Cutting edge: TGF-beta inhibits Th type 2 development through inhibition of GATA-3 expression.

چکیده
TGF-beta is an important immunomodulatory cytokine that can inhibit differentiation of effector T cells. In this report, we address the molecular mechanisms through which TGF-beta inhibits differentiation of CD4(+) cells into Th type 2 cells. We demonstrate that TGF-beta inhibits GATA-3 expression in developing Th cells. We also show that inhibition of GATA-3 expression by TGF-beta is a major mechanism of inhibition of Th2 differentiation by TGF-beta as ectopic expression of GATA-3 in developing T cells overcomes the ability of TGF-beta to inhibit Th2 differentiation. TGF-beta likely inhibits GATA-3 expression at the transcriptional level and does so without interfering with IL-4 signaling.

Physical and Functional Interaction between GATA-3 and Smad3 Allows TGF-β Regulation of GATA Target Genes
BACKGROUND Members of the GATA family of zinc finger transcription factors are genetically controlled "master" regulators of development in the hematopoietic and nervous systems. Whether GATA factors also serve to integrate epigenetic signals on target promoters is, however, unknown. The transforming growth factor-beta (TGF-beta) superfamily is a large group of phylogenetically conserved secret...
متن کاملMechanism of Transforming Growth Factor β–induced Inhibition of T Helper Type 1 Differentiation
Regulation by transforming growth factor (TGF)-beta plays an important role in immune homeostasis. TGF-beta inhibits T cell functions by blocking both proliferation and differentiation. Here we show that TGF-beta blocks Th1 differentiation by inhibiting the expression of T-bet, the apparent masterregulator of T helper (Th)1 differentiation. Restoration of T-bet expression through retroviral tra...
متن کاملpRb is necessary for inhibition of N-myc expression by TGF-beta 1 in embryonic lung organ cultures.
The beta type transforming growth factors (TGF-beta) are potent inhibitors of epithelial cell proliferation, and data suggest that growth inhibition by TGF-beta 1 is mediated through suppression of Myc family genes in certain cell types. Indirect evidence has indicated that the product of the retinoblastoma gene (pRb) may also be involved in this pathway. Previously, we have shown that TGF-beta...
متن کاملTransforming Growth Factor β Blocks Tec Kinase Phosphorylation, Ca2+ Influx, and NFATc Translocation Causing Inhibition of T Cell Differentiation
Transforming growth factor (TGF)-beta inhibits T cell proliferation and differentiation. TGF-beta has been shown to inhibit the expression of transcription factors such as GATA-3 and T-bet that play important roles in T cell differentiation. Here we show that TGF-beta inhibits T cell differentiation at a more proximal step. An early event during T cell activation is increased intracellular calc...
متن کاملTargeting Transforming Growth Factor-Beta1 (TGF-β1) Inhibits Tumorigenesis of Anaplastic Thyroid Carcinoma Cells Through ERK1/2-NF-κB-PUMA Signaling
BACKGROUND The transforming growth factor-beta (TGF-β) signaling pathway plays a critical role in promoting tumor growth. TGF-β1was found to be overexpressed in anaplastic thyroid cancer (ATC). We therefore tested our hypothesis that targeting TGF-β1 inhibits tumorigenesis of ATC cells. MATERIAL AND METHODS Effects of TGF-β1 stimulation or TGF-β1 inhibition by small interfering RNA (TGF-β1siRNA...
