T-bet-/- RAG2-/- ulcerative colitis: the role of T-bet as a peacekeeper of host-commensal relationships

Abstract

Inflammatory bowel disease is a disease that reflects a disequilibrium in host-commensal homeostasis. T-bet-/-xRAG2-/- deficient mice develop a spontaneous juvenile ulcerative colitis resulting from a pro-inflammatory response to the commensal microbiota that is dendritic cell and TNF-alpha driven [schematized in Fig. 1]. The TRUC (T-bet-/- RAG2-/- ulcerative colitis) model is discussed in the broader context of the adaptive and innate immune mechanisms that regulate host-commensal relationships within the intestine.
