Inoculation with a white matter emulsion combined with FREUND'S ADJUVANT, myelin basic protein, or purified central myelin triggers a T cell-mediated immune response directed towards central myelin. The pathologic features are similar to MULTIPLE SCLEROSIS, including perivascular and periventricular foci of inflammation and demyelination. Subpial demyelination underlying meningeal infiltrations also occurs, which is also a feature of ENCEPHALOMYELITIS, ACUTE DISSEMINATED. Passive immunization with T-cells from an afflicted animal to a normal animal also induces this condition. (From Immunol Res 1998;17(1-2):217-27; Raine CS, Textbook of Neuropathology, 2nd ed, p604-5)

Prevention of collagen-induced arthritis by gene delivery of soluble p75 tumour necrosis factor receptor. (1/5809)

Collagen type II-induced arthritis (CIA) in DBA/1 mice can be passively transferred to SCID mice with spleen B- and T-lymphocytes. In the present study, we show that infection ex vivo of splenocytes from arthritic DBA/1 mice with a retroviral vector, containing cDNA for the soluble form of human p75 receptor of tumour necrosis factor (TNF-R) before transfer, prevents the development of arthritis, bone erosion and joint inflammation in the SCID recipients. Assessment of IgG subclass levels and studies of synovial histology suggest that down-regulating the effector functions of T helper-type 1 (Th1) cells may, at least in part, explain the inhibition of arthritis in the SCID recipients. In contrast, the transfer of splenocytes infected with mouse TNF-alpha gene construct resulted in exacerbated arthritis and enhancement of IgG2a antibody levels. Intriguingly, infection of splenocytes from arthritic DBA/1 mice with a construct for mouse IL-10 had no modulating effect on the transfer of arthritis. The data suggest that manipulation of the immune system with cytokines, or cytokine inhibitors using gene transfer protocols can be an effective approach to ameliorate arthritis.  (+info)

Enhanced Th1 activity and development of chronic enterocolitis in mice devoid of Stat3 in macrophages and neutrophils. (2/5809)

We have generated mice with a cell type-specific disruption of the Stat3 gene in macrophages and neutrophils. The mutant mice are highly susceptible to endotoxin shock with increased production of inflammatory cytokines such as TNF alpha, IL-1, IFN gamma, and IL-6. Endotoxin-induced production of inflammatory cytokines is augmented because the suppressive effects of IL-10 on inflammatory cytokine production from macrophages and neutrophils are completely abolished. The mice show a polarized immune response toward the Th1 type and develop chronic enterocolitis with age. Taken together, Stat3 plays a critical role in deactivation of macrophages and neutrophils mainly exerted by IL-10.  (+info)

Interleukin-18 binding protein: a novel modulator of the Th1 cytokine response. (3/5809)

An interleukin-18 binding protein (IL-18BP) was purified from urine by chromatography on IL-18 beads, sequenced, cloned, and expressed in COS7 cells. IL-18BP abolished IL-18 induction of interferon-gamma (IFNgamma), IL-8, and activation of NF-kappaB in vitro. Administration of IL-18BP to mice abrogated circulating IFNgamma following LPS. Thus, IL-18BP functions as an inhibitor of the early Th1 cytokine response. IL-18BP is constitutively expressed in the spleen, belongs to the immunoglobulin superfamily, and has limited homology to the IL-1 type II receptor. Its gene was localized on human chromosome 11q13, and no exon coding for a transmembrane domain was found in an 8.3 kb genomic sequence. Several Poxviruses encode putative proteins highly homologous to IL-18BP, suggesting that viral products may attenuate IL-18 and interfere with the cytotoxic T cell response.  (+info)

Reciprocal control of T helper cell and dendritic cell differentiation. (4/5809)

It is not known whether subsets of dendritic cells provide different cytokine microenvironments that determine the differentiation of either type-1 T helper (TH1) or TH2 cells. Human monocyte (pDC1)-derived dendritic cells (DC1) were found to induce TH1 differentiation, whereas dendritic cells (DC2) derived from CD4+CD3-CD11c- plasmacytoid cells (pDC2) induced TH2 differentiation by use of a mechanism unaffected by interleukin-4 (IL-4) or IL-12. The TH2 cytokine IL-4 enhanced DC1 maturation and killed pDC2, an effect potentiated by IL-10 but blocked by CD40 ligand and interferon-gamma. Thus, a negative feedback loop from the mature T helper cells may selectively inhibit prolonged TH1 or TH2 responses by regulating survival of the appropriate dendritic cell subset.  (+info)

Enhanced Th1 and dampened Th2 responses synergize to inhibit acute granulomatous and fibrotic responses in murine schistosomiasis mansoni. (5/5809)

In murine schistosomiasis mansoni, CD4(+) Th1 and Th2 cells participate in the ovum-induced granulomatous inflammation. Previous studies showed that the interleukin-12 (IL-12)-induced Th1 response strongly suppressed the Th2-cell-mediated pulmonary granuloma development in naive or primed mice. However, liver granulomas were only moderately suppressed in egg-vaccinated, recombinant IL-12 (rIL-12)-treated infected mice. The present study shows that repeated rIL-12 injections given during early granuloma development at 5 to 7 weeks after infection prolonged the Th1 phase and resulted in gamma interferon-mediated suppression of liver granulomas. The timing is crucial: if given at 6 to 8 weeks, during the Th2-dominated phase of florid granuloma growth, the treatment is ineffective. Daily injections of rIL-12 given between 5 and 7.5 weeks during the period of granuloma growth achieved a somewhat-stronger diminution in granuloma growth with less deposition of collagen but caused 60% mortality and liver pathology. In contrast, combined treatment with rIL-12 and anti-IL-4-anti-IL-10 monoclonal antibody (MAb) injections given during the Th2 phase strongly inhibited liver granuloma growth without mortality. The diminished inflammatory response was accompanied by less deposition of collagen in the liver. Moreover, neutralization of endogenous IL-12 by anti-IL-12 MAbs effectively decreased the early Th1 phase (between 5 and 6 weeks after infection) but not the developing Th2 phase (5 to 7 weeks) of granuloma development. These studies indicate that the granulomatous response in infected mice can be manipulated by utilizing the Th1-Th2-subset antagonism with potential salutary results in the amelioration of fibrous pathology.  (+info)

Interleukin-10 inhibits expression of both interferon alpha- and interferon gamma- induced genes by suppressing tyrosine phosphorylation of STAT1. (6/5809)

Interleukin-10 (IL-10) helps maintain polarized T-helper cells in a T-helper lymphocyte 2 (Th2) phenotype. Part of this process involves the prevention of the development of Th1 cells, which are a primary source of interferon gamma (IFNgamma), a potent activator of monocytes and an inhibitor of Th2 proliferation. Because monocytes and macrophages are important mediators of Th1-type responses, such as delayed-type hypersensitivity, we sought to determine if IL-10 could directly mediate inhibition of IFNgamma- and IFNalpha-induced gene expression in these cells. Highly purified monocytes were incubated with IL-10 for 60 to 90 minutes before the addition of IFNgamma or IFNalpha. IL-10 preincubation resulted in the inhibition of gene expression for several IFN-induced genes, such as IP-10, ISG54, and intercellular adhesion molecule-1. The reduction in gene expression resulted from the ability of IL-10 to suppress IFN-induced assembly of signal transducer and activator of transcription (STAT) factors to specific promoter motifs on IFNalpha- and IFNgamma-inducible genes. This was accomplished by preventing the IFN-induced tyrosine phosphorylation of STAT1, a component of both IFNalpha- and IFNgamma-induced DNA binding complexes. Therefore, IL-10 can directly inhibit STAT-dependent early response gene expression induced by both IFNalpha and IFNgamma in monocytes by suppressing the tyrosine phosphorylation of STAT1. This may occur through the ability of IL-10 to induce expression of the gene, suppressor of cytokine signaling 3 (SOCS3).  (+info)

Interleukin-12 induces expression of interferon regulatory factor-1 via signal transducer and activator of transcription-4 in human T helper type 1 cells. (7/5809)

IRF-1-deficient mice show a striking defect in the development of T helper 1 (Th1) cells. In the present report, we investigate the expression of IRF-1 during differentiation of human T helper cells. No significant differences of IRF-1 mRNA expression were found in established Th1 and Th2 cells; however, interleukin 12 (IL-12) induced a strong up-regulation of IRF-1 transcripts in Th1 but not in Th2 cells. We demonstrate that IL-12-induced up-regulation of IRF-1 is mediated by signal transducer and activator of transcription-4, which binds to the interferon (IFN)-gamma-activated sequence present in the promoter of the IRF-1 gene. Strong IL-12-dependent activation of a reporter gene construct containing the IRF-1 IFN-gamma-activated sequence element provides further evidence for the key role of signal transducer and activator of transcription-4 in the IL-12-induced up-regulation of IRF-1 transcripts in T cells. IRF-1 expression was strongly induced after stimulation of naive CD4(+) T cells via the T cell receptor, irrespective of the cytokines present at priming, indicating that this transcription factor does not play a major role in initiating a Th1-specific transcriptional cascade in differentiating helper T cells. However, our finding that IRF-1 is a target gene of IL-12 suggests that some of the IL-12-induced effector functions of Th1 cells may be mediated by IRF-1.  (+info)

Cytokine network and resident renal cells in glomerular diseases. (8/5809)

This review has highlighted the cytokine network which is involved in renal damage from an initial, even transient, stage to extensive glomerular and tubulointerstitial sclerosis. Studies of a variety of different proliferative glomerulonephritides have documented the prominent role of macrophages in infiltrating mesangium, subendothelial area and crescentic formation. Thus, they stimulate crescent glomerular cells to produce other cytokines and growth factors. The identification of other mediators, released by the monocytes in the interstitium, exemplifies the important role of these cells in progressive interstitial scarring through the release of fibrogenic cytokines. In addition, renal tubular cells have been found to produce a vast array of cytokines and growth factors which participate in the generation of renal interstitial scarring.  (+info)

CD4+ T cells play an important role in the initiation of an immune response by providing help to other cells. Among the helper T subsets, interferon-γ (IFN-γ)-secreting T helper 1 (Th1) and IL-17-secreting T helper 17 (Th17) cells are indispensable for clearance of intracellular as well as extracellular pathogens. However, Th1 and Th17 cells are also associated with pathogenesis and contribute to the progression of multiple inflammatory conditions and autoimmune diseases. In the current study, we found that BJ-1108, a 6-aminopyridin-3-ol analogue, significantly inhibited Th1 and Th17 differentiation in vitro in a concentration-dependent manner, with no effect on proliferation or apoptosis of activated T cells. Moreover, BJ-1108 inhibited differentiation of Th1 and Th17 cells in ovalbumin (OVA)-specific OT II mice. A complete Freunds adjuvant (CFA)/OVA-induced inflammatory model revealed that BJ-1108 can reduce generation of proinflammatory Th1 and Th17 cells. Furthermore, in vivo studies showed that
The liver is the major site of clearance and degradation of foreign antigens from the portal circulation. Despite the presence of hepatic accessory cells, antibody responses to orally administered antigens are uncommon. To ascertain if hepatic accessory cells are incapable of stimulating specific subsets of T lymphocytes, freshly isolated hepatic nonparenchymal and splenic cells were cultured with a panel of antigen-specific, H-2-restricted Th1 and Th2 HTL clones. Whereas spleen cells stimulated the proliferation of both Th1 and Th2 clones, hepatic nonparenchymal cells (NPC) stimulated the proliferation of only Th1 and not Th2 clones. Adding rIL-1, rIL-6, and rIL-7, alone or in combination, to the cultures did not result in proliferation of the Th2 clones. Despite the absence of Th2 proliferation, NPC were able to stimulate the secretion of IL-3 and IL-4 by Th2 clones in the presence of antigen. Moreover, adding hepatic NPC did not inhibit spleen cells from stimulating Th2 clones in the presence ...
In this study we demonstrate that autoimmunity to retina can be either Th17 or Th1 driven. The IL-23-IL-17 pathway plays an important role in EAU, and intensity of IL-17 response systemically and locally correlates with disease severity in mice immunized with IRBP/CFA. However, the role of the Th17 effector is redundant with Th1, and each effector phenotype by itself is sufficient to induce pathology in the absence of the reciprocal hallmark cytokine. In contrast, the role of IL-23 in disease pathogenesis is essential and nonredundant, raising the possibility that the requirement for IL-23 in EAU transcends its role in promoting the Th17 effector response. The conditions that drive to a Th17-dominated, or a Th1-dominated, pathogenic effector response appear to include the context in which the first encounter with auto-Ag occurs.. Until recently, the role of IL-12 in promoting the generation of IFN-γ-producing Th1 effector cells was considered the main pathogenic pathway in autoimmune diseases ...
In this work, we investigated the role of IL-6 in the lineage decision of antigen-specific CD4+ T cells during an autoimmune response in vivo. We found that unresponsiveness to IL-6 restricted to T cells is sufficient to mount a massive T-reg response in vivo that prevents the induction of Th1 and Th17 effector cells and results in complete resistance to EAE. However, the failure to induce Th17 cells in gp130−/− mice is not caused by an intrinsic inability of gp130−/− CD4+ T cells to become Th17 cells because the combination of TGF-β plus IL-21 induced the expression of IL-17 in naive gp130−/− CD4+ T cells. Also, T-reg-depleted gp130−/− mice were able to mount a pathogenic Th17 response upon immunization with MOG/CFA in vivo. Thus, alternative pathways exist to induce Th17 cells in the absence of IL-6 signaling. However, IL-6 has a dual role because it also suppresses the induction of Foxp3. Here, IL-6/IL-6R signaling in CD4+ T cells constitutes a dominant pathway because in the ...
TH17 cells (interleukin-17 (IL-17)-producing helper T cells) are highly proinflammatory cells that are critical for clearing extracellular pathogens and for inducing multiple autoimmune diseases. IL-23 has a critical role in stabilizing and reinforcing the TH17 phenotype by increasing expression of IL-23 receptor (IL-23R) and endowing TH17 cells with pathogenic effector functions. However, the precise molecular mechanism by which IL-23 sustains the TH17 response and induces pathogenic effector functions has not been elucidated. Here we used transcriptional profiling of developing TH17 cells to construct a model of their signalling network and nominate major nodes that regulate TH17 development. We identified serum glucocorticoid kinase 1 (SGK1), a serine/threonine kinase, as an essential node downstream of IL-23 signalling. SGK1 is critical for regulating IL-23R expression and stabilizing the TH17 cell phenotype by deactivation of mouse Foxo1, a direct repressor of IL-23R expression. SGK1 has ...

Control of inflammation critically depends on the twist genes. Genetic haploinsufficiency of both twist1 and twist2 results in fatal systemic inflammatory immunopathology in mice, which die before day 14 (4). In this study, we show that twist1 is expressed in Th1 EM cells. Its expression is induced by IL-12 via STAT4 and TCR signaling, activating NFAT and NF-κB. Expression of twist1 follows TCR stimulation transiently and increases upon repeated stimulation. Thus, imprinting for enhanced twist1 expression is a hallmark of repeatedly restimulated Th1 memory cells.. The proximal promoter of twist1 contains phylogenetically conserved binding sites for NFAT, NF-κB, and STAT proteins. Both NFAT and NF-κB have to bind to the promoter of twist1 in Th cells to induce expression, i.e., twist1 is expressed only by activated Th cells. In the initial activation of naive Th cells, NFAT and NF-κB cannot induce transcription of twist1 on their own, but require concerted binding of activated STAT4 to the ...

In this study, we provide definitive evidence that the main function of miR-21 is to regulate the IL-12/IFN-γ axis in multiple models of immune hypersensitivity and that the role of miR-21 in this process is nonredundant. Notably, we provide empiric evidence that this is a major and functionally relevant role for miR-21. To the best of our knowledge, this is the first study demonstrating the role of miR-21 in regulating Th1 versus Th2 responses in vivo. Prior studies concerning miR-21 have primarily focused on its role in tumorigenesis and tissue remodeling (21, 30-33), so the finding that miR-21 dominantly regulates the IL-12/IFN-γ axis in vivo is unexpected. Prior work concerning the regulation of IL-12/IFN-γ has all focused on their molecular regulation by cytokines and transcription factors (7, 34), so our finding that this critical step in adaptive immunity is regulated by a specific miR presents a new paradigm with broad and deep implications.. We have previously shown that miR-21 is ...

Acute myeloid leukemia (AML) is a hematological tumor in which progress T helper (Th) subsets including Th22, Th17, and Th1 cells play a pivotal role. However, the role of T helper (Th) subsets in the immune pathogenesis of AML remains unclear. Here, we investigated frequencies of Th22, Th17, pure Th17, and Th1 cells in the peripheral blood (PB) of AML patients. We demonstrated that Th22, Th17, and pure Th17 in newly-diagnosed (ND) and non-complete remission (Non-CR) AML patients and plasma IL-22 in ND AML patients were significantly increased. Retinoid-related orphan receptor C (RORC) expression was significantly elevated in CR and Non-CR AML patients. However, Th1 in ND AML patients and IL-17 in ND, Non-CR or CR AML patients was significantly decreased compared with controls. Moreover, Th22 and IL-22 showed positive correlation with pure Th17, but Th22 showed negative correlation with Th1 in ND AML patients. RORC showed positive correlation with Th22 and approximately positive correlation with pure

In this study we have demonstrated that an OX40L-dependent mechanism is functional in PDC-mediated Th responses. In dictating the quality of Th cell responses, OX40L selectively induced Th2-type immune responses by promoting CD4+ T cells to secrete IL-4, IL-5, and IL-13 (Figs. 4⇑ and 5⇑) (14, 15, 16, 17, 18, 19, 20, 21, 27). Meanwhile, IFN-αβ not only induced IFN-γ production, but also inhibited Th2 cytokine production (36, 37), resulting in the preferential development of Th1-type immunity. We have also demonstrated that IL-3-treated PDCs, which are widely noted as Th2-inducible DCs (so-called DC2) (4), expressed OX40L (Fig. 3⇑), but barely produced any IFN-α (Fig. 2⇑B). Indeed, the costimulatory function of OX40L on 3d-IL-3-PDCs was responsible for the preferential priming of Th2 cells (Figs. 4⇑ and 5⇑). However, even the immature 1d-IL-3-PDCs, which partially and weakly expressed OX40L, could induce Th2 cells to some extent, and the addition of anti-OX40L Ab could not ...

Hi Immunonetters, The discrimination between Th1 and Th2 phenotypes was established from data about T cell clones derived from mice. With this background, it is possible to characterize individual cells. Although, if you look in vivo, the image you will get is quite more confuse. Moreover, the studies made in human suggest strongly that the simple scheme of Th1/Th2 is rather difficult to apply. On the other hand, if you focus your attention on global response and not on single cells, I think that it is possible to characterize either Th1 like response or Th2 like response. In each case the cytokines and the effectors implied in hte response will be different, altho!ugh with some overlapping. I think that in the scope of therapy, the global evaluation of Th1/Th2 balance should lead to better results than the fine description of individual clones. I think that is one of the reason why immunologist look only to specific cytokines like IL4,IL10,IL2 and IFNg. The detection of these cytokines is ...
The exact function of Th17 cells are though to be involved in autoimmune and tumor cell response1, so how are these Th17 produce? After a naïve Th cell is activated by signals 1, 2, and 3, it can choose to illicit one of three different responses based upon the cytokines present within its surrounding environment: Th1, Th2, or Th171. (If youre interested in learning more about Th1 or Th2 responses check out this link) In order to become a Th17 cell, the activated Th cell must be exposed to IL-6 and TGFβ to differentiate1. After differentiation is complete, the now Th17 cell releases its own cytokines, IL-17 and IL-6, to cause an immune response1. For the visual learners, heres an image that depicts this as well: ...
This article was originally written as a guest post for The Paleo Mom. In my last article I explained the basic roles of Th1 and Th2 in the immune system as well as how they can be imbalanced in those suffering from autoimmune disease. In this article, I am going to cover the nutritional compounds that can shift the balance between Th1 and Th2, as well as those that are known to modulate them.. How do I tell if my immune system is imbalanced?. A Th1/Th2 Cytokine blood panel is the best way for a person to find out which side of their immune system is dominant. Alternatively, a person can also participate in a supplement challenge, where they take a nutritional supplement that stimulates Th1 for a few days and then switch to a supplement that stimulates Th2 for a few days, while noting the effect this has on their symptoms. (Update: there are some newer tests that can establish Th 1 versus Th2 dominance, discussed in the comments on this post). What is the protocol for balancing the immune ...

Differentiation of naïve CD4+ T cells into the T helper type 1 (TH1) phenotype requires signaling by interleukin (IL)-12 through the IL-12 receptor β2 chain, and activation of the signal transducer and activator of transcription (STAT) 4. On the other hand, induction of the TH2 phenotype from naïve CD4+ T cells requires IL-4 binding of the functional IL-4 receptor and activation of STAT6. A concomitant reduction of IL-12Rβ2 is also observed. When naïve CD4+ T cells are treated simultaneously with both IL-4 and IL-12, the IL-4 effects predominate and TH2 cells develop. Thus, it has been hypothesized that IL-4-dependent decreases in IL-12Rβ2 expression prevent IL-12 signals, and this allows for differentiation into the TH2 phenotype. However, it is not known what effect constitutive expression of the IL-12Rβ2 chain has on the development of TH2 cells. Nishikomori et al. found that IL-12Rβ2 transgenic CD4+ T cells differentiated into TH2 cells in the presence of IL-4, or IL-4 and IL-12. ...

CD26high T cells derived from the peripheral blood of healthy individuals were polyfunctional, cosecreting elevated IL-17A and IFN-γ, while classic TH1, TH2, or TH17 cells lacked this dynamic profile. Moreover, CD26high T cells had epigenetic and molecular properties distinguishing them from TH17 or TH1 cells. Of clinical importance, CD26high T cells persisted and ablated mesothelioma in mice when ex vivo engineered with CAR, while TH17 cell therapies transiently regressed tumors, and bulk CD4+, TH1, or TH2 subsets were largely ineffective.. As TH17 cells express the highest CD26 relative to other subsets, we anticipated that CD26 or IL-17 may be driving antitumor properties in TH17/CD26high T cell therapies. Unexpectedly, neither of these factors appeared critical to delay tumor growth. CRISPR-Cas9-mediated knockout of CD26 in TH17 cells delayed the onset of tumor regression but ultimately did not affect the overall antitumor response in mice. In addition, CAR TH17 or CD26high T cells ...
Interleukin (IL)-17-producing helper T (Th17) cells serve as a subset of CD4+ T cells involved in epithelial cell- and neutrophil mediated immune responses against extracellular microbes and in the pathogenesis of autoimmune diseases. In vivo, Th17 differentiation requires antigen presentation and co-stimulation, and activation of antigen presenting-cells (APCs) to produce TGF-beta, IL-6, IL-1, IL-23 and IL-21. This initial activation results in the activation and up-regulation of STAT3, ROR(gamma)t and other transcriptional factors in CD4+ T cells, which bind to the promoter regions of the IL-17, IL-21 and IL-22 genes and induce IL-17, IL-21 and IL-22. In contrast, the differentiation of Th17 cells and their IL-17 expression are negatively regulated by IL-2, Th2 cytokine IL-4, IL-27 and Th1 cytokine IFN-gamma through STAT5, STAT6 and STAT1 activation, respectively. Retinoid acid and the combination of IL-2 and TGF-beta upregulate Foxp3, which also downregulates cytokines like IL-17 and IL-21. ...

It is well accepted that Th1 cells play a central role for protection against TB [41]. Therefore, animals that are deficient in IFN-γ, IFN-γ receptor, Stat-4, T-bet, or IL-12 exhibit increased susceptibility to M. tb infection [25], [42], [43]. BCG induces a robust Th1 response, but this does not appear to be sufficient for optimal protection against challenge with virulent M. tb [44]. Abundant Th1 cell responses have been found in TB patients as well as M. tb infected animals [45], [46]. Thus, Th1 cells alone are not sufficient for protection against TB. Therefore, in addition to Th1 cell responses, a vaccine needs to induce additional Th cell response(s) to provide optimal protection against TB. Recently, it has been shown that Th17 cells play an important role in the secondary immune response against TB [16]. However, Th17 cells do not appear to participate in the primary immune response against TB [17]. Our findings clearly demonstrated that BCG and H37RvΔRD1 are unable to induce Th17 ...

T-lymphocytes play a central role in the regulation of immune responses through the secretion of different sets of cytokines. T-helper cells (Th) type 1 are considered to be involved in cell-mediated immunity, and Th2 in allergic reactions; the Th1/Th2 balance may be important in various pathological conditions. IFN-γ is a potent cytokine with a wide range of functions, including antiviral and immunomodulatory activities, and its major source is Th1. IL-4 is known as a major cytokine expressed by Th2. In bronchial epithelial cells, the Th1 cytokine IFN-γ is considered important in immunological reactions against pathogens, and the Th2 cytokines to play a role in allergic diseases such as asthma. In addition, clinical bronchial inflammation is often associated with a combination or imbalance of Th1 and Th2 reactions. Therefore, it is important to examine and compare the effects of IFN-γ and IL-4 on the function of bronchial epithelial cells. In the present study, it was found that IFN-γ ...
Cytokine production by Th1 or Th2-like cells before and after transfer. (A) At the time of transfer into recipient mice in vitro generated DO11.10 CD4 Th1, T
Both interferon gamma (IFN-gamma) produced by T helper 1 (TH1) lymphocytes and interleukin-4 (IL-4) produced by TH2 lymphocytes were reduced in either bulk circulating mononuclear cells or mitogen-induced CD4+ T cell clones from the peripheral blood of individuals infected with human immunodeficiency virus (HIV). There was a preferential reduction in clones producing IL-4 and IL-5 in the advanced phases of infection. However, enhanced proportions of CD4+ T cell clones producing both TH1-type and TH2-type cytokines (TH0 clones) were generated from either skin-infiltrating T cells that had been activated in vivo or peripheral blood T cells stimulated by antigen in vitro when cells were isolated from HIV-infected individuals. All TH2 and most TH0 clones supported viral replication, although viral replication was not detected in any of the TH1 clones infected in vitro with HIV. These results suggest that HIV (i) does not induce a definite TH1 to TH2 switch, but can favor a shift to the TH0 phenotype ...
Objective: A Th1 biased immune response in synovial fluid has been reported in children with polyarticular and extended oligoarticular-type juvenile idiopathic arthritis (JIA). We investigated T cell phenotypes including Th1, Th2, Th17, and Treg with emphasis on Th17 and Treg, in order to differentiate cytokines in the enthesitis-related arthritis (ERA) form of JIA. Methods: The frequencies of Th1, Th2, Th17, and Treg cells were determined by flow cytometry in peripheral blood (PB) and synovial fluid from patients with ERA and healthy subjects. Levels of interleukin 1β (IL-1β ), IL-6, IL-21, IL-23, and transforming growth factor β (TGF-β ), cytokines that influence Th17 lineage cells, were measured in paired plasma and synovial fluid (SF) samples by ELISA. Frequencies are expressed as percentages and cytokine levels as pg/ml. Results: There were no differences in blood samples in the frequency of Th1, Th2, Th17, and Treg cells between patients and controls. In paired samples, the median ...
Naive CD4(+) cells differentiate into T helper (Th1, Th2, Th9, Th17) and regulatory T (Treg) cells to execute their immunologic function. Whereas TGF-β suppresses Th1 and Th2 cell differentiation, this cytokine promotes Th9, Th17 and Foxp3(+) regulatory T cells depending upon the presence of other cytokines. IL-6 promotes Th17, but suppresses regulatory T cell differentiation. Moreover, natural but not TGF-β-induced regulatory T cells convert into Th17 cells in the inflammatory milieu. Here an update of T cell differentiation and conversion, as well as underlying mechanisms are given.. ...

T helper type 9 (TH9) cells can mediate tumor immunity and participate in autoimmune and allergic inflammation in mice, but little is known about the TH9 cells that develop in vivo in humans. We isolated T cells from human blood and tissues and found that most memory TH9 cells were skin-tropic or skin-resident. Human TH9 cells coexpressed tumor necrosis factor-α and granzyme B and lacked coproduction of TH1/TH2/TH17 cytokines, and many were specific for Candida albicans. Interleukin-9 (IL-9) production was transient and preceded the up-regulation of other inflammatory cytokines. Blocking studies demonstrated that IL-9 was required for maximal production of interferon-γ, IL-9, IL-13, and IL-17 by skin-tropic T cells. IL-9-producing T cells were increased in the skin lesions of psoriasis, suggesting that these cells may contribute to human inflammatory skin disease. Our results indicate that human TH9 cells are a discrete T cell subset, many are tropic for the skin, and although they may ...
We generated Th1 and Th2 lines by stimulating human cord blood lymphocytes with mitogen in the presence of IL-12 and neutralizing anti-IL-4 mAb or IL-4 and neutralizing anti-IL-12 mAb, respectively. As previously reported, this protocol allows the establishment of human T cell lines with strongly polarized cytokine production (8). As shown at the single cell level by measuring intracellular cytokine production (Fig. 1), neonatal T cells primed under the Th1 conditions differentiated into T cells producing IFN-γ but little IL-4, whereas naive T cells primed in the presence of IL-4 and anti-IL-12 resulted in a population of T cells producing mainly IL-4. To assess the selective expression of chemokine receptors in the different T cell subsets, we have analyzed the messenger RNA (mRNA) expression levels for the different chemokine receptors in both Th1 and Th2 lines, as well as in naive cells. As shown in Fig. 2, polarized Th1s and Th2s showed differential expression of chemokine receptors. Naive ...
In this dissertation the dependence of Th25/(33) cells on master transcription factors of already established T helper cell subsets (Th1, Th2 and Th17) was explored to fuel the question if the Th25/(33) cells are a new, distinct T helper cell lineage. CD4+ T cells from wild type mice and from transcription factor specific knockout mice (Tbet, STAT6 and RORγt) were polarised to Th25/(33) cells through the mentioned default stimulation, then the IL-25 production was assessed by Western Blot. It was shown that the Th25/(33) cells are independent of the transcription factors T-bet, STAT6 und RORγT and thus independent of the Th1-, Th2- und Th17-cell lineages. Therefore we assume that Th25/(33) cell are a new distinct T helper cell lineage ...
Helper activity of several murine CD4+ T cell subsets was examined. Effector Th, derived from naive cells after 4 days of in vitro stimulation with alloantigen, when generated in the presence of IL-4, secreted high levels of IL-4, IL-5, and IL-6, and low levels of IL-2 and IFN-gamma, and induced the secretion of all Ig isotypes particularly IgM, IgG1, IgA, and IgE from resting allogeneic B cells. Effectors generated with IL-6 secreted IL-2, IL-4, IL-5, IL-6, and IFN-gamma, and induced similar levels of total Ig, 25 to 35 micrograms/ml, but with IgM, IgG3, IgG1, and IgG2a isotypes predominating. Helper activity of these Th was significantly greater than that of effectors generated with IL-2 (10-15 micrograms/ml Ig) and of 24-h-activated naive and memory cells (2-4 micrograms/ml), both of which induced mainly IgM. Unlike other isotypes, IgE was induced only by effector Th generated with IL-4. Blocking studies showed that secretion of all isotypes in response to IL-6-primed effectors was dependent ...

The major goal of this study was to examine directly the capacity of Th1 cells to counterbalance the proasthmatic effects of Th2 cells in a murine model of asthma. The Th1/Th2 paradigm suggests that Th1 and Th2 cells counterbalance each other and that Th1 cells protect or prevent Th2-mediated allergic disease and asthma (27). However, using well-defined, phenotypically committed OVA-specific Th1 and Th2 cells expressing identical TCRs and adoptively transferred into either SCID mice or into OVA-immunized BALB/c mice, we found that OVA-specific Th1 cells failed to reverse Th2-mediated airway inflammation and airway hyperreactivity, even when given in twofold excess. These studies indicate that the Th1/Th2 paradigm, which predicts that Th1 cells downregulate allergic disease and asthma, may be more complex than initially appreciated and that suppression of allergic inflammation and Th2 activity in vivo may depend on cells other than Th1 lymphocytes.. Inasmuch as asthma is associated with the ...
Parkinsons disease (PD) affects an estimated 7 to 10 million people worldwide, and only symptomatic treatments are presently available to relieve the consequences of brain dopaminergic neurons loss. Neuronal degeneration in PD is the consequence of neuroinflammation in turn influenced by peripheral adaptive immunity, with CD4+ T lymphocytes playing a key role. CD4+ T cells may however acquire proinflammatory phenotypes, such as T helper (Th) 1 and Th17, as well as anti-inflammatory phenotypes, such as Th2 and the T regulatory (Treg) one, and to what extent the different CD4+ T cell subsets are imbalanced and their functions dysregulated in PD remains largely an unresolved issue. We performed two cross-sectional studies in antiparkinson drug-treated and drug-naïve PD patients, and in age- and sex-matched healthy subjects. In the first one, we examined circulating Th1, Th2, Th17, and in the second one circulating Treg. Number and frequency of CD4+ T cell subsets in peripheral blood were assessed by flow

N2 - OBJECTIVES: We recently reported increased CD4 CD25 T regulatory (Treg) activity after burn injury in mice. This study sought to determine if Tregs mediate the reduction in TH1-type immunity after serious injury in man and if Treg function is altered by injury. METHODS: Peripheral blood was withdrawn from 19 consenting adult patients (35.1 ± 16.3 years of age) with Injury Severity Scores (ISS) 36.6 ± 13.9 on days 1 and 7 after trauma and from 5 healthy individuals. CD4 T cells were purified and sorted into Treg (CD25) and Treg-depleted populations. After activation of cells with anti-CD3/CD28 antibody, production of the TH1-type cytokine ...

We have previously shown that mice lacking inducible NO synthase are markedly more susceptible to Leishmania major infection but developed a significantly enhanced Th1 cell response compared with wild-type mice. Furthermore, at high concentrations, NO inhibited IL-12 synthesis by activated macrophages, thereby indirectly suppressing the expansion of Th1 cells. We report here that at low concentrations, NO selectively enhanced the induction of Th1 cells and had no effect on Th2 cells. NO exerted this effect in synergy with IL-12 during Th1 cell differentiation and had no effect on fully committed Th1 cells. NO appears to affect CD4+ T cells directly and not at the antigen-presenting cells. These results therefore provide an additional pathway by which NO modulates the immune response and contributes to the homeostasis of the immune system.. ...
To what extent proinflammatory Th17 cells and defects in Treg-mediated regulation contribute to the development of type 1 diabetes in humans is highly debated. Here we show that the PLNs of patients with type 1 diabetes, unlike their PB, have an altered immune status due to the expansion of Th17 cells and the presence of CD25bright T cells epigenetically imprinted to have a regulatory activity but which lack a proper function.. Increased Th17 cells in the PB of children with diabetes has been recently reported (8), and Tan and colleagues (9) have demonstrated that these circulating IL-17-producing T cells may reside mainly within the CD4+CD45RA−CD25intFOXP3low cells. Although expressing FOXP3, this latter cell subset does not have suppressive activity, but rather, it has a helper function and contains proinflammatory cytokine-producing cells (40,41). Our data demonstrate that the expansion of Th17 immunity is also present in the target organ of patients with long-term diabetes. However, this ...

The role of Th17 cells in colorectal tumorigenesis and development still remains unclear, despite the fact that it has been established in the pathogenesis of autoimmune diseases. We first analyzed Th17 cells and Treg cells using flow cytometry in the circulation of colorectal adenoma (CRA) and colorectal carcinoma (CRC) patients and healthy controls, and the frequency of Th17 cells in peripheral blood mononuclear cells (PBMCs) stimulated by anti-CD3 plus anti-CD28 and treated by IL-1β, IL-6, and TGF-β in different concentrations. We then detected cytokines IL-1β, IL-6, IL-17A, IL-21, IL-23 or TGF-β by ELISA in sera and supernatants from both normal and tumor tissues cultured ex vivo. It was found that the percentage of Th17 and Treg cells increased in the circulation of both CRA and CRC patients; the increase of Th17 cells in the circulation occurred in early stages, whereas the increase of Treg cells in the circulation and the increase of Th17 cells in tumor tissues occurred in advanced stages.

The frequencies of IL-17-secreting CD4 T cells (Th17) are significantly increased in the LNs of DED mice and they have been demonstrated to be a critical CD4+ population in DED. 7,8 Notably, they have been reported as displaying a relative resistance to T regulatory suppression. 9 Additionally, their effector functions in DED include, but are not limited to, the stimulation of lymphangiogenesis and direct disruption of the corneal epithelial barrier via upregulating MMP expression. 8 In our DED mouse model, Th1 cells frequencies in the DLNs are not increased after disease induction and anti-CCR7 treatment showed no effect on Th1 cells (Supplementary Fig. S1). Clearly, several inflammatory molecules, including cytokines, chemokines, and MMPs, are increased in the cornea and conjunctiva in DED. 7 However, in this study we focused on Th17-associated molecules and inflammation markers. Our findings showing decreased frequencies of Th17 cells in LNs, as well as reduced IL-17 mRNA expression in the ...

Substantial advances in our understanding of the developmental and functional relationship between regulatory T cells (Tregs) and T helper 17 (TH17) cells and their potential clinical applications have been made. In response to these breakthroughs, the second international conference entitled China Tregs/Th17 2010 Shanghai Conference, held in Shanghai, China, was dedicated to this topic. Various types of Tregs and TH17 cells, as well as their relevant cytokines, were discussed. Here, we summarize some of the findings shared at the conference, specifically focusing on the biology of TH17 cells, including interleukin-17 (IL-17)-producing innate cells, Tregs, and the factors that control the critical balance between Tregs and cells of the TH17 lineage.. ...

1999). Interleukin (IL)-12p70 production by dendritic cells has a pivotal role in induction of Th1 responses and IL-10 is emerging as a key mediator for induction of regulatory T cells; and while prostaglandin (PG)E2 is one of a number of mediators postulated to drive the development of Th2 effector cells, critical mediators of Th2 effector cell development are not well characterized. Different TLR ligands are reported to preferentially favor Th1- or Th2-biased adaptive immune responses. TLR2 ligands generally favor Th2 responses whereas immunostimulatory viral/bacterial DNA (immunostimulatory sequence oligodeoxynucleotides, ISS-ODNs, also called CpG) that signal via Flagellated bacteria m Gra gi u F n TLR10 TLR4 TLR6 TLR5 TLR2 Plasma membrane TLR1 Viral ssRNA Viral/bacterial DNA Viral dsRNA TLR7 TLR8 TLR3 24 TLR9 Intracellular vesicle membrane Fig. 1932) Das Freiwarden eines histaminhnlichen.
