In order to confirm that RORα deletion results in ablation of ILC2s, we analysed the number and function of T cells and ILCs within the colons of untreated (Figure S5) Rorαfl/flIl7rCreT/+ and Rorα+/+Il7rCreT/+ mice, compared to tumour-bearing mice (Figure S6 and Figure 3E,F). Here, RORA is linked to neoplasm.
