Foxa2 controls Pdx1 gene expression in pancreatic beta-cells in vivo.
|

|
Prior in vitro analysis has suggested that the forkhead/winged helix transcription factor Foxa2 (formerly HNF-3beta) is a major upstream regulator of Pdx1, a homeobox gene essential for pancreatic development.
|

12145169
|
To analyze the Foxa2/Pdx1 regulatory cascade during pancreatic beta-cell differentiation, we used conditional gene ablation of Foxa2 in mice.
|
4 |
12145169
|
We demonstrated that the deletion of Foxa2 in beta-cell-specific knockout mice results in downregulation of Pdx1 mRNA and subsequent reduction of PDX-1 protein levels in islets.
|
5 |

|
These data represent the first in vivo demonstration that Foxa2 acts upstream of Pdx1 in the differentiated beta-cell.

FOXC2, a forkhead/winged helix transcription factor, represents a promising candidate gene for type 2 diabetes since transgenic mice that specifically overexpress this gene in adipocytes are lean and insulin sensitive.

Induction of FoxP3 and acquisition of T regulatory activity by stimulated human CD4+CD25- T cells.
|

14597769
|
CD4+CD25+ regulatory T (TR) cells have been described in both humans and mice.
|
9 |
14597769
|
Recently, the forkhead/winged helix transcription factor, FoxP3, has been shown to be important for the function of TR cells in mice.
|
10 |
14597769
|
In this study, human TR cells were examined and, in results similar to those of studies done in mice, expression of FoxP3 was found exclusively in CD4+CD25+ T cells and correlated with the suppressive activity of these cells.
|
11 |
14597769
|
In contrast to the mouse studies, activation of human CD4+CD25- T cells led to expression of FoxP3.
|
12 |
14597769
|
Expression of FoxP3 in activated human CD4+CD25+ cells also correlated with suppression of proliferation by these cells in freshly isolated CD4+CD25- T cells from the same donor.
|
13 |
14597769
|
Thus, in humans, during activation of CD4+CD25- T cells in an immune response, two populations of cells may arise, effector CD4+CD25+ and regulatory CD4+CD25+ T cells, with expression of FoxP3 correlated with regulatory activity.

Mutations of the forkhead/winged helix transcription factor FOXP3 gene on chromosome Xp11.23 cause a rare recessive monogenic disorder called IPEX (immune dysregulation, polyendocrinopathy, including type 1 diabetes, enteropathy, and X-linked syndrome).
|
15 |
15220219
|
FOXP3 is necessary for the differentiation of a key immune suppressive subset of T-cells, the CD4+CD25+ regulatory T-cells.

We show that effectors generated from murine islet-specific CD4 cells by TCR stimulation with IL-2 and TGF-beta1 have potent suppressive activity.

However, the adaptive population does acquire the X-linked forkhead/winged helix transcription factor, FoxP3, which is associated with regulatory T cell function and maintains expression in vivo.

In vivo, they eliminate Th1 cells in lymphoid tissues, where Fas/FasL interactions potentially play a role because Th1 cells persist when this pathway is blocked.

Cooperation of invariant NKT cells and CD4+CD25+ T regulatory cells in prevention of autoimmune diabetes in non-obese diabetic mice treated with alpha-galactosylceramide.
|

|
CD1d-restricted natural killer T (NKT) cells and CD4+CD25+ regulatory T (Treg) cells are two thymus-derived subsets of regulatory T cells that play an important role in the maintenance of self-tolerance.
|
33 |
18465023
|
Yet the functional changes of the two subsets of regulatory T cells in the development of diabetes in non-obese diabetic (NOD) mice remain unclear, and how NKT cells and CD4+CD25+ Treg cells cooperate functionally in the regulation of autoimmune diabetes is also uncertain.
|
34 |
18465023
|
We provide evidence that in NOD mice, an animal model of human type 1 diabetes, the functions of both NKT cells and CD4+CD25+ Treg cells decrease in an age-dependent manner.
|
35 |
18465023
|
We show that treatment with alpha-galactosylceramide increases the size of the CD4+CD25+ Treg cell compartment in NOD mice, and augments the expression of forkhead/winged helix transcription factor and the potency of CD4+CD25+ Treg cells to inhibit proliferation of CD4+CD25- T cells.
|
36 |
18465023
|
Our data indicate that NKT cells and CD4+CD25+ Treg cells might cooperate in the prevention of autoimmune diabetes in NOD mice treated with alpha-galactosylceramide.
|
37 |
18465023
|
Induced cooperation of NKT cells and CD4+CD25+ Treg cells could serve as a strategy to treat human autoimmune disease, such as type 1 diabetes.

Multiple studies have shown that thymus-derived naturally occurring Tregs constitutively express the forkhead/winged helix transcription factor FoxP3 in addition to high levels of CD25, the negative co-stimulatory molecule CTLA-4, and the glucocorticoid-induced TNF receptor-related protein GITR.
|
39 |
19120317
|
At variance, adaptive or induced Tregs acquire these phenotypic markers as they differentiate in the periphery, following adequate stimulation in the appropriate environment, together with their capacity to produce immunomodulatory cytokines (mainly, IL-4, IL-10 and TGF-beta) and to display regulatory capacities.

Moreover, data are presented that simultaneous blockade of CTLA4 and TGF-beta further impairs immunoregulatory circuits that control disease progression.
