Notably, we observed no signs of colitis in Smarca4ΔILC3 mice by the age of 8 weeks as indicated by similar level of neutrophil infiltration, in spite of increased T-cell activation probably due to defective function of Tregs in the absence of Brg1 (Figs. S1b, c, S4f, g). Here, SMARCA4 is linked to colitis.
