“…IFN-γ blockade in dextran sodium sulfate-colitis mouse models had increased angiogenesis accompanied with improved vascular barrier function and reduced colonic inflammation [ 112 ]. Fontolizumab, an anti-IFN-γ antibody, increased the rate of clinical response in individuals with refractory CD, after receiving two doses of fontolizumab intravenously on Day 56 [ 113 ].…”

Inflammatory bowel disease (IBD) is an immune-mediated inflammatory condition involving both the innate and adaptive immune systems. Recently, the role of intestinal fungal flora and their downstream immune pathways has been highlighted in the pathogenesis of IBD. Cytokines as primary immune mediators require a delicate balance for maintaining intestinal homeostasis. Although most cytokines have a predictable role in either amplifying or attenuating inflammation in IBD, a few cytokines have shown a dual function in the inflammatory state of the intestine. Some of these dual-faced cytokines are also involved in mucosal anti-microbial defense pathways, particularly against intestinal fungal residents. Here, we reviewed the role of these cytokines in IBD pathogenesis to achieve a better understanding of the fungal interactions in the development of IBD.
