IL33 and neoplasm: At present, it is well-established that these effects are mainly mediated by an increased recruitment of dendritic cells and/or enhancement of their anti-tumor activity through their dependence on IL-33, which might also contribute to explain the here reported increased counts in blood of circulating monocytes and NK-cells, in addition to ILC2, since these cell populations share in common the expression of the ST2 IL-33 receptor (50).
