e, f, Atg16L1-deficient chimaeric mice given 5% DSS in drinking water were intraperitoneally injected with both anti-IL-1b and anti- IL-18 neutralizing antibodies (squares; n55) or isotype control IgG (circles;n55) at days 1, 3, 5 and 7. The survival (e) and weight loss (f) of each mouse genotype were plotted.
