A20 is a B cell lymphoma that constitutively expresses the costimulatory molecule B7-2 yet grows readily as a tumor in syngeneic BALB/c mice.
|
2 |
10202049
|
We have compared the tumorigenicity of A20 variants expressing either B7-1 (A20/B7-1) or B7-2 (A20/B7-2) with an A20 variant expressing B7-1 and B7-2 with 4-1BBL (A20/4-1BBL), a costimulatory member of the TNF family.
|

|
In contrast, mice injected with A20/4-1BBL were tumor free for the 150-day follow-up period, while 25% of mice injected with A20/B7-2 developed tumors.
|

10202049
|
Splenocytes from these mice showed high CTL lytic activity against the parental tumor, A20, as well as the syngeneic BALB/c lymphoma K46J, but showed background levels of lytic activity against the congenic SCID thymoma line ST-D2 or the allogeneic EL4 thymoma.
|

|
In vitro blocking experiments with anti-B7-1 plus anti-B7-2 and/or soluble 4-1BB receptor showed B7-1, B7-2, and 4-1BBL all contributed to the CTL activity.
|
6 |

|
Thus, the data show that neither B7-1 or B7-2 alone can confer full immunogenicity to the A20 lymphoma but that the addition of 4-1BBL results in a tumor that is highly immunogenic and can confer long-lasting protection against challenge with parental tumor in vivo.

Analysis of peptide-specific responses early after immunization by CTL assay, intracellular IFN-gamma staining, and IFN-gamma enzyme-linked immunospot assay (ELISPOT) indicated that CD8 T cell responses were reduced 3- to 10-fold in the absence of 4-1BB costimulation.
|
8 |
10679066
|
Moreover, when agonistic anti-4-1BB Ab was given, CD8 T cell responses in 4-1BBL-/- mice were augmented to levels similar to those in 4-1BBL+/+ mice.

The results presented here suggest that costimulatory receptors on CTL such as CD27, CD134 (4-1BB), and MHC class II are capable of directly interacting with the corresponding ligands on T-helper lymphocytes resulting in enhanced proliferation and survival of the CTL during the effector phase of antitumor immune responses.

In vivo triggering through 4-1BB enables Th-independent priming of CTL in the presence of an intact CD28 costimulatory pathway.
|
13 |

|
Triggering of 4-1BB, a member of the TNFR family, through in vivo administration of agonistic anti-4-1BB Ab delivers a powerful costimulatory signal to CTL.
|
14 |
11937526
|
Accordingly, blockade of the CD28-costimulatory pathway abrogates the capacity of agonistic anti-4-1BB Ab to trigger Th-independent CTL immunity.
|
15 |

4-1BB (CD137) is induced on activated CD4(+) and CD8(+) T cells and delivers a costimulatory signal upon binding the 4-1BB ligand (4-1BBL) expressed on antigen-presenting cells.
|
29 |
12496166
|
Induction of 4-1BB is dependent on activation via the T-cell receptor (TCR) and possibly CD28.

It was previously demonstrated that both an in vivo protein (pneumococcal surface protein A [PspA])- and polysaccharide (phosphorylcholine [PC] determinant of teichoic acid)-specific immunoglobulin (Ig) isotype response to Streptococcus pneumoniae was dependent on CD4(+) TCRalphabeta(+) T cells and B7-dependent costimulation through CD28.
|
31 |
12496166
|
However, injection of an agonistic anti-4-1BB monoclonal antibody (MAb), while having no significant effect on the anti-PC response, strongly inhibits the primary anti-PspA response, the generation of PspA-specific memory, and germinal center formation but does not induce a lasting state of tolerance.
|
32 |
12496166
|
This inhibition is independent of CD8(+) T cells and is associated with the expansion of CD4(+) T cells with an activated phenotype, which is partly dependent on B7-dependent costimulation.

We hypothesize that the concomitant expression of tumor antigen and anti-CD137 scFv effectively engages NK cells, monocytes and dendritic cells, as well as activated CD4(+) and CD8(+) T cells (all of which express CD137) so as to induce and expand a tumor-destructive Th1 response.
|
56 |
12601523

Mice transgenic for the HER-2/neu homologue, rat neu, were immunized with full-length rat neu cDNA given alone or in combination with plasmids encoding costimulatory molecules CD80 or CD86 and the ligand for CD137 (CD137L).
|
61 |
14578464
|
Immunization with plasmids encoding the neu antigen along with plasmids encoding CD137L and either CD80 or CD86 resulted in the generation of neu-specific antibodies that induced phopshorylation of the neu tyrosine kinase and inhibited the growth of cultured tumor cells overexpressing neu.
|
62 |

|
4-1BB (CD137) is a tumour necrosis factor receptor (TNFR) family member, expressed primarily on CD8 T cells after activation.
|
106 |
15270726
|
Signalling through 4-1BB has been reported to enhance CD8 T-cell expansion and to protect activated CD8 T cells from death, resulting in an enlarged memory population.
|
107 |
15270726
|
Although stimulating 4-1BB has been shown to significantly improve the immune response to weak immunogens such as tumours, little is known about its effect on the CD8 T-cell response to a powerful viral vector such as vaccinia.
|
108 |
15270726
|
To test 4-1BB's ability to improve the murine CD8 T cell response to a DNA prime, poxvirus boost vaccine, similar to those used for human immunodeficiency virus and simian immunodeficiency virus vaccines, we administered 4-1BB agonist antibody at the time of the poxvirus boost. 4-1BB stimulation increased the number of functional memory CD8 T cells by two- to fourfold.
|
109 |
15270726
|
However, we saw a similar enhancement at the peak of the response and in the memory phase, thus we found no evidence in the context of virus infection that 4-1BB stimulation could increase the percentage of CD8 T cells that survive the acute activation phase to become memory cells.
|
110 |
15270726
|
OX40 (CD134) is an analogous TNFR family member expressed primarily on activated CD4 T cells.

15270726

Signalling through 4-1BB has been reported to enhance CD8 T-cell expansion and to protect activated CD8 T cells from death, resulting in an enlarged memory population.
|
125 |
15270726

Although stimulating 4-1BB has been shown to significantly improve the immune response to weak immunogens such as tumours, little is known about its effect on the CD8 T-cell response to a powerful viral vector such as vaccinia.
|
126 |
15270726
|
To test 4-1BB's ability to improve the murine CD8 T cell response to a DNA prime, poxvirus boost vaccine, similar to those used for human immunodeficiency virus and simian immunodeficiency virus vaccines, we administered 4-1BB agonist antibody at the time of the poxvirus boost. 4-1BB stimulation increased the number of functional memory CD8 T cells by two- to fourfold.
|
127 |
15270726
|
However, we saw a similar enhancement at the peak of the response and in the memory phase, thus we found no evidence in the context of virus infection that 4-1BB stimulation could increase the percentage of CD8 T cells that survive the acute activation phase to become memory cells.

We wished to directly compare, for the first time, the capacity of B7-1, B7-2 and 4-1BB ligand (4-1BBL) costimulatory molecules to convert murine and human acute myeloid leukemia (AML) cells into whole vaccines. 32Dc-kit is a murine myeloid cell line, which develops an AML-like disease over a protracted period, emulating human AML disease development. 32Dc-kit cells were modified to express elevated levels of B7-1, B7-2 or 4-1BBL, and each led to tumor rejection, although only mice injected with 32Dc-kit/B7-2 cells were able to reject subsequent parental tumor cell challenge.

We tested the effect of combining PD ligand 1 (PD-L1) blockade with an agonistic regimen that induces 4-1BB costimulation during chronic LCMV infection.
|
237 |
21742975
|
There is a boosting effect in the rescue of LCMV-specific CD8 T cell responses after dual treatment with PD-L1 blockade and 4-1BB agonistic Abs when the amount and timing of 4-1BB costimulation are carefully controlled.
|
238 |
21742975
|
When PD-L1-blocking Abs are given together with a single low dose of anti-4-1BB agonistic Abs, there is an enhanced and stable expansion of viral-specific CD8 T cells.
|
239 |
21742975
|
Conversely, when blocking Abs to PD-L1 are given with a repetitive high dose of anti-4-1BB, there is an initial synergistic expansion of viral-specific CD8 T cells by day 7, followed by dramatic apoptosis by day 14.
|
240 |
21742975
|
However, whereas the high dose of anti-4-1BB plus PD-L1 blockade resulted in rebound of viral titers to original levels, the low dose of anti-4-1BB plus PD-L1 blockade resulted in a stable reduction of viral loads.

The co-signaling molecule, LIGHT, is particularly well suited for use in vaccine development as it delivers a potent co-stimulatory signal through the Herpes virus entry mediator (HVEM) receptor on T cells and facilitates tumor-specific T cell immunity.
|
252 |
21877247
|
However, because LIGHT binds two additional receptors, lymphotoxin β receptor and Decoy receptor 3, there are significant concerns that tumor-associated LIGHT results in both unexpected adverse events and interference with the ability of the vaccine to enhance antitumor immunity.

Inoculation of anti-HVEM scFv-expressing tumor results in a spontaneous tumor regression in CD4+ and CD8+ T cell-dependent fashion, associated with the induction of tumor-specific long-term memory.
|
254 |
21877247
|
Stimulation of HVEM and 4-1BB co-stimulatory signals by anti-HVEM scFv-expressing tumor vaccine combined with anti-4-1BB mAb shows synergistic effects which achieve regression of pre-established tumor and T cell memory specific to parental tumor.

Here, we evaluated the ability of intravenous administration of a blocking monoclonal antibody (mAb) directed against the negative costimulatory molecule CTLA-4, and an agonist mAb directed against the positive costimulatory molecule 4-1BB, either alone or in combination, to augment intramuscular SIV DNA immunizations.
|
256 |
21935390
|
Interestingly, although CTLA-4 blockade alone did not enhance IFN-γ responses it did increase the proliferative capacity of the CD4(+) and CD8(+) T cells.
|
257 |
21935390
|
Furthermore, the use of the CTLA-4 blocking antibody resulted in significantly higher viral loads during chronic infection compared to animals that received the 4-1BB mAb, likely due to the higher CD4(+) T cell proliferative responses which were driven by this adjuvant following immunization.

The vaccine triggered upregulation of the immune inhibitory PD-1 signaling pathway and PD-1 blockade dramatically enhanced the rHuAd5-hDCT + anti-4-1BB strategy, resulting in complete regression of growing tumors in > 70% of recipients.

The impact of the combined anti-4-1BB/anti-PD-1 treatment did not manifest as a dramatic enhancement in either the magnitude or functionality of DCT-specific tumor infiltrating lymphocytes relative to either treatment alone.

Targeting 4-1BB (CD137) to enhance CD8 T cell responses with poxviruses and viral antigens.
|
271 |
23162550
|
Previous murine studies have found that 4-1BB can participate in optimal priming of effector and memory CD8 T cells in response to several virus infections, and concordantly direct stimulation of 4-1BB with agonist reagents effectively boosts the CD8 T cell response against those viruses.
|
272 |
23162550
|
Here we show that agonist anti-4-1BB strongly enhanced the primary viral-specific effector CD8 T cell response during infection with live virulent VACV and attenuated VACV, and during immunization with VACV peptides given in IFA.
|
273 |
23162550
|
However, accumulation of memory CD8 T cells was enhanced only following infection with virulent VACV or with peptide vaccination, but not with attenuated VACV, correlating in part with more transient expression of 4-1BB on CD8 T cells with attenuated virus.
|
274 |
23162550
|
Our data therefore suggest that 4-1BB may be a promising candidate for targeting as an adjuvant for short-term enhancement of CD8 T cell responses with VACV vaccine strategies, but additional receptors may need to be engaged with 4-1BB to allow long-term CD8 T cell immunity with attenuated VACV vectors.

This effect was concomitant with greater induction of Ag-specific CD8+CTLs and their infiltration into the tumor sites, highlighting the importance of combined stimulation of TLR9 and 4.1BB for achieving tumor eradication.

The contextual role of TNFR family members in CD8(+) T-cell control of viral infections.
|
301 |
23947352
|
The role of specific TNF receptor (TNFR) family members in antiviral immunity depends on the stage of the immune response and can vary with the virus type and its virulence.
|
302 |
23947352
|
Here, we focus on five members of the TNFR family that are prominently expressed on CD8(+) T cells during viral infections, namely, 4-1BB (CD137), CD27, OX40 (CD134), GITR, and TNFR2. 4-1BB, CD27, OX40, and GITR have primarily prosurvival roles for CD8(+) T cells during viral infection, although under some circumstances 4-1BB, GITR, or CD27 signals can limit immunity.
|
303 |
23947352
|
Although TNFR2 can be costimulatory under some circumstances, its main role in CD8(+) T-cell responses during viral infection appears to be in contraction of the response.
|
304 |
23947352
|
Several TNF family ligands are being explored as adjuvants for viral vaccines, and agonistic antibodies to TNFR family members are being investigated for immunotherapy of chronic viral infection alone and in combination with checkpoint blockade.

Therefore, much effort has been made to generate agonistic Abs targeting members of the TNFR superfamily, such as OX40, 4-1BB, and GITR, expressed on effector T cells and Tregs, to reinvigorate T cell effector function and block Treg-suppressive function.
|
306 |
24014877
|
In this article, we describe the development of a panel of anti-human OX40 agonistic mouse mAbs that could promote effector CD4(+) and CD8(+) T cell proliferation, inhibit the induction of CD4(+) IL-10 -producing type 1 regulatory T cells, inhibit the expansion of ICOS(+)IL-10(+) Tregs, inhibit TGF-β-induced FOXP3 expression on naive CD4(+) T cells, and block natural Treg-suppressive function.

Here, we tested the hypothesis that aptamer-targeted siRNA inhibition of mTOR complex 1 (mTORC1) function in CD8(+) T cells can enhance their differentiation into memory T cells and potentiate antitumor immunity more effectively than the pharmacologic inhibitor rapamycin.
|
308 |
24292708
|
To specifically target activated cells, we conjugated an siRNA targeting the mTORC1 component raptor to an aptamer that binds 4-1BB, a costimulatory molecule that is expressed on CD8(+) T cells following TCR stimulation.
|
309 |
24292708
|
We found that systemic administration of the 4-1BB aptamer-raptor siRNA to mice downregulated mTORC1 activity in the majority of CD8(+) T cells, leading to the generation of a potent memory response that exhibited cytotoxic effector functions and enhanced vaccine-induced protective immunity in tumor-bearing mice.
|
310 |
24292708
|
In contrast, while treatment with the general mTORC1 inhibitor rapamycin also enhanced antigen-activated CD8(+) T cell persistence, the cytotoxic effector functions of the reactivated memory cells were reduced and the alloreactivity of DCs was diminished.

IL-15 cDNA and anti-4-1BB Abs might augment antitumor activity against established tumors.

|
IL-2 cDNA was slightly better than IL-15 cDNA as a pE7 adjuvant.
|
353 |
24391824
|
Co-delivery of pE7+IL-2 cDNA increased tumor cure rates from 7% to 27%, whereas co-delivery of pE7+IL-2 cDNA with anti-4-1BB Abs increased tumor cure rates from 27% to 67% and elicited long-term memory responses.
|
354 |
24391824
|
Moreover, the combined stimulation of IL-2 and 4-1BB receptors with rIL-2 and anti-4-1BB Abs resulted in enhanced production of IFN-γ from Ag-specific CD8+ T cells.
|
355 |
24391824
|
However, this effect was abolished by treatment with anti-IL-2 Abs and 4-1BB-Fc, suggesting that the observed effect was IL-2- and anti-4-1BB Ab-specific.

Vaccination with Leishmania mexicana LPG induces PD-1 in CD8⁺ and PD-L2 in macrophages thereby suppressing the immune response: a model to assess vaccine efficacy.
|
358 |
24462405
|
Since unsuccessful protection could be related to suppressed T cell responses, we analyzed the expression of inhibitory receptor PD-1 in CD8(+) and CD4(+) lymphocytes and it is ligand PD-L2 in macrophages of BALB/c mice immunized with various doses of Leishmania mexicana LPG and re-stimulated in vitro with different concentrations of LPG.
|
359 |
24462405
|
The expression of PD-1, PD-L2 and CD137 is modulated according to the amount of LPG used during immunization and in vitro re-stimulation.
|
360 |
24462405
|
Infection with 1×10(5) parasites increased the PD-1 expression in CD8(+) and diminished PD-L2 in macrophages.
|
361 |
24462405
|
We propose that the analysis of PD-1 and PD-L2 are useful tools to monitor the optimal dose for vaccination candidates.

This review focuses on a novel agonistic ligand, SA-4-1BBL, for 4-1BB costimulatory receptor as an adjuvant of choice because of its ability to: i) serve as a vehicle to deliver TAAs to dendritic cells (DCs) for antigen uptake and cross-presentation to CD8(+) T cells; ii) augment adaptive Th1 and innate immune responses; and iii) overcome various immune evasion mechanisms, cumulatively translating into therapeutic efficacy in preclinical tumor models.

Artificial antigen-presenting cells expressing CD80, CD70, and 4-1BB ligand efficiently expand functional T cells specific to tumor-associated antigens.
|
364 |
24713579
|
Here, in order to develop a novel aAPC system, we established K562 erythroleukemia cells expressing different combinations of co-stimulatory molecule ligands, CD80, CD70, and/or 4-1BB ligand (4-1BBL).
|
365 |
24713579
|
When nucleofected with in vitro-generated mRNA encoding a tumor-associated antigen, MART-1, the K562 cells expressing all of CD80, CD70, and 4-1BBL were the most efficient for expansion of functional T cells specific to an HLA-A2-restricted immunodominant epitope, MART-126-35.
|
366 |
24713579
|
In addition, only the K562 cells expressing all three of these co-stimulatory molecule ligands could clearly expand T cells specific to other less immunogenic antigen epitopes, gp100154-162 and Cyp1B1239-247, through transfection with in vitro generated gp100 and Cyp1B1 mRNA, respectively.
|
367 |
24713579
|
These results indicated that non-redundant and synergistic effects of co-stimulation via CD28/CD80, CD27/CD70, and 4-1BB/4-1BBL might be critical for eliciting efficient expansion of T cells; co-stimulation via the 4-1BB/4-1BBL interaction might expand antigen-specific T cells by preventing apoptotic cell death triggered by specific antigens in the presence of the CD28/CD80 and CD27/CD70 signaling.
|
368 |
24713579
|
Taken together, our findings suggested that this K562-based aAPC system expressing CD80, CD70, and 4-1BBL would be useful for efficiently stimulating functional antigen-specific T cells ex vivo, in particular when detailed information on the epitope specificities is unavailable.

We developed a retroviral CAR construct specific for the mouse fibroblast activation protein (FAP), comprising a single-chain Fv FAP [monoclonal antibody (mAb) 73.3] with the CD8α hinge and transmembrane regions, and the human CD3ζ and 4-1BB activation domains.
|
382 |
24778279
|
The antitumor effects could be augmented by multiple injections of the CAR T cells, by using CAR T cells with a deficiency in diacylglycerol kinase, or by combination with a vaccine.
|
383 |
24778279
|
In summary, inhibiting tumor growth by targeting tumor stroma with adoptively transferred CAR T cells directed to FAP can be safe and effective, suggesting that further clinical development of anti-human FAP-CAR is warranted.

|
385 |
24860188
|
In this study, we analyzed the CD8 T cell response elicited by two experimental vaccines comprising a peptide/protein Ag and an agonist that delivers a costimulatory signal via CD27 or 4-1BB.
|
386 |
24860188
|
CD27 agonists promoted increased expression of perforin and the generation of short-lived memory cells, whereas stimulation with 4-1BB agonists favored generation of stable memory.

387 |
24860188

388 |
24860188
|
Consistent with this conclusion, CD27 and 4-1BB-stimulated CD8 T cells expressed disparate amounts of IL-2, IFN-γ, CD25, CD71, and Gp49b as early as 3 d after in vivo activation.
|
389 |

|
447 |
25872647
|
CD3, CD4, CD8, CD56, FOXP3 and CEACAM6 expression in tumor tissues was determined by immunohistochemical staining.
|
448 |
25872647
|
Compared with the expression levels in the pIRES/SL3261 group, similar levels of CD3+, CD8+ and CD56+ expression were identified for the pIRES-CEACAM6/SL3261 group of rats.

Both Tim-3 and Tim-4 belong to the T-cell immunoglobulin and mucin domain (Tim) gene family, which plays a critical role in immunoregulation.
|
457 |
26211834
