Interestingly, this finding was not repeated when the expression of the inflamed colonic mucosa of C. jejuni-infected patients was compared to that of healthy individuals, where HCAR2 and HCAR3 followed the same tendency of overexpression, though without reaching significance, thus indicating a possible role of these receptors specific to the development of inflammation in IBD. The gene discussed is HCAR2; the disease is inflammatory bowel disease.
