Presence of IL-17-producing cells in the degenerated IVD tissues. Fifty IVD tissue samples (Group P, n = 20 and Group E, n = 30) from disc degeneration patients and 3 from scoliosis patients were analyzed. In Group P or the control group, there were few or no positive cells (data not shown). The representative results of group E are shown. (a), IL-17-producing cells were detected by a rabbit anti-IL-17 polyclonal antibody and a mouse anti-CD4 monoclonal Ab, followed by secondary staining with an Alexa 488-conjugated donkey anti-rabbit and an Alexa 568-conjugated donkey anti-mouse IgG. DAPI mounting medium was used for nuclear staining. (b), surface CCR6 expression on the cells was detected with a rabbit anti CD4 monoclonal Ab and a mouse anti-CCR6 monoclonal Ab, followed by secondary staining with an Alexa 488-conjugated donkey anti-rabbit and an Alexa 568-conjugated donkey anti-mouse IgG. DAPI mounting medium was used for nuclear staining. In the top panel, green and red represents the expression of IL-17 and CD4, respectively, and the double-stained cells represent the IL-17-producing cells. In the bottom panel, green and red represents the expression of CD4 and CCR6, respectively, and the double-stained cells demonstrate the surface expression of CCR6 on T lymphocytes.
