IL1B and neoplasm: In one hand, we show that first, the depletion of IL-1β-expressing neutrophils and monocytes/macrophages does not impact TSLP production; second, the supplement of IL-1β does not induce TSLP expression, which is in contrast to a previous report showing that in vitro IL-1β induces TSLP in reconstructed human epidermis culture43; and third, the supplement of IL-1β enhances the e.c. HDM sensitization in Tslp−/− mice similarly as in WT mice, suggesting that the effect of IL-1β in promoting skin allergic sensitization is TSLP-independent.
