10866317
|
Both granulocyte-macrophage colony-stimulating factor (GM-CSF) and flt3-ligand (FL) induce the development of dendritic cells (DCs).
|
5 |
10866317
|
DCs generated by GM-CSF were CD8alpha- and expressed higher levels of B7-1 and CD1d than DCs cells generated by FL.

However, CD1a, b, and c (group 1 CD1 molecules) are not present at significant levels on circulating monocytes unless their expression is induced by cytokines such as granulocyte-macrophage colony-stimulating factor (GM-CSF).
|
7 |
10941828
|
In vitro, antigen-triggered expression of these molecules was mediated by GM-CSF, since neutralization of this cytokine with specific antibody totally abrogated CD1a, b, and c expression.
|

10941828
|
In contrast to the group 1 CD1 molecules, CD1d was found to be constitutively expressed on the majority of circulating monocytes and B lymphocytes prior to immunization.
|

|
There was no effect of antigenic stimulation with tetanus toxoid on the cell surface expression of CD1d, suggesting major differences in regulation of the expression and function of the different CD1 molecules in humans.

|
Altogether our results point to antigen-driven up-regulation of CD1a, b, and c expression on human monocytes that is mediated by GM-CSF and no effect on CD1d expression.

|
When bone marrow-derived dendritic cells (DC) were infected with BCG, the expression of MHC class I molecules by DC was up-regulated in parallel with MHC class II and B7-2, whereas CD1d expression level was not modified.
|
23 |
11282984
|
Moreover, BCG-infected DC activated MPT64(190-198)-specific CD8(+) T cells to secrete IFN-gamma, although with a lower efficacy than VVWR-64-infected DC.

Activation of natural killer T (NKT) cells by the glycolipid ligand, alpha-galactosylceramide (alpha-GalCer), causes bystander activation of NK, B, CD4(+), and CD8(+) T cells.
|

In multiple murine models, granulocyte-macrophage colony stimulating factor (GM-CSF) proved to be the most potent immunostimulatory product.
|
41 |
12445288
|
Vaccination with irradiated tumor cells engineered to secrete GM-CSF involves enhanced tumor antigen presentation by recruited dendritic cells (DCs) and macrophages; the coordinated functions of CD4+ and CD8+ T cells, CD1d-restricted NKT cells and antibodies mediate protective immunity.

CD1d-restricted T cells regulate dendritic cell function and antitumor immunity in a granulocyte-macrophage colony-stimulating factor-dependent fashion.
|
45 |
12847287
|
Here we show that tumor cells engineered to secrete granulocyte-macrophage colony-stimulating factor induce the expansion of CD1d-restricted T cells through a mechanism that involves CD1d and macrophage inflammatory protein 2 expression by CD8 alpha-, CD11c+ dendritic cells (DCs).

Observing high frequencies of CD4 and CD8 coreceptor expression in human CD56+ T cells, we examined the potential role of major histocompatibility complex (MHC) class II molecules in the activation of these cells.
|
55 |
14607868
|
Activation of mononuclear cells with bacterial superantigens presented by MHC class II molecules resulted in increased frequency of CD56+ T cells.
|
56 |
14607868
|
Primarily, CD4+ cells within the CD56+-T-cell population responded to the bacterial superantigens, and cytokine expression profiles were Th1-like.
|
57 |
14607868
|
Collectively, our data suggest that a significant number of CD56+ T cells recognize pathogen-associated ligands in association with MHC class II molecules.

Transforming growth factor-beta production and myeloid cells are an effector mechanism through which CD1d-restricted T cells block cytotoxic T lymphocyte-mediated tumor immunosurveillance: abrogation prevents tumor recurrence.
|
59 |
14657224
|
Our previous work demonstrated that cytotoxic T lymphocyte (CTL)-mediated tumor immunosurveillance of the 15-12RM tumor could be suppressed by a CD1d-restricted lymphocyte, most likely a natural killer (NK) T cell, which produces interleukin (IL)-13.
|
60 |
14657224
|
T cell-reconstituted recombination activating gene (RAG)2 knockout (KO) and RAG2/IL-4 receptor alpha double KO mice showed that inhibition of immunosurveillance requires IL-13 responsiveness by a non-T non-B cell.
|
61 |
14657224
|
Such nonlymphoid splenocytes from tumor-bearing mice produced more transforming growth factor (TGF)-beta, a potent inhibitor of CTL, ex vivo than such cells from naive mice, and this TGF-beta production was dependent on the presence in vivo of both IL-13 and CD1d-restricted T cells.
|
62 |
14657224
|
Further, blocking TGF-beta or depleting Gr-1+ cells in vivo prevented the tumor recurrence, implying that TGF-beta made by a CD11b+ Gr-1+ myeloid cell, in an IL-13 and CD1d-restricted T cell-dependent mechanism, is necessary for down-regulation of tumor immunosurveillance.
|
63 |
14657224
|
Identification of this stepwise regulation of immunosurveillance, involving CD1-restricted T cells, IL-13, myeloid cells, and TGF-beta, explains previous observations on myeloid suppressor cells or TGF-beta and provides insights for targeted approaches for cancer immunotherapy, including synergistic blockade of TGF-beta and IL-13.

HCs upregulate surface expression of major histocompatibility complex (MHC) class I molecules and CD1d but not MHC class II molecules Qa-1, CD80, CD86, CD54, or CD95; in addition, they expressed/secreted interleukin (IL)-10 and IL-4 but not IL-1, IL-6, IL-13, interferon (IFN)-gamma, tumor necrosis factor (TNF), IL-4, or IL-27 (i.e., they acquire the HC* phenotype).

HCs* (but not HCs) induced specific activation, proliferation, and IFN-gamma, TNF, and IL-13 release of cocultured naïve CD8(+) T cells.
|
84 |
15122754
|
Only recently activated CD8(+) T blasts (but not recently activated CD4(+) T blasts or activated cells of the innate immune system, including natural killer T [NKT] cells) induced the HC* phenotype that is prominent from day 10 to day 20 postvaccination (i.e., time points at which peak numbers of recently primed CD8(+) T blasts are found in the liver).

Activation of invariant CD1d-dependent NK T cells (iNKT cells) in vivo through administration of the glycolipid ligand alpha-galactosylceramide (alpha-GalCer) or the sphingosine-truncated alpha-GalCer analog OCH leads to CD40 signaling as well as the release of soluble molecules including type 1 and gamma interferons that contribute to DC maturation.
|
86 |
15599405

The adjuvant activity of alpha-GalCer enhances both priming and boosting of CD8(+) T cells to coadministered peptide or protein antigens, including a peptide encoding the clinically relevant, HLA-A2-restricted epitope of the human tumor antigen NY-ESO-1.

We also asked the role of interleukin (IL)-4 receptor alpha (IL-4Ralpha)-signal transducer and activator of transcription 6 (STAT6) signaling, including IL-13, and transforming growth factor beta (TGF-beta) by using gene-disrupted mice or treating mice with cytokine antagonists.

Despite recent gains in knowledge regarding CD1d-restricted NKT cells, very little is understood of non-CD1d-restricted NKT cells such as CD8(+)NK1.1(+) T cells, in part because of the very small proportion of these cells in the periphery.
|
110 |
18490727
|
In this study we took advantage of the high number of CD8(+)NK1.1(+) T cells in IL-15-transgenic mice to characterize this T cell population.
|
111 |
18490727
|
In the IL-15-transgenic mice, the absolute number of CD1d-tetramer(+) NKT cells did not increase, although IL-15 has been shown to play a critical role in the development and expansion of these cells.
|
112 |
18490727

The CD8(+)NK1.1(+) T cells in the IL-15-transgenic mice did not react with CD1d-tetramer.

113 |
18490727
|
In contrast to CD4(+)NK1.1(+) T cells, which were mostly CD1d-restricted NKT cells and of which approximately 70% were CD69(+)CD44(+), approximately 70% of CD8(+)NK1.1(+) T cells were CD69(-)CD44(+).

These results suggest that high levels of IL-15 induce expansion or differentiation of a novel NK1.1(+) T cell subset, CD8alphaalphaNK1.1(+) T cells, and that IL-15-transgenic mice may be a useful resource for studying the functional relevance of CD8(+)NK1.1(+) T cells.

In vitro cell proliferation studies in the presence of GPI-attached PA63 peptides revealed that there was a clonal expansion of CD4(+) NK1.1(+) helper T cell population which rapidly produced IL-4 in response to T cell receptor ligation.
|
146 |
19195490
|
In addition, the group pTPA.GPI-PA63 also displayed low magnitude MHC-II restricted (CD1d-independent) NKT cell and CD4(+) T cell helper responses in response to non-GPI attached PA63 peptides which overall resulted in the heightened responses seen for this group.

149 |
19620295
|
Treatment with neutralizing Ab to CD1d reduces the OVA-specific Ab response only in MyD88-sufficient wild-type mice, suggesting that both Ag-specific CD4 T cell and invariant NKT cell effector responses to Salmonella-OVA vaccination are MyD88 dependent.

Group 1 CD1 (CD1a, CD1b, and CD1c)-restricted T cells recognize mycobacterial lipid antigens and are found at higher frequencies in Mycobacterium tuberculosis (Mtb)-infected individuals.
|
152 |
19808251
|
In contrast to CD1d-restricted NKT cells, which rapidly respond to initial stimulation but exhibit anergy upon reexposure, group 1 CD1-restricted T cells exhibit delayed primary responses and more rapid secondary responses, similar to conventional T cells.

We also found that a ligand for CD1d-reactive natural killer T (NKT) cells, alpha-glucuronosylceramide (GSL1), enhanced MvP728-induced interleukin-12 production in human dendritic cells and that in vivo coadministration of a NKT ligand with MvP728-Llo or MvP728-survivin enhanced effector-memory cytotoxic T lymphocyte (CTL) responses.

155 |
19830696
|
Though TGF-beta inhibition enhances antitumor immunity mediated by CD8(+) T cells in several tumor models, it is not always sufficient for rejection of tumors.
|
156 |
19830696
|
Though the abrogation of CD1d-restricted NKT cells, which have been reported to induce TGF-beta production by MDSC through an IL-13-IL-4R-STAT6 pathway, partially enhanced antitumor immunity regardless of vaccination, abrogation of the NKT cell-IL-13-IL-4R-STAT-6 immunoregulatory pathway did not enhance vaccine efficacy.
|
157 |
19830696
|
Taken together, these data indicated that anti-TGF-beta enhances efficacy of a prophylactic vaccine in normal individuals despite their not having the elevated TGF-beta levels found in patients with cancer and that the effect is not dependent on TGF-beta solely from CD4(+)CD25(+) T regulatory cells or the NKT cell-IL-13-IL-4R-STAT-6 immunoregulatory pathway.

177 |
26174952
|
The protein up-regulated TLR2 and TLR6 and stimulated the activation and costimulatory molecules on FO B cells skewing the cells toward TLR-dependent type-1 cytokine response.
|
178 |
26174952
|
These cells responded to porin by expressing toll-interacting protein (TOLLIP), the TLR2 and -4 signaling inhibitor along with stimulation of the intracellular pathogen recognition receptor NLR caspase recruitment domain containing protein 5 (NLRC5).

However, expression of CD1d on moDC has been shown to be negatively correlated with expression of CD1a, which in turn has been suggested to be a surrogate marker for IL-12 secreting type-1 polarized moDC, the preferred functional characteristics for cancer vaccines.
|
182 |
26460687
|
Here we challenge this notion by showing that plasma-derived lipids drive functional levels of CD1d expression, while CD1a expression can vary considerably in these cells without being correlated with a loss of polarization or immunogenicity.
