|
29 |
7535058
|
Immunization with soluble protein antigens usually primers CD4+ T cells but not CD8+ T cells because of the stringent requirements for 'endogenous processing' for major histocompatibility complex (MHC) class I-restricted epitope presentation to CD8+ CTL.
|

|
We describe subcellular sites, alternative peptide transport mechanisms, and alternative modes of MHC class I molecule recycling that allow different modes of peptide loading of class I molecules.

|
37 |
9620217
|
To investigate the molecular and cellular mechanisms involved in the reduced tumorigenicity and increased immunogenicity of interleukin-2 (IL-2)-, IL-4- or IL-6-gene-transfected B16 melanoma vaccine, we have analyzed the functional and phenotypic properties of these genetically engineered melanoma cells in the present study.
|
38 |

|
Using fluorescence-activated cell sorting analysis, we found that both MHC class I and ICAM-1 expression were increased after IL-2, IL-4 or IL-6 gene transfection.
|
39 |
9620217
|
These results suggested that the decreased tumorigenicity of IL-2-, IL- 4-, and IL-6-gene-transfected B16 melanoma cells may be partly due to the increased sensitivity to effector cell cytotoxicity mediated by increased expression of ICAM-1 or MHC class I molecules on the tumor cell surface after cytokine gene transfection.

|
43 |
10928070
|
Our result implies that decreasing the amount of TGF-beta secreted from the autologous tumor vaccine by antisense strategy may significantly improve its immunogenicity through up-regulation of both MHC class I and Fas expressions.

The ability to monitor vaccine-elicited CD8(+) cytotoxic T-lymphocyte (CTL) responses in simian immunodeficiency virus (SIV)- and simian-human immunodeficiency virus (SHIV)-infected rhesus monkeys has been limited by our knowledge of viral epitopes predictably presented to those lymphocytes by common rhesus monkey MHC class I alleles.
|
53 |
11581386
|
We now define an SIV and SHIV Nef CTL epitope (YTSGPGIRY) that is presented to CD8(+) T lymphocytes by the common rhesus monkey MHC class I molecule Mamu-A*02.
|
54 |
11581386
|
All seven infected Mamu-A*02(+) monkeys evaluated demonstrated this response, and peptide-stimulated interferon gamma Elispot assays indicated that the response represents a large proportion of the entire CD8(+) T-lymphocyte SIV- or SHIV-specific immune response of these animals.

They can be repaired, at least partially and in vitro, by cytokines (IFNgamma, TNFalpha) or by DNA demethylation/histone hyperacetylation procedures.
|
81 |
15254748
|
The innate and adaptive antitumour immunity may be under some conditions interconnected: primary activation of the MHC class I-unrestricted surveillance mechanisms may lead to the production of IFNgamma by the activated NK/gammadelta T cells; the in situ produced IFNgamma may then up-regulate the MHC class I molecule expression on the tumour cell surface and in this way it may stimulate the more efficient, MHC class I-restricted, adaptive immunity.
|
82 |
15254748
|
Either therapeutic procedures aiming at up-regulation of MHC class I expression, or enhancement of MHC class I-unrestricted (CD4+, NK, NKT, gammadelta T) tumour defence effector mechanisms by dendritic cell-based therapeutic vaccines, by cytokines (IL-2, IL-12, IFNgamma, GM-CSF), or by the cytokine gene-based, genetically modified tumour vaccines should be considered.

We have developed a mass spectrometric approach which can be used to determine if an antigenic peptide is naturally processed and presented by any given MHC class I molecule.
|
84 |
15378283
|
The use of this technology negates the need to test peptides for their ability to stimulate CTL responses in those cases where the peptide is not naturally processed and bound to the target MHC class I molecule of interest, thus allowing resources to be focused on the most promising vaccine candidates.

Cutting edge: cross-presentation of cell-associated antigens to MHC class I molecule is regulated by a major transcription factor for heat shock proteins.
|
88 |
15528326
|
The ability for the professional APC to cross-present Ag to MHC class I from parenchymal cells is essential for priming as well as tolerance of CD8+ T cells against intracellular Ags.
|
89 |
15528326
|
We herein genetically addressed this hypothesis using mice that were defective of heat shock factor 1 (Hsf1), a major transcription factor for HSPs.
|
90 |
15528326
|
Hsf1(-/-) mice have a decreased expression of several HSPs including HSP90 and HSP70.
|
91 |
15528326
|
Using multiple Ag systems, we demonstrated that cross-priming of Ag-specific CD8+ T cells was inefficient when Ag expression was restricted to Hsf1(-/-) non-APCs.
|
92 |
15528326
|
Our study provides the first genetic evidence for the roles of Hsf1 in regulating cross-presentation of MHC class I-associated Ags.

This is accomplished by culturing virus-infected cells with stable isotope-labeled amino acids that are expected to be anchor residues (i.e. residues of the peptide that have amino acid side chains that bind into pockets lining the peptide-binding groove of the MHC class I molecule) for the human leukocyte antigen allele of interest.

We investigated all combinations of six classification methods (classification trees, artificial neural networks, support vector machines, as well as the more recently devised ensemble methods (bagging, random forests, boosting) with four peptide representation schemes (amino acid sequence, select biophysical properties, select quantitative structure-activity relationship (QSAR) descriptors, and the combination of the latter two) in predicting peptide binding to an MHC class I molecule (HLA-A2) and MHC class II molecule (HLA-DR4).

Here we identified an agonist variant of the SL9 peptide, p41 (SLYNTVAAL), by screening a large synthetic combinatorial nonapeptide library with ex vivo-primed SL9-specific T cells. p41 invariably immunized SL9-cross-reactive CTLs from other donors ex vivo and H-2Db beta2m double knockout mice expressing a chimeric HLA-A*0201/H2-Db MHC class I molecule.

To evaluate the role of the MHC class I molecule alpha3 domain in the activation of CD8(+) CTL, we have produced a soluble 227 mutant of H-2D(d), with a point mutation in the alpha3 domain (Glu227 --> Lys). 227 mutant class I-peptide complexes were not able to effectively activate H-2D(d)-restricted CD8 T cells in vitro, as measured by IFN-gamma production by an epitope-specific CD8(+) CTL line.
|
98 |
17981793

However, the 227 mutant class I-peptide complexes in the presence of another MHC class I molecule (H-2K(b)) (that cannot present the peptide) with a normal alpha3 domain can induce the activation of CD8(+) CTL.

|
108 |

We have recently shown that effective cytokine gene therapy of solid tumors in HLA-A2 transgenic (HHD) mice lacking murine MHC class I molecule expression results in the generation of HLA-A2-restricted CD8(+) T effector cells selectively recognizing tumor blood vessel-associated pericytes and/or vascular endothelial cells.
|

|
In the HHD model, effective vaccination resulted in profound infiltration of tumor lesions by CD8(+) (but not CD4(+)) T cells, in a coordinate reduction of CD31(+) blood vessels in the tumor microenvironment, and in the "spreading" of CD8(+) T cell responses to alternate TBVA that were not intrinsic to the vaccine.
|

|
Strikingly, the depletion of CD8(+), but not CD4(+), T cells at late time points after effective therapy frequently resulted in the recurrence of disease at the site of the regressed primary lesion.

Mucosa-associated invariant T (MAIT) cells are "innate" T cells that express an invariant T-cell receptor α-chain restricted by the nonclassical MHC class I molecule MHC-related protein 1 (MR1).

Mechanistic studies showed that MAIT cells required both MR1 and IL-12 40 kDa subunit (IL-12p40) signals from infected antigen presenting cells to control F. tularensis LVS intracellular growth.
|

|
Importantly, pulmonary F. tularensis LVS infection of MR1-deficient (MR1(-/-)) mice, which lack MAIT cells, revealed defects in early mucosal cytokine production, timely recruitment of IFN-γ-producing CD4(+) and CD8(+) T cells to the infected lungs, and control of pulmonary F. tularensis LVS growth.

The NK receptor, CD161, highly expressed by MAIT cells, modulated the cytokine but not the cytotoxic response triggered by bacteria infected cells.

After subcutaneous injection of fluorescein 5-isothiocyanate (FITC)-labeled NPs or FITC-ovalbumin (OVA)-carrying NPs (FITC-OVA-NPs), DCs migrated from the skin to the LNs and maturated, resulting in the upregulation of the costimulatory molecules CD80 and CD86 and the chemokine receptor CCR7.
|
135 |
24600553
|
FITC-OVA-NPs were found to be taken up by skin-derived CD103(+) DCs, and the processed antigen peptides were cross-presented by the major histocompatibility complex (MHC) class I molecule of DCs.

Unique to this animal was the presence of killing-competent CD8 T-cells, specific for NS3 1258-1272, being presented by the chimpanzee MHC class I molecule Patr-A*03∶01, and a high affinity recognition of this epitope.
