DDX53 and neoplasm: We not only applied IL-33 pre-incubated eosinophils into CT26 tumor-bearing ∆dblGATA-1 mice i.v., but also injected IL-33 i.p. into ∆dblGATA-1 mice repopulated with IL-5 Eos and we detected reduced tumor growth (Supplementary Fig. 5A-B), but, unlike in Figure 4h, this time the number of tumor-infiltrated eosinophils was not significatly increased (i.p. IL-33 vs. i.p. vehicle [PBS], Supplementary Fig. 5 C).
