Sections from the pancreata of these injected mice were stained for cytokines (tumor necrosis factor alpha [TNF-alpha], interferon gamma [IFN-gamma], CD1d, interleukin 2 [IL-2], IL-4, IL-6, IL-10, and IL-12).

A subset of CD161 (NK1) T cells express an invariant Valpha14Jalpha281 TCR-alpha chain (Valpha(invt) T cells) and produce Th2 and Th1 cytokines rapidly in response to CD1d, but their physiological function(s) remain unclear.

|
First, they are restricted by a nonclassical MHC class I molecule, CD1d, which presents glycolipids; second, their TCR repertoire is very limited.
|
6 |
11907079
|
After stimulation by their TCR, NKT cells rapidly release large amounts of cytokines, such as IL-4 and IFN-gamma.
|

|
Analysis of cytokine production by NKT cells from splanchnic lymph nodes reveals that they produce at least as much IL-4 as IFN-gamma, in contrast to NKT cells from other organs (spleen, liver, and peripheral lymph nodes), which produce much more IFN-gamma than IL-4.

Defects in IL-4-producing CD1d-autoreactive NKT cells have been implicated in numerous Th1-mediated autoimmune diseases, including diabetes, multiple sclerosis, rheumatoid arthritis, lupus, and systemic sclerosis.
|
10 |
12235110
|
Particular attention has been focused on autoimmune insulin-dependent diabetes mellitus (IDDM) because nonobese diabetic (NOD) mice and humans with IDDM are both reported to express severe deficiencies in the frequency and Th2 functions of NKT cells.
|
11 |
12235110
|
We have now devised a direct, highly specific CD1d tetramer-based methodology to test whether humans with IDDM have associated NKT cell defects.
|
12 |
12235110
|
Surprisingly, although we find marked and stable differences in NKT cells between individuals, our study of IDDM patients and healthy controls, including discordant twin pairs, demonstrates that NKT cell frequency and IL-4 production are conserved during the course of IDDM.

CD1d-reactive natural killer T (NKT) cells can rapidly produce T helper type 1 (Th1) and/or Th2 cytokines, can activate antigen-presenting cell (APC) interleukin-12 (IL-12) production, and are implicated in the regulation of adaptive immune responses.
|

|
EMCV-D resistance depends on IL-12-mediated interferon-gamma (IFN-gamma) production.
|
20 |

Interleukin-4 but not interleukin-10 protects against spontaneous and recurrent type 1 diabetes by activated CD1d-restricted invariant natural killer T-cells.
|
25 |
15111500
|
Although interleukin (IL)-4 and IL-10 have been implicated in alpha-GalCer-induced protection from type 1 diabetes, a precise role for these cytokines in iNKT cell regulation of susceptibility to type 1 diabetes has not been identified.
|
26 |
15111500
|
Here we use NOD.IL-4(-/-) and NOD.IL-10(-/-) knockout mice to further evaluate the roles of IL-4 and IL-10 in alpha-GalCer-induced protection from type 1 diabetes.
|
27 |
15111500
|
We found that IL-4 but not IL-10 expression mediates protection against spontaneous type 1 diabetes, recurrent type 1 diabetes, and prolonged syngeneic islet graft function.
|
28 |
15111500
|
Increased transforming growth factor-beta gene expression in pancreatic lymph nodes may be involved in alpha-GalCer-mediated protection in NOD.IL-10(-/-) knockout mice.
|
29 |
15111500
|
Unlike the requirement of IL-7 and IL-15 to maintain iNKT cell homeostasis, IL-4 and IL-10 are not required for alpha-GalCer-induced iNKT cell expansion and/or survival.
|

|
To test this hypothesis, we transgenically overexpressed CD1d molecules under the control of the insulin promoter within the pancreatic islets of NOD mice (insCD1d).
|
31 |
15322171
|
We now show that overexpression in NOD mice of CD1d-restricted TCR Valpha3.2(+)Vbeta9(+) NKT cells producing high levels of IFN-gamma but low amounts of IL-4 leads to prevention of type 1 diabetes, demonstrating a role for nonclassical CD1d-restricted NKT cells in the regulation of autoimmune diabetes.
|

|
Most NKT cells express both an invariant T cell antigen receptor and the NK cell receptor NK1.1, and are referred to as invariant NKT cells.
|
33 |
15833265
|
This invariant T cell receptor is restricted to interactions with glycolipids presented by the non-classical MHC, CD1d.
|
34 |
15833265
|
These NKT cells rapidly produce high levels of interleukin (IL)-2, IFN-gamma, TNF-alpha, and IL-4 upon stimulation through their TCR.
|

|
Restoring the numerical and/or functional deficiency of iNKT cells in NOD mice by either treatment with alpha-galactosylceramide, transgenic induction of Valpha14-Jalpha18 expression, or transgenic expression of CD1d in NOD islets under the control of the human insulin promoter confers protection from T1D in these mice.

Lack of chemokine receptor CCR5 promotes murine fulminant liver failure by preventing the apoptosis of activated CD1d-restricted NKT cells.
|
37 |
15944310
|
In this study, we demonstrate that CCR5 deficiency promotes the development of acute FLF in mice following Con A administration by preventing activated hepatic CD1d-restricted NKT cells (but not conventional T cells) from dying from activation-induced apoptosis.
|
38 |
15944310
|
The resistance of CCR5-deficient NKT cells from activation-induced apoptosis following Con A administration is not due to a defective Fas-driven death pathway.
|
39 |
15944310
|
Moreover, FLF in CCR5-deficient mice also correlated with hepatic CCR5-deficient NKT cells, producing more IL-4, but not IFN-gamma, relative to wild-type NKT cells.

From 451 T cell clones from control and diabetic PLN, we derived 55 iNKT cells by two methods and analyzed function by cytokine secretion. iNKT cell clones isolated from control PLN secreted IL-4 and IFN-gamma upon TCR stimulation.
|
45 |
16177088
|
For type 1a diabetic subjects, PLN iNKT cell clones from three samples secreted IFN-gamma and no IL-4.
|
46 |
16177088
|
From normal and diabetic PLN, one-third of CD1d tetramer+-sorted T cell clones were reactive with CD1d transfectants or proliferated/secreted cytokine in response to alpha-galactosylceramide-pulsed PBMCs; tetramer-staining T cell clones from diabetic PLN did not secrete IL-4.
|

|
Unlike conventional T cells that recognize peptides in association with major histocompatibility complex (MHC), NKT cells recognize glycolipid antigens presented by the non-polymorphic MHC class I-like protein, CD1d.
|
48 |
16178791
|
Recently, we and other groups have demonstrated that administration of glycolipid ligands such as alpha-galactosylceramide (alpha-GC ) or its sphingosine truncated derivative, OCH suppressed autoimmune diseases such as experimental autoimmune encephalomyelitis (EAE), diabetes in NOD mice and collagen-induced arthritis (CIA) by inducing T helper (Th) 2 bias of autoimmune T cells.
|
49 |
16178791
|
OCH is a unique ligand to stimulate NKT cells to selectively produce Th2 cytokines whereas alpha-GC induces both interleukin (IL)-4 and interferon (IFN)-gamma, and is more beneficial for treatment of a wide variety of Th1-mediated autoimmune diseases.

The non-classical antigen presenting molecule CD1d presents lipids and glycolipids to this highly specialized subset of T lymphocytes found in both humans and mice.
|
51 |
16505600
|
iNKT cells are a unique subset of CD1-restricted T lymphocytes that express T cell receptor (TCR) and some NK receptors. iNKT cells express an invariant TCRalpha chain composed of Valpha14-Jalpha18 segments in mice and Valpha24-Jalpha18 segments in humans associated with TCRbeta chains using a restricted set of Vbeta. iNKT cells recognize glycolipid antigens such as alpha-galactosylceramide (alpha-GC) presented by CD1d, non-pormorphic MHC class I-like molecule, and rapidly secrete large amounts of cytokines including IL-4 and IFN-gamma upon activation.

|
Interaction of antigen-presenting cell CD1d with distinct natural killer T-cell ("NKT") populations can induce rapid gamma interferon (IFN-gamma) production and NK-cell activation.
|
53 |
16809320
|
However, this was not reflected in the relative levels of NK-cell activation but rather by the responses of both CD4(+) and CD8(+) T-cell populations.
|
54 |
16809320
|
Repeated EMCV infection in vitro induced less IFN-gamma and alpha interferon (IFN-alpha) from CD1d-deficient splenocytes than with the wild type.

Here we show that antibodies to CD1d, when given during early thymic development, induce specific increases in surface TCR of developing NOD and C57BL/6 CD4(+)CD8(+) (DP) invariant NKT (iNKT) cells.

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.
|
76 |
18465023
|
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.
|
77 |
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.
|
78 |
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.
|
79 |
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.
|
80 |
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.
|
81 |
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.

|
The different iNKT cell effects are mediated through distinct mechanisms and activation of different molecular pathways within the DC: CD1d signaling and activation of the ERK1/2 pathway for the tolerogenic action, and CD40-CD40L interaction and NF-κB activation for the adjuvant effect.

Splenocytes from adult db/db and CD1d-knockout mice of both genders and their wild-type, C57BL/6 and Balb/C counterparts were examined for tumor necrosis factor (TNF)-alpha and TNF-alpha receptor type 1.
|
84 |
23527709
|
Despite the absence of inflammatory infiltrates, the hearts of db/db mice showed alterations in TNF-alpha receptor-1 and NFkB activity, including increased expression of both the NFkB p52 and p65 subunits.
|
85 |
23527709
|
In the hearts of CD1d-knockout mice, p52 expression was reduced, while p65 expression remained largely unchanged.
