Natural killer (NK) cells are key components of the immune system involved in several immune reactions, including the clearance of intracellular pathogens. When activated, NK cells rapidly secrete particular cytokines that activate innate immunity and facilitate development of adaptive responses. Conflicting reports on the role of NK cells during infection by Listeria monocytogenes can be found in the literature. Here, we demonstrate that during lethal infection by L. monocytogenes, activation of NK cells via the costimulatory molecule CD27 leads to excessive IFN‐γ production. This impairs innate anti‐bacterial host defenses by inducing downregulation of CXCR2 on granulocytes and consequently inhibiting their recruitment to the sites of infection. The use of antibodies to block CD27 signaling or to deplete IFN‐γ was sufficient to rescue mice from lethal challenge by L. monocytogenes. Our findings contribute to a better understanding of the importance of CD27 signaling in activation of NK cells and should provide new ways of interfering with infections. 相似文献

With increasing interest in alternative options to interferon‐alpha‐based treatments, IFN‐λ has shown therapeutic promise in a variety of diseases. Although the antiviral activity of IFN‐λ has been extensively studied, there is limited knowledge regarding the immunological functions of IFN‐λ and how these differ from those of other classes of IFNs. In this study, we investigated the effects of IFN‐λ on primary human NK cells, both in a direct and indirect capacity. We demonstrate that in contrast to interferon‐alpha, IFN‐λ is unable to directly stimulate NK cells, due to the absence of IFN‐λ receptor chain 1 (IFN‐λR1) on NK cells. However, IFN‐λ, in combination with TLR4 challenge, is able to induce the production of select members of the IL‐12 family of cytokines in monocyte‐derived macrophages. We further show that through macrophage‐mediated IL‐12 production, IFN‐λ is able to indirectly affect NK cells and ultimately induce IFN‐γ production. 相似文献

IFN‐γ‐producing NKT cells exacerbate sepsis by enhancing C5a generation via IL‐10‐mediated inhibition of CD55 expression on neutrophils 下载免费PDF全文

A role for NKT cells has been implicated in sepsis, but the mechanism by which NKT cells contribute to sepsis remains unclear. Here, we examined WT and NKT‐cell‐deficient mice of C57BL/6 background during cecal ligation and puncture‐induced sepsis. The levels of C5a, IFN‐γ, and IL‐10 were higher in the serum and peritoneal fluid of WT mice than in those of CD1d?/? mice, while the mortality rate was lower in CD1d?/? mice than in WT mice. C5a blockade decreased mortality of WT mice during sepsis, whereas it did not alter that of CD1d?/? mice. As assessed by intracellular staining, NKT cells expressed IFN‐γ, while neutrophils expressed IL‐10. Upon coculture, IL‐10‐deficient NKT cells enhanced IL‐10 production by WT, but not IFN‐γR‐deficient, neutrophils. Meanwhile, CD1d?/? mice exhibited high CD55 expression on neutrophils during sepsis, whereas those cells from WT mice expressed minimal levels of CD55. Recombinant IL‐10 administration into CD1d?/? mice reduced CD55 expression on neutrophils. Furthermore, adoptive transfer of sorted WT, but not IFN‐γ‐deficient, NKT cells into CD1d?/? mice suppressed CD55 expression on neutrophils, but increased IL‐10 and C5a levels. Taken together, IFN‐γ‐producing NKT cells enhance C5a generation via IL‐10‐mediated inhibition of CD55 expression on neutrophils, thereby exacerbating sepsis. 相似文献

Previous studies have shown that EAE can be elicited by the adoptive transfer of either IFN‐γ‐producing (Th1) or IL‐17‐producing (Th17) myelin‐specific CD4+ T‐cell lines. Paradoxically, mice deficient in either IFN‐γ or IL‐17 remain susceptible to EAE following immunization with myelin antigens in CFA. These observations raise questions about the redundancy of IFN‐γ and IL‐17 in autoimmune demyelinating disease mediated by a diverse, polyclonal population of autoreactive T cells. In this study, we show that an atypical form of EAE, induced in C57BL/6 mice by the adoptive transfer of IFN‐γ‐deficient effector T cells, required IL‐17 signaling for the development of brainstem infiltrates. In contrast, classical EAE, characterized by predominant spinal cord inflammation, occurred in the combined absence of IFN‐γ and IL‐17 signaling, but was dependent on GM‐CSF and CXCR2. Our findings contribute to a growing body of data, indicating that individual cytokines vary in their importance across different models of CNS autoimmunity. 相似文献

Mycobacterium tuberculosis (Mtb) 38‐kDa antigen is an immunogenic lipoprotein that induces strong T‐cell responses in experimental animals. However, there is limited information on the role of this antigen in human population. In this article, we present the dynamics of pro‐inflammatory (IFN‐γ and TNF‐α) and anti‐inflammatory cytokine (IL‐10) against the 38 kDa in cohorts of pulmonary TB (PTB) patients, household contacts (HHCs), and community controls (CCs) in a high endemic setting. Whole blood assay was used to determine the levels of cytokines in 149 patients, 149 HHCs, and 68 CCs at baseline, 6 months, and 12 months. At baseline, the level of IFN‐γ was significantly (p < 0.0001) higher in CCs and HHCs than in untreated patients. CCs had significantly (p < 0.05) higher level of IFN‐γ than HHCs. There was no significant difference between treated and untreated patients, and there was no significant change in HHCs over 12 months. At baseline, the levels of IL‐10 and TNF‐α were significantly (p < 0.0001) higher in patients than in HHCs and CCs. No significant change was observed between treated patients and untreated patients and HHCs over time. The study shows that IFN‐γ against the 38 kDa discriminates clinical TB from infection and infection from exposure, suggesting its potential for immune protection and diagnosis. 相似文献

Natural killer (NK) cells are innate lymphocytes that are able to directly kill tumor cells through different mechanisms including ligation of TNF‐related apoptosis‐inducing ligand (TRAIL) receptors. Zoledronic acid (ZA) is a bisphosphonate known to upregulate the expression of TRAIL on human γδ T cells. Here, we investigated whether exposure to ZA would upregulate TRAIL expression on human NK cells and augment their cytotoxicity against tumor cells. When cocultured with monocytes, treatment with ZA and IL‐2 resulted in a significant upregulation of TRAIL expression on human NK cells (p = 0.002). Consequently, ZA‐primed NK cells were significantly more cytotoxic against TRAIL sensitive tumor cells (p < 0.0001). In the presence of ZA and IL‐2, monocytes produced high levels of IFN‐γ; when cultured in the presence of neutralizing antibodies to IFN‐γ, TRAIL expression and TRAIL‐mediated cytotoxicity of NK cells were significantly reduced. Furthermore, in tumor‐bearing SCID/Beige mice, a significant delayed tumor progression and prolonged survival was observed after infusion of ZA‐primed NK cells compared with that observed in mice infused with unprimed NK cells. These findings represent a novel approach to potentiate TRAIL‐mediated apoptosis by adoptively infused NK cells that could improve the outcome in patients with cancer. 相似文献

Following immunization with collagen II (CII) in complete Freund's adjuvant (CFA), DBA/1 mice develop arthritis of major joints. This collagen‐induced arthritis (CIA) is used as a model for rheumatoid arthritis (RA) in man. Inflammatory changes in lung tissue commonly occur in RA. However, evidence for pulmonary inflammation in CIA is scarce and ambiguous. Here, we demonstrate pulmonary inflammation accompanying CIA in wild‐type DBA/1 mice. In IFN‐γ receptor‐deficient (IFN‐γR KO) mice, inflammation was more frequent and more severe. Injection of CFA only (without CII) proved to be as efficient in eliciting pulmonary inflammation as immunization with CFA + CII, though being less effective in causing arthritis. Significant correlation in severity between joint and pulmonary involvement could not be demonstrated. Macroscopic, microscopic, and functional characteristics of pulmonary inflammation in the mice resembled those seen in human RA. Increased inflammation in IFN‐γR KO mice was accompanied by augmented expression of various cytokines and chemokines, as measured by RT‐PCR on affected tissue. Treatment with a TNF‐α inhibitor ameliorated lung pathology. We conclude that CIA in DBA/1 mice is accompanied by pulmonary inflammation. Although both disease processes are kept in check by endogenous IFN‐γ, lack of strict parallelism indicates that overlap in their pathogeneses is partial. 相似文献

Pulmonary Chlamydia muridarum challenge activates lung interstitial macrophages which correlate with IFN‐γ production and infection control in mice 下载免费PDF全文

Protective immunity to the pathogen Chlamydia is dependent on a robust IFN‐γ response generated by innate and adaptive lymphocytes. Here we assess the role of the macrophage in orchestrating a protective response in vivo to the murine pathogen, Chlamydia muridarum. During acute pulmonary and peritoneal infection, resident macrophages in both sites are infected with C. muridarum and adopt an inflammatory phenotype. In the lung, this activation is restricted to interstitial macrophages, which harbor higher levels of C. muridarum 16sRNA than alveolar macrophages. We examined innate and adaptive lymphocyte activation in the peritoneal cavity with macrophage depletion and with adoptive transfer of infected macrophages. These experiments demonstrate macrophage activation correlates with a protective IFN‐γ response and effective control of C. muridarum. These studies suggest that a quantitative or qualitative alteration in macrophages may play a key role in the development of Chlamydia‐associated diseases. 相似文献

We show here that the expression of 4–1BB is rapidly induced in γδ T cells following antigenic stimulation in both mice and humans, and ligation of the newly acquired 4–1BB with an agonistic anti‐4–1BB augments cell division and cytokine production. We further demonstrate that γδ rather than αβ T cells protect mice from Listeria monocytogenes (LM) infection and 4–1BB stimulation enhances the γδ T‐cell activities in the acute phase of LM infection. IFN‐γ produced from γδ T cells was the major soluble factor regulating LM infection. Vγ1+ T cells were expanded in LM‐infected mice and 4–1BB signal triggered an exclusive expansion of Vγ1+ T cells and induced IFN‐γ in these Vγ1+ T cells. Similarly, 4–1BB was induced on human γδ T cells and shown to be fully functional. Combination treatment with human γδ T cells and anti‐hu4–1BB effectively protected against LM infection in human γδ T cell‐transferred NOD‐SCID mice. Taken together, these data provide evidence that the 4–1BB signal is an important regulator of γδ T cells and induces robust host defense against LM infection. 相似文献

Lipoarabinomannan (LAM) is a virulent factor used for entry and survival of Mycobacterium tuberculosis (Mtb) in macrophages. Although the role of LAM for the diagnosis of tuberculosis (TB) has been extensively investigated, its cytokine response during natural Mtb infection in humans is largely unknown. In this study, LAM‐specific IFN‐γ, TNF‐α, and IL‐10 levels following whole blood assay were measured in untreated pulmonary TB patients, their contacts and community controls at baseline. In treated patients and contacts, cytokines were also measured at 6 and 12 months. At entry, 52.8% and 74.8% of controls and contacts were QFT‐GIT positive, respectively. At baseline, untreated TB patients and contacts had significantly lower IFN‐γ and TNF‐α response compared to community controls (p < 0.0001). Besides, untreated patients had significantly higher TNF‐α and IL‐10 response compared to their contacts (p < 0.0001). At 6 months, contacts and treated TB patients had significantly increased INF‐γ and TNF‐α response (p < 0.0001). In TB patients, IFN‐γ increased 10‐fold following chemotherapy suggesting its potential role for treatment monitoring. The data suggests that LAM might have an anti‐inflammatory effect during clinical TB and early Mtb infection. The data also suggests that LAM‐induced IFN‐γ and TNF‐α could be used as biomarkers of protective immunity. 相似文献

γδ T cells restrain extrathymic development of Foxp3+‐inducible regulatory T cells via IFN‐γ 下载免费PDF全文
Inducible Treg (iTreg) cells generated from Ag‐stimulated naïve CD4+ T cells in the periphery play an important role in regulating immune responses. TGF‐β is a key cytokine that promotes this conversion process; however, how this process is regulated in vivo remains unclear. Here, we report that γδ T cells play a crucial role in controlling iTreg generation and suppressor function. Ag‐induced iTreg generation was significantly enhanced in C57BL/6 mice in the absence of γδ T cells. Inhibition of iTreg conversion was mediated by IFN‐γ produced by activated γδ T cells but not by activated CD4+ T cells. BM chimera experiments further confirmed γδ‐derived IFN‐γ‐dependent mechanism in regulating iTreg generation in vivo. Lastly, human peripheral blood γδ T cells also interfere with iTreg conversion via IFN‐γ. Our results suggest a novel function of γδ T cells in limiting the generation of iTreg cells, potentially balancing immunity and tolerance. 相似文献

Clinical efficacy in the treatment of rheumatoid arthritis with anti‐CD20 (Rituximab)‐mediated B‐cell depletion has garnered interest in the mechanisms by which B cells contribute to autoimmunity. We have reported that B‐cell depletion in a murine model of proteoglycan‐induced arthritis (PGIA) leads to an increase in Treg cells that correlate with decreased autoreactivity. Here, we demonstrate that the increase in Treg cells after B‐cell depletion is due to an increase in the differentiation of naïve CD4+ T cells into Treg cells. Since the development of PGIA is dependent on IFN‐γ and B cells are reported to produce IFN‐γ, we hypothesized that B‐cell‐specific IFN‐γ plays a role in the development of PGIA. Accordingly, mice with B‐cell‐specific IFN‐γ deficiency were as resistant to the induction of PGIA as mice that were completely IFN‐γ deficient. Importantly, despite a normal frequency of IFN‐γ‐producing CD4+ T cells, B‐cell‐specific IFN‐γ‐deficient mice exhibited a higher percentage of Treg cells compared with that in WT mice. These data indicate that B‐cell IFN‐γ production inhibits Treg‐cell differentiation and exacerbates arthritis. Thus, we have established that IFN‐γ, specifically derived from B cells, uniquely contributes to the pathogenesis of autoimmunity through prevention of immunoregulatory mechanisms. 相似文献

Chronic Trichuris muris infection alters hematopoiesis and causes IFN‐γ‐expressing T‐cell accumulation in the mouse bone marrow 下载免费PDF全文

Proinflammatory cytokines produced during immune responses to infectious stimuli are well‐characterized to have secondary effects on the function of hematopoietic progenitor cells in the BM. However, these effects on the BM are poorly characterized during chronic infection with intestinal helminth parasites. In this study, we use the Trichuris muris model of infection and show that Th1 cell‐associated, but not acute Th2 cell‐associated, responses to chronic T. muris infection cause a major, transient expansion of CD48?CD150? multipotent progenitor cells in the BM that is dependent on the presence of adaptive immune cells and IFN‐γ signaling. Chronic T. muris infection also broadly stimulated proliferation of BM progenitor cells including CD48?CD150+ hematopoietic stem cells. This shift in progenitor activity during chronic T. muris infection correlated with a functional increase in myeloid colony formation in vitro as well as neutrophilia in the BM and peripheral blood. In parallel, we observed an accumulation of CD4+, CD8+, and CD4?CD8? (double negative) T cells that expressed IFN‐γ, displaying activated and central memory‐type phenotypes in the bone marrow during chronic infection. Thus, these results demonstrate that Th1 cell‐driven responses in the intestine during chronic helminth infection potently influence upstream hematopoietic processes in the BM via IFN‐γ. 相似文献

IFN‐γ directly inhibits murine B‐cell precursor leukemia‐initiating cell proliferation early in life 下载免费PDF全文

The early‐life immune environment has been implicated as a modulator of acute lymphoblastic leukemia (ALL) development in children, with infection being associated with significant changes in ALL risk. Furthermore, polymorphisms in several cytokine genes, including IL‐10 and IFN‐γ, are associated with leukemia development. However, the mechanisms and timing of these influences remain unknown. Here, we use the Eμ‐ret transgenic mouse model of B‐cell precursor ALL to assess the influence of IFN‐γ on the early‐life burden of leukemia‐initiating cells. The absence of IFN‐γ activity resulted in greater numbers of leukemia‐initiating cells early in life and was associated with accelerated leukemia onset. The leukemia‐initiating cells from IFN‐γ‐knockout mice had reduced suppressor of cytokine signaling (SOCS‐1) expression, were significantly more sensitive to IFN‐γ, and exhibited more rapid expansion in vivo than their wild‐type counterparts. However, sensitivity to this inhibitory pathway was lost in fully transformed IFN‐γ‐knockout leukemia cells. These results demonstrate that the influence of IFN‐γ on ALL progression may not be mediated by selection of nascent transformed cells but rather through a general SOCS‐mediated reduction in B‐cell precursor proliferation. Thus, while cytokine levels may influence leukemia at multiple points during disease progression, our study indicates a significant early influence of basal, infection‐independent cytokine production on leukemogenesis. 相似文献

Association of ESAT‐6/CFP‐10‐induced IFN‐γ, TNF‐α and IL‐10 with clinical tuberculosis: evidence from cohorts of pulmonary tuberculosis patients,household contacts and community controls in an endemic setting 下载免费PDF全文

Mycobacterium tuberculosis (Mtb) early secreted protein antigen 6 (ESAT‐6) and culture filtrate protein 10 (CFP‐10) are among candidate vaccines against tuberculosis (TB). Results of experimental animal models show that these antigens are associated with induction of strong T cell immunity [interferon (IFN)‐γ production], while others report that these proteins as virulent factors involved in pathogenicity of Mtb infection. However, the role of ESAT‐6/CFP‐10 during natural Mtb infections in humans has not been established. In this paper we present results of a longitudinal study from an Mtb‐infected human population from an endemic setting. Whole blood assay was used to determine levels of IFN‐γ, tumour necrosis factor (TNF)‐α and interleukin (IL)‐10 against rESAT‐6/CFP‐10 in TB patients, household contacts and community controls. The levels of IFN‐γ, TNF‐α and IL‐10 against rESAT‐6/CFP‐10 at baseline were significantly higher in patients and community controls than in household contacts. In patients, no significant difference was observed in the level of these cytokines before and after chemotherapy whereas, in contacts, the level of these cytokines increased significantly and progressively over time. The study shows that the levels of IFN‐γ, TNF‐α and IL‐10 against rESAT‐6/CFP‐10 are depressed during Mtb infection or exposure but are elevated during clinical TB. Our findings from a study of naturally infected human population suggest that IFN‐γ, TNF‐α and IL‐10 against rESAT‐6/CFP‐10 are markers for clinical TB but not for protective immunity. 相似文献

Synergistic antiviral activity of Sofosbuvir and type‐I interferons (α and β) against Zika virus 下载免费PDF全文

Zika virus (ZIKV) is transmitted by mosquitoes and causes Dengue‐like illness, neurological symptoms such as Guillain‐Barré Syndrome and microcephaly in children born to infected pregnant mothers. Recently, the World Health Organization (WHO) declared ZIKV infection as a Global Health Emergency. However, there are no known prophylactic or therapeutic measures against this virus. As a proof of concept toward combination therapeutic strategy against ZIKV, combinations of host‐targeted (Interferon‐α and Interferon‐β) and direct acting (Sofosbuvir) antivirals were evaluated in a hepatic cell line (Huh7) using a Cytoprotection (CP) assay. The combination of these antivirals resulted in synergistic inhibition of ZIKV infection in the in vitro CP assay. Additional testing in a ZIKV yield assay demonstrated that combination treatment of these antivirals conferred >2‐log reduction in the release of viral RNA. Measurement of ZIKV proteins in the cells infected with multiple ZIKV strains isolated from different geographical regions (Americas, Asia, and Africa) using an immunofluorescence assay confirmed the effective antiviral activity of this combination against ZIKV. These results demonstrate the in vitro proof of concept (POC) for using a combination approach utilizing the strengths of both virus and host‐targeted antivirals. These results suggest the effectiveness of the combination strategy in combating ZIKV, in the in vitro systems. Further evaluation of such combination therapies in vivo might provide an impetus for the development of effective ZIKV therapeutic strategies. 相似文献

Accelerated tumour metastasis due to interferon‐γ receptor‐mediated dissociation of perivascular cells from blood vessels 下载免费PDF全文

Angiostasis mediated by interferon (IFN)‐γ is a key mechanism of anti‐tumour immunity; however, the effect of IFN‐γ on host vascular endothelial growth factor A (VEGFA)‐expressing cells during tumour progression is still elusive. Here, we developed transgenic mice with IFN‐γ receptor (IFNγR) expression under control of the Vegfa promoter (V‐γR). In these mice, the IFN‐γ responsiveness of VEGFA‐expressing cells led to dramatic growth suppression of transplanted lung carcinoma cells. Surprisingly, increased mortality and tumour metastasis were observed in the tumour‐bearing V‐γR mice, in comparison with the control wild‐type and IFNγR‐deficient mice. Further study showed that perivascular cells were VEGFA‐expressing cells and potential IFN‐γ targets. In vivo, tumour vascular perfusion and pericyte association with blood vessels were massively disrupted in V‐γR mice. In vitro, IFN‐γ inhibited transforming growth factor‐β signalling by upregulating SMAD7, and therefore downregulated N‐cadherin expression in pericytes. Importantly, IFN‐γ neutralization in vivo with a monoclonal antibody reduced tumour metastasis. Together, the results suggest that IFNγR‐mediated dissociation of perivascular cells from blood vessels contributes to the acceleration of tumour metastasis. Thus, the inhibition of tumour growth via IFN‐γ‐induced angiostasis might also accelerate tumour metastasis. Copyright © 2017 Pathological Society of Great Britain and Ireland.
