Programming of a pathogenic Th2 state by TSLP signaling in CD4+ T cells

Project description:Pathogenesis of allergic diseases including asthma is strongly associated with robust responses of allergen-specific Th2 cells, which produce high levels of IL-4, IL-5, IL-9, and IL-13. Despite evidence for pathogenic Th2 cells in the induction and propagation of allergic disorders, signals required for differentiation of such cells remain largely unknown. Thymic stromal lymphopoietin (TSLP) is a cytokine that is expressed upon epithelial injury, dysfunction or infection and is strongly implicated in the pathogenesis of atopic dermatitis (AD) and asthma. Although indirect regulation of Th2 differentiation via TSLP-stimulated dendritic cells well known, direct effects of TSLP on Th2 differentiation in vivo have not been rigorously analyzed. We show that TSLP may initiate Th2 response independent on IL-4 signal and increases sensitivity of CD4 cells to IL-4 stimulation inducing more robust expression of IL-4, IL-5, and IL-13 by human and mouse CD4 cells. This more potent effector state appears to be stably programmed in memory Th2 cells. As part of molecular mechanism, we demonstrate that TSLP and IL-4 signals induce distinctive genome wide alterations in activating histone modification (H3K27Ac, H3K36Me3, and H3K4Me3). We propose that TSLP acts in coordination with IL-4 to generate a more potent Th2 state that could underlie persistence and propagation of allergic disorders.

TSLP Expression: Analysis with a ZsGreen TSLP Reporter Mouse

Project description:Thymic stromal lymphopoietin (TSLP) is a type I cytokine that plays a central role in induction of allergic inflammatory responses. Its principal targets have been reported to be dendritic cells and / or CD4 T cells; epithelial cells are a principal source. We report here the development of a reporter mouse (TSLP-ZsG) in which a ZsGreen (ZsG)-encoding construct has been inserted by recombineering into a bacterial artificial chromosome (BAC) immediately at the translation initiating ATG of TSLP. The expression of ZsG by mice transgenic for the recombinant BAC appears to be a faithful surrogate for TSLP expression, particularly in keratinocytes and medullary thymic epithelials cells (mTECs). A comparison of gene expression in ZsG expressing and ZsG negative mTECs and cortical thymic epithelial cells, which are all ZsG negative, revealed that all three populations can be distinguished from one another. In particular ZsG (and TSLP) expressing mTECs and ZsG- mTECs are separable populations based on gene expression profiling. Little or no expression of ZsG is observed in bone marrow-derived mast cells or basophils or in CD45+ cells infiltrating TSLP/ZsG-expressing skin. Using the TSLP-ZsG reporter mouse, we show that TNFa and IL-4/IL-13 are potent inducers of TSLP expression by keratinocytes and that local activation of Th2 and Th1 cells induces keratinocyte TSLP expression. We suggest that the capacity of TSLP to both induce Th2 differentiation and to be induced by activated Th2 cells raises the possibility that TSLP may be involved in a positive feedback loop to enhance allergic inflammatory conditions.

Trenscriptome analysis of TSLP stimulated regulatory T cells

Project description:Regulatory T cells are indispensable for the immune homeostasis. Recent studies revealed the crucial roles of tissue factors; however, the roles of epithelial cell derived cytokine TSLP in the maturation of regulatory T cells are not adressed. Here, we report that TSLP activates mTOR signaling to mature regulatory T cells to maintain large intestine homeostasis.
