What cells are affected by inflammatory bowel disease?
The intestinal epithelium and Paneth cells in IBD. Paneth cells are a further IEC type that plays an important role in mucosal homeostasis, and, if functionally impaired, is thought to contribute to IBD. 47 Paneth cells reside at the base of small intestinal crypts and secrete AMPs as well as inflammatory mediators.

Both illnesses involved an abnormal response to the body’s immune system.
What type of hypersensitivity is inflammatory bowel disease?
Type IV hypersensitivity is a delayed and cell-mediated reactions and is mediated by special immune cells such as a macrophage and T cell. This reaction usually takes from several hr to several days to develop an allergic response.
What immune cells are involved in Crohn’s disease?

How are endoscopies used to diagnose chronic inflammatory diseases in dogs?
When an endoscope is used, a tiny biopsy instrument will be used to take small samples of the lining or mucosa of the affected organ. The tissue biopsies will be sent to a veterinary pathologist for diagnosis. The pathologist will give a descriptive diagnosis to the syndrome, depending on the main type of inflammatory cells present in the biopsies.
