T-bet controls autoaggressive CD8 lymphocyte responses in type 1 diabetes.

|
The T-box transcription factor T-bet is known to control lineage commitment and interferon-gamma production by T helper 1 (Th1) CD4 lymphocytes.

We report here that T-bet is essential for development of CD8 lymphocyte-dependent autoimmune diabetes (type 1 diabetes [T1D]) in the rat insulin promoter-lymphocytic choriomeningitis virus (LCMV) transgenic model for virally induced T1D.

|
In the absence of T-bet, autoaggressive (anti-LCMV) CD8 lymphocytes were reduced in number and produced less IFN-gamma, but increased IL-2 compared with controls.
|

|
Further analysis showed that T-bet intrinsically controls the generation, but not apoptosis, maintenance, or secondary expansion of antiviral effector/memory CD8 lymphocytes.

In the pancreas of VIP-treated animals, regulatory T cell markers predominate, as indicated by the upregulation of FoxP3 and transforming growth factor-beta (TGF-beta), and the downregulation of the transcription factor, T-bet.

The transcription factor T-cell factor 7-like 2 (TCF7L2) confers type 2 diabetes risk mainly through impaired insulin secretion, perturbed incretin effect and reduced beta-cell survival.

TCF7L2 binds to 3646 gene promoters in INS-1 cells in high or low glucose, including Tp53, Pten, Uggt1, Adamts9 and Fto.
|

|
SiRNA-mediated reduction in TCF7L2 activity resulted in increased apoptosis and increased expression of Tp53, which resulted in elevated p53 protein activity and an increased expression of the p53 target gene Tp53inp1 (encoding p53-induced-nuclear-protein 1).
|

|
These results identify the p53-p53INP1 pathway as a molecular mechanism through which TCF7L2 may affect beta-cell survival and established a molecular link between Tcf7l2 and two type 2 diabetes-associated genes, Tp53inp1 and Adamts9.

IL-21 promotes CD8+ CTL activity via the transcription factor T-bet.
|
12 |
23479229
|
IL-21 is an IL-2 family cytokine and a growth factor for multiple lymphocyte effector lineages, including cytotoxic CD8(+) T cells.
|
13 |
23479229
|
This is most likely the result of impaired CD8(+) CTL function in the absence of IL-21 signaling.
|
14 |
23479229
|
Currently, the mechanisms by which IL-21 promotes CTL differentiation in CD8(+) T cells remain unclear, particularly the identity of the relevant transcription factor(s).
|
15 |
23479229
|
We demonstrate that IL-21 induces the expression of the transcription factor T-bet in CD8(+) T cells, predominantly via STAT1, and that T-bet is required for the induction of cytolytic molecules, including perforin and granzyme B in response to IL-21.
|
16 |
23479229
|
Finally, we show that IL-21-induced CTL function is T-bet dependent, as T-bet deficiency results in defective IL-21-dependent cytotoxicity in CD8(+) T cells in vitro and in vivo.
|
17 |
23479229
|
Thus, IL-21 drives CD8(+) CTL differentiation via the actions of the transcription factor T-bet.

We report that mice deficient in the immune cell transcription factor T-bet have lower energy expenditure and increased visceral fat compared with wild-type mice, yet paradoxically are more insulin sensitive.
