a The colonic tissue was collected from PI-IBS patient by colonic endoscopic biopsy and processed into frozen sections, followed by immunofluorescent staining with anti-δ1/δ2 monoclonal antibody. Under laser scanning confocal microscope (200×), the intestinal Vδ1 γδ T cells from PI-IBS patients significantly increased while Vδ2 γδ T cells decreased compared with that from control group, p < 0.01. Representative graph were shown in the current figure
