To better understand the control of T helper (TH) 1-expressed genes, we compared and contrasted acetylation and expression for three key genes, IFNG, TBET, and IL18RAP and found them to be distinctly regulated.
|
| 21 |
15280353
|
The TBET and the IFNG genes, but not the IL18RAP gene, showed preferential acetylation of histones H3 and H4 during TH1 differentiation.
|
| 22 |
15280353
|
Histone H3 acetylation of IFNG and TBET genes occurred with different kinetics, however, and was distinctively regulated by cytokines.
|
| 23 |
15280353
|
Interleukin (IL)-12 and IL-18 enhanced the histone acetylation of the IFNG gene.
|
| 24 |
15280353
|
By contrast, histone acetylation of the TBET gene was markedly suppressed by IL-4, whereas IL-12 and IL-18 had only modest effects suggesting that histone acetylation during TH1 differentiation is a process that is regulated by various factors at multiple levels.
|
| 25 |
15280353
|
By treating Th2 cells with a histone deacetylase inhibitor, we restored histone acetylation of the IFNG and TBET genes, but it did not fully restore their expression in TH2 cells, again suggesting that histone acetylation explains one but not all the aspects of TH1-specific gene expression.

When linked to the murine Ifng gene (-3.4 to +5.6 kb) and transiently transfected into EL-4 cells, these elements clearly enhanced IFN-gamma expression in response to ionomycin and phorbol 12-myristate 13-acetate and weakly enhanced expression in response to T-bet.
|
| 51 |
15304658
|
A DNase I hypersensitive site and extragenic transcripts at IFNgCNS2 correlated positively with the capacity of primary T cell subsets to produce IFN-gamma.
|
| 52 |
15304658
|
Transcriptionally favorable histone modifications in the Ifng promoter, intronic regions, IFNgCNS2, and, although less pronounced, IFNgCNS1 increased as naïve T cells differentiated into IFN-gamma-producing effector CD8+ and T helper (TH) 1 T cells, but not into TH2 T cells.
|
| 53 |

|
Like IFN-gamma expression, these histone modifications were T-bet-dependent in CD4+ cells, but not CD8+ T cells.

Using conditional introduction of dominant-negative factors, we now show that T-bet and GATA-3 are far more critical in establishment than maintenance of IFN-gamma and IL-4 activity during Th1 and Th2 maturation, respectively.

|
T-bet plus Hlx can disrupt ifng silencing when introduced into developing Th2 cells, but they fail to perturb ifng silencing in mature Th2 cells.

In T cells, long-range histone acetylation depended on stimulation that drives both T helper (Th) 1 differentiation and active transcription, and it depended completely or partially on the presence of Stat4 or T-bet, respectively, two transcription factors that are required for Th1 lineage commitment.
|
| 63 |
16520391
|
T-bet regulates Th1 responses through essential effects on GATA-3 function rather than on IFNG gene acetylation and transcription.
|
| 64 |
16520391
|
T helper type 1 (Th1) development is facilitated by interrelated changes in key intracellular factors, particularly signal transducer and activator of transcription (STAT)4, T-bet, and GATA-3.
|
| 65 |
16520391
|
Here we show that CD4+ cells from T-bet-/- mice are skewed toward Th2 differentiation by high endogenous GATA-3 levels but exhibit virtually normal Th1 differentiation provided that GATA-3 levels are regulated at an early stage by anti-interleukin (IL)-4 blockade of IL-4 receptor (R) signaling.
|
| 66 |
16520391
|
In addition, under these conditions, Th1 cells from T-bet-/- mice manifest IFNG promotor accessibility as detected by histone acetylation and deoxyribonuclease I hypersensitivity.
|
| 67 |
16520391
|
In related studies, we show that the negative effect of GATA-3 on Th1 differentiation in T-bet-/- cells arises from its ability to suppress STAT4 levels, because if this is prevented by a STAT4-expressing retrovirus, normal Th1 differentiation is observed.
|
| 68 |
16520391
|
Finally, we show that retroviral T-bet expression in developing and established Th2 cells leads to down-regulation of GATA-3 levels.
|
| 69 |
16520391
|
These findings lead to a model of T cell differentiation that holds that naive T cells tend toward Th2 differentiation through induction of GATA-3 and subsequent down-regulation of STAT4/IL-12Rbeta2 chain unless GATA-3 levels or function is regulated by T-bet.
|
| 70 |
16520391

Thus, the principal function of T-bet in developing Th1 cells is to negatively regulate GATA-3 rather than to positively regulate the IFNG gene.

These findings lead to a model of T cell differentiation that holds that naive T cells tend toward Th2 differentiation through induction of GATA-3 and subsequent down-regulation of STAT4/IL-12Rbeta2 chain unless GATA-3 levels or function is regulated by T-bet.
|
| 118 |
16520391
|
Thus, the principal function of T-bet in developing Th1 cells is to negatively regulate GATA-3 rather than to positively regulate the IFNG gene.
|
| 119 |
16520391
|
T-bet regulates Th1 responses through essential effects on GATA-3 function rather than on IFNG gene acetylation and transcription.
|
| 120 |
16520391
|
T helper type 1 (Th1) development is facilitated by interrelated changes in key intracellular factors, particularly signal transducer and activator of transcription (STAT)4, T-bet, and GATA-3.
|
| 121 |
16520391
|
Here we show that CD4+ cells from T-bet-/- mice are skewed toward Th2 differentiation by high endogenous GATA-3 levels but exhibit virtually normal Th1 differentiation provided that GATA-3 levels are regulated at an early stage by anti-interleukin (IL)-4 blockade of IL-4 receptor (R) signaling.
|
| 122 |
16520391
|
In addition, under these conditions, Th1 cells from T-bet-/- mice manifest IFNG promotor accessibility as detected by histone acetylation and deoxyribonuclease I hypersensitivity.
|
| 123 |
16520391
|
In related studies, we show that the negative effect of GATA-3 on Th1 differentiation in T-bet-/- cells arises from its ability to suppress STAT4 levels, because if this is prevented by a STAT4-expressing retrovirus, normal Th1 differentiation is observed.
|
| 124 |
16520391
|
Finally, we show that retroviral T-bet expression in developing and established Th2 cells leads to down-regulation of GATA-3 levels.
|
| 125 |
16520391
|
These findings lead to a model of T cell differentiation that holds that naive T cells tend toward Th2 differentiation through induction of GATA-3 and subsequent down-regulation of STAT4/IL-12Rbeta2 chain unless GATA-3 levels or function is regulated by T-bet.

Transcription factors T-bet and Runx3 cooperate to activate Ifng and silence Il4 in T helper type 1 cells.
|
| 128 |
17195845
|
Here we show that the transcription factor Runx3 is induced in T helper type 1 (T(H)1) cells in a T-bet-dependent manner, and that both transcription factors T-bet and Runx3 are required for maximal production of interferon-gamma (IFN-gamma) and silencing of the gene encoding interleukin 4 (Il4) in T(H)1 cells.
|
| 129 |
17195845

T-bet does not repress Il4 in Runx3-deficient T(H)2 cells, but coexpression of Runx3 and T-bet induces potent repression in those cells.
|
| 130 |
17195845
|
Both T-bet and Runx3 bind to the Ifng promoter and the Il4 silencer, and deletion of the silencer decreases the sensitivity of Il4 to repression by either factor.
|
| 131 |
17195845
|
Our data indicate that cytokine gene expression in T(H)1 cells may be controlled by a feed-forward regulatory circuit in which T-bet induces Runx3 and then 'partners' with Runx3 to direct lineage-specific gene activation and silencing.

Differentiation of naive CD4+ T cells into T helper type 1 (Th1) effector cells requires both T cell receptor (TCR) signaling and cytokines such as interleukin-12 and interferon gamma (IFN-gamma).
|
| 154 |
18549798
|
Here, we report that a third cytokine signal, mediated by the Janus family tyrosine kinase 3 (Jak3) and signal transducer and activator of transcription 5 (STAT5) pathway, is also required for Th1 cell differentiation.
|
| 155 |
18549798
|
In the absence of Jak3-dependent signals, naive CD4+ T cells proliferate robustly but produce little IFN-gamma after Th1 cell polarization in vitro.
|
| 156 |
18549798
|
This defect is not due to reduced activation of STAT1 or STAT4 or to impaired upregulation of the transcription factor T-bet.
|
| 157 |
18549798
|
Instead, we find that T-bet binding to the Ifng promoter is greatly diminished in the absence of Jak3-dependent signals, correlating with a decrease in Ifng promoter accessibility and histone acetylation.

Ascaris-infected pigs had increased levels of liver mRNA for T-helper-2 (Th2)-associated cytokines, mast cell markers, and T regulatory (Treg) cells, while infected pigs given ATRA had higher IL4, IL13, CCL11, CCL26, CCL17, CCL22, and TPSB1 expression.
|
| 173 |
19332534

Gene expression for Th1-associated markers (IFNG, IL12B, and TBX21), the CXCR3 ligand (CXCL9), IL1B, and the putative Treg marker TNFRSF18 was also increased.
|

Recently, we reported a novel mechanism by which the T-box transcription factor T-bet interacts with JMJD3, an H3K27-demethylase, and Set7/9, an H3K4-methyltransferase (Genes Dev. 2008. 22: 2980-2993).
|

Therefore, studies examining the molecular mechanisms that account for the ability of T-bet to regulate Ifng and Cxcr3, prototypic CD4+ Th1 genes, have provided novel insight into essential regulatory events that occur at diverse developmental transitions.

A continuous T-bet expression is required to silence the interleukin-4-producing potential in T helper type 1 cells.
|

19689734
|
To develop into committed T helper type 1 (Th1) cells, naive CD4(+) T cells not only need to acquire the capacity to produce interferon-gamma (IFN-gamma), but they also need to gain the ability to silence their interleukin-4 (IL-4) -producing potential.
|
| 183 |
19689734

19689734

Although it has been shown that T-bet is a crucial factor in suppressing Il4 gene expression, it is unclear whether a continuous presence of T-bet is required to silence the Il4 gene in Th1 cells.

We found that the activation of T-bet during primary or secondary culture was sufficient to silence IL-4-producing potential.
|
| 241 |
19689734
|
On the other hand, the inactivation of T-bet after naïve CD4(+) T cells had differentiated into Th1 cells resulted in derepression of Il4 gene transcription.
|
| 242 |
19689734
|
Additionally, we found that T-bet is required to maintain Ifng expression.
|
| 243 |
19689734
|
Our data demonstrate that the continuous expression of T-bet is required for Th1 cells to silence their IL-4-producing potential.

Ikaros is a regulator of Il10 expression in CD4+ T cells.
|
| 245 |
19828627
|
Here we show that Ikaros, a zinc finger DNA-binding protein, plays an important role in the regulation of Il10 in murine CD4(+) T cells.
|
| 246 |
19828627
|
Upon initial stimulation of the TCR, T cells deficient in Ikaros express significantly lower levels of IL-10 compared with wild-type T cells.
|
| 247 |
19828627
|
In addition, under Th2 skewing conditions, which induce IL-10 production by wild-type T cells, Ikaros null T cells are unable to properly differentiate, producing only low levels of IL-10.
|
| 248 |
19828627
|
Expression of a dominant-negative isoform of Ikaros in wild-type Th2 cells represses IL-10 production but does not significantly alter expression levels of the genes encoding the transcription factors GATA-3 and T-bet.
|
| 249 |
19828627
|
Furthermore, expression of Ikaros in Ikaros null T cells restores expression of the Th2 cytokines IL-10 and IL-4 while reducing production of the Th1 cytokine, IFN-gamma.
|
| 250 |
19828627
|
Coexpression of Ikaros and GATA-3 further increases IL-10 production, showing that these two factors have an additive effect on activating Il10 expression.
|
| 251 |
19828627
|
Finally, we show that Ikaros binds to conserved regulatory regions of the Il10 gene locus in Th2 cells, supporting a direct role for Ikaros in Il10 expression.
|
| 252 |
19828627
|
Thus, we provide evidence for Ikaros as a regulator of Il10 and Ifng gene expression and suggest a role for Ikaros in directing lineage-specific cytokine gene activation and repression.

TNFalpha and TGF-beta1 influence IL-18-induced IFNgamma production through regulation of IL-18 receptor and T-bet expression.
|
| 254 |
19879772
|
IL-18 is a pro-inflammatory cytokine that drives dendritic cell maturation and mediates IFNgamma production.
|
| 255 |
19879772
|
In this study, we demonstrate that in the dendritic precursor-like cell line KG-1, IFNgamma production induced by IL-18 is potentiated (>5-fold) by TNFalpha and completely suppressed by TGF-beta1.
|
| 256 |
19879772
|
IL-18 stimulation rapidly activates different MAPK signalling pathways but only blocking of p38 activation alleviates IFNgamma production.
|
| 257 |
19879772
|
The mechanism through which TNFalpha enhances IL-18 induced IFNgamma production is by promoting IL-18 receptor alpha-chain expression which results in higher levels of p38 activation and induces expression of T-bet, a transcriptional regulator of the IFNG gene.
|
| 258 |
19879772
|
In contrast, TGF-beta1 rapidly suppresses IFNgamma production by limiting IL-18 receptor numbers at the cell surface and preventing induction of T-bet expression.
|

19879772
|
TGF-beta1 experience by cells leads to sustained long-term inactivation of TNFalpha/IL-18-mediated cell activation but not IL-18 induced p38 activation suggesting transcriptional silencing of the T-BET and/or IFNG promoter independent of MAPK signalling.

The transcription factor GATA3 actively represses RUNX3 protein-regulated production of interferon-gamma.
|
| 282 |
20399120
|
The transcription factor GATA3 is crucial for the differentiation of naive CD4(+) T cells into T helper 2 (Th2) cells.
|
| 283 |
20399120
|
Here, we show that deletion of Gata3 allowed the appearance of interferon-gamma (IFN-gamma)-producing cells in the absence of interleukin-12 (IL-12) and IFN-gamma.
|
| 284 |
20399120
|
Such IFN-gamma production was transcription factor T-bet independent.
|
| 285 |
20399120
|
Another T-box-containing transcription factor Eomes, but not T-bet, was induced both in GATA3-deficient CD4(+) T cells differentiated under Th2 cell conditions and in Th2 cells with enforced Runx3 expression, contributing to IFN-gamma production.
|
| 286 |
20399120
|
GATA3 overexpression blocked Runx3-mediated Eomes induction and IFN-gamma production, and GATA3 protein physically interacted with Runx3 protein.
|
| 287 |
20399120
|
Furthermore, we found that Runx3 directly bound to multiple regulatory elements of the Ifng gene and that blocking Runx3 function in either Th1 or GATA3-deficient "Th2" cells results in diminished IFN-gamma production by these cells.
|
| 288 |
20399120

Thus, the Runx3-mediated pathway, actively suppressed by GATA3, induces IFN-gamma production in a STAT4- and T-bet-independent manner.

|
Enhanced cell cycle and metabolic activity was restricted to the acute phase of the response, but at all stages, HCMV-specific CD8+ T cells expressed the Th1-associated transcription factors T-bet (TBX21) and eomesodermin (EOMES), in parallel with continuous expression of IFNG mRNA and IFN-γ-regulated genes.
|
| 306 |

Jmjd3 and UTX play a demethylase-independent role in chromatin remodeling to regulate T-box family member-dependent gene expression.
|
| 308 |
21095589
|
In this study, we show that the H3K27 demethylases, Jmjd3 and UTX, mediate a functional interaction between the lineage-defining T-box transcription factor family and a Brg1-containing SWI/SNF remodeling complex.
|
| 309 |
21095589
|
Importantly, Jmjd3 is required for the coprecipitation of Brg1 with the T-box factor, T-bet, and this interaction is necessary for Ifng remodeling in differentiated Th1 cells.

Protection against diabetes was accompanied by histone hyperacetylation in pancreas and spleen, enhanced frequency of CD4(+) CD62L(+) cells in the spleen, reduction in cellular infiltration of islets, restoration of normoglycemia and glucose-induced insulin release by beta cells.
|
| 311 |
21321581
|
Activation of splenic T lymphocytes derived from protected mice in vitro with pharmacological agents that bypass the antigen receptor or immobilized anti-CD3 antibody resulted in enhanced expression of Ifng mRNA and protein without altering the expression of Il4, Il17, Il18, Inos and Tnfa genes nor the secretion of IL-2, IL-4, IL-17 and TNF-α proteins.
|
| 312 |
21321581
|
Consistently, expression of the transcription factor involved in Ifng transcription, Tbet/Tbx21 but not Gata3 and Rorgt, respectively, required for the transcription of Il4 and Il17, was upregulated in activated splenocytes of protected mice.

Rapamycin-sensitive signals control TCR/CD28-driven Ifng, Il4 and Foxp3 transcription and promoter region methylation.
|
| 314 |
21480212
|
Here, we report that both mTOR complex 1 and mTOR complex 2 are readily activated following TCR/CD28 engagement and are critical for early expression of Ifng, Il4 and Foxp3, and for effector T cell differentiation in the absence of polarizing cytokines.
|
| 315 |
21480212
|
While inhibition of mTOR complex 1 and cell division were evident at low doses of RAPA, inhibition of mTOR complex 2, Ifng, Il4 and Foxp3 expression, and T-cell polarization required higher doses and more prolonged treatments.
|
| 316 |
21480212
|
We found that while T-bet and GATA3 were readily induced following TCR/CD28 engagement, administration of RAPA delayed their expression, and interfered with the loss of DNA methylation within Ifng and Il4 promoter regions.

|
| 320 |
21518797
|
Consistent with this, we identified two T-bet DNA-binding elements in the Socs1 promoter that are functionally used to down-regulate transcription in primary Th1 cells.
|
| 321 |
21518797
|
Furthermore, T-bet functionally recruits Bcl-6 to the Ifng locus in late stages of Th1 differentiation to repress its activity, possibly to prevent the overproduction of IFN-γ, which could result in autoimmunity.

T-bet orchestrates the differentiation of mature peripheral T-cells into interferon-γ (IFN-γ) and tumor necrosis factor-α producing CD4+ T-helper type I (Th1) and CD8+ T cytotoxic cells that are necessary for antiviral responses.
|
| 343 |
21983879

When IL-12 is produced by antigen-presenting cells, T-bet expression is induced, causing direct stimulation of ifng gene transcription while simultaneously acting as a transcriptional repressor of the IL4 gene, which then leads to Th1 dominance and T-helper type 2 differentiation blockade.

We used a gene panel of regulatory/inflammatory molecules (FOXP3, GATA3, IL10, TGFB1, TGFBR1/ TBX21, TNF and IFNG) to investigate the gene expression profile in peripheral blood mononuclear cells of renal-transplanted individuals experiencing OT compared to transplanted individuals not displaying OT and healthy individuals (HI).

Twist1 regulates Ifng expression in Th1 cells by interfering with Runx3 function.

A transcription factor network that includes STAT4, T-bet, and Runx3 promotes the differentiation of Th1 cells and inflammatory immune responses.
|
| 355 |

In this study we show that the negative regulatory factor Twist1 decreases expression of T-bet, Runx3, and IL-12Rβ2 as it inhibits IFN-γ production.
|
| 356 |
22685315
|
Ectopic expression of Runx3, but not T-bet or IL-12Rβ2, compensates for the effects of Twist1 on IFN-γ production, and Twist1 regulation of Ifng depends on complex formation with Runx3.
|
| 357 |

Twist1 decreases Runx3 and T-bet binding at the Ifng locus, and it decreases chromatin looping within the Ifng locus.

A transcription factor network that includes STAT4, T-bet, and Runx3 promotes the differentiation of Th1 cells and inflammatory immune responses.
|
| 367 |
22685315
|
In this study we show that the negative regulatory factor Twist1 decreases expression of T-bet, Runx3, and IL-12Rβ2 as it inhibits IFN-γ production.
|
| 368 |
22685315
|
Ectopic expression of Runx3, but not T-bet or IL-12Rβ2, compensates for the effects of Twist1 on IFN-γ production, and Twist1 regulation of Ifng depends on complex formation with Runx3.
|
| 369 |
22685315
|
Twist1 decreases Runx3 and T-bet binding at the Ifng locus, and it decreases chromatin looping within the Ifng locus.

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.
|
| 378 |
22685317
|
When Roquin is mutated (Roquin(san)), effector CD8(+) T cells accumulate in a cell-autonomous manner, most prominently as SLEC-like effectors.
|
| 379 |
22685317
|
Excessive IFN-γ promotes the accumulation of SLEC-like cells, increases their T-bet expression, and enhances their granzyme B production in vivo.
|
| 380 |
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.

In this study, we show that transcription of both mouse and human TMEVPG1 genes is Th1 selective and dependent on Stat4 and T-bet, transcription factors that drive the Th1 differentiation program.
|
| 382 |
22851706
|
Ifng expression is partially restored in Stat4-/-Tbx21-/- cells through coexpression of T-bet and Tmevpg1, and Tmevpg1 expression contributes to, but alone is not sufficient to, drive Th1-dependent Ifng expression.

The infected mice displayed a significant up-regulation in the expression of chemokines (Cxcl1, Cxcl2 and Ccl2), numerous pro-inflammatory cytokines (Ifng, Il1b, Il6, and Il17f), as well as Il22 and a number of anti-microbial peptides (Defa1, Defa28, Defb1, Slpi and Reg3g) at the site(s) of infection.
|
| 387 |
23668260
|
However, CD4 T cells of the untreated and C. difficile-infected mice expressed similar levels of CD69 and CD25.
|
| 388 |
23668260
|
Neither tissue had up-regulated levels of Tbx21, Gata3 or Rorc.
|
| 389 |
23668260
|
They also displayed significantly higher phosphorylation of AKT and signal transducer and activator of transcription 3 (STAT3), an indication of pro-survival signalling.
|
| 390 |
23668260
|
These data underscore the local, innate, pro-inflammatory nature of the response to C. difficile and highlight eIF2α phosphorylation and the interleukin-22-pSTAT3-RegIIIγ axis as two of the pathways that could be used to contain and counteract the damage inflicted on the intestinal epithelium.

STAT4 and T-bet are required for the plasticity of IFN-γ expression across Th2 ontogeny and influence changes in Ifng promoter DNA methylation.
|
| 392 |
23761633
|
CD4(+) T cells developing toward a Th2 fate express IL-4, IL-5, and IL-13 while inhibiting production of cytokines associated with other Th types, such as the Th1 cytokine IFN- γ.
|
| 393 |
23761633
|
We now show that this flexibility ("plasticity") of cytokine expression is preceded by a loss of the repressive DNA methylation of the Ifng promoter acquired during Th2 polarization yet requires STAT4 along with T-box expressed in T cells.
|
| 394 |
23761633
|
Surprisingly, loss of either STAT4 or T-box expressed in T cells increased Ifng promoter CpG methylation in both effector and memory Th2 cells.

In biofunction assays, recombinant gCCL4 was found to induce chemotactic activity in the peripheral blood leukocytes of groupers and up-regulate the gene expressions of grouper TNFA1 (TNF-α1), TNFA2 (TNF-α2), IFNG (IFN-γ), MX, TBX21 (T-bet), CD8 (α and β chain).

SerpinB1 regulates homeostatic expansion of IL-17+ γδ and CD4+ Th17 cells.
|
| 405 |
24249741
|
Here, we show that IL-17A(+) γδ and CD4(+) Th17 cells are already expanded in the lungs of serpinb1a(-/-) mice at steady-state.
|
| 406 |
24249741
|
Both γδ and αβ(+) CD4(+) CCR6(+) T cells isolated from the lungs of naive serpinb1a(-/-) mice displayed a skewed transcriptional profile relative to WT cells, including increased Th17 signature transcripts [Il17a, l17f, and Rorc (RORγt)] and decreased Th1 signature transcripts [Ifng, Cxcr3, and Tbx21 (T-bet)] in γδ T cells.
|
| 407 |
24249741
|
In addition to the lung, IL-17A(+) γδ and CD4(+) Th17 cells were increased in the spleen of naive serpinb1a(-/-) mice, despite normal αβ and γδ T cell development in the thymus.
|
| 408 |
24249741
|
Within the γδ T cell compartment, loss of serpinb1a prompted selective expansion of Vγ4(+) and Vγ6/Vδ1(+) cells, which also displayed elevated expression of the proliferating cell nuclear antigen, Ki-67, and IL-17A.
|
| 409 |
24249741
|
Given that serpinb1a is preferentially expressed in WT IL-17A(+) γδ and CD4(+) Th17 cell subsets vis-à-vis other T cell lineages, our findings reveal a novel function of serpinB1 in limiting untoward expansion of lymphocytes with a Th17 phenotype.

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(-)).
|
| 411 |
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(-)).
|
| 412 |
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(+)).
|
| 413 |
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.
