Ikaros is a regulator of Il10 expression in CD4+ T cells.
|

|
Here we show that Ikaros, a zinc finger DNA-binding protein, plays an important role in the regulation of Il10 in murine CD4(+) T cells.

|
Upon initial stimulation of the TCR, T cells deficient in Ikaros express significantly lower levels of IL-10 compared with wild-type T cells.

|
In addition, under Th2 skewing conditions, which induce IL-10 production by wild-type T cells, Ikaros null T cells are unable to properly differentiate, producing only low levels of IL-10.
|
| 5 |

|
Expression of a dominant-negative isoform of Ikaros in wild-type Th2 cells represses IL-10 production but does not significantly alter expression levels of the genes encoding the transcription factors GATA-3 and T-bet.
|

|
Furthermore, expression of Ikaros in Ikaros null T cells restores expression of the Th2 cytokines IL-10 and IL-4 while reducing production of the Th1 cytokine, IFN-gamma.
|
| 7 |

|
Coexpression of Ikaros and GATA-3 further increases IL-10 production, showing that these two factors have an additive effect on activating Il10 expression.
|
| 8 |

|
Finally, we show that Ikaros binds to conserved regulatory regions of the Il10 gene locus in Th2 cells, supporting a direct role for Ikaros in Il10 expression.
|

|
Thus, we provide evidence for Ikaros as a regulator of Il10 and Ifng gene expression and suggest a role for Ikaros in directing lineage-specific cytokine gene activation and repression.

We used a gene panel of regulatory/inflammatory molecules (FOXP3, GATA3, IL10, TGFB1, TGFBR1/ TBX21, TNF and IFNG) to investigate the gene expression profile in peripheral blood mononuclear cells of renal-transplanted individuals experiencing OT compared to transplanted individuals not displaying OT and healthy individuals (HI).

|
OT subjects showed a predominant regulatory (REG) profile with higher gene expression of GATA3, FOXP3, TGFB1 and TGFB receptor 1 compared to the other groups.
