The transcription factor GATA3 actively represses RUNX3 protein-regulated production of interferon-gamma.
|

|
The transcription factor GATA3 is crucial for the differentiation of naive CD4(+) T cells into T helper 2 (Th2) cells.

|
Here, we show that deletion of Gata3 allowed the appearance of interferon-gamma (IFN-gamma)-producing cells in the absence of interleukin-12 (IL-12) and IFN-gamma.

|
Such IFN-gamma production was transcription factor T-bet independent.

|
Another T-box-containing transcription factor Eomes, but not T-bet, was induced both in GATA3-deficient CD4(+) T cells differentiated under Th2 cell conditions and in Th2 cells with enforced Runx3 expression, contributing to IFN-gamma production.

|
GATA3 overexpression blocked Runx3-mediated Eomes induction and IFN-gamma production, and GATA3 protein physically interacted with Runx3 protein.
|

|
Furthermore, we found that Runx3 directly bound to multiple regulatory elements of the Ifng gene and that blocking Runx3 function in either Th1 or GATA3-deficient "Th2" cells results in diminished IFN-gamma production by these cells.

|
Thus, the Runx3-mediated pathway, actively suppressed by GATA3, induces IFN-gamma production in a STAT4- and T-bet-independent manner.

|
On the other hand, GATA3 inhibits T(h)1 cell differentiation by preventing up-regulation of IL-12 receptor β2 and STAT4 (signal transducer and activator of transcription 4) and neutralization of Runx3 (runt-related transcription factor 3) function through protein-protein interaction.

GATA3 may also directly act on the Ifng gene.
