Striking Similarity: GATA-3 Regulates ILC2 and Th2 Cells

Protein kinase A regulates GATA-3-dependent activation of IL-5 gene expression in Th2 cells.

Treatment of Th cells with compounds that elevate cAMP levels augments Th2-type lymphokine expression, in particular the synthesis of IL-5. Using primary murine CD4(+) T lymphocytes, we show in this study that inhibition of protein kinase A (PKA) activity in Th2 effector cells impairs IL-5 synthesis, whereas the expression of PKA catalytic subunit alpha enhances IL-5 synthesis in Th0 cells. In ...

GATA-3 - not just for Th2 cells anymore.

GATA-3 was first cloned as a T cell specific transcription factor in 1991 and its importance in the transcriptional control of T helper type 2 cell (Th2) differentiation was established in the mid to late 90's. A role for GATA-3 during thymic development has long implied by its continuous and regulated expression through out T lineage development, but the absolute requirement for GATA-3 during ...

Different Expressions of Specific Transcription Factors of Th1 (T-bet) and Th2 cells (GATA-3) by Peripheral Blood Mononuclear Cells From Patients With Multiple Sclerosis

Introduction: Multiple Sclerosis (MS) is an inflammatory disorder caused by self-reactive Th1 lymphocytes, while Th2 cells may confer protection. The Th1 and Th2 cell differentiation are regulated by specific transcription factors, especially T-bet and GATA-3, respectively. This investigation aimed to measure the T-bet and GATA-3 expression by Peripheral Blood Mononuclear Cells (PBMCs) obtained...

Th2 cells and GATA-3 in asthma: new insights into the regulation of airway inflammation.

Regulation of Th2 cytokine expression in NKT cells: unconventional use of Stat6, GATA-3, and NFAT2.

NKT cells are unique in that they can produce high levels of both Th1 and Th2 cytokines, yet little is known about how NKT cells control the transcription of Th2 cytokines. The expression of IL-4 by NKT cells is independent of the Th2-associated transcription factor Stat6. We have found that Stat6 is critical for the expression of IL-5, IL-10, and IL-13 by NKT cells. However, the Th2 cell-assoc...
