The damaged intestinal epithelium in IBD increases invasion of pathogenic and harmful bacteria, namely, “translocation” [34], recruiting a large number of macrophages, secreting Interleukin-1 (IL-1), IL-6, IL-12, IL-23 and tumor necrosis factor (TNF), and producing reactive oxygen species (ROS) (Figure 2) [35]. The gene discussed is IL6; the disease is inflammatory bowel disease.
