Strategies to overcome this include up-regulation of MHC and introduction of cell adhesion molecules into tumor cells, suppression of transforming growth factor and interleukin 10 production by tumor cells, and blockade of the fas ligand-fas interaction between tumor cells and attacking lymphocytes.

We have earlier demonstrated a significant role for IL-12 in the regression of a rat histiocytic tumor, AK-5.
|
17 |

|
Analysis of the serum samples from animals injected with the IL-12 gene-transfected AK-5 cells on different days revealed a significant increase in circulatory IL-12, interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha and antitumor antibodies, all of which contributed to the reduction in tumor mass.
|
18 |
10390075
|
Similarly, intraperitoneal transplantation of IL-12 gene-transfected tumor cells in syngeneic Wistar rats induced a significant increase in cellular cytotoxicity, with a concomitant reduction in circulatory IL-12 (p40) protein.
|

We show that macrophages are sensitive to sTat stimulation at concentrations 1,000-fold lower (500 pM) than T cells, and this stimulation is accompanied by the immunosuppressive induction of Fas ligand on the macrophage.
|

Interleukin (IL)-18 is a newly discovered cytokine, structurally similar to IL-1, with profound effects on T-cell activation.
|
38 |
10525448
|
Formerly called interferon (IFN) gamma inducing factor (IGIF), IL-18 is the new name of a novel cytokine that plays an important role in the T-cell-helper type 1 (Th1) response, primarily by its ability to induce IFNgamma production in T cells and natural killer (NK) cells.
|
39 |
10525448
|
Mice deficient in IL-18 have suppressed IFNgamma production despite the presence of IL-12 IL-18 is related to the IL-1 family in terms of structure, receptor family, and function.
|
40 |
10525448
|
In terms of structure, IL-18 and IL-1beta share primary amino acid sequences of the so-called "signature sequence" motif and are similarly folded as all-beta pleated sheet molecules.
|
41 |
10525448
|
Also similar to IL-1beta, IL-18 is synthesized as a biologically inactive precursor molecule lacking a signal peptide which requires cleavage into an active, mature molecule by the intracellular cysteine protease called IL-1beta-converting enzyme (ICE, also called caspase-1).
|
42 |
10525448
|
The activity of mature IL-18 is closely related to that of IL-1.
|
43 |
10525448
|
IL-18 induces gene expression and synthesis of tumor necrosis factor (TNF), IL-1, Fas ligand, and several chemokines.
|
44 |
10525448
|
This IL-18R complex is made up of a binding chain termed IL-18Ralpha, a member of the IL-1 receptor family previously identified as the IL-1 receptor-related protein (IL-1Rrp), and a signaling chain, also a member of the IL-1R family.
|
45 |
10525448
|
The IL-18R complex recruits the IL-1R-activating kinase (IRAK) and TNFR-associated factor-6 (TRAF-6) which phosphorylates nuclear factor kappaB (NFkappaB)-inducing kinase (NIK) with subsequent activation of NFkappaB.
|
46 |
10525448
|
Thus on the basis of primary structure, three-dimensional structure, receptor family, signal transduction pathways and biological effects, IL-18 appears to be a new member of the IL-1 family.
|
47 |
10525448
|
Similar to IL-1, IL-18 participates in both innate and acquired immunity.
|
48 |
10601552
|
Human tumor antigens when presented appropriately (with costimulatory molecules and with IL-2, IL-12) break the host's natural tolerance toward its tumor and induce rejection strength immune reactions even in patients with metastatic disease.

|
For successful active specific immunization against human cancers the understanding of the immunoevasive maneuvers of the tumor cell (through FasL --> Fas; TRAIL; CD40L --> CD40; TGFbeta etc. systems) is essential.

Involvement of the apoptosis-mediating CD95/CD95 ligand system in MS has been demonstrated.
|
68 |

|
Here, we report that (auto)antigen-specific human T cells are not killed in vitro by soluble TNF-related apoptosis-inducing ligand (TRAIL) although expressing death-inducing receptors, TRAIL receptor 1 (TRAIL-R1) and TRAIL-R2.
|
69 |
10889508
|
The (auto)antigen-specific T cells were also resistant to specific TRAIL-R1/TRAIL-R2-directed induction of apoptosis, indicating that coexpression of the truncated TRAIL-R3 and TRAIL-R4 in these T cells is not responsible for the observed resistance.
|
70 |

|
In contrast to CD95, the role of TRAIL receptors in MS might not involve regulation of T cell vulnerability.

To analyze immune requirements, we immunized gene knockout (KO) mice of C57BL/6 background, deficient in either CD3, CD4, CD8, interferon gamma (IFNgamma), perforin or Fas ligand (FasL).
|
85 |
11021590
|
Only CD3+ mice expressing both CD4 and CD8, which appear equally important, as well as IFNgamma and perforin, could fully resist a tumor challenge.
|

CEA-stimulated IFNgamma production occurred in both CD4- or CD8-KO mice and in both cases was augmented by IL-12.

|
CD4+ alpha beta T cells and gamma interferon (IFN-gamma) are centrally implicated in the primary immunoprotective response.
|
88 |
11035735
|
We find that a full-strength primary response depends on beta(2)-microglobulin (class I major histocompatibility complex [MHC] and class II MHC and on IFN-gamma and interleukin-6 (IL-6) but not on TAP1, perforin, IL-4, Fas ligand, or inducible nitric oxide synthetase.
|

|
Indeed, MHC class II-deficient and IFN-gamma-deficient mice are as susceptible to primary infection as mice deficient in all alpha beta T cells.
|

Strikingly, the requirements for a highly effective alpha beta-T-cell-driven memory response are less stringent, requiring neither IFN-gamma nor IL-6 nor class I MHC.

The elimination of CD8+ T cells from splenic cells significantly reduced their inhibitory action on parasite proliferation as well as their cytotoxic activity against RH-infected macrophages, but it did not affect the production of IFN-gamma.

103 |
11722643
|
Treatment of CD8+ T-enriched splenic cells from the immunized mice with concanamycin A, but not an anti-Fas ligand monoclonal antibody, significantly reduced their anti-proliferative and killing capabilities, suggesting that the CD8+ T cells induced by immunization with RH antigen and live bradyzoites of the Beverley strain may exert protection against T. gondii infection at least in part through granule-dependent cytotoxic activities.

Cutting edge: a novel role for Fas ligand in facilitating antigen acquisition by dendritic cells.

Fas ligand (FasL)-expressing tumor cells are found to effectively mediate rejection of the coinoculated FasL negative parental cells while having no effect on the growth of histologically distinct tumor cells.
|
116 |
12193688
|
Indeed, tumor cells expressing FasL can efficiently interact with dendritic cells (DCs) and this interaction requires the expression of membrane-bound FasL on tumors and Fas on DCs.
|
117 |

Moreover, DCs cocultured with FasL-expressing tumors are able to elicit a tumor-specific immune response in vivo, suggesting that DCs acquire tumor Ag during the Fas/FasL-mediated DC-tumor contact.

During the primary response, there was a significant defect in both the generation and in vivo effector function of Ad-specific CTLs in CD28-/- mice, but not in CD4+ T cell-depleted mice or CD4-/- mice.
|

|
In the absence of perforin, production of FasL, but not TNF-alpha, by the CTLs results in lower level Ad-specific killing of target cells.

Experimental evidence suggests a role for Bcl-2 and CD95L in the inhibition of programmed cell death in UV-induced skin cancer or malignant melanoma cells.
|

|
Development of novel vaccines should therefore take into consideration the effects on central markers to obtain a better picture of regulation of immunity, including FasL and Bcl-2 which are essential in regulation of apoptosis.

|
Moreover, effector and/or memory phenotype CD8 T cells were responsible, because adoptive transfer of purified CD44(high) CD8 T cells to naive mice induced fatal responses following a primary low-dose infection.
|
254 |
16982903
|
The fatal responses were perforin- and Fas ligand-independent, and were associated with high serum concentrations of TNF-alpha and CCL2, and low levels of IL-10.
|
255 |
16982903
|
Accordingly, blockade of either TNF-alpha or CCL2 ameliorated fatal recall responses, and in vitro coculture of memory CD8 T cells and Ixodes ovatus ehrlichia-infected peritoneal exudate cells resulted in substantial increases in TNF-alpha and CCL2.

Immunization of cattle with a Leptospira borgpetersenii serovar hardjo-bovis vaccine results in the development of a recall response by WC1(+) gammadelta T cells and CD4(+) alphabeta T cells characterized by proliferation and interferon-gamma production.
|
257 |
17081609
|
Both T cell populations had similar transcript profiles for effector molecules, including IFN-gamma, FasL and granzyme B.
|
258 |
17081609
|
In contrast, transcripts for costimulatory receptors and ligands were notably different following activation, as WC1(+) T cells expressed no or lower levels of transcripts for CD28 and CD40L, while CD4(+) T cells expressed substantial levels of both.
|
259 |
17081609
|
These results strengthen the hypothesis that these particular activated WC1(+) and CD4(+) T cells have overlapping effector functions and therefore may differ principally with regard to how they are recruited into immune responses.

BALB/c mice received three preventive intraperitoneal immunizations with Mage-b DNA vaccine mixed with plasmid DNA, secreting granulocyte-macrophage colony stimulating factor (GM-CSF).
|
277 |
18094967

Immunization with Mage-b/GM-CSF/TGB significantly reduced the number of metastases by 67% compared to the saline/GM-CSF/TGB and by 69% compared to the vector control/GM-CSF/TGB.
|
278 |

|
280 |
18094967

A single dose of Y-90-labeled anti-CEA mAb, in combination with vaccine therapy, resulted in a statistically significant increase in survival in tumor-bearing mice over vaccine or mAb alone; this was shown to be mediated by engagement of the Fas/Fas ligand pathway.
|
289 |
18256832

For gene-based vaccination against B16 melanoma in C57BL/6JNarl mice, initial priming with mouse RANTES cDNA followed 24 h later by human gp100 DNA vaccination, and later boosting with a viral vector expressing mRANTES and hgp100 strongly suppressed B16/hgp100 primary tumors and lung metastasis.
|
437 |

Multiple immune-effector molecules play a role in antimicrobial immunity mediated by memory CD8 T cells, including IFN-gamma, perforin, TRAIL, Fas ligand, and TNF-alpha.
|
439 |
20097864
|
Our studies reveal that endogenous memory CD8 T cell-mediated protection against both parasite species is, in part, dependent on IFN-gamma, whereas perforin was only critical in protection against P. yoelii.
|
440 |
20097864
|
We further show that neutralization of TNF-alpha in immunized mice markedly reduces memory CD8 T cell-mediated protection against both parasite species.
|
441 |

|
Thus, our studies identify IFN-gamma and TNF-alpha as important components of the noncytolytic pathways that underlie memory CD8 T cell-mediated immunity against liver stage Plasmodium infection.

|
454 |
21076072

Engineering lentiviruses to display this Ab endowed them with the same specificity as the Ab, whereas coexpressing the Ab and Fas ligand enables the lentiviruses to kill specifically Nef-presenting cells.

Suppressor of cytokine signaling-1 (SOCS1) is a key negative regulator of the JAK/STAT signal pathway and plays an essential role in suppressing systemic autoimmunity that is mediated by DCs.
|
456 |
21479379
|
In the mouse melanoma model, we found that a 2x106 TRP2-pulsed DC vaccine was able to induce immune tolerance, while a 2x106 SOCS1-silenced DC/TRP2 vaccine prevented immune tolerance.
|
457 |
21479379
|
Further experiments revealed that activation-induced T cell death (AICD) through the Fas/Fas-L pathway may play a crucial role in immune tolerance induced by 2x106 TRP2-pulsed DC.
|
458 |
21479379
|
SOCS1-silencing in DCs could prevent immune tolerance by inhibiting Fas and Fas-L expression, induced by an increase in IL-12p70 and IL-6 production.
|
459 |
21479379
|
In addition, in 2x106 SOCS1-silenced DC/TRP2 immunized mice, higher levels of IL-12p70 and IFN-γ and lower IL-17 production may inhibit tumor angiogenesis and therefore assist in breaking immune tolerance.

Notwithstanding marked expression of the natural killer (NK) cell marker CD56 on a subset of IL-15 DCs, we found no evidence of a further phenotypic overlap between IL-15 DCs and NK cells.
|
468 |
23284789
|
The cytotoxicity of IL-15 DCs is predominantly mediated by granzyme B and, to a small extent, by tumor necrosis factor-α (TNF-α)-related apoptosis-inducing ligand (TRAIL) but is independent of perforin, Fas ligand and TNF-α.

Furthermore, α-GalCer-induced egr-2/3 in hepatic NKT cells upregulated their TRAIL in addition to Fas ligand (FasL) and induced alarm signaling molecule IL-33 in Kupffer cells, presumably because of liver damage triggered by TRAIL/FasL.

Thus, α-GalCer-induced FasL/TRAIL and IL-33 provided a novel mechanism underlying α-GalCer-induced hepatotoxicity and MDSC accumulation.

The vaccination site eventually became a T cell graveyard where T cells responded to chronically released gp100 peptide by releasing cytokines, including interferon-γ (IFN-γ), which in turn upregulated Fas ligand (FasL) on host cells, causing apoptosis of Fas(+) T cells.

The rapid killing of macrophages induced by Y. pestis, dependent upon type III secretion system effector Yersinia outer protein J (YopJ), is minimally affected by the absence of caspase-1, caspase-11, Fas ligand, and TNF.
|
486 |
24799678
|
Here we provide genetic evidence for a receptor-interacting protein (RIP) kinase-caspase-8-dependent macrophage apoptotic death pathway after infection with Y. pestis, influenced by Toll-like receptor 4-TIR-domain-containing adapter-inducing interferon-β (TLR4-TRIF).
|
487 |
24799678
|
Interestingly, macrophages lacking either RIP1, or caspase-8 and RIP3, also had reduced infection-induced production of IL-1β, IL-18, TNF, and IL-6; impaired activation of the transcription factor NF-κB; and greatly compromised caspase-1 processing.
|
488 |
24799678
|
Cleavage of the proform of caspase-1 is associated with triggering inflammasome activity, which leads to the maturation of IL-1β and IL-18, cytokines important to host responses against Y. pestis and many other infectious agents.
|
489 |
24799678
|
Our results identify a RIP1-caspase-8/RIP3-dependent caspase-1 activation pathway after Y. pestis challenge.

|
Mice defective in caspase-8 and RIP3 were also highly susceptible to infection and displayed reduced proinflammatory cytokines and myeloid cell death.
|
491 |
24799678

We propose that caspase-8 and the RIP kinases are key regulators of macrophage cell death, NF-κB and inflammasome activation, and host resistance after Y. pestis infection.

This combination therapy also increased TILs, including tumor antigen-specific CD8 T cells, and elevated the expression of activation markers FAS-L, CXCL-9, CD31, and CD105 in MDSCs and TAMs, leading to reduced tumor volumes and an increase in the number of tumor-free animals.

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.

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.

Unlike previously reported CD4 CTLs, the transcription factors Tbet and Eomes were not necessary for their development.

CTL activity was also independent of the Fas ligand-Fas, TRAIL-DR5, and canonical death pathways, indicating a novel mechanism of CTL activity.

Rather, the in vivo CD4 CTL activity induced by vaccination required T cell expression of CD154 (CD40L) and target cell expression of CD40.

Thus, vaccination with a TLR4 agonist adjuvant induces CD4 CTLs, which kill through a previously unknown CD154-dependent mechanism.
