Here, we demonstrate that in CD8+ T cells, Cbx3/HP1γ insufficiency leads to chromatin remodeling accompanied by enhanced Prf1, Gzmb and Ifng expression.
|

28220815
|
In tumors obtained from Cbx3/HP1γ-insufficient mice or wild type mice treated with Cbx3/HP1γ-insufficient CD8+ T cells, there is an increase of CD8+ effector T cells expressing the stimulatory receptor Klrk1/NKG2D, a decrease in CD4+ CD25+ FOXP3+ regulatory T cells (Treg cells) as well as CD25+ CD4+ T cells expressing the inhibitory receptor CTLA4.

Virus-specific CD8+ T cell responses have been investigated extensively through the use of HLA-peptide tetramers but much less is known regarding CMV-specific CD4+ T cells.
|
14 |
27606804
|
CMV-specific CD4+ T cells display a highly differentiated effector memory phenotype and express a range of cytokines, dominated by dual TNF-α and IFN-γ expression, although substantial populations which express IL-4 were seen in some donors.
|
15 |
27606804
|
These include the expression of CX3CR1, which would direct cells towards fractalkine on activated endothelium, and the β2-adrenergic receptor, which could permit rapid response to stress.
|
16 |
27606804
|
CMV-specific CD4+ T cells display an intense cytotoxic profile with high level expression of granzyme B and perforin, a pattern which increases further during aging.

Human HLA-A*02:01/CHM1+ allo-restricted T cell receptor transgenic CD8+ T cells specifically inhibit Ewing sarcoma growth in vitro and in vivo.
|
18 |
27281613
|
However, utilization of these cells in current therapy protocols is hampered due to high complexity in production, relatively low cell numbers, and rapid T cell exhaustion.In order to provide off-the-shelf products in the future, we successfully generated HLA-A*02:01-restricted T cell receptor (TCR) transgenic T cells directed against CHM1319 by retroviral transduction.After short-term expansion a 100% purified CHM1319-TCR-transgenic T cell population expressed a CD62L+/CD45RO and CD62L+/CD45RA+ phenotype.
|
19 |
27281613
|
These cells displayed specific in vitro IFNg and granzyme B release in co-culture with HLA-A*02:01+ ES cell lines expressing CHM1.
|

|
When co-injected with ES cells in Rag2-/-É£c-/- mice, CHM1-specific TCR-transgenic T cells significantly inhibited the formation of lung and liver metastases in contrast to control mice.

We found that the cell surface molecule platelet endothelial cell adhesion molecule-1 (PECAM-1) facilitated noncanonical (Smad-independent) TGF-β signaling in T cells.
|
22 |
26956486
|
T cells isolated from PECAM-1(-/-) mice demonstrated relative insensitivity to the TGF-β-dependent inhibition of interferon-γ (IFN-γ) production, granzyme B synthesis, and cellular proliferation.
|
23 |
26956486
|
Co-incubation of T cells with TGF-β and a T cell-activating antibody resulted in PECAM-1 phosphorylation on an immunoreceptor tyrosine-based inhibitory motif (ITIM) and the recruitment of the inhibitory Src homology 2 (SH2) domain-containing tyrosine phosphatase-2 (SHP-2).

Quantitative PCR analysis revealed that overexpression of IL-15/sIL-15Rα induced the activation of natural killer and T cells, evidenced by increased mRNA levels of marker genes including granzyme B, perforin, Ifn-γ, T-bet and Cd8 in the lungs, liver and kidneys.
|
25 |
26742578
|
Taken together, these results suggest that IL-15/sIL-15Rα-based gene therapy could be an effective approach to treat late-stage lung cancer with metastases in other organs.

Next to upregulation of NK-cell membrane activation markers, IL-15 transpresentation resulted in increased NK-cell secretion of IFN-γ, granzyme B and perforin.
|

|
In the complete response (CR) cases, 999 overexpressed genes including at least 234 tumor-specific CTL-activation associated genes such as IFNG, PRF1, and GZMB, were found in post-treatment biopsy specimens.
|
28 |
26625258
|
Furthermore, NK cells, which were activated by neutrophils-producing S100A8/S100A9, and CTLs were suggested to cooperatively enhance the effect of CRT in the CDH2-negative I-type.

|
They are mainly detectable in the CD8(+) and CD8(-) CD4(-) "double negative" T-cell compartments of mammals and exhibit both Th1- and Th17-associated features.
|
31 |
26046663
|
We demonstrate that in the absence of TCR cross-linking, human MAIT cells secrete IFN-γ, increase perforin expression and switch on granzyme B production in response to IL-15.
|
32 |
26046663
|
As this mechanism was dependent on the presence of CD14(+) cells and sensitive to IL-18 blockade, we identified IL-15 induced IL-18 production by monocytes as an inflammatory, STAT5-dependent feedback mechanism predominantly activating the MAIT-cell population.

|
Inhibition of HO-1 via SnMP in cytomegalovirus (CMV)pp65-peptide-pulsed peripheral blood mononuclear cells (PBMCs) led to increased anti-viral T cell activation and the generation of a higher proportion of effector memory T cells (CD45RA(-) CD62L(-)) with increased capability to secrete interferon (IFN)-γ and granzyme B.
|
34 |
25196646
|
Compared to control, SnMP treatment resulted in higher cell counts and purity without negative impact on quality and effector function [CD107a, IFN-γ and tumour necrosis factor (TNF)-α levels were stable].

|
We found that IL-15 improves NK cell viability, granzyme B expression, degranulation capacity and interferon-γ (IFNγ) secretion independently of PKC-θ.
|
36 |
25960930
|
Furthermore, IFNα induces PKC-θ auto-phosphorylation in NK cells, in a signal transduction pathway involving both phosphatidylinositol-3-kinase (PI3K) and phospholipase-C (PLC) activation.
|
37 |
25960930
|
PKC-θ dependence was further implicated in IFNα-induced transcriptional upregulation of chemokine (C-X-C motif) ligand 10 (CXCL10), a signal transducer and activator of transcription-1 (STAT-1)-dependent target of IFNα.
|
38 |
25960930
|
The absence of PKC-θ did not affect IFNα-induced STAT-1 Tyr701 phosphorylation but affected the increase in STAT-1 phosphorylation on Ser727, attenuating CXCL10 secretion.

Peripheral blood mononuclear cells of healthy donors and post-transplant lymphoma patients were stimulated with or without lunasin in the presence of IL-12 or IL-2.
|
40 |
24363024
|
Adding lunasin to IL-12- or IL-2-stimulated NK cells demonstrated synergistic effects in the induction of IFNG and GZMB involved in cytotoxicity.
|
41 |
24363024
|
The combination of lunasin and cytokines (IL-12 plus IL-2) was capable of restoring IFNγ production by NK cells from post-transplant lymphoma patients.

Here we show that human umbilical cord blood (UCB)-derived CD34+CD38-/low hematopoietic stem cells can be successfully differentiated into functional, antigen-specific cytotoxic CD8+ T cells without direct stromal coculture or retroviral TCR transfection.
|
43 |

|
Surface-immobilized Notch ligands (DLL1) and stromal cell conditioned medium successfully induced the development of CD1a+CD7+ and CD4+CD8+ early T cells.
|
44 |
23939944
|
These cells, upon continued culture with cytomegalovirus (CMV) or influenza-A virus M1 (GIL) epitope-loaded human leukocyte antigen (HLA)-A*0201 tetramers, resulted in the generation of a polyclonal population of CMV-specific or GIL-specific CD8+ T cells, respectively.
|
45 |
23939944
|
Upon further activation with antigen-loaded target cells, these antigen-specific, stem cell-derived T cells exhibited cytolytic functionality, specifically CD107a surface mobilization, interferon gamma (IFNg) production, and Granzyme B secretion.

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.
|
47 |
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.

Naturally occurring effector CD8(+) T cells, with a KLRG1(hi) CD62L(lo) phenotype typical of short-lived effector CD8(+) T cells (SLECs), can be found in increased numbers in autoimmune-prone mice, most notably in mice homozygous for the san allele of Roquin.
|
49 |
22685317
|
When Roquin is mutated (Roquin(san)), effector CD8(+) T cells accumulate in a cell-autonomous manner, most prominently as SLEC-like effectors.
|
50 |
22685317
|
Excessive IFN-γ promotes the accumulation of SLEC-like cells, increases their T-bet expression, and enhances their granzyme B production in vivo.
|
51 |
22685317
|
This study identifies a novel mechanism that prevents accumulation of self-reactive cytotoxic effectors, highlighting the importance of regulating Ifng mRNA stability to maintain CD8(+) T cell homeostasis and prevent CD8-mediated autoimmunity.
