|
These results indicate that the peptide substituted for CLIP of Ii p33 bound to the groove of DR molecules in the same manner as CLIP and it was preferentially presented to the CD4+ T cell clone in the absence of HLA-DM molecules.

Melan-A/MART-1(51-73) represents an immunogenic HLA-DR4-restricted epitope recognized by melanoma-reactive CD4(+) T cells.
|
11 |
10618430
|
The human Melan-A/MART-1 gene encodes an HLA-A2-restricted peptide epitope recognized by melanoma-reactive CD8(+) cytotoxic T lymphocytes.
|
12 |
10618430
|
The Melan-A/MART-1(51-73) peptide was able to induce the in vitro expansion of specific CD4(+) T cells derived from normal DR4(+) donors or from DR4(+) patients with melanoma when pulsed onto autologous dendritic cells.
|
13 |
10618430
|
CD4(+) responder T cells specifically produced IFN-gamma in response to, and also lysed, T2.DR4 cells pulsed with the Melan-A/MART-1(51-73) peptide and DR4(+) melanoma target cells naturally expressing the Melan-A/MART-1 gene product.
|
14 |
10618430
|
Interestingly, CD4(+) T cell immunoreactivity against the Melan-A/MART-1(51-73) peptide typically coexisted with a high frequency of anti-Melan-A/MART-1(27-35) reactive CD8(+) T cells in freshly isolated blood harvested from HLA-A2(+)/DR4(+) patients with melanoma.
|
15 |
10618430
|
Taken together, these data support the use of this Melan-A/MART-1 DR4-restricted melanoma epitope in future immunotherapeutic trials designed to generate, augment, and quantitate specific CD4(+) T cell responses against melanoma in vivo.

|
Here, we report that (auto)antigen-specific human T cells are not killed in vitro by soluble TNF-related apoptosis-inducing ligand (TRAIL) although expressing death-inducing receptors, TRAIL receptor 1 (TRAIL-R1) and TRAIL-R2.
|
18 |
10889508
|
The (auto)antigen-specific T cells were also resistant to specific TRAIL-R1/TRAIL-R2-directed induction of apoptosis, indicating that coexpression of the truncated TRAIL-R3 and TRAIL-R4 in these T cells is not responsible for the observed resistance.
|
19 |

|
In contrast to CD95, the role of TRAIL receptors in MS might not involve regulation of T cell vulnerability.

Mouse monoclonal antibodies (mAb) with kappaL chains were targeted to various chemokine receptors expressed on human monocytes or immature dendritic cells (DC), and proliferation of cloned human, DR4-restricted CD4+ T cells specific for mouse Ckappa(40-48) was measured.
|
25 |
14579278
|
When using monocytes as antigen-presenting cells, mAb specific for CCR1, CCR2, CCR5, and CXCR4 were 100-10,000-fold more efficient at inducing T cell proliferation when compared to isotype-matched control mAb on a per molecule basis.

We therefore sought to identify promiscuous Th epitopes in hTERT, which can be presented by more than one MHC class II allele.
|
27 |
14581345
|
Each of 10 peptides derived from hTERT that were predicted to bind to MHC class II molecules was found to be able to induce primary human T-cell responses in vitro.
|
28 |
14581345
|
We then established CD4(+) T-cell clones specific for these peptides and found that only hTERT(766) (LTDLQPYMRQFVAHL)-specific CD4(+) Th cells were effective in recognizing naturally processed hTERT antigen.
|
29 |
14581345
|
We further found that the naturally processed epitopes hTERT(766) and hTERT(672) (which was identified previously) were promiscuous and capable of inducing CD4(+) T-cell responses in the context of several commonly found HLA-DR alleles, including DR1, DR7, and DR15 for hTERT(672), and DR4, DR11, and DR15 for hTERT(766).

In this pilot study, we show that immunization of three resected, high-risk metastatic melanoma patients with a T-helper epitope derived from the melanoma differentiation antigen, melanoma antigen recognized by T cells-1, results in CD4(+) T-cell immune responses.
|
32 |
15297401
|
Immune reactivity to that epitope was detected by DR4-peptide tetramer staining, and enzyme-linked immunospot assay of fresh and restimulated CD4(+) T cells from patients over the course of the 12-month vaccine regimen.

A variety of new monoclonal antibody (MoAb) agents, such as humanized anti-CD20, alemtuzumab, anti-HLA-DR, anti-CD22 (as an immunotoxin carrier), anti-CD40, as well as MoAb-targeting TRAIL-R1 and TRAIL-R2 are being tested.
|
46 |

18676860
|
These clones exerted a T helper 2 cytokine profile, had a CD4(+)CD25(+)Foxp3(+)GITR(+)CD127(-) T(reg) phenotype, and significantly inhibited the proliferative activity of allogeneic T cells independently of cell contact.
|
51 |
18676860
|
Furthermore, priming of T cells with the WT1-126 HLA-A0201-restricted peptide in the presence of T(regs) strongly inhibited the induction of anti-WT1-126 CD8(+) CTL responses as evidenced by both very low cytotoxic activity and IFN-gamma production.
|
52 |
18676860
|
Moreover, these T(reg) clones specifically produced granzyme B and selectively induced apoptosis in WT1-84-pulsed autologous antigen-presenting cells but not in apoptotic-resistant DR4-matched leukemic cells.

Escape of HIV-1-infected dendritic cells from TRAIL-mediated NK cell cytotoxicity during NK-DC cross-talk--a pivotal role of HMGB1.
|
55 |
20419158
|
We first addressed the question of the mechanisms involved in iDC editing, and we show that cognate NK-iDC interaction triggers apoptosis via the TNF-related apoptosis-inducing ligand (TRAIL)-Death Receptor 4 (DR4) pathway and not via the perforin pathway.
|
56 |
20419158
|
This resistance occurs despite normal amounts of TRAIL released by NK cells and comparable DR4 expression on DC(HIV).
|
57 |
20419158
|
High-mobility group box 1 (HMGB1), an alarmin and a key mediator of NK-DC cross-talk, was found to play a pivotal role in NK-dependent upregulation of c-FLIP and c-IAP2 in DC(HIV).
|
58 |
20419158
|
Finally, we demonstrate that restoration of DC(HIV) susceptibility to NK-induced TRAIL killing can be obtained either by silencing c-FLIP and c-IAP2 by specific siRNA, or by inhibiting HMGB1 with blocking antibodies or glycyrrhizin, arguing for a key role of HMGB1 in TRAIL resistance and DC(HIV) survival.

MHC II lung cancer vaccines prime and boost tumor-specific CD4+ T cells that cross-react with multiple histologic subtypes of nonsmall cell lung cancer cells.
|
65 |
20473949
|
Our vaccine strategy has focused on activating tumor-specific CD4(+) T cells, a population of lymphocytes that facilitates the optimal activation of effector and memory cytotoxic CD8(+) T cells.
|
66 |
20473949
|
We now report that our NSCLC MHC II vaccines prepared from adeno, squamous or large cell carcinomas each activate CD4(+) T cells that cross-react with the other NSCLC subtypes and do not react with HLA-DR-matched normal lung fibroblasts or other HLA-DR-matched nonlung tumor cells.
|
67 |
20473949
|
Using MHC II NSCLC vaccines expressing the DR1, DR4, DR7 or DR15 alleles, we also demonstrate that antigens shared among the different subtypes are presented by multiple HLA-DR alleles.
|
68 |
20473949
|
Therefore, MHC II NSCLC vaccines expressing a single HLA-DR allele activate NSCLC-specific CD4(+) T cells that react with the 3 major classes of NSCLC, and the antigens recognized by the activated T cells are presented by several common HLA-DR alleles, suggesting that the MHC II NSCLC vaccines are potential immunotherapeutics for a range of NSCLC patients.

Infection of BMDMs and primary lung fibroblasts with C. trachomatis strain L2, or the murine pathogen C. muridarum, led to higher levels of MIP2 mRNA expression or IL-1β secretion from TRAIL-R-deficient cells than WT cells.
|
83 |
24695582
|
Similarly, depletion of TRAIL-R1 expression in human epithelial cells resulted in a higher level of IL-8 mRNA expression and protein secretion during C. trachomatis infection.

In vitro analysis revealed a higher resistance to bortezomib possibly due to an altered gene expression profile caused by del(8)(p21) including genes such as TRAIL-R4, CCDC25, RHOBTB2, PTK2B, SCARA3, MYC, BCL2 and TP53.
|
85 |
26378933
|
Furthermore, while bortezomib sensitized MM cells without del(8)(p21) to TRAIL/APO2L mediated apoptosis, in cells with del(8)(p21) bortezomib failed to upregulate the pro-apoptotic death receptors TRAIL-R1 and TRAIL-R2 which are located on the 8p21 region.
