80 15254748 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.
83 15378283 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.

87 15528326 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.
93 15993518 We demonstrate that a recombinant MVSchw virus expressing an HIV-1-derived CTL polyepitope primes effective HLA-A0201-restricted CTLs against multiple conserved HIV-1 epitopes in mice susceptible to measles and humanized for the major histocompatibility complex (MHC) class-I molecule HLA-A0201.
94 16432254 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.
95 16646843 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).
96 16709828 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.
97 17981793 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.
99 17981793 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.
100 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.

106 18406420 To study the MHC class I antigen-processing pathway, the protein antigen of interest has to be expressed inside the cells.
107 18406420 Mouse fibroblast and RMA cells were able to properly process OVA protein, and OVA-derived peptide OVA(258-265) (or SIINFEKL) was successfully presented via the MHC class I molecule (K(b)) to SIINFEKL-K(b)-specific T cell hybridoma B3Z.
108 18406420 As expected, delivery of OVA protein into RMA-S, a cell line with a deficiency in MHC class I antigen processing due to a TAP defect, failed to present the SIINFEKL epitope to B3Z.
109 18491093 One type of metastases characterized by upregulation of all MHC class I antigens and another type with partial IFN-gamma resistance, namely with lack of expression of L(d)-MHC class I molecule.
110 18726439 After DNA transfection, the epitope minigenes were expressed respectively in two human cell lines, each bearing one MHC class I molecule named CIR/HLA-A2.1 and K562/HLA-B51.
111 19238199 Here we used inverse folding approach to study the peptide specificity of MHC Class-I molecule with the aim of obtaining a better differentiation between binding and nonbinding sequence.
112 20212098 A DNA plasmid was constructed encoding an SCT incorporating the human MHC class I molecule HLA-A2 and the immunodominant peptide SVG9 derived from the envelope protein of West Nile virus (WNV).
113 20212098 Inclusion of a CD4(+) Th cell epitope within the SCT did not increase the frequency of SVG9-specific CD8(+) T cells, but did enhance protection against WNV challenge.

119 22084443 Structural basis of diverse peptide accommodation by the rhesus macaque MHC class I molecule Mamu-B*17: insights into immune protection from simian immunodeficiency virus.
120 22084443 The MHC class I molecule Mamu-B*17 has been associated with elite control of SIV infection in rhesus macaques, akin to the protective effects described for HLA-B*57 in HIV-infected individuals.
121 22084443 In this study, we determined the crystal structures of Mamu-B*17 in complex with eight different peptides corresponding to immunodominant SIV(mac)239-derived CD8(+) T cell epitopes: HW8 (HLEVQGYW), GW10 (GSHLEVQGYW), MW9 (MHPAQTSQW), QW9 (QTSQWDDPW), FW9 (FQWMGYELW), MF8 (MRHVLEPF), IW9 (IRYPKTFGW), and IW11 (IRYPKTFGWLW).

125 22121944 CD8 T lymphocytes recognise the steric configuration of functional groups at the TCR contact side chain with a parallel observation that peptide backbones of various epitopes adapt to the conserved conformation upon binding to the same MHC class I molecule.
126 22246626 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.
127 22246626 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.
128 22246626 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.
129 23898209 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).
130 23898209 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.
131 23898209 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.
132 24130485 This recognition depends on the detection of microbial compounds presented by the evolutionarily conserved major-histocompatibility-complex (MHC) class I molecule, MR1.
133 24130485 The NK receptor, CD161, highly expressed by MAIT cells, modulated the cytokine but not the cytotoxic response triggered by bacteria infected cells.
134 24600553 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.
136 24740375 In the animal that cleared infection, NS3-specific CD8 T-cell responses were observed to be more potent in terms of frequency and polyfunctionality of cytokine producing cells.
137 24740375 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.
138 24915083 In order to clarify the structural characteristics of the bovine MHC class I molecule (BoLA-I) complexed with CD8αα (CD8αα-BoLA-I), bovine CD8αα, BoLA-I (BoLA-2*02201) and β2m were expressed and purified, and were then assembled with a peptide derived from Foot-and-mouth disease virus (FMDV-VP1YY9) and crystallized.
139 25457547 The swine major histocompatibility complex (MHC) genomic region (SLA) is extremely polymorphic comprising high numbers of different alleles, many encoding a distinct MHC class I molecule, which binds and presents endogenous peptides to circulating T cells of the immune system.
140 26020813 Because HLA-B is the most polymorphic human MHC class I molecule and correlates strongly with HIV-1 progression, we determined sequences for its ortholog, Patr-B, in 125 Gombe chimpanzees.
141 26148331 We observed that at d 3-4 post vaccination, 6 genes were down-regulated, namely APC, CD3G, FASLG, IL7, CD8A and TLR1.
142 26148331 Meanwhile at 6-7 days post vaccination, 9 genes were significantly up-regulated, including RIPK2, TGFB1, MICB, SOCS1, IL2RA, MS4A1, PTPRC, IL2 and IL8.
143 26148331 By days 12-15 the genes RIPK2, IL4, IL12B and TLR2 were overexpressed.
