Graft-infiltrating cells (GIC) recovered from TH1-transfused animals contained large numbers of graft-reactive IL-2-producing cells (68-269/10(6) GIC), but no LDA-detectable IL-4-producing cells.

Infiltrating cells recovered from TH1-transfused allografts contained large numbers of graft-reactive (109-1458/10(6) GIC), LDA-detectable, IL-4-producing cells--indicating that the TH2 cells had arrived at the graft-but promoted acute allograft rejection rather than allograft acceptance.

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.

|
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.

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

|
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.
