In comparison, in the NC vs. ET and ET vs. CM groups, the pathways associated with inflammation and immune system were detected, such as inflammatory mediator regulation of the TRP channels, the IL-17 signaling pathway, the Toll-like receptor signaling pathway, inflammatory bowel disease, and Th17 cell differentiation, of which three DEPs (Hnf4a, Hsp90aa1, and IlL) were upregulated in the ET group, while downregulated in the CM group. Here, HNF4A is linked to inflammatory bowel disease.
