[PMID: 37484355 PMCID: PMC10361377 DOI: 10.1016/j.heliyon.2023.e17427] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 04/22/2023] [Accepted: 06/16/2023] [Indexed: 07/25/2023] Open
Abstract
Background interleukin 23 (IL-23) is an important factor involved in the survival and proliferation of T helper 17 cells (Th17), known for their implication in multiple sclerosis (MS). By contrast, IL-27 regulates and modulates the function of T lymphocytes, in particular as a suppressor of Th17 differentiation. The aims of the study were i) to test the association of cytokines with the clinical and genetic characteristics in each of the multiple sclerosis groups (CIS - clinically isolated syndrome, RRMS - relapsing-remitting MS and SPMS - Secondary progressive MS) and ii) to evaluate the association between serum levels of IL-23 and IL-27 with T4730C (IL-27), A964G (IL-27) and R381Q (IL-23) gene polymorphisms in RRMS patients. Methods Blood samples were obtained from 82 patients diagnosed with MS under treatment with glatiramer acetate (GA), interferon beta (IFN) 1 A and 1 B. IL-23 and IL-27 serum concentrations were measured by enzyme-linked immunosorbant assay (ELISA). Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used in order to determine the genotypes for R381Q (IL-23) polymorphisms, T4730C (IL-27) and A964G (IL-27). Results Patients with SPMS, RRMS and CIS respectively differed significantly regarding age distribution (p = 0.003) but the studied MS groups were similar regarding age at disease onset (p = 0.528) and treatment type (p = 0.479). A significant increase of mean serum IL-27 was noticed in cases with early onset (age at disease onset <28 years) of RRMS (mean difference: 4.2 pg/ml, 95% CI: 0.8-5.3 pg/ml), compared to cases with later onset of RRMS (age at disease onset ≥28 years). RRMS patients with wild GG genotype of R381Q (IL-23) showed a significant increase of mean serum IL-23 than patients with variant AG genotype (mean difference: 115.1 pg/ml, 95% CI: 8.6-221.6 pg/ml). A trend for a higher increase in means of serum IL-23 (p = 0.086) was observed in RRMS patients carriers of AA genotype of A964G (IL-27) polymorphism in comparison with patients with AG or GG genotypes. We found no significant monotonic correlation of IL-27, IL-23 serum levels with age at disease onset (years) and duration of disease (p > 0.05) in the CIS and SPMS group respectively but a significant correlation between IL-23 and the duration of disease-modifying treatment was noticed only in the SPMS group. Conclusions The results of the current study suggest an association between IL-23 levels and the R381Q gene polymorphism and also a relationship between IL-27 serum levels and early age at disease onset in RRMS patients.

Potential Contribution of IL-27 and IL-23 Gene Polymorphisms to Multiple Sclerosis Susceptibility: An Association Analysis at Genotype and Haplotype Level. J Clin Med 2021; 11:jcm11010037. [PMID: 35011777 PMCID: PMC8745323 DOI: 10.3390/jcm11010037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 12/17/2021] [Accepted: 12/18/2021] [Indexed: 11/30/2022] Open
Abstract
(1) Background: interleukin 23 (IL-23) and interleukin 27 (IL-27) modulate the activity of T helper 17 cells (Th17) with critical roles in autoimmune diseases and multiple sclerosis (MS). The genes responsible for cytokine generation are highly influenced by the presence of single nucleotide polymorphisms (SNP) in main regions such as regulatory sequences or in promoter regions, contributing to disease susceptibility and evolution. The present study analyzed the associations of IL-23 and IL-27 SNPs with susceptibility to multiple sclerosis. (2) Methods: We performed a case-control study including 252 subjects: 157 patients diagnosed with MS and 95 controls. We used polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) to determine the genotypes for IL-27 T4730C (rs 181206), IL-27 A964G (rs 153109), and IL-23 receptor gene (IL-23R) G1142A (rs 11209026). (3) Results: The IL27-T4730C gene polymorphism was significantly associated with an increased odds of MS under the dominant genetic model (TC + CC variant genotypes, adjusted odds ratio OR = 4.06, 95% CI: 2.14–7.83, p-value = 0.000007, Q-value = 0.000063). Individuals carrying the IL-27 A924G variant (AG + GG) genotype presented higher odds of MS compared to non-carriers under the dominant model (adjusted OR = 1.93, 95% CI: 1.05–3.51, p-value = 0.0324, Q-value = 0.05832) and the allelic genetic model (unadjusted p-value = 0.015, OR = 1.58, 95% CI: 1.09–2.28), while IL-23-R381Q SNP conferred a decreased odds of MS under a codominant model of inheritance (adjusted OR = 0.26, 95% CI: 0.08–0.92, p-value = 0.0276, Q-value = 0.058) and an allelic model (unadjusted p-value = 0.008, OR = 0.23, 95% CI: 0.07–0.75). In an additive model with adjustment for age group (≤40 years vs. >40 years), sex and smoking, patients carrying the G-C (A964G, T4730C) haplotype had a 3.18 increased risk (95% CI: 1.74–5.81, p < 0.001) to develop multiple sclerosis. (4) Conclusions: The results of the current study showed a significant relationship of IL-27-A964G and IL-27-T4730C polymorphisms with increased risk of MS, and also the protective role of the IL-23-R381Q polymorphism. Moreover, the haplotype-based analysis proposed the mutant G-C (A924G, T4730C) as a significant risk haplotype for the development of MS.

Abstract
INTRODUCTION Accumulating evidence has indicated that interleukin (IL)-27 and its gene polymorphisms exert pivotal impact on several autoimmune disorders. This research intended to investigate the relationship between IL-27 rs153109 polymorphism with risk and prognosis for aplastic anemia. METHODS IL-27 rs153109 polymorphism was detected with polymerase chain reaction-ligase detection reaction in 238 patients with aplastic anemia and 215 normal individuals. Enzyme-linked immunosorbent assays were applied to measure the plasma level of IL-27. RESULTS Frequencies of rs153109 AA and GG genotype were statistically higher in aplastic anemia patients compared to controls. Similar results were observed when further divided patients into nonsevere and severe ones. That means carriers of AA and GG genotype are accompanied by an increased risk of developing aplastic anemia. Plasma IL-27 levels of aplastic anemia patients were remarkably elevated than normal group and had positive relation with disease severity. Furthermore, patients with AA genotype had obviously higher IL-27 levels than ones with AG and GG genotype. Moreover, patients carrying AA genotype exhibited a poorer reaction to immunosuppressive therapy and were more prone to clonal evolution. CONCLUSION IL-27 rs153109 polymorphism confers genetic predisposition to aplastic anemia and influences disease prognosis, potentially by regulating IL-27 expression, which help broaden potential pathogenesis of aplastic anemia. Specifically, for patients with AA genotype, more aggressive therapeutic strategies such as hematopoietic stem cells transplantation are warranted.

Abstract
BACKGROUND Multiple sclerosis (MS) is one of the most debilitating neurological diseases of young adults. The presence of a single nucleotide polymorphism in the promoter regions of the interleukin 27 gene (IL27 T4730C, rs181206) may alter the transcription and the production of cytokine levels, leading to MS. PATIENTS AND METHODS We performed a case-control study including 82 individuals: 51 patients diagnosed with MS and 31 healthy controls. Polymerase chain reaction-restriction fragment length polymorphism was used in order to determine the genotypes for the IL27 T4730С polymorphism and enzyme-linked immunosorbent assay to measure the serum IL27 level. RESULTS Carriers of the T4730С polymorphism were found to have a 6-fold [95% confidence intervaI (CI)=1.83-19.63, p=0.002] increased risk for MS. Univariate logistic regression analysis showed an increased frequency of the TC4730 heterozygous genotype (39.2% vs. 9.7%) and also of the C4730 allele (27.45% vs. 8.06) in patients compared to controls, with a 6.02-fold increased risk (95% CI=1.61-22.46, p=0.006) and a 4.31-fold increased risk (95% CI=1.57-11.87, p=0.002) of developing MS. IL27 levels were significantly lower in patients compared to controls (12.35 versus 14.34 pg/ml, p=0.039), without significant differences between genotypes. Multivariate logistic analysis showed that IL27 T4730C polymorphism (odds ratio=6.272, 95% CI=1.84-21.40, p=0.003) and smoking (odds ratio=4.214, 95% CI=1.39-12.74, p=0.011) represented independent risk factors for MS. CONCLUSION Our study provides a possible link between IL27 level and IL27 T4730C gene polymorphism and the risk for developing MS in a Romanian population.

Abstract
OBJECTIVE Cytokine polymorphisms have been associated with systemic lupus erythematosus (SLE) pathogenicity. Interleukin 27 (IL-27) is an important one of pro-/anti-inflammatory cytokine. It has been reported in various Th1/Th17-mediated inflammatory disorders, and even in Th2-complexed diseases, such as SLE. In our preliminary study, the aim was to investigate the potential roles of single nucleotide polymorphism (SNP) -964A/G (rs153109) and + 2905 T/G (rs17855750) in an IL-27p28 gene on susceptibility to SLE. METHODS The 112 Egyptian SLE patients against 101 healthy persons were enrolled in this work. The polymerase chain reaction/restriction fragment length polymorphism (PCR-RFLP) is used for genotyping IL-27 SNPs. RESULTS No significant variations were found between patients and control in the genotype and allele frequencies of IL-27p28 (-964A/G). SLE patients have a significant increase in the frequency of IL-27p28 (+ 2905 T/G) TG genotype (P < 0.01) and G allele (P < 0.01) compared to controls. Complete disappearance of GG genotype was demonstrated in both groups. G allele might have considered a disease risk factor with odd ration (OR) = 9.184. From four possible haplotypes, the frequency of AT haplotype elevated in both examined groups. CONCLUSION This was the first study on the Egyptian population for studying the relation between IL-27 SNPs and SLE. Our preliminary study indicated that both TG genotype and G allele of IL-27p28 (+ 2905 T/G) could consider risk factors for SLE. Key Points • This article provides an information about the relation between systemic lupus erythematosus and interleukin-27 cytokine by detection single nucleotide polymorphism.

Abstract
Over the years, interleukin (IL)-27 has received much attention because of its highly divergent, sometimes even opposing, functions in immunity. IL-30, the p28 subunit that forms IL-27 together with Ebi3 and is also known as IL-27p28 or IL-27A, has been considered a surrogate to represent IL-27. However, it was later discovered that IL-30 can form complexes with other protein subunits, potentially leading to overlapping or discrete functions. Furthermore, there is emerging evidence that IL-30 itself may perform immunomodulatory functions independent of Ebi3 or other binding partners and that IL-30 production is strongly associated with certain cancers in humans. In this review, we will discuss the biology of IL-30 and other IL-30-associated cytokines and their functions in inflammation and cancer. Studying the ways that interleukin IL-30 regulates immune responses may provide novel insights into tumor development and inflammatory conditions. Interleukins are a diverse family of proteins involved in intercellular communications and immunity, where they can exert divergent and even opposing functions. Booki Min at Northwestern University in Chicago, USA, and co-workers reviewed the current understanding of IL-30 and its links to inflammation and cancer. IL-30 forms the IL-27 complex with the Ebi3 protein and was thought to be a surrogate for IL-27 in terms of activity. However, recent insights suggest that IL-30 may perform discrete immune modulation functions. Elevated IL-30 secretion is linked to prostate and breast cancer development. Extensive research is needed into the formation of IL-30, its associated protein interactions, and the development of a suitable animal model.

Analysis of genetically driven alternative splicing identifies FBXO38 as a novel COPD susceptibility gene. PLoS Genet 2019; 15:e1008229.

Abstract
While many disease-associated single nucleotide polymorphisms (SNPs) are associated with gene expression (expression quantitative trait loci, eQTLs), a large proportion of complex disease genome-wide association study (GWAS) variants are of unknown function. Some of these SNPs may contribute to disease by regulating gene splicing. Here, we investigate whether SNPs that are associated with alternative splicing (splice QTL or sQTL) can identify novel functions for existing GWAS variants or suggest new associated variants in chronic obstructive pulmonary disease (COPD). RNA sequencing was performed on whole blood from 376 subjects from the COPDGene Study. Using linear models, we identified 561,060 unique sQTL SNPs associated with 30,333 splice sites corresponding to 6,419 unique genes. Similarly, 708,928 unique eQTL SNPs involving 15,913 genes were detected at 10% FDR. While there is overlap between sQTLs and eQTLs, 55.3% of sQTLs are not eQTLs. Co-localization analysis revealed that 7 out of 21 loci associated with COPD (p<1x10-6) in a published GWAS have at least one shared causal variant between the GWAS and sQTL studies. Among the genes identified to have splice sites associated with top GWAS SNPs was FBXO38, in which a novel exon was discovered to be protective against COPD. Importantly, the sQTL in this locus was validated by qPCR in both blood and lung tissue, demonstrating that splice variants relevant to lung tissue can be identified in blood. Other identified genes included CDK11A and SULT1A2. Overall, these data indicate that analysis of alternative splicing can provide novel insights into disease mechanisms. In particular, we demonstrated that SNPs in a known COPD GWAS locus on chromosome 5q32 influence alternative splicing in the gene FBXO38.

Abstract
BACKGROUND While most studies focus on pro-allergic cytokines, the protective role of immunosuppressive cytokines in allergic inflammation is not well elucidated. This study was to explore a novel anti-inflammatory role and cellular/molecular mechanism of IL-27 in allergic inflammation. METHODS A murine model of experimental allergic conjunctivitis (EAC) was induced in BALB/c, C57BL/6 or IL-27Rα-deficient (WSX-1-/- ) mice by short ragweed pollen, with untreated or PBS-treated mice as controls. The serum, eyeballs, conjunctiva, cervical lymph nodes (CLNs) were used for study. Gene expression was determined by RT-qPCR, and protein production and activation were evaluated by immunostaining, ELISA and Western blotting. RESULTS Typical allergic manifestations and stimulated thymic stromal lymphopoietin (TSLP) signaling and Th2 responses were observed in ocular surface of EAC models in BALB/c and C57BL/6 mice. The decrease of IL-27 at mRNA (IL-27/EBI3) and protein levels were detected in serum, conjunctiva and CLN, as evaluated by RT-qPCR, immunofluorescent staining, ELISA and Western blotting. EAC induced in WSX-1-/- mice showed aggravated allergic signs with higher TSLP-driven Th2-dominant inflammation, accompanied by stimulated Th17 responses, including IL-17A, IL-17F, and transcription factor RORγt. In contrast, Th1 cytokine IFNγ and Treg marker IL-10, with their respective transcription factors T-bet and foxp3, were largely suppressed. Interestingly, imbalanced activation between reduced phosphor (P)-STAT1 and stimulated P-STAT6 were revealed in EAC, especially WSX-1-/- -EAC mice. CONCLUSION These findings demonstrated a natural protective mechanism by IL-27, of which signaling deficiency develops a Th17-type hyperresponse that further aggravates Th2-dominant allergic inflammation.

Interleukin 27 polymorphisms, their association with insulin resistance and their contribution to subclinical atherosclerosis. The GEA Mexican study. Cytokine 2018; 114:32-37. [PMID: 30594065 DOI: 10.1016/j.cyto.2018.11.028] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Revised: 11/05/2018] [Accepted: 11/26/2018] [Indexed: 12/19/2022]
Abstract
Our previous data suggest that the heterodimeric interleukin-27 (IL-27) could participate in the developing of insulin resistance (IR). Our aim was to assess the participation of IL-27p28 gene single nucleotide polymorphisms (SNPs) as markers for IR, subclinical atherosclerosis (SA) and cardiovascular risk factors in a Mexican population. Five IL-27p28 SNPs (rs153109, rs40837, rs17855750, rs26528 and rs181206) were genotyped in 856 individuals with IR and 644 participants without IR. Under inheritance models adjusted for confounding factors, the rs153109A (0.78[0.64-0.94] Padditive = 0.008, 0.58[0.41-0.82] Precessive = 0.002, 0.57[0.38-0.83] Pcodominant2 = 0.004), rs26528T (0.78[0.64-0.94] Padditive = 0.008, 0.61[0.43-0.88] Precessive = 0.007, 0.57[0.38-0.84] Pcodominant2 = 0.004) and rs40837A (0.76[0.63-0.92] Padditive = 0.004; 0.60[0.42-0.86] Precessive = 0.005; 0.54[0.37-0.80] Pcodominant2 = 0.002) alleles were related with a decreased risk of IR. Moreover, AAATA haplotype that contains the protector alleles was related with 17% lower risk of presenting IR (0.83 [0.71-0.98], P = 0.023). After adjusting for potential confounding variables, IL-27p28 SNPs were not associated with SA. However, some SNPs were associated with hypertension (rs26528 and rs40837) and increased total abdominal fat (rs17855750) in non-IR individuals, whereas in IR subjects we observed an association of rs26528 and rs40837 with hypoadiponectinemia. Our evidence suggests that rs40837A, rs153109A, and rs26528T alleles could be envisaged as protective markers for IR. Some polymorphisms showed an association with hypertension, low adiponectin levels, and increased total abdominal fat.

He J, Zhang Q, Zhang W, Chen F, Zhao T, Lin Y, Li J, Liu Y, Liu Y, Shao Y. The interleukin-27 -964A>G polymorphism enhances sepsis-induced inflammatory responses and confers susceptibility to the development of sepsis. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2018; 22:248. [PMID: 30268141 PMCID: PMC6164187 DOI: 10.1186/s13054-018-2180-0] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/25/2018] [Accepted: 09/05/2018] [Indexed: 02/03/2023]
Abstract
Background Previous studies have identified critical roles of IL-27 in the pathological mechanisms of sepsis, and blockade of IL-27 may be a promising alternative therapy for sepsis. The purpose of this study was to evaluate the clinical relevance of IL-27 genetic polymorphisms in sepsis and to further characterize their effect on IL-27 expression and inflammatory processes following sepsis. Methods A total of 885 septic patients and 1101 healthy controls were enrolled and genotyped for IL-27 genetic variants (rs153109/−964A > G and rs17855750/2905 T > G). Quantitative real-time PCR and enzyme-linked immunosorbent assays were performed to detect IL-27 expression and cytokine production. The effect of the rs153109 polymorphism on IL-27 promoter activity was evaluated using a luciferase reporter assay, and THP-1 cell apoptosis was calculated using an annexin V apoptosis assay. Results No significant differences in the genotype/allele frequencies were observed between patients with sepsis and healthy controls, suggesting that these two IL-27 polymorphisms may not influence susceptibility to sepsis. The -964AA genotype was overrepresented in patients with severe sepsis/septic shock relative to patients with the sepsis subtype, and the A allele was significantly associated with 28-mortality in sepsis. Patients carrying the -964AA genotype exhibited significantly higher expression levels of IL-27 than the GA/GG genotype carriers. The results of an in vitro (lipopolysaccharide (LPS))-stimulated experiment showed that this sepsis-associated high-risk AA genotype significantly increased IL-27 levels and enhanced TNF-α and IL-1β production in the peripheral blood mononuclear cells (PBMCs) upon exposure to LPS in vitro. Furthermore, luciferase reporter assays indicated that the high-risk -964A allele resulted in increased promoter activities compared to the non-risk allele in THP-1 and 293 T cells. Additionally, IL-27 treatment significantly enhanced TNF-α and IL-6 secretion and apoptosis of THP-1 cells upon LPS stimulation. Conclusions These results provided evidence that the IL-27 -964A > G polymorphism functionally enhanced IL-27 expression and promoted sepsis-induced inflammatory responses, which ultimately resulted in promoting the progression of sepsis and poor prognosis.

Biochim Biophys Acta Gen Subj 2018; 1862:1069-1078. [PMID: 29410184 DOI: 10.1016/j.bbagen.2018.01.020] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2017] [Revised: 01/18/2018] [Accepted: 01/31/2018] [Indexed: 11/16/2022]
Abstract
BACKGROUND Interleukin-6 is a gp130 utilizing cytokine that is consistently associated with allergic diseases like asthma and urticaria in humans where mast cells are known to play a critical role. However, the role of IL-6 in allergic disease in not known. IL-6 was reported to enhance degranulation of in vitro-derived mast cells, but the effect of IL-6 on mediator release from human in situ-matured tissue-isolated mast cells had not been reported. METHODS Human mature mast cells were isolated and purified from normal skin tissue from different donors. The expression of surface-expressed IL-6 receptors was demonstrated by flow cytometry. The effect of IL-6 on FcεRI-induced degranulation, PGD2 biosynthesis, and cytokine production was determined with β‑hexosaminidase release assay, Western blotting, quantitative real-time PCR, and ELISA. The small molecule inhibitor of STAT-3, C188-9, was used to demonstrate STAT3 dependency. RESULTS IL-6 significantly potentiated FcεRI-induced PGD2 biosynthesis, but had no effect on degranulation. IL-6 also induced VEGF gene expression and protein secretion, and enhanced FcεRI-induced IL-8 production. Mechanistically, IL-6 enhanced FcεRI-induced COX‑2 expression, PGD2 biosynthesis, and VEGF production in a STAT3 dependent manner. CONCLUSION Here, we demonstrate that IL-6 is a potentiator of FcεRI-induced PGD2 biosynthesis, and can induce or enhance production of pro-angiogenesis factors VEGF and IL-8 from human in situ-matured skin mast cells. GENERAL SIGNIFICANCE These findings from this study indicate that IL-6 contributes to human allergic disease by enhancing the production of inflammatory PGD2 from tissue-resident mast cells. Moreover, the data suggest a novel role for IL-6 in mast cell-mediated angiogenesis.

Critical Role of Plasmacytoid Dendritic Cells in Regulating Gene Expression and Innate Immune Responses to Human Rhinovirus-16. Front Immunol 2017; 8:1351.

Abstract
Though human rhinoviruses (HRVs) are usually innocuous viruses, they can trigger serious consequences in certain individuals, especially in the setting of impaired interferon (IFN) synthesis. Plasmacytoid dendritic cells (pDCs) are key IFN producing cells, though we know little about the role of pDC in HRV-induced immune responses. Herein, we used gene expression microarrays to examine HRV-activated peripheral blood mononuclear cells (PBMCs) from healthy people, in combination with pDC depletion, to assess whether observed gene expression patterns were pDC dependent. As expected, pDC depletion led to a major reduction in IFN-α release. This was associated with profound differences in gene expression between intact PBMC and pDC-depleted PBMC, and major changes in upstream regulators: 70–80% of the HRV activated genes appeared to be pDC dependent. Real-time PCR confirmed key changes in gene expression, in which the following selected genes were shown to be highly pDC dependent: the transcription factor IRF7, both IL-27 chains (IL-27p28 and EBI3), the alpha chain of the IL-15 receptor (IL-15RA) and the IFN-related gene IFI27. HRV-induced IL-6, IFN-γ, and IL-27 protein synthesis were also highly pDC dependent. Supplementing pDC-depleted cultures with recombinant IL-15, IFN-γ, IL-27, or IL-6 was able to restore the IFN-α response, thereby compensating for the absence of pDC. Though pDC comprise only a minority population of migratory leukocytes, our findings highlight the profound extent to which these cells contribute to the immune response to HRV.

Abstract
BACKGROUND The pathogenesis of severe asthma in childhood remains poorly understood. OBJECTIVE We sought to construct the immunologic landscape in the airways of children with severe asthma. METHODS Comprehensive analysis of multiple cell types and mediators was performed by using flow cytometry and a multiplex assay with bronchoalveolar lavage (BAL) specimens (n = 68) from 52 highly characterized allergic and nonallergic children (0.5-17 years) with severe treatment-refractory asthma. Multiple relationships were tested by using linear mixed-effects modeling. RESULTS Memory CCR5+ TH1 cells were enriched in BAL fluid versus blood, and pathogenic respiratory viruses and bacteria were readily detected. IFN-γ+IL-17+ and IFN-γ-IL-17+ subsets constituted secondary TH types, and BAL fluid CD8+ T cells were almost exclusively IFN-γ+. The TH17-associated mediators IL-23 and macrophage inflammatory protein 3α/CCL20 were highly expressed. Despite low TH2 numbers, TH2 cytokines were detected, and TH2 skewing correlated with total IgE levels. Type 2 innate lymphoid cells and basophils were scarce in BAL fluid. Levels of IL-5, IL-33, and IL-28A/IFN-λ2 were increased in multisensitized children and correlated with IgE levels to dust mite, ryegrass, and fungi but not cat, ragweed, or food sources. Additionally, levels of IL-5, but no other cytokine, increased with age and correlated with eosinophil numbers in BAL fluid and blood. Both plasmacytoid and IgE+FcεRI+ myeloid dendritic cells were present in BAL fluid. CONCLUSIONS The lower airways of children with severe asthma display a dominant TH1 signature and atypical cytokine profiles that link to allergic status. Our findings deviate from established paradigms and warrant further assessment of the pathogenicity of TH1 cells in patients with severe asthma.

Abstract
Several studies suggest an important role of Interleukin-27 in the development of atherosclerosis. The aim of this study was to establish whether the IL-27p28 gene polymorphisms are associated with premature coronary artery disease and/or other cardiovascular risk factors. Four IL-27p28 gene polymorphisms were selected and genotyped in 1162 premature coronary artery disease cases and 1107 controls. rs26528 T and rs40837 A alleles were significantly associated with a lower risk of premature coronary artery disease under different inheritance models (Pdominant = 0.046; Pover-dominant = 0.002; Pco-dominant1 = 0.007 for rs26528T; Pover-dominant = 0.008 and Pco-dominant1 = 0.031 for rs40837). The rs40837 A allele was also associated with a lower risk of insulin resistance, in cases (Pover-dominant = 0.037) and controls (Padditive = 0.008; Pdominant = 0.047; Precessive = 0.014; Pco-dominant2 = 0.006), while the rs26528 T allele was associated with a lower risk of insulin resistance only in the control group (Precessive = 0.016; Pco-dominant2 = 0.021). Interleukin-27 plasma levels were measured in 450 controls and 450 cases, and were significantly higher in cases compared to controls (P = 0.004). However, Interleukin-27 plasma levels were not associated with IL-27p28 polymorphisms. Luciferase assays showed that co-transfection of the rs40837 A allele and miR-379-5p significantly decreased luciferase gene expression. Our study shows for the first time, that IL-27p28 gene polymorphisms are associated with premature coronary artery disease and with some metabolic parameters. The rs40837 A allele in presence of miR-379-5p significantly decreased luciferase gene expression.

Abstract
Interleukin (IL)-27 is a cytokine with important anti-cancer activity. This study has evaluated the effects of IL-27 rs153109 and rs17855750 single nucleotide polymorphisms (SNPs) on risk of acute lymphoblastic leukemia (ALL) development, as well as their impact on prognosis and patient survival. A total of 200 patients and 210 healthy subjects were genotyped by polymerase chain reaction-restriction fragment length polymorphism. We observed a higher frequency of rs153109 AG and rs17855750 TG genotypes and allele G in patients compared to controls (p < 0.001). Combined G variant genotypes (AG + GG and TG + GG) also conferred significantly greater risk of ALL. There was a significant correlation between the genotypes of both SNPs with event-free survival (EFS). Patients with GG genotypes of both SNPs and those of rs153109 AG and rs17855750 TG had a shorter EFS than patients with rs153109 AA and rs17855750 TT genotypes (p ≤ 0.035). Combined G variant genotypes for both SNPs showed poorer response to therapy in all patients (p < 0.027) as well as B-ALL (rs153109, p < 0.001) and T-ALL (rs153109, p = 0.048) patients. In multivariate analysis, rs153109 combined G variant genotype was associated with shorter EFS (relative risk = 9.7, p = 0.026). Among those who relapsed, 87.1% had the rs153109 AG genotype and 77.4% had the rs17855750 TG genotype (p < 0.01). Patients had higher IL-27 serum levels compared to controls, but this did not differ between genotypes. In conclusion, the association of IL-27 rs153109 and rs17855750 polymorphisms with risk of ALL development and their impact on EFS suggested an important role for this cytokine in biology and response to ALL therapy.

Abstract
IL-27 plays an important role in anti-cancer activity. The -964A/G polymorphism in IL-27 gene has been implicated in susceptibility to cancer, but the results were conflicting. The aim of this study was to assess the association between this polymorphism and cancer risk. Pubmed and Wanfang database were searched for all publications concerning IL-27 -964A/G polymorphism and cancer risk. Odds ratio (OR) and 95% confidence interval (CI) were used to assess the strength of association. Statistical analysis was performed using Stata 11.0 software. A total of eight case-control studies including 2044 cancer cases and 2197 controls were identified. Overall, significant association between IL-27 -964A/G polymorphism and cancer risk was observed (GG versus AA: OR = 1.26, 95% CI = 1.03-1.52; GG versus AG + AA: OR = 1.20, 95% CI = 1.00-1.44). In subgroup analysis based on cancer type, significant association was found in colorectal cancer (GG versus AA: OR = 1.55, 95% CI = 1.07-2.27; AG versus AA: OR = 1.31, 95% CI = 1.02-1.67). The current meta-analysis suggests that IL-27 -964A/G polymorphism might enhance cancer risk. However, large-scale and well-designed studies are still needed to confirm the result of our meta-analysis. The association of IL-27 polymorphism with colorectal cancer may provide insight for future therapies.

Abstract
To investigate the potential association between IL-12B and IL-27 gene polymorphisms and systemic lupus erythematosus (SLE), we performed a case-control study based on the Polish population. Patients with SLE and healthy individuals were examined for -6415 CTCTAA/GC (rs17860508) and +1188A/C (rs3212227) in IL-12B and -924A/G (rs153109) and 4730T/C (rs181206) in IL-27 gene polymorphisms using the high-resolution melting method, PCR-RFLP method and TaqMan SNP genotyping assay, respectively. An increased frequency of GC/GC genotype as well as GC allele of the IL-12B rs17860508 was found in patients with SLE, as compared with healthy subjects (P < 0.001). We did not find differences in genotype and allele frequencies of the IL-12B rs3212227 and IL-27 rs153109 and rs181206 variants between patients with SLE and controls. IL-27 haplotype rs181206C/rs153109G indicated higher risk for SLE (P = 0.002), whereas haplotype rs181206T/rs153109G indicated reduced risk for SLE (P = 0.005). The IL-12B rs3212227 A/C polymorphism was associated with the mean value of the platelets (PLT), urea and complement C3 level. Furthermore, IL-12B rs17860508 genetic variant showed correlation with PLT, prothrombin time, international normalized ratio and alkaline phosphatase. Our results revealed that IL-12B rs17860508 and IL-27 haplotype CG are genetic risk factors for SLE and that both IL-12B rs17860508 and rs3212227 predict disease phenotype.

IL-27 Limits Type 2 Immunopathology Following Parainfluenza Virus Infection. PLoS Pathog 2017; 13:e1006173.

Abstract
Respiratory paramyxoviruses are important causes of morbidity and mortality, particularly of infants and the elderly. In humans, a T helper (Th)2-biased immune response to these infections is associated with increased disease severity; however, little is known about the endogenous regulators of these responses that may be manipulated to ameliorate pathology. IL-27, a cytokine that regulates Th2 responses, is produced in the lungs during parainfluenza infection, but its role in disease pathogenesis is unknown. To determine whether IL-27 limits the development of pathogenic Th2 responses during paramyxovirus infection, IL-27-deficient or control mice were infected with the murine parainfluenza virus Sendai virus (SeV). Infected IL-27-deficient mice experienced increased weight loss, more severe lung lesions, and decreased survival compared to controls. IL-27 deficiency led to increased pulmonary eosinophils, alternatively activated macrophages (AAMs), and the emergence of Th2 responses. In control mice, IL-27 induced a population of IFN-γ+/IL-10+ CD4+ T cells that was replaced by IFN-γ+/IL-17+ and IFN-γ+/IL-13+ CD4+ T cells in IL-27-deficient mice. CD4+ T cell depletion in IL-27-deficient mice attenuated weight loss and decreased AAMs. Elimination of STAT6 signaling in IL-27-deficient mice reduced Th2 responses and decreased disease severity. These data indicate that endogenous IL-27 limits pathology during parainfluenza virus infection by regulating the quality of CD4+ T cell responses and therefore may have therapeutic potential in paramyxovirus infections.

Abstract
Enterovirus 71 (EV71) is a major pathogen for severe hand, foot, and mouth disease (HFMD), which leads to severe neurological complications and has high morbidity and mortality. Reliable biomarker for the prediction of deterioration in EV71-infected children with central nervous system (CNS) involvement may reduce the cardiopulmonary failure and mortality. Here, we found that serum IL-27 levels were significantly higher in stage III EV71-infected HFMD patients with early cardiopulmonary failure and strong correlation with CRP levels. IL27p28 polymorphisms (rs153109, rs17855750, and rs181206) did not influence IL-27 production, and these three SNPs were not associated with EV71 infection risk and clinical stage. IL-27 can be used as an prediction indicator for early cardiopulmonary failure in EV71-infected children with CNS involvement.

Abstract
Interleukin-27 (IL-27) is an important cytokine in inflammatory diseases, including coronary artery disease (CAD). To explore the precise role of IL-27 in CAD, we investigated the genetic association between IL27 and CAD in the GeneID Chinese Han population. A two-stage case control association analysis was performed for 3075 CAD cases and 2802 controls. Logistic regression analysis was used to adjust the traditional risk factors for CAD. Results showed that a promoter variant, rs153109, tended to be marginally associated with CAD in the discovery population (Padj = 0.028, OR = 1.27, 95%CI: 1.03–1.58). However, this association was not replicated in the validation stage (Padj = 0.559, OR = 1.04, 95%CI: 0.90–1.21). In addition, when we classified the combined population into two subgroups according to the age at disease onset or disease state, we again obtained no significant associations. Finally, we estimated the severity of coronary stenosis using the Gensini Scoring system and determined that the rs153109 genotypes were still not associated with the Gensini scores of the CAD patients. In conclusion, our study failed to find an association between common variants in the functional region of IL27 and CAD in a Chinese Han population, which indicated that IL-27 might only be an inflammatory marker during the development of CAD.

Abstract
OBJECTIVE To investigate the effect of Guben-fangxiao decoction (GBFXD) on respiratory-syncytial-virus (RSV)-induced asthma and the expression of asthma susceptibility gene, orosomucoid 1-like protein 3 (ORMDL3) in mice. METHODS Seventy-two female BALB/c mice were randomly assigned to normal, model, GBFXD high dose, GBFXD moderate dose, GBFXD low dose and montelukast groups. An asthma model was induced via intraperitoneal injection and aerosol inhalation of ovalbumin (OVA) and repeated intranasal instillation of RSV in all mice, except those in the normal group. All treatments were administered at the first onset of asthma (within 8 weeks of model establishment) and the mice were euthanized after 28 days of treatment. The levels of transforming growth factor-β (TGF-β) and interleukin-6 (IL-6) in bronchoalveolar lavacie fluid (BALF) of the mice were measured and the expression of asthma susceptibility gene ORMDL3 in lung tissue was determined using real-time polymerase chain reaction (RT-PCR) and western blotting. RESULTS Expression of ORMDL3 and levels of TGF-β and IL-6 were significantly higher in the model group (P < 0.05, P < 0.01) compared with the normal mice. Levels of ORMDL3, TGF-β and IL-6 were significantly lower in all three GBFXD treated groups (P < 0.05) compared with the model group. However, the levels in the GBFXD treatment groups did not differ significantly from the montelukast group. CONCLUSION GBFXD had a therapeutic effect in this experimental model. The functional mechanism of GBFXD may involve multiple factors, including alleviation of airway inflammation, down-regulation of asthma susceptibility gene ORMDL3 and inhibition of airway remodeling.

Abstract
IL-27 could inhibit the development of Th17 cells, and the Th17/regulatory T-cell imbalance may reverse maternal tolerance in pre-eclampsia (PE). The aim of this study was to investigate the association between genetic polymorphisms in IL27 with PE. Three SNPs in IL27 (rs153109, rs17855750, and rs181206) were genotyped in a Chinese Han cohort of 1040 PE patients and 1247 normal pregnant women using the TaqMan allelic discrimination real-time PCR method. The CC genotypic distribution of rs153109 was significantly higher among cases than controls (19.1% versus 13.3%, odds ratio [OR]: 1.54, 95% confidence interval [CI]: 1.23-1.93, p < 0.001), and the CT genotype was found to be significantly lower in cases than controls (41.7% versus 49.0%, OR: 0.74, 95% CI: 0.63-0.88, p < 0.001), disputing existing reports indicating the allele frequency of rs153109 is not significantly different between PE patients and controls. Additionally, the CC genotype of rs153109 was significantly more prevalent in PE cases than controls using a recessive model (p < 0.001). The allelic and genotypic frequencies of rs17855750 and rs181206 were not significantly different between two groups. Our results reveal that IL27 polymorphisms may be involved in the development of PE in Chinese Han population.

Abstract
Background Genetic variations in the IL-27 gene have been proven to be associated with various types of human cancers and diseases. The purpose of the current study was to clarify the associations of the IL-27 rs153109 A>G and rs181206 T>C variants with human diseases using a meta-analysis study. Material/Methods A comprehensive electronic and manual search was carried out to find potential eligible studies. The effect size was represented by the unadjusted odds ratios (ORs). A 95% confidence interval (95%CI) was tested for the pooled OR using the Z test. Results A total of 17 case-control studies (cases=4185, healthy controls=4077) were included in our study. Our study showed that the carriers of the rs181206 T>C and rs153109 A>G polymorphism in the IL-27 gene have elevated risks of diseases in the allele model (rs181206 T>C: OR=0.76, 95%CI=0.69~0.84, P<0.001; rs153109 A>G: OR=0.85, 95%CI=0.76~0.94, P=0.002) and dominant model (rs181206 T>C: OR=0.77, 95%CI=0.69~0.87, P<0.001; rs153109 A>G: OR=0.84, 95%CI=0.71~0.99, P=0.033). Disease type-stratified subgroup analysis yielded increased risk of related diseases in IL-27 rs181206 T>C carriers in the allele model in immune thrombocytopenia (ITP), asthma, and esophageal cancer (EC) subgroups (ITP: OR=0.69, 95%CI=0.53~0.88, P=0.004; asthma: OR=0.60, 95%CI=0.41~0.89, P=0.010; EC: OR=0.79, 95%CI=0.64~0.97, P=0.026); and IL-27 rs153109 A>G polymorphism was remarkably associated with the increased risk of related diseases in the allele model in ovarian cancer (OC), systemic lupus erythematosus (SLE), tuberculosis (TB), ulcerative colitis (UC), and chronic obstructive pulmonary disease (COPD) subgroups (all P<0.05). Conclusions Our results indicate that the genetic polymorphisms of IL-27 rs153109 and rs181206 may be involved in the progression of human cancers and diseases, especially of TB, UC, COPD, OC, and ITP.

Abstract
Ulcerative colitis (UC) is a chronic condition of unknown etiology and a polygenic disease. The interleukin 27 (IL-27) have been implicated in the pathogenesis of several autoimmune diseases including inflammatory bowel disease. Several polymorphisms of IL-27 have been associated with several types of cancer and immune disorders. The aim of the present study was to evaluate the association between IL-27 gene polymorphisms and the development of UC. Four polymorphisms of IL-27p28 gene (rs181206, rs26528, rs17855750, and rs40837) and three of the Epstein-Barr virus-induced gene 3 (EBI3) (rs428253, rs4740, and rs4905) were genotyped by 5' exonuclease TaqMan genotyping assays on an ABI Prism 7900HT Fast Real-Time PCR System in 375 Mexican patients with UC and 1599 Mexican Mestizo healthy unrelated individuals. IL-27 levels were determined in 458 healthy controls. Under recessive model adjusted by age and gender, the IL-27p28 rs17855750 polymorphism was associated with decreased risk of developing UC (OR=0.27, 95% CI: 0.06-1.13, P=0.031). On the other hand, under recessive models adjusted by age and gender, the EBI3 rs428253 (OR=0.54, 95% CI: 0.29-0.99, P=0.035), rs4740 (OR=0.60, 95% CI: 0.36-1.01, P=0.046) and rs4905 (OR=0.59, 95% CI: 0.35-1.01, P=0.043) were associated with decreased risk of developing UC. Similar levels of IL-27 were observed among the genotypes of the studied polymorphisms. IL-27 polymorphisms might play a protective role for the development of UC in the Mexican population.

Abstract
BACKGROUND Interleukin-27 (IL-27) has been recognized as a pleiotropic cytokine with both pro- and anti-inflammatory properties. PATIENTS AND METHODS A case-control study was conducted to investigate the possible associations of IL-27 gene polymorphisms with susceptibility to cervical cancer and clinical outcome. RESULTS Our results suggested that the IL-27 2905T/G was significantly associated with a decreased risk of cervical cancer. Further analysis showed IL-27 2905T/G genotypes were associated with advanced tumor stages of cervical cancer patients. More interestingly, the IL-27 2905T/G genotypes were statistically significantly associated with the survival in cervical cancer patients. CONCLUSION Our results showed that the IL-27 2905T/G genotypes were associated with decreased the susceptibility and development of cervical cancer in Chinese Han population.

Abstract
BACKGROUND HCV is a major global health problem. IL-27 is a member of the IL-6/IL-12 cytokine family with a broad range of anti-inflammatory properties. Recent studies highlighted the effect of a SNP in the IL-27 promoter region on modulating the progression of infectious diseases and individual responses to therapy. AIM OF THE WORK The present study investigated the potential role of (-964 A/G) SNP in the promoter region of IL-27p28 gene (alleles rs153109) on the outcome of HCV infection among genotype 4a infected patients. MATERIALS AND METHODS HCV genotyping confirmed that all of the HCV-infected patients had genotype 4a infection. Genomic DNA was extracted from 111 patients with chronic HCV infection, 42 spontaneous resolvers (SR) and 16 healthy controls. IL- 27p28.rs153109 genotyping was assessed using PCR-RFLP then confirmed by DNA sequencing. RESULTS The frequency of IL-27-p28.rs153109AA, AG, and GG genotypes among chronically infected subjects were 74.8 %, 25.2%, and 0% while among the SR, they were 57.1%, 35.7%, and 7.14%, respectively. Our data show the unique presence of G/G genotype in the SR group (3 patients; 7.14%). Moreover, the "G" allele frequencies among chronic and resolved subjects were 12.6% and 25.0%, respectively (p=0.0136). Importantly, subjects with the GG genotype were more likely to clear their HCV infection than those with the AA genotype (p=0.0118). CONCLUSIONS HCV genotype 4a subjects with the IL-27-p28.rs153109 A/G and G/G genotype were more likely to clear their HCV infection. Therefore, we propose IL- 27p28.rs153109SNPas a genetic biomarker for predicting HCV infection outcome.

Interleukin-27 (IL-27) has been recognized as a pleiotropic cytokine with both pro- and anti-inflammatory properties. However, there are no data about the role of IL-27 polymorphism in the development of cervical cancer. A hospital-based case-control study was conducted in 380 patients with cervical cancer and 380 healthy controls to investigate the possible associations of IL-27 gene polymorphisms (-964A/G, 2905T/G, and 4730T/C), with susceptibility to cervical cancer and clinical outcome. Our results suggested that the IL-27 2905T/G was significantly associated with a decreased risk of cervical cancer (TG vs. TT, odds ratio (OR) = 0.77; 95 % confidence interval (CI) = 0.60-0.86; GG vs. TT, OR = 0.95; 95 % CI = 0.72-0.96; TG+GG vs. TT, OR = 0.87; 95 % CI = 0.65-0.94). However, the genotype and allele frequencies of IL-27 (-964A/G and 4730T/C) polymorphisms in cervical cancer patients were not significantly different from controls. Further analysis showed IL-27 2905T/G genotypes were associated with advanced tumor stages of cervical cancer patients. More interestingly, the IL-27 2905T/G genotypes were statistically significantly associated with the survival in cervical cancer patients. Our results showed that the IL-27 2905T/G genotypes were associated with decreased susceptibility and development of cervical cancer in Chinese Han population.

Abstract
IL-27, a new member of the IL-12 family, has been found to have antitumor effects in colorectal cancer (CRC); therefore, polymorphisms of this protein may modulate CRC carcinogenesis. So, we studied the association of single nucleotide polymorphisms of the IL-27 gene with the risk of CRC occurrence using a case–control using 600 CRC patients and matched healthy controls. The IL-27 rs153109 polymorphism was analyzed with polymerase chain reaction-restriction fragment length polymorphism and DNA sequencing methods. Data indicate that GG, GA, and combined A-variant genotypes (GG + GA) conferred significantly greater risk of CRC (P=0.034, 0.002, and 0.001, respectively), and that G alleles were associated with higher susceptibility to CRC (P=0.001). However, no correlation was found between the IL-27 rs153109 polymorphism and particular clinical features. In conclusion, our data demonstrated a clear association of IL-27 rs153109 polymorphism and the risk of CRC development.

Abstract
Background Interleukin-27 (IL-27) has been recognized as a pleiotropic cytokine with both pro- and anti-inflammatory properties. Few studies have investigated polymorphisms and serum/plasma levels of IL-27 in diseases including cancers. This study has analyzed the associations of IL-27 gene polymorphisms, as well as plasma levels of IL-27, with susceptibility to bladder cancer and clinical outcome. Methods Three hundred and thirty-two patients (nonmuscle-invasive bladder cancer (NMIBC)/muscle-invasive bladder cancer (MIBC): 176/156) included in a 60-month follow-up program and 499 controls were enrolled. Two single nucleotide polymorphisms (SNPs), rs153109 and rs17855750, were genotyped by polymerase chain reaction (PCR) -restriction fragment length polymorphism (RFLP) method. Plasma concentration of IL-27 was determined by ELISA in 124 patients (NMIBC/MIBC: 50/74) and 151 controls. Results Significantly increased risk for bladder cancer was associated with AG/GG genotypes of rs153109 (P = 0.029). No GG genotype of rs17855750 was observed in controls, while 4 patients were found to be GG homozygotes, suggesting GG genotype may be associated with bladder cancer risk (P = 0.006). For bladder cancer patients, SNP rs17855750 was also associated with increased risk for MIBC. For MIBC patients, but not NMIBC, TG/GG genotypes of rs17855750 turned out to be a protective factor for overall survival (P = 0.035). Significantly reduced plasma levels of IL-27 were observed in both NMIBC and MIBC patients compared with controls (P < 0.0001). Conclusion Our data suggest that polymorphisms and reduced plasma levels of IL-27 may predict the susceptibility to bladder cancer, and rs17855750 may be a useful marker to distinguish patients with high risk of death.

Abstract
IL-27, a heterodimeric cytokine of IL-12 family, regulates both innate and adaptive immunity largely via Jak-Stat signaling. IL-27 can induce IFN-γ and inflammatory mediators from T lymphocytes and innate immune cells. IL-27 has unique anti-inflammatory properties via both Tr1 cells dependent and independent mechanisms. Here the role and biology of IL-27 in innate and adaptive immunity are summarized, with special interest with immunity against Mycobacterium tuberculosis.

Abstract
Rheumatoid arthritis (RA) is one of the autoimmune diseases, where different polymorphisms in cytokine genes play a pathogenic role. Interleukin 27 (IL-27) is a novel pro-/anti-inflammatory cytokine, an excellent candidate for chronic inflammatory disease studies. The aim of the study was to identify polymorphisms in the IL-27 gene and their possible association with susceptibility to and severity of RA. Two hundred and seventy-four patients with RA and of 295 healthy individuals were examined for -924A/G and 4730T/C IL27 gene polymorphisms using PCR-RFLP method and TaqMan SNP genotyping assay, respectively. Haplotype frequencies of IL-27 polymorphisms were estimated using SHEsis platform. Frequencies of the -924GG genotype and the -924G allele were statistically higher in RA patients comparing with the healthy control group (P = 0.008 and P = 0.004, respectively). Overall, strong LD was observed between the IL27 gene -924A/G and 4730 T/C polymorphisms (D' = 0.613, r2 = 0.199). From four possible haplotypes, frequencies of two (CA and CG) showed significant differences between both examined groups (respectively: P < 0.001 and P = 0.001062). The genotype-phenotype analysis showed significant association between the IL-27 4730 T/C polymorphism and HAQ score and means value of the ESR, additionally they revealed that individuals with the polymorphic allele -924G had more advanced disease than wild-type allele carriers. Present findings indicated that IL27 -924A/G polymorphism may be involved in susceptibility to RA in the Polish population.

IL-27 and type 2 immunity in asthmatic patients: association with severity, CXCL9, and signal transducer and activator of transcription signaling. J Allergy Clin Immunol 2014; 135:386-94.

Abstract
BACKGROUND Severe asthma (SA) can involve both innate and type 2 cytokine-associated adaptive immunity. Although IL-27 has been reported to potentiate TH1 responses (including the chemokine CXCL9) and suppress TH2 responses, its function in asthmatic patients is unknown. OBJECTIVE We sought to evaluate IL-27 expression in human asthma alone and in combination with type 2 immunity to determine the relationship to disease severity and CXCL9 expression. We also sought to model these interactions in vitro in human bronchial epithelial cells. METHODS Bronchoalveolar lavage cells from 87 participants were evaluated for IL-27 mRNA and protein alone and in association with epithelial CCL26 (a marker of type 2 activation) in relation to asthma severity and CXCL9 mRNA. Human bronchial epithelial cells cultured at the air-liquid interface and stimulated with IL-27 (1-100 ng/mL) with or without IL-13 (1 ng/mL) were evaluated for CXCL9 expression by using quantitative real-time PCR and ELISA. Phosphorylated and total signal transducer and activator of transcription (STAT) 1/3 were detected by means of Western blotting. Small interfering RNA knockdown of STAT1 or STAT3 was performed. RESULTS Bronchoalveolar lavage cell IL-27 mRNA and protein levels were increased in asthmatic patients. Patients with evidence for type 2 pathway activation had higher IL-27 expression (P = .02). Combined IL-27 and CCL26 expression associated with more SA and higher CXCL9 expression (P = .004 and P = .007 respectively), whereas IL-27 alone was associated with milder disease. In vitro IL-13 augmented IL-27-induced CXCL9 expression, which appeared to be due to augmented STAT1 activation and reduced STAT3 activation. CONCLUSIONS IL-27, in combination with a type 2/CCL26 signature, identifies a more SA phenotype, perhaps through combined effects of IL-27 and IL-13 on STAT signaling. Understanding these interactions could lead to new targets for asthma therapy.

Abstract
Background Interleukin 27 (IL-27) has pleiotropic properties that can either limit or enhance immune responses. Recent studies revealed that single nucleotide polymorphisms (SNPs) of the IL-27 promoter region modulate the development of infectious diseases and individual's susceptibility to therapeutic response. Little is known about the relationship between IL-27 single nucleotide polymorphisms and therapy response in patients infected by hepatitis C virus (HCV). In this study we have investigated the potential role of SNPs in the promoter region of IL27 p28 gene (alleles rs153109) on the outcome of HCV infected patients. Methods rs153109, corresponding to position c.-964A>G of the IL-27 locus, was amplified from genomic DNA extracted from 15 patients with chronic hepatitis C stratified by sustained viral response (SVR), relapser and non-responder, after treatment with peginterferon-α (PegIFN- α) combined with ribavirin (RBV). Amplification products were studied by direct sequencing. Results This method has been applied in a preliminary study on patients with chronic hepatitis C to provide information for a standardized assay useful to genotyping of rs153109 SNPs of IL-27p28. The genotype distribution of the c.-964 A>G polymorphism was more present in patients who did not achieve a SVR. By contrast, the genotype G/G was absent in non-responder and relapser patients. Moreover, the analysis of allelic distribution of rs153109 highlighted a predominance of allele A in all genotypes in spite of allele G. Conclusions Our work provides preliminary information for a standardized method potentially useful for genotyping rs153109, and suggests its utility as a candidate approach to evaluate IL-27 p28 polymorphisms as additional clinical predictors of response to therapies in HCV infected patients.

Abstract
Interleukin-27 (IL-27) is a new member of the IL-12 family which plays a key role in antitumor immunity. The aim of the present study was to investigate the association between a potentially functional polymorphism (rs153109, -964A>G) at the promoter of IL-27 and the risk of breast cancer in a Chinese population. We determined the genotypes of 326 breast cancer cases and 460 healthy controls by using polymerase chain reaction-restriction fragment length polymorphism analysis. Logistic regression was used to analyze the association between -964A>G polymorphism and breast cancer susceptibility. There was no significant association between IL-27 -964A>G polymorphism and the risk of breast cancer. However, in the stratified analysis by menopausal history, IL-27 -964A>G polymorphism was associated with a decreased risk of breast cancer in premenopausal women (GG vs. AA: OR = 0.48, 95 % CI = 0.26-0.89; G vs. A: OR = 0.75, 95 % CI = 0.59-0.97). Taken together, our study suggested that IL-27 -964A>G polymorphism may be a protective factor for breast cancer in premenopausal women.

Abstract
Interleukin (IL)-27 is a novel cytokine secreted by stimulation of antigen-presenting cells. No previous studies currently reported the role of IL-27 in the carcinogenesis of osteosarcoma. We aimed to investigate the association of IL-27 polymorphisms and serum IL-27p28 with osteosarcoma risk in a Chinese population.One hundred and sixty osteosarcoma patients and 250 health controls were selected. IL-27 gene -964 A/G, 2905 T/G, and 4730 T/C polymorphisms were determined by using polymerase chain reaction-restriction fragment length polymorphism. Enzyme-linked immunosorbent assay were used to detect serum IL-27p28 levels.The serum IL-27p28 levels were significantly lower in osteosarcoma patients compared with those in controls (P < 0.01). Serum IL-27p28 levels in stages III-IV were lower than those in stages I-II of osteosarcoma (P < 0.05); similar results were also found in patients with metastasis, that is, patients with metastasis have higher IL-27p28 levels than those without metastasis (P < 0.05). There were no associations between genotype and allele frequencies of IL-27 -964 A/G, 2905 T/G, 4730 T/C, and the risk of osteosarcoma (P > 0.05). Stratification analysis also failed to show the associations between -964 A/G, 2905 T/G, and 4730 T/C polymorphisms and the clinical stage and metastasis of osteosarcoma (P > 0.05). Three possible haplotypes (ATT, GTT, and GGC) were identified, but no associations were found between them and the osteosarcoma risk (P > 0.05).This study indicates that the lower serum IL-27p28 levels may be associated with development and progression of osteosarcoma, but IL-27 gene -964 A/G, 2905 T/G, and 4730 T/C polymorphisms and their haplotypes are not associated with osteosarcoma risk.

Abstract
OBJECTIVES Allergic rhinitis (AR) is an inflammatory disorder of the upper airway. Interleukin-27 (IL-27), a novel IL-12 family member, has recently been reported to play a role in some immune-related disorders. This study was performed to evaluate the potential association of IL-27 polymorphisms with AR in a Chinese Han population. DESIGN AND METHODS A case-control study was performed in 445 Chinese AR patients and 691 healthy controls. Three SNPs in the IL-27p28 gene, including rs153109, rs17855750 and rs181206, were detected using a polymerase chain reaction-restriction fragment length polymorphism assay (PCR-RFLP). RESULTS A significantly increased prevalence of the rs153109 TT genotype and the T allele was found in AR patients, while a decreased prevalence of the CT and CC genotypes and the C allele was found. For rs153109, the TT genotype and the T allele were significantly associated with the risk of AR, but the CT and CC genotypes and the C allele decreased the risk of AR; for rs17855750, the TT genotype and T allele were risk factors for AR, and the GT genotype and G allele provided protection. TTT and TTC haplotypes in the IL-27p28 gene were positively correlated with AR, while CGT, CTC and CTT haplotypes were associated with a significantly decreased risk of AR. CONCLUSION This study indicates that IL-27p28 polymorphisms rs153109 and rs17855750 are likely involved in AR susceptibility, making them potentially useful genetic biomarkers for AR susceptibility in the Chinese Han population.

Abstract
IL-27 is a cytokine of the IL-12 family that plays a key role in the regulation of inflammatory and T cell responses. Its receptor is composed of IL-27Rα and gp130 and activates the STAT pathway. We show in this study, using an ELISA that we developed, that a naturally occurring soluble form of IL-27Rα (sIL-27Rα) is produced by human activated CD4(+) and CD8(+) T cells, B cells, myeloid cells, and various cell lines. sIL-27Rα is present at a mean concentration of 10,344 ± 1,274 pg/ml in the sera from healthy individuals. Biochemical studies showed that sIL-27Rα is released as two N-glycosylated variants of ∼ 90 and ∼ 70 kDa. In IL-27Rα-transfected COS7 cells, primary cells, and cell lines, production of sIL-27Rα is inhibited by the metalloprotease inhibitors GM6001 and TAPI-0. Importantly, natural sIL-27Rα binds rIL-27, inhibits IL-27 binding to its cell surface receptor, and is a potent inhibitor of IL-27 signaling, as shown by its ability to specifically block IL-27-mediated STAT activation, at low molar excess over IL-27. Also, we found that serum levels of sIL-27Rα were elevated in patients with Crohn's disease, a Th1-mediated disease. These findings suggest that sIL-27Rα may play important immunoregulatory functions under normal and pathological conditions.

Abstract
The prevalence of asthma and obesity is increasing worldwide, and obesity is a well-documented risk factor for asthma. The mechanisms underlying this association and parallel time trends remain largely unknown but genetic factors may be involved. Here, we report on a common ~0.45 Mb genomic inversion at 16p11.2 that can be accurately genotyped via SNP array data. We show that the inversion allele protects against the joint occurrence of asthma and obesity in five large independent studies (combined sample size of 317 cases and 543 controls drawn from a total of 5,809 samples; combined OR = 0.48, p = 5.5 × 10(-6)). Allele frequencies show remarkable worldwide population stratification, ranging from 10% in East Africa to 49% in Northern Europe, consistent with discordant and extreme genetic drifts or adaptive selections after human migration out of Africa. Inversion alleles strongly correlate with expression levels of neighboring genes, especially TUFM (p = 3.0 × 10(-40)) that encodes a mitochondrial protein regulator of energy balance and inhibitor of type 1 interferon, and other candidates for asthma (IL27) and obesity (APOB48R and SH2B1). Therefore, by affecting gene expression, the ~0.45 Mb 16p11.2 inversion provides a genetic basis for the joint susceptibility to asthma and obesity, with a population attributable risk of 39.7%. Differential mitochondrial function and basal energy balance of inversion alleles might also underlie the potential selection signature that led to their uneven distribution in world populations.

Abstract
This study investigated the association between IL-27 gene polymorphisms and susceptibility to epithelial ovarian cancer in a Chinese population and discusses the risk factors associated with survival time. We collected data on 229 patients diagnosed with epithelial ovarian cancer, from 15 to 77 years of age with a long clinical follow-up period. Polymerase chain reaction-restriction fragment length polymorphism was performed to determine the genotype of IL-27 gene polymorphisms. Ovarian cancer-specific survival (OCSS) according to genotype of IL-27 gene polymorphisms was explored by Kaplan-Meier analysis and Cox proportional hazards modeling. Significant differences for genotype frequencies of both SNP sites were found between cases and controls. Both allele G frequencies were significantly greater among the cases (rs153109: 0.404 vs. 0.303, P = 0.001, odds ratio [OR] = 1.333, 95% confidence interval [CI] = 1.133-1.567; rs17855750: 0.146 vs. 0.083, P = 0.001, OR = 1.766, 95% CI = 1.258-2.481). Haplotype analysis showed haplotypes AG, GT and GG were associated with increased ovarian cancer susceptibility while AT was a protective haplotype. Advanced FIGO stage (stages III + IV) and non-optimal cytoreductive surgery (residual tumor ≥1 cm) were poor prognostic factors in the univariate analysis (P = 0.003, P = 0.049). However, FIGO stage was found to be the only independent significant prognostic factor by Cox proportional hazards analysis (P = 0.042). IL-27p28 mRNA expression was significantly decreased in ovarian cancer patients (P < 0.0001), while no significant relationship was found between IL-27p28 mRNA expression and polymorphism of rs153109 and rs17855750 (P = 0.193 and P = 0.146, respectively). Our study suggests that IL-27 gene polymorphisms may be involved in the susceptibility to epithelial ovarian cancer, but not in survival in a clinic-based Chinese population. Haplotype analysis of these two SNPs seems to be an important mark to predict the disease susceptibility. Advanced FIGO stage, as the only significant, independent risk factor, predicts poor clinical outcomes for patients diagnosed with epithelial ovarian cancer. The decreased expression of IL-27p28 mRNA in ovarian cancer might indicate the antitumor activities of this novel cytokine.

Abstract
The aim of the present study was to investigate the association of single nucleotide polymorphisms (SNP) of the interleukin-27 (IL-27) genes with the risk for immune thrombocytopenia (ITP). In this case-control study, the genotyping of IL-27 rs153109 polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). In ITP patients, the frequencies of GG, GA and AA genotypes, and G and A alleles were 9.7%, 58.5%, 31.8%, 38.9% and 61.1%, respectively. There was no significant difference in genotype and alleles distribution between the ITP patient and the healthy controls (p = 0.68 and 0.80, respectively). Similar results were found between the two groups when stratified by the age and disease course including non-chronic adult, chronic adult, non-chronic childhood, and chronic childhood. In conclusion, the IL-27 polymorphism may not be involved in susceptibility to ITP in a Chinese population.

Abstract
A growing body of evidence suggests an essential role of the heterodimeric cytokine, IL-27, for regulating immunity. IL-27 is composed of two subunits (p28 and EBI3) and is classified as a member of the IL-12 family of cytokines. APCs have been recognized as a major cellular source of IL-27 following activation with microbial products or IFNs (types I and II). In this review, we describe the current knowledge of the implications of IL-27 during the pathogenesis of infectious and autoimmune diseases. Experimental studies have used genetically targeted IL-27RA-/- mice, EBI3-/- mice, and p28-/- mice or involved study designs with administration of bioengineered IL-27/IL-27RA homologs. Whereas many reports have described that IL-27 suppresses inflammation, we also review the current literature, suggesting promotion of inflammation by IL-27 in some settings. Recent advances have also been made in understanding the cross-talk of cleavage products of the complement system with IL-27-mediated immune responses. Additional data on IL-27 have been obtained recently by observational studies in human patients with acute and chronic inflammatory diseases. Collectively, the findings from the past decade identify IL-27 as a critical immunoregulatory cytokine, especially for T cells, whereas some controversy is fueled by results challenging the view of IL-27 as a classical silencer of inflammation.

Abstract
Severe asthma is thought to be a heterogeneous disease with different phenotypes predicated primarily on the nature of the inflammatory cell infiltrate and response to corticosteroid therapy. This group of patients often has refractory disease with an associated increase in morbidity and mortality, and there remains a need for better therapies for severe asthmatics. Inflammatory changes in asthma are driven by immune mechanisms, within which interleukins play an integral role. Interleukins are cell-signaling cytokines that are produced by a variety of cells, predominantly T cells. Knowledge about their actions has improved the understanding of the pathogenesis of asthma and provided potential targets for novel therapies. To date, this has not translated into clinical use. However, there are ongoing clinical trials that use monoclonal antibodies for various interleukins, some of which have shown to be promising in Phase II studies.

Abstract
BACKGROUND AND OBJECTIVE Hepatocellular carcinoma (HCC) is multifactorial, and the genetic background may be a crucial etiologic factor. Interleukin-27 (IL-27) is a novel IL-12 family member which plays an important role in antitumor immunity. Mutations in the IL27 gene may lead to altered cytokine production and/or activity and thus modulate individual's susceptibility to HCC. In this study, we investigated the association between IL27 gene polymorphisms and HBV-related diseases risk in a Chinese population. METHODS Studied subjects were divided into four groups: 112 patients with chronic hepatitis B (CHB), 65 patients with hepatitis B virus (HBV)-related liver cirrhosis (LC), 107 patients with HBV-related HCC, and 105 healthy controls. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) strategy and polymerase chain reaction-sequence specific primer (PCR-SSP) strategy were used to detect IL27 gene -964A/G and 2905T/G polymorphisms, respectively. DNA sequencing was used to validate genotype results. RESULTS There were no significant differences in the genotype and allele frequencies of IL27 gene polymorphisms between the groups of patients and healthy controls. Furthermore, no association was found between the distributions of the haplotypes and HCC risk. CONCLUSION These findings indicate that the genetic variants in IL27 gene may not contribute to HCC development. Further studies with large sample size should be conducted to validate this association.

Abstract
It has been more than 15 years since the identification of individual interleukin-27 (IL-27) and IL-27 receptor components. The last decade has seen the description of the signaling pathways engaged by IL-27, and an appreciation has emerged that this cytokine can modulate the intensity and duration of many classes of T cell responses. Here we provide an overview of the immunobiology of IL-27 and review advances in understanding the functions of individual IL-27 and IL-27 receptor subunits and the role of IL-27 in dictating the balance between protective and pathological immunity. Additionally, this cytokine has been proposed as a therapy to modify inflammatory conditions or to promote antitumor responses, and situations where experimental and clinical data sets implicate IL-27 in the outcome of disease are highlighted.

Abstract
BACKGROUND Recently, a new subpopulation of T cells, the Th17 subset, has been implicated in autoimmune diseases. Its development is influenced by IL-27, expressed in macrophages or dendritic cells. IL-27 blockage delays the onset of diabetes in non obese diabetes mouse, but its role in type 1 diabetes (T1D) in human has not been reported yet. The aim of this study was identify variants in the entire coding regions of IL-27 gene, including the 5' proximal region, and their possible association with the disease. METHODS Those regions were amplified by polymerase chain reaction followed by automatic sequencing and restriction fragments length polymorphisms. The cohort involved 614 individuals - 318 patients with T1D (19.6 ± 11.2 y, 129M/189F) and 296 healthy control subjects (30.3 ± 13.2 y, 131M/165F). RESULTS We identified eight allelic variants in the 5' proximal and coding regions of IL-27 gene, including two new variants: the c.-324 C>T in the 5' proximal region and the c.521 G>C in exon 5. None of these variants compromised transcription factor binding sites or the protein structure. The frequency of the alleles and genotypes of IL-27 variants did not differ between T1D patients and controls. There was no association between IL27 variants with gender, ethnicity, age at diagnosis of diabetes or presence of pancreatic and extrapancreatic autoantibodies. CONCLUSION Our findings suggest that allelic variants in IL27 are not associated with susceptibility to T1D in a Brazilian population.
