However, we provide strong evidence for the interpretation that programming of long-lived memory T cells was driven by low levels of transcription factor eomesodermin and protease inhibitor Spi2A as well as reduced phosphorylation of c-JUN.

The number of T-bet(+) TILs correlates with better survival of esophageal cancer patients.

|
Using well-defined mouse models, we have further shown that T-bet and Eomes are both required for the adaptive anti-tumor immunity by regulating T-cell trafficking into the tumor tissue and their effector functions inside the tumor microenvironment.
|
31 |
21717068
|
In order to gain further insight into the tumor immune microenvironment in the upper GI cancer, we have also studied expression levels of co-inhibitory molecules such as B7-H1/PD-L1 and B7-H4 in tissue specimens of esophageal and gastric cancers.
|
32 |
21717068
|
The number of CD3(+) and CD8(+) TILs correlates inversely with expression levels of B7-H4 in samples from esophageal cancer, supporting a role of active immune suppression by inhibitory B7 molecules in the tumor microenvironment.
|
33 |
21717068
|
In addition, TILs show functional exhaustion and express high levels of PD-1 and Tim-3.
|

We have previously shown that vaccination with the natural tumor peptide Melan-A-induced T cells with superior effector functions as compared with vaccination with the analog peptide optimized for enhanced HLA-A*0201 binding.
|
42 |
22735807
|
Here we found that natural peptide vaccination induced tumor-reactive CD8 T cells with frequent coexpression of both memory/homing-associated genes (CD27, IL7R, EOMES, CXCR3, and CCR5) and effector-related genes (IFNG, KLRD1, PRF1, and GZMB), comparable with protective Epstein-Barr virus-specific and cytomegalovirus-specific T cells.

T-box transcription factors T-bet (Tbx21) and Eomesodermin (Eomes) are critical players in CD8(+) cytotoxic T lymphocyte effector function and differentiation, but how the expression of these transcription factors is regulated remains poorly defined.
|
44 |
22942184
|
Here we show that dominant T cells directed toward human CMV, expressing significantly higher levels of T-bet with graded loss of Eomes expression (T-bet(hi)Eomes(hi/lo)), are more efficient in recognizing endogenously processed peptide-major histocompatibility complexes (pMHC) compared with subdominant virus-specific T cells expressing lower levels of T-bet and high levels of Eomes (T-bet(int)Eomes(hi)).
|
45 |
22942184
|
Paradoxically, the T-bet(hi)Eomes(hi/lo) dominant populations that efficiently recognized endogenous antigen demonstrated lower intrinsic avidity for pMHC, whereas T-bet(int)Eomes(hi) subdominant populations were characterized by higher pMHC avidity and less efficient recognition of virus-infected cells.
|
46 |
22942184
|
Importantly, differential endogenous viral antigen recognition by CMV-specific CD8(+) T cells also correlated with the differentiation status and expression of perforin, granzyme B and K.
|
47 |
22942184
|
Furthermore, we demonstrate that the expression of T-bet correlates with clonal expansion, differentiation status, and expression of perforin, granzyme B and K in antigen-specific T cells.

We observed the loss of the short-lived effector cell phenotype (reduced KLRG1(+), T-bet(hi), granzyme B(hi)), accompanied by an enhanced memory precursor phenotype at the effector (increased CD127(hi), IL-2(+)) and contraction phases (increased CD127(hi), IL-2(+), eomesodermin(hi)) of the CD8 response in the absence of RA signaling.

CD8α+ dendritic cell trans presentation of IL-15 to naive CD8+ T cells produces antigen-inexperienced T cells in the periphery with memory phenotype and function.
|
60 |
23355737
|
The absence of IL-15, CD8(+) T cell expression of either CD122 or eomesodermin or of CD8a(+) dendritic cells all lead to the loss of VM cells in the host.
|
61 |
23355737
|
Our results show that CD8(+) T cell homeostatic expansion is an active process within the nonlymphopenic environment, is mediated by IL-15, and produces Ag-inexperienced memory cells that retain the capacity to respond to nominal Ag with memory-like function.

TNF-α(+) and IFN-γ(+) CD4(+) T cells expressed significantly higher levels of T-box transcription factors T-bet with graded loss of Eomesodermin (Eomes) expression (T-bet(Hi)Eomes(Hi/Lo)) when compared with TNF-α(+) CD4(+) T cells expressing lower levels of both T-bet and Eomes (T-bet(-)Eomes(-)).
|
63 |
24296812
|
Furthermore, TNF-α(+) and IFN-γ(+) CD4(+) T cells expressed significantly higher levels of perforin and interleukin (IL)-2 and displayed a terminally differentiated phenotype (CCR7(-)CD27(-)CD45RA(-)CD57(+)CD62L(-)).
|
64 |
24296812
|
In contrast, TNF-α(+) alone CMV-specific CD4(+) T cells were predominantly early-memory phenotype with a proportion of these cells displaying T memory stem-cell phenotype (CD95(+)CD45RA(+)CCR7(+)CD27(+)).
|
65 |
24296812
|
In vitro stimulation of CMV-specific CD4(+) T cells with viral antigen in the presence of IL-12 was sufficient to dramatically change the transcriptional and functional profile of TNF-α(+) CD4(+) T cells, whereas TNF-α(+) and IFN-γ(+) CD4(+) T cells remained unaltered.

Longitudinal requirement for CD4+ T cell help for adenovirus vector-elicited CD8+ T cell responses.
|
68 |
24778441
|
Our data demonstrate that induction and maintenance of CD8(+) T cell responses by Ad vector immunization is longitudinally dependent on CD4(+) T cell help for a prolonged period.
|
69 |
24778441
|
Depletion of CD4(+) T cells in wild type mice within the first 8 d following Ad immunization resulted in dramatically reduced induction of Ag-specific CD8(+) T cells, decreased T-bet and eomesodermin expression, impaired KLRG1(+) effector differentiation, and atypical expression of the memory markers CD127, CD27, and CD62L.
|
70 |
24778441
|
Depletion of CD4(+) T cells between weeks 1 and 4 following immunization resulted in increased contraction of memory CD8(+) T cells.
|
71 |
24778441
|
These data demonstrate a prolonged temporal requirement for CD4(+) T cell help for vaccine-elicited CD8(+) T cell responses in mice.
|
72 |
24778441
|
These findings have important implications in the design of vaccines aimed at eliciting CD8(+) T cell responses and may provide insight into the impaired immunogenicity of vaccines in the context of AIDS and other CD4(+) T cell immune deficiencies.

Combination of 4-1BB agonist and PD-1 antagonist promotes antitumor effector/memory CD8 T cells in a poorly immunogenic tumor model.
|
74 |
25387892
|
The activity of the anti-4-1BB/anti-PD-1 combination was dependent on IFNγ and CD8(+) T cells.
|
75 |
25387892
|
Both 4-1BB and PD-1 proteins were elevated on the surface of CD8(+) T cells by anti-4-1BB/anti-PD-1 cotreatment.
|
76 |
25387892
|
In the tumor microenvironment, an effective antitumor immune response was induced as indicated by the increased CD8(+)/Treg ratio and the enrichment of genes such as Cd3e, Cd8a, Ifng, and Eomes.

The tyrosine kinase Itk suppresses CD8+ memory T cell development in response to bacterial infection.
|
78 |
25567129
|
Here, we have examined the role of Itk, a tyrosine kinase critical for TcR signaling, in CD8(+) effector and memory T cell differentiation during Listeria monocytogenes infection.
|
79 |
25567129
|
We found that the reduced TcR signal strength in Itk deficient naïve CD8(+) T cells enhances the generation of memory T cells during infection.
|
80 |
25567129
|
Our data suggests that Itk-mediated signals control the expression of Eomesodermin and IL-7Rα, thus regulating the development of memory CD8(+) T cells, but not subsequent response of memory cells.
|

Transcription factor expression patterns in SIV-specific CD8+ T cells in SIVΔnef-vaccinated animals were distinct from those observed in purified CD8+ T cell subsets obtained from naïve animals, and were intermediate to expression profiles of purified central memory and effector memory T cells.
|
82 |
25768938
|
Expression of transcription factors associated with effector differentiation, such as ID2 and RUNX3, were decreased over time, while expression of transcription factors associated with quiescence or memory differentiation, such as TCF7, BCOR and EOMES, increased.
|
83 |

|
CD8+ T cells specific for a more conserved epitope expressed higher levels of TBX21 and BATF, and appeared more effector-like than cells specific for an escaped epitope, consistent with continued activation by replicating vaccine virus.

Dengue virus infection elicits highly polarized CX3CR1+ cytotoxic CD4+ T cells associated with protective immunity.
|
85 |
26195744
|
Although DENV-specific CD8(+) T-cell responses have been extensively studied, the breadth and specificity of CD4(+) T-cell responses remains to be defined.
|
86 |
26195744
|
Ex vivo flow-cytometric analysis of DENV-specific CD4(+) T cells revealed that the virus-specific cells were highly polarized, with a strong bias toward a CX3CR1(+) Eomesodermin(+) perforin(+) granzyme B(+) CD45RA(+) CD4 CTL phenotype.

CD161(int)CD8+ T cells: a novel population of highly functional, memory CD8+ T cells enriched within the gut.
|
88 |
26220166
|
Here we show that CD161 is also expressed, at intermediate levels, on a prominent subset of polyclonal CD8+ T cells, including antiviral populations that display a memory phenotype.
|
89 |
26220166
|
These memory CD161(int)CD8+ T cells are enriched within the colon and express both CD103 and CD69, markers associated with tissue residence.
|
90 |
26220166
|
Furthermore, this population was characterized by enhanced polyfunctionality, increased levels of cytotoxic mediators, and high expression of the transcription factors T-bet and eomesodermin (EOMES).
|
91 |
26220166
|
Thus, intermediate CD161 expression marks potent polyclonal, polyfunctional tissue-homing CD8+ T-cell populations in humans.

Vaccination Produces CD4 T Cells with a Novel CD154-CD40-Dependent Cytolytic Mechanism.
|
93 |
26297758
|
We demonstrate that immunization with a recombinant protein Ag and GLA-SE also induces granzyme A expression in CD4 T cells and produces cytolytic cells that can be detected in vivo.
|
94 |
26297758
|
Surprisingly, these in vivo CTLs were CD4 T cells, not CD8 T cells, and this cytolytic activity was not dependent on granzyme A/B or perforin.
|
95 |
26297758
|
Unlike previously reported CD4 CTLs, the transcription factors Tbet and Eomes were not necessary for their development.
|
96 |
26297758
|
CTL activity was also independent of the Fas ligand-Fas, TRAIL-DR5, and canonical death pathways, indicating a novel mechanism of CTL activity.
|
97 |
26297758
|
Rather, the in vivo CD4 CTL activity induced by vaccination required T cell expression of CD154 (CD40L) and target cell expression of CD40.
|
98 |
26297758
|
Thus, vaccination with a TLR4 agonist adjuvant induces CD4 CTLs, which kill through a previously unknown CD154-dependent mechanism.

Antibody modulation of T-cell coinhibitory (e.g., CTLA-4) or costimulatory (e.g., 4-1BB) receptors promotes clinical responses to a variety of cancers.

26351680
|
Combining this E6/E7 peptide vaccine with checkpoint blockade produced only modest benefit; however, coadministration with a 4-1BB agonist antibody promoted durable regression of established genital TC-1 tumors.
|
101 |
26351680
|
Relative to other therapies tested, this combination of vaccine and α4-1BB promoted the highest CD8(+) versus regulatory FoxP3(+) T-cell ratios, elicited 2- to 5-fold higher infiltration by E7-specific CTL, and evoked higher densities of highly cytotoxic TcEO (T cytotoxic Eomesodermin) CD8 (>70-fold) and ThEO (T helper Eomesodermin) CD4 (>17-fold) T cells.
