Interestingly, we found that in Tslp−/− mice, e.c. HDM + IL-1β also induced the infiltration of eosinophils and basophils (Fig. 3e; see Supplementary Fig. 1c for cell counts comparison), as well as Th2 cytokine (particularly IL-13) expression in TCR-β+ cells in the dermis (Supplementary Fig. 4a), indicating that IL-1β is able to promote e.c. HDM-induce skin Th2 inflammation without the need of TSLP. Here, IL1B is linked to neoplasm.
