Depletion of CD8+ T cells eliminated or markedly reduced the CTL activity, while depletion of CD4+ T cells did not affect CTL responses.
|

7561107
|
CTL activity was blocked by mAbs to human class I MHC Ags, but not by mAbs to class II MHC Ags.

|
In addition, CT also elicited adjuvant effects for Ag-specific IgG1, IgE, and IgA responses when two other protein Ags, OVA and hen egg white lysozyme, were given by the oral route.

|
Both Peyer's patches and splenic CD4+ T cells expressed markedly increased levels of IL-4-specific message, but did not result in changes in IFN-gamma mRNA expression.

|
Because the env protein associates tightly with CD4 shortly after synthesis, we first targeted the env protein using a chimeric CD4 protein consisting of the extracellular domain of CD4 and the transmembrane and cytoplasmic domains of LAMP-1.

Development and characterization of recombinant adenoviruses encoding MART1 or gp100 for cancer therapy.
|
9 |
8543823
|
The human melanoma tumor Ags, MART1 and gp100, are specifically recognized by HLA-A2-restricted CD8+ CTLs derived from melanoma patients and appear to be involved in tumor regression.
|
10 |
8543823
|
Infection of non-Ag expressing HLA-A2+ cell lines A375 and MDA-231 with the vectors resulted in recognition by Ag-specific CTLs as demonstrated by specific target cell lysis and release of cytokines, including IFN-gamma, TNF-alpha, and granulocyte-macrophage-CSF.
|
11 |
8543823
|
Because of the suspected homology between the human MART1 and gp100 genes and their murine counterparts, we immunized C57BL/6 mice with these recombinant adenoviruses and demonstrated that immunization with Ad2CMV-gp100 could protect mice from murine melanoma B16 challenge administered intradermally.
|
12 |
8543823
|
Depletion of CD8+ but not CD4+ T cells in vivo from Ad2CMV-gp100-vaccinated mice eliminated the protective effect.
|

|
The approach uses autologous tumor cells genetically modified to express syngeneic MHC class II genes as cell-based immunogens and is based on the hypothesis that tumor cells directly present tumor Ags to CD4+ T cells.

|
Recognition of an antigenic peptide derived from tyrosinase-related protein-2 by CTL in the context of HLA-A31 and -A33.
|
15 |
9551926
|
Two T cell epitopes derived from tumor Ags, tyrosinase-related protein (TRP)-1 and TRP-2, were shown to be recognized by HLA-A31 restricted TIL586 and its T cell clones.
|
16 |
9551926
|
It was found that both peptides were capable of binding to HLA-A3, -A11, -A31, -A33, and -A68 of the HLA-A3 supertype.

HLA-independent heterogeneity of CD8+ T cell responses to MAGE-3, Melan-A/MART-1, gp100, tyrosinase, MC1R, and TRP-2 in vaccine-treated melanoma patients.
|
18 |
9862732
|
To identify such peptides, we evaluated HLA-A*02+ melanoma patients immunized to a polyvalent vaccine containing multiple Ags, including MAGE-3, Melan-A/MART-1, gp100, tyrosinase, melanocortin receptor (MC1R), and dopachrome tautomerase (TRP-2).
|
19 |
9862732
|
Using a filter spot assay, we measured peripheral blood CD8+ T cell responses, before and after immunization, to a panel of 45 HLA-A*0201-restricted peptides derived from these Ags.
|
20 |
9862734
|
Although cDNAs encoding the previously identified melanoma Ags, tyrosinase and gp100, were isolated, these TIL were found to recognize previously unidentified peptides.
|

|
Although the mechanism of adjuvanticity of CT is not completely understood, it is known that CT induces mucosal epithelial cells to produce the proinflammatory cytokines IL-1, IL-6, and IL-8 and up-regulates macrophage production of IL-1 and the costimulatory molecule B7.2.
|
22 |
10229857
|
Because IL-1 may duplicate many of the activities of CT, we evaluated IL-1alpha and IL-1beta for their ability to serve as mucosal adjuvants when intranasally administered with soluble protein Ags.
|
23 |
10229857
|
IL-1alpha and IL-1beta were as effective as CT for the induction of Ag-specific serum IgG, vaginal IgG and IgA, systemic delayed-type hypersensitivity, and lymphocyte proliferative responses when intranasally administered with soluble protein Ag.
|

CD40 ligand (CD154) enhances the Th1 and antibody responses to respiratory syncytial virus in the BALB/c mouse.
|
26 |
10820273
|
CD40 ligand (CD40L) is a cell surface costimulatory molecule expressed mainly by activated T cells.
|
27 |
10820273
|
CD40L expression promotes Th1 cytokine responses to protein Ags and is responsible for Ig isotype switching in B cells.
|
28 |
10820273
|
These studies show that coincident expression of CD40L enhances the Th1 (IL-2 and IFN-gamma) cytokine responses, increases the expression of TNF-alpha and NO, accelerates virus clearance, and increases the anti-F and anti-G Ab responses.
|
29 |

Oral delivery of a large dose or prolonged feeding of protein Ags induce systemic unresponsiveness most often characterized as reduced IgG and IgE Ab- and Ag-specific CD4(+) T cell responses.

Targeting antigen in mature dendritic cells for simultaneous stimulation of CD4+ and CD8+ T cells.
|
31 |
11290810
|
Immature DC (DCimm) capture, process, and present Ags to CD4(+) lymphocytes, which reciprocally activate DCimm through CD40, and the resulting mature DC (DCmat) loose phagocytic capacity, but acquire the ability to efficiently stimulate CD8(+) lymphocytes.
|
32 |
11290810
|
Recombinant vaccinia viruses (rVV) provide a rapid, easy, and efficient method to introduce Ags into DC, but we observed that rVV infection of DCimm results in blockade of DC maturation in response to all activation signals, including CD40L, monocyte-conditioned medium, LPS, TNF-alpha, and poly(I:C), and failure to induce a CD8(+) response.
|
33 |
11290810
|
These results demonstrate that despite rVV interference with DCimm maturation, a single targeting vector can deliver Ags to DCmat for the effective simultaneous stimulation of both CD4(+) and CD8(+) cells.

HIV envelope protein inhibits MHC class I presentation of a cytomegalovirus protective epitope.
|
39 |

|
CTL recognize peptides that derive from viral protein Ags by proteolytic processing and are presented by MHC class I molecules.
|
40 |
11591745
|
Also, point mutants of the presenting MHC class I molecule differed in their competition pattern.
|
41 |
11591745
|
We conclude that, although not the rule, in certain combinations there is interference between different Ags expressed in the same cell and presented by the same MHC class I allele.

Multiple Chlamydia pneumoniae antigens prime CD8+ Tc1 responses that inhibit intracellular growth of this vacuolar pathogen.
|
47 |
12193722
|
Eighteen H-2(b) binding peptides representing sequences from 12 Cpn Ags sensitized target cells for MHC class I-restricted lysis by CD8(+) CTL generated from the spleens and lungs of infected mice.
|
48 |
12193722
|
Peptide-specific IFN-gamma-secreting CD8(+) T cells were present in local and systemic compartments after primary infection, and these cells expanded after pathogen re-exposure.
|
49 |
12193722
|
CD8(+) T cell lines to the 18 Cpn epitope-bearing peptides were cytotoxic, displayed a memory phenotype, and secreted IFN-gamma and TNF-alpha, but not IL-4.
|
50 |
12193722
|
Finally, Cpn peptide-specific CD8(+) CTL suppressed chlamydial growth in vitro by direct lysis of infected cells and by secretion of IFN-gamma and other soluble factors.
|
51 |
12391186
|
Using monocyte-derived immature DCs and those stimulated with TNF-alpha for maturation, we observed that none of the CD1 isoforms underwent changes in intracellular trafficking that mimicked MHC class II molecules during DC maturation.
|
52 |
12391186
|
In contrast to the striking increase in surface expression of MHC class II on mature DCs, the surface expression of CD1 molecules was either increased only slightly (for CD1b and CD1c) or decreased (for CD1a).
|
53 |
12391186
|
Consistent with this, DCs efficiently presented CD1b-restricted lipid Ags to specific T cells similarly in immature and mature DCs.
|
54 |
12734382
|
DC-888mel hybrids efficiently presented HLA-A*0201-restricted epitopes from the melanoma Ags MART-1, gp100, tyrosinase, and tyrosinase-related protein 2 as evaluated by specific cytokine secretion from six distinct CTL lines.
|
55 |
12734382
|
In contrast, DCs could not cross-present MHC class I-restricted epitopes after exogenously loading with gp100 protein.
|
56 |
12734382
|
DC-888mel hybrids also presented HLA-DR beta 1*0401- and HLA-DR beta 1*0701-restricted peptides from gp100 to CD4(+) T cell populations.
|
57 |
12734382
|
Therefore, fusions of DCs and tumor cells express both MHC class I- and class II-restricted tumor-associated epitopes and may be useful for the induction of tumor-reactive CD8(+) and CD4(+) T cells in vitro and in human vaccination trials.

Presentation of exogenous whole inactivated simian immunodeficiency virus by mature dendritic cells induces CD4+ and CD8+ T-cell responses.
|
59 |

|
AT-2 SIV interacts authentically with T cells and DCs and thus allows assessment of natural SIV-specific responses.
|
60 |
14501788
|
CD4+ and CD8+ T cells from blood or lymph nodes of SIV-infected macaques released interferon-gamma (IFN gamma) and proliferated in response to a variety of AT-2 SIV isolates.
|
61 |
14501788
|
Presentation of Ags derived from AT-2 SIV by DCs was more potent than presentation by comparably Ag-loaded monocytes.
|
62 |
14501788
|
Interestingly, SIV-pulsed mature DCs stimulated both CD4+ and CD8+ T-cell responses, whereas immature DCs primarily stimulated CD4+ T cells.
|
63 |
14634146
|
We previously described HLA-B35-restricted melanoma tumor-infiltrating lymphocyte responses to frequently expressed melanoma-associated Ags: tyrosinase, Melan-A/MART-1, gp100, MAGE-A3/MAGE-A6, and NY-ESO-1.
|
64 |
14634146
|
In particular, the HLA-B35-restricted Melan-A epitope is mimicked by the peptide 26-35, already known as the most immunodominant melanoma epitope in the HLA-A*0201 context.
|
65 |
14688364
|
These data lead us to suggest that the central issue concerning the mechanisms underlying different functional outcomes for anti-bacterial IgG responses to capsular polysaccharide vs protein Ags is not necessarily based on the ability to recruit cognate CD4+ T cell help, but perhaps on the nature of the B cell Ag receptor signaling that occurs and/or on the responding B cell subpopulations.
|
66 |
15294974
|
We report the use of a novel pH-triggered microparticle that exploits the ability of APCs to cross-present MHC I-restricted Ags that have been engulfed in the low pH environment of the phagosome.
|
67 |
15294974
|
Encapsulation of MHC I epitopes in pH-triggered microparticles increases Ag presentation and may improve CD8(+) T cell priming to peptide vaccines against viruses and cancer.

Identification of a human HLA-E-restricted CD8+ T cell subset in volunteers immunized with Salmonella enterica serovar Typhi strain Ty21a typhoid vaccine.
|
69 |
15494539
|
Typhi-infected targets regardless of whether they share classical HLA class I molecules with them, by a FAS-independent, granule-dependent mechanism, as evidenced by induction of granzyme B release and the blocking effects of concanamycin and strontium ions.

Typhi GroEL HLA-E binding motifs.
|
73 |
15494539
|
These results demonstrate that HLA-E binds nonamer peptides derived from bacterial proteins and trigger CD8+-mediated lysis and IFN-gamma production when exposed to infected targets, raising the possibility that this novel effector mechanism might contribute to host defense against intracellular bacterial infections.

Indeed, a recent study revealed CTLs specific for two cancer-testis (CT) Ags (MAGE-A1 and MAGE-A3) in tumor infiltrating lymphocytes of HCC patients.
|
75 |
15661935
|
Here we assessed the presence of T cells specific for additional CT Ags: MAGE-A10, SSX-2, NY-ESO-1, and LAGE-1, which are naturally immunogenic as demonstrated in HLA-A2(+) melanoma patients.
|
76 |
15661935
|
Therefore, besides melanoma, HCC is the second solid human tumor with clear evidence for in vivo tumor recognition by T cells, providing the rational for specific immunotherapy, based on immunization with CT Ags such as MAGE-A10 and SSX-2.

MAGE-A1-, MAGE-A10-, and gp100-derived peptides are immunogenic when combined with granulocyte-macrophage colony-stimulating factor and montanide ISA-51 adjuvant and administered as part of a multipeptide vaccine for melanoma.
|
81 |
15728523
|
We report in this study that at least three of these five peptides (MAGE-A1(96-104), MAGE-A10(254-262), and gp100(614-622)) are immunogenic when administered with GM-CSF in Montanide ISA-51 adjuvant.
|
82 |
15728523
|
Most importantly, tumor cell lines expressing the appropriate HLA-A restriction element and MAGE-A1, MAGE-A10, or gp100 proteins were lysed by corresponding CTL.
|
83 |
15728523
|
This report supports the continued use of the MAGE-A1(96-104), MAGE-A10(254-262), and gp100(614-622) epitopes in peptide-based melanoma vaccines and thus expands the list of immunogenic peptide Ags available for human use.
|
84 |
15728523
|
Cancer-testis Ags are expressed in multiple types of cancer; thus the MAGE-A1(96-104) and MAGE-A10(254-262) peptides may be considered for inclusion in vaccines against cancers of other histologic types, in addition to melanoma.

Abs against glycolipids GM2, globo H and Lewis Y, protein KSA (epithelial cell adhesion molecule, also known as EpCAM) and mucin Ags Tn, sialylated Tn, Thomsen Friedenreich (TF), and MUC1 all reacted comparably by FACS with tumor cells expressing these Ags.
|
91 |
15843572
|
Compared with the strong complement binding and CDC with Abs against glycolipids and KSA, complement binding was diminished with Abs against mucin Ags and no CDC was detected.

In contrast, SAG1(c) mutants produced reduced brain cyst loads early in chronic infection, but these substantially increased over time accompanying a hyperproduction of IFN-gamma, TNF-alpha, and IL-10, and severe encephalitis.

We conclude that stage-specific expression of SRS Ags is among the key mechanisms by which optimal parasite persistency is established and maintained.

Recombinant Ags 85A, 85B, and 85C induced significant lymphocyte proliferation as well as the production of gamma interferon (IFN-gamma), interleukin-2 (IL-2), IL-12, and tumor necrosis factor alpha (TNF-alpha), but not IL-4, from low and medium shedders.
|
97 |
16041023
|
The 35-kDa protein also induced significant lymphocyte proliferation as well as the production of IFN-gamma and IL-4 from low and medium shedders.
|
98 |
16041023
|
CD4(+) T cells and CD25(+) (IL-2R) T cells were stimulated the most by 85A and 85B, while the 35-kDa protein primarily stimulated CD21(+) B cells involved in humoral immune responses.
|
99 |
16116238
|
Viral vectors may address both of these issues, as they can be used to deliver intact tumor Ags to DCs, and have been shown to inhibit the suppression mediated by CD4+CD25+ regulatory T cells.
|

16116238
|
VRP infection of immature DCs was superior to TNF-alpha treatment at inducing phenotypic maturation of DCs, and was comparable to LPS stimulation.
|
101 |
16116238
|
Additionally, VRP-infected DC cultures secreted substantial amounts of the proinflammatory cytokines IL-6, TNF-alpha, and IFN-alpha.
|
102 |
16116238
|
Finally, DCs transduced with a VRP encoding the influenza matrix protein (FMP) stimulated 50% greater expansion of FMP-specific CD8+ CTL when compared with TNF-alpha-matured DCs pulsed with an HLA-A*0201-restricted FMP peptide.

We have investigated how IFN-alphabeta induces cross-priming, comparing CD8+ T cell responses generated against soluble protein Ags in the presence or absence of IFN-alphabeta.
|
104 |
16585561
|
Injection of IFN-alpha was found to prolong the proliferation and expansion of Ag-specific CD8+ T cells, which was associated with marked up-regulation of IL-2 and IL-15 receptors on Ag-specific cells and expression of IL-15 in the draining lymph node.
|
105 |
16585561
|
Surprisingly, neither IL-2 nor IL-15 was required for IFN-alpha-induced cross-priming.

Efficient immunization and cross-priming by vaccine adjuvants containing TLR3 or TLR9 agonists complexed to cationic liposomes.
|
107 |
16751377
|
We found that liposomes complexed to nucleic acids (liposome-Ag-nucleic acid complexes; LANAC) were particularly effective adjuvants for eliciting CD4(+) and CD8(+) T cell responses against peptide and protein Ags.
|
108 |
16751377
|
Notably, LANAC containing TLR3 or TLR9 agonists effectively cross-primed CD8(+) T cell responses against even low doses of protein Ags, and this effect was independent of CD4(+) T cell help.

CD8+ T cell protective immunity against Chlamydia pneumoniae includes an H2-M3-restricted response that is largely CD4+ T cell-independent.
|
113 |
17785832
|
Recently, we reported that type 1 CD8+ (Tc1) from Cpn-infected B6 mice recognize peptides from multiple Cpn Ags in a classical MHC class Ia-restricted fashion.
|
114 |
17785832
|
H2-M3-binding peptides representing the N-terminal formylated sequences from five Cpn Ags sensitized target cells for lysis by cytolytic effectors from the spleens of infected B6 mice.
|
115 |
17785832
|
Of these, only peptides fMFFAPL (P1) and fMLYWFL (P4) stimulated IFN-gamma production by infection-primed splenic and pulmonary CD8+ T cells.
|
116 |
17785832
|
Finally, we show that in the absence of MHC class Ia-restricted CD8+ T cell responses, CD4+ T cells are largely expendable for the control of Cpn growth, and for the generation, memory maintenance, and secondary expansion of P1- and P4-specific CD8+ T cells.
|
117 |
18097032
|
This results in efficient expansion of Ag-specific CD8+ and CD4+ T cells and improved effector functions.
|
118 |
18097032
|
We used CMVpp65 and NY-ESO-1 Ags to study preformed immune responses in CMV-seropositive individuals and cancer patients.
|
119 |
18097032
|
We show that linking these Ags to the MITD trafficking signal allows simultaneous, polyepitopic expansion of CD8+ and CD4+ T cells, resulting in distinct CD8+ T cell specificities and a surprisingly broad and variable Ag-specific CD4+ repertoire in different individuals.
|

Whereas anti-vaccine CTL were rare in the blood and inside metastases of this patient, anti-tumor CTL recognizing other tumor Ags, mainly MAGE-C2, were 100 times more frequent in the blood and considerably enriched in metastases following vaccination.

18292586
|
Anti-MAGE-3.A1 CD8 and anti-MAGE-3.DP4 CD4 T cells became detectable in the blood after vaccination at a frequency of approximately 10(-5) among the CD8 or CD4 T cells, respectively, and they were slightly enriched in slowly progressing metastases.
|
122 |
18292586
|
Additional anti-tumor CTL were present in the blood at a frequency of 2x10(-4) among the CD8 T cells and, among these, an anti-MAGE-C2 CTL clone was detected only following vaccination and was enriched by >1,000-fold in metastases relative to the blood.

In this study, we present evidence that the selectivity of CD4 T cell responses to peptides contained within protein Ags is not detectably influenced by the location of the peptide in a given protein or the primary sequence of the protein that bears the test peptide.
|
128 |
18713974
|
Collectively, these results suggest immunodominance of peptides contained in complex Ags is due to an intrinsic factor of the peptide, based upon the affinity of that peptide for MHC class II molecules.

Immunization with hsp110- or grp170-tyrosinase-related protein 2 (TRP2(175-192)) peptide complexes effectively primed CD8(+) T cells reactive with TRP2-derived, MHC class I-restricted epitope.
|
140 |

We asked whether the efficacy of dendritic cell (DC) vaccination with the renal cell carcinoma Ags MAGE-A9 (MAGE9) and G250 could be strengthened by covaccination with the renal cell carcinoma autoantigen GOLGA4.
|
145 |
20548033
|
Autoantigen covaccination significantly strengthened tumor Ag-specific CD4(+) and CD8(+) T cell expansion, particularly in peptide-loaded DC-vaccinated mice.
|
146 |
20548033
|
Covaccination was accompanied by an increase in inflammatory cytokines, boosted IL-12 and IFN-gamma expression, and promoted a high tumor Ag-specific CTL response.
|
147 |
20548033
|
Concomitant autoantigen vaccination also supported CCR6, CXCR3, and CXCR4 upregulation and T cell recruitment into the tumor.

21149605
|
We generated two novel targeting proteins consisting of the full-length NY-ESO-1 fused to the C terminus of two human mAbs against the human mannose receptor and DEC-205, both internalizing molecules expressed on APC.
|
154 |
21149605
|
These targeting proteins were evaluated for their ability to activate NY-ESO-1-specific human CD4(+) and CD8(+) T cells in vitro.
|
155 |
21149605
|
Whereas nontargeted and Ab-targeted NY-ESO-1 proteins similarly activated CD4(+) T cells, cross-presentation to CD8(+) T cells was only efficiently induced by targeted NY-ESO-1.
|
156 |
21149605

A Salmonella vector vaccine expressing the saliva-binding region (SBR) of the adhesin AgI/II of Streptococcus mutans has been shown to induce a mixed Th1/Th2 anti-SBR immune response in mice and to require Toll-like receptor 2 (TLR2), TLR4, and MyD88 signaling for the induction of mucosal anti-SBR antibody responses.
|
177 |
21746857
|
Bone marrow-derived DC from wild-type and TLR2, TLR4, and MyD88 knockout mice were stimulated with Salmonella vector BRD509, the SBR-expressing Salmonella vector vaccine BRD509(pSBRT7), or SBR protein, and the DC responses to different stimuli were compared by assessing costimulatory molecule expression, cytokine production, and signaling pathways.
