LRRC19 and colitis: WT/WT chimeras (WT bone marrow [BM] donor cells transplanted into lethally irradiated WT recipients), but not cohoused KO/ko chimeras (Lrrc19 KO BM donor cells transplanted into lethally irradiated Lrrc19 KO recipients), responded effectively to DSS-induced colitis, further confirming the role of LRRC19 in colitis (data not shown).
