NFKB1 and gastroenteritis: Mechanistically, overexpressed DPEP2 inhibited the transduction of inflammatory signals by resisting MAK3K7 in inactivated macrophages, whereas DPEP2 degradation by activated Trim32 resulted in strong activation of NF-κB and p38 MAPK signaling via the release of MAK3K7 in proinflammatory macrophages during the development of intestinal inflammation.
