ITGAX and infection: We observed a slight increase in the numbers of ILC3, defined as lin−CD90+RORγt+ cells (see S2 Fig for gating strategy), in the colon of WT and CD11c-MyDON mice 4 days after infection with C. rodentium, while ILC3 numbers in MyDOFF and LysM-MyDON mice remained on a lower level (Fig 1D).
