Abstract
Background IL-19 and IL-24 induce proinflammatory cytokine production through the Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway. The primary objective of this study was to investigate any changes in IL-19 and IL-24 expression between inflammatory bowel disease (IBD) patients and healthy controls, as well as before and after the initiation of biologics. The secondary objective was to investigate any relation between their expression and disease phenotype and activity. Methods IL-19 and IL-24 expression was measured in intestinal tissue samples from 121 patients with moderate to severe IBD versus healthy controls using immunohistochemistry. Their expression was then measured 12 months after treatment on the patient group treated with biologics. The disease activity was measured before and after treatment using the Harvey Bradshaw Index (HBI) for Crohn's disease (CD) patients and the Mayo Score (MS) for ulcerative colitis (UC) patients. Data were analyzed using SPSS (IBM Inc., Armonk, New York). Results IL-19 expression was raised in the IBD group versus healthy controls. In the CD group, the IL-19 expression was related with the disease activity score post-biologic treatment. IL-24 was also highly expressed in patients with active UC and CD and was increased post-treatment. Its expression in UC was statistically related with the MS. Conclusions IL-24 and IL-19 are key factors in IBD-related intestinal inflammation and this is one of the few human studies to suggest that. An immunosuppressive role of IL-24 was demonstrated in the UC group. A future use as biomarkers of disease activity and response to treatment might be feasible.

Abstract
Interleukins are potential therapeutic targets that can alter the prognosis and progression of inflammatory bowel disease (IBD). The roles of IL-6, IL-10, IL-17, and IL-23 have been extensively studied, setting the stage for the development of novel treatments for patients with IBD. Other cytokines have been less extensively studied. Members of the IL-20 family, mainly IL-19 and IL-24, are involved in the pathogenesis of IBD, but their exact role remains unclear. Similarly, IL-33, a newly identified cytokine, has been shown to control the Th1 effector response and the action of colonic Tregs in animal models of colitis and patients with IBD. IL-21 is involved in the Th1, Th2, and Th17 responses. Data support a promising future use of these interleukins as biomarkers of severe diseases and as potential therapeutic targets for novel monoclonal antibodies. This review aims to summarize the existing studies involving animal models of colitis and patients with IBD to clarify their role in the intestinal mucosa.

Abstract
The imbalance of mucosal immunity in the lower gastrointestinal tract can lead to chronic inflammatory bowel diseases (IBDs), including Crohn's disease and ulcerative colitis. IBD is a chronic inflammatory disorder that causes small and/or large intestines ulceration. According to previous studies, recombinant interleukin (IL)-10 protein and genetically modified bacteria secreting IL-10 ameliorate dextran sulfate sodium (DSS)-induced colitis in mice. IL-19 is a transcriptional activator of IL-10 and can alter the balance of T helper 1 (Th)1/Th2 cells in favor of Th2. In this study, we aimed to investigate whether the expression of the murine IL-19 gene carried by Salmonella choleraesuis (S. choleraesuis) could ameliorate murine IBD. Our results showed that the attenuated S. choleraesuis could carry and express the IL-19 gene-containing plasmid for IBD gene therapy by reducing the mortality and clinical signs in DSS-induced acute colitis mice as compared to the untreated ones. We also found that IL-10 expression was induced in IL-19-treated colitis mice and prevented inflammatory infiltrates and proinflammatory cytokine expression in these mice. We suggest that S. choleraesuis encoding IL-19 provides a new strategy for treating IBD in the future.

Abstract
Background: Colorectal cancer (CRC) is a major public health problem worldwide and in Tunisia. It ranks among the main cancers in terms of incidence and cancer-related cause of death. Its pathogenesis is currently considered to be multifactorial involving genetic and environmental factors. Recent studies have suggested that the gene encoding the β1 subunit of the IL-12 receptor, an important pro-inflammatory cytokine of the anti-tumor response, could be involved in the susceptibility to inherited CRC. Hence, it would be interesting to study the role of single nucleotide polymorphisms (SNPs) within the IL-12RB1 gene (rs401502 and rs11575934) in CRC susceptibility. Aim: Our purpose was to assess whether genetic variants IL-12RB1 +1196G/C (rs401502) and IL-12RB1 +705A/G (rs11575934) within the IL-12RB1 gene are associated with the sporadic CRC risk. Methods: A total of 110 Tunisian patients with sporadic CRC and 141 healthy control subjects were included in this study. Genotyping was performed by high-resolution melting (HRM) analysis. All results were confirmed by direct DNA sequencing or PCR-RFLP methods. Later, the allele frequencies and genotype distribution were established and compared between the control group and CRC patients. Results: The obtained results showed that the two target SNPs were in Hardy–Weinberg equilibrium (HWE) in both patients and controls. Minor allele frequencies of rs401502 SNP were 16.4% in CRC cases and 23.8% in controls. Mutant allele of rs11575934 SNP was present with 21.4% in CRC patients and 29.8% in control group. An association study showed a significant association of two target polymorphisms with CRC, according to the dominant genetic model with OR = 0.577, 95% CI = [0.343 to 0.972], p = 0.038 and OR = 0.547, 95% CI = [0.328 to 0.911], p = 0.02, respectively. Conclusion: In this study, we found, for the first time, a potential protective effect of two SNPs in the IL-12RB1 gene, namely rs401502 and rs11575934, in sporadic colorectal cancer in Tunisians.

Abstract
Numerous cytokines are involved in acne vulgaris pathogenesis, though few studies correlate interleukin IL-19 to acne vulgaris. So this study aimed to assess the IL-19 (rs 2243191) gene polymorphism and its serum level in acne vulgaris. This case-control study involved 90 acne vulgaris cases and 90 age- and sex-matched controls. Acne severity was assessed according to Global Acne Grading System (GAGS), and serum IL-19 was assessed by ELISA and IL-19 (rs 2243191) gene polymorphism was assessed by real time PCR. This study showed that acne cases had significantly higher IL-19 levels than controls. Also, its level was significantly higher in severe cases than moderate and mild cases. Regarding IL-19 gene polymorphism (rs 2243191), TT and CT genotypes were significantly higher in patients than in controls. The incidence of minor allele T was greater in patients than in controls. There were significant differences between IL-19 genotypes and disease severity. Serum IL-19 was significantly higher in genotypes TT and CT acne cases than in those with genotype CC. We concluded that TT genotype of IL-19 might be a hereditary risk factor for acne vulgaris development. It is associated with a high IL-19 serum level, which could be a marker of acne severity. . .

Abstract
Objective Abnormal B cell lymphoma-2 (Bcl-2) and interleukin-19 (IL-19) expression is
closely related to systemic lupus erythematosus (SLE) pathogenesis. We aimed
to determine whether BCL2 polymorphisms and a single
nucleotide polymorphism (SNP) of IL19 are significantly
associated with SLE susceptibility and if this is affected by synergism
between IL19 and BCL2 genotypes. Methods This observational cohort study randomly enrolled 150 patients with SLE and
150 healthy controls. Major BCL2 and IL19
allele and genotype distributions were examined in the two groups. The
IL19 SNP rs2243188 was determined using the TaqMan-MGB
probe method. The synergistic effect between BCL2 and
IL19 and clinical symptoms of SLE was also
analyzed. Results The distribution of major BCL2 genotypes and common
BCL2 alleles, especially for genotypes 191, 193, and
197, differed significantly between patients and controls. A significant
difference in the dominant genetic model was also observed between groups,
but not in the recessive model. The risk of disease in individuals who
carried both 195-bp BCL2 and 138-bp IL19
susceptibility alleles was higher than in those carrying either allele
alone. Conclusions This preliminary study suggested that BCL2 polymorphisms and
the IL19 SNP rs2243188 are closely related to the
pathogenesis of SLE.

Abstract
The cytokine interleukin-19 (IL-19) is a member of the IL-10 family that includes IL-20,
IL-22, IL-24, and IL-26. Previous studies indicated that IL-19 is produced by
keratinocytes, epithelial cells, macrophages, and B-cells. Especially, the number of
IL-4-producing T cells increased, whereas the number of IFN-γ-producing T cells decreased
when naive T cells from healthy people were cultured in the presence of IL-19. There is an
increasing body of data demonstrating that IL-19 is associated with the development of
type 1 helper T cell-responses, although IL-19 was originally associated with the
development of type 2 helper T cell-responses. In this review, we will attempt to discuss
current knowledge about the role of IL-19 on several T cell response-mediated inflammatory
diseases including inflammatory bowel disease and hypersensitivity.

Abstract
This review describes the IL-20 family of cytokines in rheumatoid arthritis (RA) and spondyloartrhitits (SpA) including psoriatic arthritis. The IL-20 receptor (R) cytokines IL-19, IL-20, and IL-24 are produced in both the peripheral blood and the synovial joint and are induced by Toll-like receptor ligands and autoantibody-associated immune complexes in monocytes. IL-19 seems to have anti-inflammatory functions in arthritis. In contrast, IL-20 and IL-24 increase the production of proinflammatory molecules such as monocyte chemoattractant protein 1 and are associated with bone degradation and radiographic progression. IL-22 is also associated with progression of bone erosions. This suggests that the IL-22RA1 subunit shared by IL-20, IL-22, and IL-24 is important for bone homeostasis. In line with this, the IL-22RA1 has been found on preosteoclasts in early RA. IL-26 is produced in high amounts by myofibroblasts and IL-26 stimulation of monocytes is an important inducer of Th17 cells in RA. This indicates a role for IL-26 as an important factor in the interactions between resident synovial cells and infiltrating leukocytes. Clinical trials that investigate inhibitors of IL-20 (fletikumab) and IL-22 (fezakinumab) in psoriasis and RA have been terminated. Instead, it seems that the strategy for modulating the IL-20 cytokine family should take the overlap in cellular sources and effector mechanisms into account. The redundancy encourages inhibition of more than one cytokine or one of the shared receptors. All IL-20 family members utilize the Janus kinase signaling pathway and are therefore potentially inhibited by drugs targeting these enzymes. Effects and adverse effects in ongoing clinical trials with inhibitors of IL-22 and the IL-22RA1 subunit and recombinant IL-22 fusion proteins will possibly provide important information about the IL-20 subfamily of cytokines in the future.

Abstract
Autoimmune/inflammatory intestinal diseases, such as Crohn’s disease and ulcerative colitis, infectious gastrointestinal diseases, and gastrointestinal cancers, such as colorectal cancer, are worldwide a significant health problem. Intercellular communication and direct contact with the environment as the microbiota colonizes the gastrointestinal surface facilitates these diseases. Cytokines mediate the intercellular communication to maintain the equilibrium between host and environment and to regulate immune responses. One cytokine family that exchange information between immune cells and epithelial cells is the IL-20 cytokine family which includes the cytokines IL-19, IL-20, IL-22, IL-24, and IL-26. These cytokines share common receptor subunits and signaling pathways. IL-22 is the most intensively studied cytokine within this family in contexts of gastrointestinal disease, but the importance of other family members is more and more appreciated. In this review, the potential function of IL-20 cytokines concerning gastrointestinal conditions is discussed.

Abstract
BACKGROUND The IL10 family of genes includes crucial immune regulators. We tested the hypothesis that single nucleotide polymorphisms (SNPs) in IL10, IL19, IL20, and IL24 of the IL10 family gene cluster alter the clinical outcome of septic shock. METHODS Patients with septic shock (n = 1,193) were genotyped for 13 tag SNPs of IL10, IL19, IL20, and IL24. IL20 gene expression was measured in genotyped lymphoblastoid cells in vitro. Cardiac surgical ICU patients (n = 981) were genotyped for IL20 rs2981573 A/G. The primary outcome variable was 28-day mortality. RESULTS Patients with the G allele of IL20 rs2981573 had a significantly increased hazard of death over the 28-day period compared to patients with the A allele in the septic shock cohort (adjusted hazard ratio 1.27; 95% confidence interval 1.10-1.47; p = 8.0 × 10-4). Patients with the GG genotype had more organ dysfunction (p < 0.05). The GG genotype was associated with increased IL20 gene expression in stimulated lymphoblastoid cells in vitro (p < 0.05). The cardiac surgical ICU patients with the GG genotype had an increased length of ICU stay (p = 0.032). CONCLUSIONS The GG genotype of IL20 rs2981573 SNP was associated with increased IL20 gene expression and increased adverse outcomes in patients with septic shock and following cardiac surgery.

Abstract
OBJECTIVE To study the association between the single nucleotide polymorphisms (SNP) of interleukin (IL)-19 and susceptibility to hepatitis B virus (HBV) infection in children. METHODS A case-control study was performed, and 136 children with positive HBsAg(case group) and 297 healthy children with negative HBsAg(control group) were enrolled. PCR and DNA sequencing were used for genotyping. RESULTS There were significant differences in the frequencies of genotypes of IL-19 rs1798 between the case and control groups. The case group also had a significantly higher proportion of children with CG genotype than the control group (p<0.05). There were significant differences in the frequencies of genotypes and alleles of IL-19 rs2243191 between the HBV infection and non-infection groups among children who born to HBV-positive mothers. The infection group had significantly higher proportions of children with TC and CC genotypes and C allele than the non-infection group (p<0.05). CONCLUSIONS The SNP of IL-19 rs1798 may be associated with susceptibility to hepatitis B in children, and the SNP of IL-19 rs2243191 may be associated with susceptibility to breakthrough HBV infection in children at a high risk of HBV infection.

Abstract
OBJECTIVE To evaluate the clinical value of a new type of fluorescence lateral flow immunoassay in rapid detection of influenza A virus. METHODS A total of 378 samples of nasopharyngeal secretions were collected from 378 children with influenza-like symptoms to detect the influenza A virus by fluorescence lateral flow immunoassay, colloidal gold immunoassay, and RT-PCR between July 2015 and August 2015. RESULTS Of the 378 samples, 81 (21.4%) were positive for influenza A virus by RT-PCR. Compared with RT-PCR, the sensitivities of fluorescence lateral flow immunoassay and colloidal gold immunoassay were 90.1% (73/81) and 75.3% (61/81), respectively, and the specificities were 99.3% (295/297) and 98.3% (292/297), respectively. The average threshold cycle (Ct) value for the positive samples detected by the fluorescence lateral flow immunoassay (30.6) was higher than that for the positive samples detected by the colloidal gold immunoassay (28.7). CONCLUSIONS Compared with colloidal gold immunoassay, fluorescence lateral flow immunoassay has higher sensitivity, specificity, and concordance rate with RT-PCR, suggesting that it can be used for early screening and diagnosis of influenza A.

Abstract
BACKGROUND Ulcerative colitis (UC) is a multifactorial and polygenic disease. Interleukin-22 (IL-22) is an immunomodulatory cytokine that belongs to the IL-10 family. Currently, some IL-22 polymorphisms have been associated with inflammatory processes such as rheumatoid arthritis and psoriasis vulgaris, but there are no studies on UC. AIM The aim of this work was to study the frequency of polymorphisms of IL-22 in Mexican patients with UC. METHODS We studied a total of 199 Mexican patients with confirmed UC and 697 healthy controls. All individuals were born in Mexico, at least three family generations earlier. A blood sample was obtained from the UC patients and healthy controls in order to perform DNA extraction and then to determine the frequency of IL-22 polymorphisms (rs2227485, rs2272478, rs2227491). RESULTS No statistical significance was found in the gene and genotype frequencies of three SNPs of IL-22 (rs2227485, rs2272478, rs2227491) between the UC patients and healthy controls. No association was found between those IL-22 SNPs and clinical features of UC. CONCLUSIONS There was no association between IL-22 SNPs (rs2227485, rs2272478, rs2227491) and the development of UC in a Mexican population.

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
STAT3 regulates the expansion of myeloid-derived suppressor cells (MDSCs) during
inflammation, infection and cancer. Hyperactivation of STAT3 in
gp130757F/F mice is associated with protection from experimental
colitis. This study determined mechanisms for this protection and compared this to
mice with myeloid-specific STAT3-deficiency (LysMcre/STAT3flox;
gp130757F/F LysMcre/STAT3flox). Acute and chronic
colitis was induced and colons were removed for histological, mRNA and protein
analysis. Cell populations from spleen, mesenteric lymph node and colon were
analyzed for different myeloid cell populations using flow cytometry. Functions of
MDSCs and LPS-stimulated peritoneal macrophages were further characterized by in
vitro and in vivo assays. Here we show that the resistance to
experimental colitis in gp130757F/F mice is via myeloid-cell specific
STAT3 activation, MDSC expansion and increased production of suppressive and
protective cytokines.

Abstract
Genetic factors play a significant role in determining inflammatory bowel disease (IBD) susceptibility. Epidemiologic data support genetic contribution to the pathogenesis of IBD, which include familial aggregation, twin studies, and racial and ethnic differences in disease prevalence. Recently, several new genes have been identified to be involved in the genetic susceptibility to IBD. The characterization of novel genes potentially will lead to the identification of therapeutic agents and clinical assessment of phenotype and prognosis in patients with IBD. The development of genetic markers associated with clinical outcomes in patients with IBD will be very important in the future. The progress of molecular biology tools (microarrays, proteomics, and epigenetics) have progressed the field of the genetic markers discovery. The advances in bioinformatics coupled with cross-disciplinary collaborations have greatly enhanced our ability to retrieve, characterize, and analyze large amounts of data generated by the technological advances. The techniques available for markers development are genomics (single nucleotide polymorphism genotyping, pharmacogenetics, and gene expression analyses) and proteomics. This could be a potential great benefit in predicting the course of disease in individual patients and in guiding appropriate medical therapy.

Abstract
Inflammatory bowel diseases (IBD) include ulcerative colitis and Crohn's disease. The immune response in ulcerative colitis is different from the Crohn's disease. Accumulating evidence suggests that IBD results from an inappropriate inflammatory response to intestinal microbes in a genetically susceptible host. Several immunoregulatory abnormalities have been reported in patients with IBD, including the ratio of proinflammatory (tumor necrosis factor alpha, IL-6, IL-1-β) to immunoregulatory cytokines (IL-10, TGF-β, IL-35) and selective activation of T-helper (Th) lymphocyte subsets (Th1, Th2, Th9, Th17, and regulatory T cells). The purpose of this review is to show the immunoregulatory pathways (regulatory cells and cytokines) involved in IBD published in recent years.

Abstract
Spondyloarthritis (SpA) is a group of immune mediated inflammatory diseases affecting joints, gut, skin and entheses. The inflammatory process involves activation of Toll-like receptor (TLR)-2 and TLR-4 and production of cytokines and chemokines such as monocyte chemoattractant protein 1 (CCL2/MCP-1). This proinflammatory chemokine recruits monocytes to sites of inflammation and is central in the development of several immune-mediated inflammatory diseases. Interleukin (IL)-19 is a member of the IL-10 family of cytokines. IL-19-deficient mice are more susceptible to innate-mediated colitis and develop more severe inflammation in response to injury. In this work, we studied inducers of IL-19 production and effect of IL-19 on the production of CCL2/MCP-1 and proinflammatory cytokines in peripheral blood mononuclear cells (PBMCs) from healthy controls (HCs) and in PBMCs and synovial fluid mononuclear cells (SFMCs) from SpA patients. Further, we measured IL-19 in plasma from HCs and in plasma and synovial fluid from SpA patients. Constitutive IL-19 expression was present in both PBMCs and SFMCs and the secretion of IL-19 was increased by TLR-2 and TLR-4 ligands. Neutralizing IL-19 in HC PBMCs and SpA SFMCs resulted in increased production of CCL-2/MCP-1. IL-19 concentrations were decreased in synovial fluid compared with plasma and associated inversely with disease activity in SpA. SpA SFMCs produced less IL-19 in response to LPS compared with HC PBMCs. These findings indicate that IL-19 production is diminished in SpA. Taken together, impaired IL-19 control of the innate immune system might be involved in the pathogenesis of SpA.

Abstract
Importance of chronic fibroproliferative diseases (FDs) including pulmonary fibrosis, chronic kidney diseases, inflammatory bowel disease, and cardiovascular or liver fibrosis is rapidly increasing and they have become a major public health problem. According to some estimates about 45% of all deaths are attributed to FDs in the developed world. Independently of their etiology the common hallmark of FDs is chronic inflammation. Infiltrating immune cells, endothelial, epithelial, and other resident cells of the injured organ release an orchestra of inflammatory mediators, which stimulate the proliferation and excessive extracellular matrix (ECM) production of myofibroblasts, the effector cells of organ fibrosis. Abnormal amount of ECM disturbs the original organ architecture leading to the decline of function. Although our knowledge is rapidly expanding, we still have neither a diagnostic tool to detect nor a drug to specifically target fibrosis. Therefore, there is an urgent need for the more comprehensive understanding of the pathomechanism of fibrosis and development of novel diagnostic and therapeutic strategies. In the present review we provide an overview of the common key mediators of organ fibrosis highlighting the role of interleukin-10 (IL-10) cytokine family members (IL-10, IL-19, IL-20, IL-22, IL-24, and IL-26), which recently came into focus as tissue remodeling-related inflammatory cytokines.

Immunogenetic influences on acquisition of HIV-1 infection: consensus findings from two African cohorts point to an enhancer element in IL19 (1q32.2). Genes Immun 2015; 16:213-20.

Abstract
Numerous reports have suggested that immunogenetic factors may influence HIV-1 acquisition, yet replicated findings that translate between study cohorts remain elusive. Our work aimed to test several hypotheses about genetic variants within the IL10-IL24 gene cluster that encodes interleukin (IL)-10, IL-19, IL-20, and IL-24. In aggregated data from 515 Rwandans and 762 Zambians with up to 12 years of follow-up, 190 single nucleotide polymorphisms (SNPs) passed quality control procedures. When HIV-1-exposed seronegative subjects (n = 486) were compared with newly seroconverted individuals (n = 313) and seroprevalent subjects (n = 478) who were already infected at enrollment, rs12407485 (G>A) in IL19 showed a robust association signal in adjusted logistic regression models (odds ratio = 0.64, P = 1.7 × 10−4, and q = 0.033). Sensitivity analyses demonstrated that (i) results from both cohorts and subgroups within each cohort were highly consistent; (ii) verification of HIV-1 infection status after enrollment was critical; and (iii) supporting evidence was readily obtained from Cox proportional hazards models. Data from public databases indicate that rs12407485 is part of an enhancer element for three transcription factors. Overall, these findings suggest that molecular features at the IL19 locus may modestly alter the establishment of HIV-1 infection.

Abstract
BACKGROUND Interleukin-22 (IL-22) is a member of the IL-10 family of anti-inflammatory cytokines that mediates epithelial immunity. IL-22 expression was found to be increased in patients with ulcerative colitis (UC). Whether genetic polymorphisms of IL-22 also influence UC risk is still unknown. The purpose of this study was to investigate the association between the IL-22 gene polymorphisms (-429 C/T, +1046 T/A and +1995 A/C) and the risk of UC in Chinese Han patients. METHODS This hospital-based case-control study comprised 180 patients with UC and 180 age- and gender-matched controls. Genotypes of 3 common polymorphisms of the IL-22 gene were determined by fluorogenic 5' exonuclease assays (TaqMan). RESULTS Patients with UC had a significantly higher frequency of IL-22 -429 TT genotype [odds ratio (OR) =2.43, 95% confidence interval (CI) =1.35, 4.37; P=0.003] and -429 T allele (OR =1.54, 95% CI=1.14, 2.07; P=0.004) than controls. The findings are still emphatic by the Bonferroni correction. The IL-22+1046 T/A and IL-22+1995 A/C gene polymorphisms were not associated with a risk of UC. When stratifying by clinical type, location and disease severity of UC, no significant differences were found in any groups. CONCLUSION This is the first study to provide evidence for an association of IL-22 -429 C/T gene polymorphisms with UC risk. Additional well-designed large studies were required for the validation of our results.

Abstract
Psoriasis is a common chronic inflammatory disease with characteristic skin alterations and functions as a model of immune-mediated disorders. Cytokines have a key role in psoriasis pathogenesis. Here, we demonstrated that out of 30 individually quantified cytokines, IL-19 showed the strongest differential expression between psoriatic lesions and healthy skin. Cutaneous IL-19 overproduction was reflected by elevated IL-19 blood levels that correlated with psoriasis severity. Accordingly, anti-psoriatic therapies substantially reduced both cutaneous and systemic IL-19 levels. IL-19 production was induced in keratinocytes by IL-17A and was further amplified by tumor necrosis factor-α and IL-22. Among skin cells, keratinocytes were found to be important targets of IL-19. IL-19 alone, however, regulated only a few keratinocyte functions. While increasing the production of S100A7/8/9 and, to a moderate extent, also IL-1β, IL-20, chemokine C-X-C motif ligand 8, and matrix metalloproteinase 1, IL-19 had no clear influence on the differentiation, proliferation, or migration of these cells. Importantly, IL-19 amplified many IL-17A effects on keratinocytes, including the induction of β-defensins, IL-19, IL-23p19, and T helper type 17-cell- and neutrophil-attracting chemokines. In summary, IL-19 as a component of the IL-23/IL-17 axis strengthens the IL-17A action and might be a biomarker for the activity of this axis in chronic inflammatory disorders.

Abstract
Interleukin 15 (IL-15) is a Th1-related cytokine that triggers inflammatory cell recruitment with implications for pathogenesis in ulcerative colitis. The IL-15 gene is located within a 35 kb region of the q28-31 locus of chromosome 4. In the present work, the role of IL-15 gene polymorphisms as susceptibility markers for UC was evaluated. Seven polymorphisms of IL-15 (rs3806798, rs10833, rs4956403, rs2254514, rs2857261, rs10519613, and rs1057972) were genotyped by 5' exonuclease TaqMan genotyping assays in a group of 199 Mexican patients with UC and 698 Mexican Mestizo healthy unrelated individuals. UC patients and healthy controls showed similar distribution of the rs3806798, rs10833, rs4956403, rs2857261, rs10519613, and rs1057972 polymorphisms. The rs2254514 polymorphism was significantly associated with decreased risk of UC as compared to controls under both dominant and additive models (OR 0.62, Pdom = 0.014 and OR 0.65, Padd = 0.02). The rs2254514 CC genotype was associated with young age at diagnosis <40 years (P = 0.03; OR 3.67). Five polymorphisms (rs1051613, rs2254514, rs2857261, rs1057972, and rs10833) were in strong linkage disequilibrium and were included in six haplotypes: H1 (ACAAC), H2 (CCGTC), H3 (CTAAT), H4 (CCAAT), H5 (CTAAC), and H6 (CCAAC). UC patients showed an increased frequency of the H6 haplotype (P = 0.005; OR 3.2) and a decreased frequency of the H5 haplotype (P = 0.031; OR 0.40). These results suggest that the IL-15 rs2254514 polymorphism might have an important role in the development of UC in the Mexican population. We were able to distinguish one risk and one protective uncommon haplotype for the development of UC.

Abstract
Interleukin (IL)-20 belongs to the IL-10 family and is a potent immunomodulatory cytokine with implications for pathogenesis in the inflammatory bowel disease (IBD). The interleukin 20 gene is located within a 200kb region of q31-32 locus of chromosome 1. No previous studies have reported this novel association between ulcerative colitis (UC) and IL-20 polymorphisms. In the present work, we evaluated the role of IL-20 gene polymorphisms as susceptibility markers for UC. Three polymorphisms of IL-20 gene (rs2981573, rs2232360, rs1518108) were genotyped by 5' exonuclease TaqMan genotyping assays on an ABI Prism 7900 HT Fast Real-Time PCR system in a group of 198 Mexican Mestizo patients with UC and 698 ethnically matched healthy unrelated individuals with no family history of UC. We found significant decreased frequencies of two IL-20 genotypes: GG (rs2981573) [10.6% vs. 17.6%, p=0.017, OR=0.55, 95% CI: 0.33-0.93] and GG (rs2232360) [10.6% vs. 17.6%, p=0.017, OR=0.55, 95% CI: 0.33-0.93] in UC patients as compared to healthy controls. No significant differences of gene frequencies were found between UC patients and healthy controls in the rs1518108 polymorphism. In the subgroup analysis, no differences were found between the IL-20 genotypes and the clinical characteristics of UC. The results suggest that the GG genotypes of the IL-20 polymorphisms (rs2981573 and rs2232360) might have an important role in the development of UC in the Mexican population.

Abstract
Cytokines are indispensable signals of the mucosa-associated immune system for maintaining normal gut homeostasis. An imbalance of their profile in favour of inflammation initiation may lead to disease states, such as that is observed in inflammatory bowel diseases (IBD). Although Crohn's disease (CD) is often described as a prototype of T-helper 1-type diseases, and ulcerative colitis (UC) is traditionally viewed as a T-helper 2-mediated condition, the classic paradigm, which categorises cytokines into pro- and anti-inflammatory groups, has recently been changed. The inflammation regulatory pathways may not be mutually exclusive as individual cytokines can have diverse and even opposing functions in various clinical and immunological settings. None the less there are many common immunological responses in IBD that are mediated by cytokines. Although they regulate and influence the development, course and recurrence of the inflammatory process, the concrete pathogenic role of these small signaling molecules is sometimes not unambiguous in the subtypes of the disease. Our aim is to review the current information about pro- and anti-inflammatory effects of traditionally studied and recently discovered cytokines in the pathogenesis of UC and CD. The better understanding of their production and functional activity may lead to the development of new therapeutic modalities.

Abstract
UNLABELLED Vesicoureteral reflux (VUR) is a common childhood problem, causing renal wounds and escalating the risk of renal deficiency and hypertension. A vast literature exists suggesting that genetic variations play a significant role in the pathogenesis of VUR. The aim of the present study was to estimate whether genetic polymorphisms of IL-19 (GC rs2243158, AT rs2243158) and IL-20 (AG rs2981573, TG rs2981572) genes are involved in the development of VUR. MATERIALS AND METHODS The tetra amplification mutation refractory system-polymerase chain reaction (Tetra-ARMS PCR) was applied for analyzing four polymorphic sites of IL-19 (GC rs2243158, AT rs2243158) and IL-20 (AG rs2981573, TG rs2981572) genes in 110 healthy controls and 124 VUR children. RESULTS A significant association was found between the combined genotypes of IL19GC+CC and IL20TG+GG and increased risk of VUR (OR = 1.90, 95% CL, 1.06-3.41; OR=1.87, 95% CL, 1.06-3.29, respectively). The frequency of allele G in both sites of IL-20 (IL20AG rs2981573 and IL20TG, rs2981572) showed a statistically significant difference (p = 0.01) between cases and controls in comparison with the wild type. The combined haplotype analysis of IL-19 and IL-20 polymorphic sites revealed that HT2, HT3 and HT5 haplotypes marginally increased the risk of VUR, but not statistically significantly. Gene-gene interaction data of IL-19 (GC rs2243158, AT rs2243158) and IL-20 (AG rs2981573, TG rs2981572) in various genotype patterns highlighted the fact that most of the genotype combinations increased the risk of disease insignificantly. CONCLUSION This is the first evidence regarding IL-19 and IL-20 cytokine genes polymorphism and risk of VUR, suggesting the need for further study with large sample size and in different populations to confirm the presented data.
