By contrast, expression of Il9 and Il4, known cytokine inducers of MMC and CTMC respectively [44, 45], showed a marked IL-33 dependent increase in gp130F/F antral tumours, with levels in gp130F/FIl33−/−compound mutants comparable to those of WT controls (Figure 5F; Figure 3E). Here, IL33 is linked to neoplasm.
