abstractText | Thymic stromal lymphopoietin (TSLP) has emerged as a key initiator in Th2 immune responses, but the TSLP-driven immune cascade leading to Th2 initiation remains to be delineated. Here, by dissecting the cellular network triggered by mouse skin TSLP in vivo, we uncover that TSLP-promoted IL-4 induction in CD4(+) T cells in skin-draining lymph nodes is driven by an orchestrated ''DC-T-Baso-T'' cascade, which represents a sequential cooperation of dendritic cells (DCs), CD4(+) T cells and basophils. Moreover, we reveal that TSLP-activated DCs prime naive CD4(+) T cells to produce IL-3 via OX40L signalling and demonstrate that the OX40L-IL-3 axis has a critical role in mediating basophil recruitment, CD4(+) T-cell expansion and Th2 priming. These findings thus add novel insights into the cellular network and signal axis underlying the initiation of Th2 immune responses. |
