Abstract
Alopecia areata is a type of non-scarring hair loss. The dysregulation of numerous systemic Th1 (IL-2, IFN-γ, TNF, IL-12, and IL-18), Th2 (IL-4, IL-5, IL-6, IL-9, IL-10, IL-13, IL-17E, IL-31 and IL-33) and Th17 (IL-17, IL-17F, IL-21, IL-22, IL-23 and TGF-β) cytokines was observed in patients with alopecia areata. Positive correlations between the severity of alopecia areata and an increased serum level of various cytokines including IL-2, TNF, IL-12, IL-17, and IL-17E were reported in the literature. An increased serum level of numerous cytokines, such as IL-2, IL-6, TNF, IL-12, IL-17E, and IL-22, was described as positively correlated with the duration of the disease. Moreover, it was shown that increased pre-treatment serum level of IL-12 was a positive, while increased serum levels of IL-4 and IL-13 were negative prognostic markers for the efficacy of diphenylcyclopropenone. In conclusion, alopecia areata is associated with the dysregulation of systemic Th1, Th2 and Th17 cytokines with their role in the pathogenesis, clinical manifestations and prognosis of the disease. Available data indicate the most significant role of serum IL-2, TNF, IL-12, IL-17, and IL-17E as markers of disease activity. The serum levels IL-4, IL-12 and IL-13 may be useful as potential predictors of diphenylcyclopropenone efficacy.

Abstract
Pathogenic New World orthohantaviruses cause hantavirus cardiopulmonary syndrome (HCPS), a severe immunopathogenic disease in humans manifested by pulmonary edema and respiratory distress, with case fatality rates approaching 40%. High levels of inflammatory mediators are present in the lungs and systemic circulation of HCPS patients. Previous studies have provided insights into the pathophysiology of HCPS. However, the longitudinal correlations of innate and adaptive immune responses and disease outcomes remain unresolved. This study analyzed serial immune responses in 13 HCPS cases due to Sin Nombre orthohantavirus (SNV), with 11 severe cases requiring extracorporeal membrane oxygenation (ECMO) treatment and two mild cases. We measured viral load, levels of various cytokines, urokinase plasminogen activator (uPA), and plasminogen activator inhibitor-1 (PAI-1). We found significantly elevated levels of proinflammatory cytokines and PAI-1 in five end-stage cases. There was no difference between the expression of active uPA in survivors' and decedents' cases. However, total uPA in decedents' cases was significantly higher compared to survivors'. In some end-stage cases, uPA was refractory to PAI-1 inhibition as measured by zymography, where uPA and PAI-1 were strongly correlated to lymphocyte counts and IFN-γ. We also found bacterial co-infection influencing the etiology and outcome of immune response in two cases. Unsupervised Principal Component Analysis and hierarchical cluster analyses resolved separate waves of correlated immune mediators expressed in one case patient due to a sequential co-infection of bacteria and SNV. Overall, a robust proinflammatory immune response, characterized by an imbalance in T helper 17 (Th17) and regulatory T-cells (Treg) subsets, was correlated with dysregulated inflammation and mortality. Our sample size is small; however, the core differences correlated to survivors and end-stage HCPS are instructive.

Abstract
Coxsackievirus A2 (CVA2) has emerged as an active pathogen that has been implicated in hand, foot, and mouth disease (HFMD) and herpangina outbreaks worldwide. It has been reported that severe cases with CVA2 infection develop into heart injury, which may be one of the causes of death. However, the mechanisms of CVA2-induced heart injury have not been well understood. In this study, we used a neonatal mouse model of CVA2 to investigate the possible mechanisms of heart injury. We detected CVA2 replication and apoptosis in heart tissues from infected mice. The activity of total aspartate transaminase (AST) and lactate dehydrogenase (LDH) was notably increased in heart tissues from infected mice. CVA2 infection also led to the disruption of cell-matrix interactions in heart tissues, including the increases of matrix metalloproteinase (MMP)3, MMP8, MMP9, connective tissue growth factor (CTGF) and tissue inhibitors of metalloproteinases (TIMP)4. Infiltrating leukocytes (CD45+ and CD11b+ cells) were observed in heart tissues of infected mice. Correspondingly, the expression levels of inflammatory cytokines in tissue lysates of hearts, including tumor necrosis factor alpha (TNF-α), interleukin-1beta (IL-1β), IL6 and monocyte chemoattractant protein-1 (MCP-1) were significantly elevated in CVA2 infected mice. Inflammatory signal pathways in heart tissues, including phosphatidylinositol 3-kinase (PI3K)-AKT, mitogen-activated protein kinases (MAPK) and nuclear factor kappa B (NF-κB), were also activated after infection. In summary, CVA2 infection leads to heart injury in a neonatal mouse model, which might be related to viral replication, increased expression levels of MMP-related enzymes and excessive inflammatory responses.

Abstract
Imbalance in the immune response is one of the main pathogenic mechanisms of diseases related with human immunodeficiency virus (HIV)/human gammaherpesvirus 8 (HHV-8) coinfection, such as Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), multicentric Castleman disease (MCD) and the Kaposi's sarcoma-associated herpesvirus inflammatory cytokine syndrome (KICS). However, significant changes in pro- and anti-inflammatory cytokine levels may be observed in HIV/HHV-8 individuals who are negative for KS, PEL, MCD, and/or KICS. In this study, serum levels of interleukin-2 (IL-2), IL-4, IL-6, IL-10, tumor nucrosis factor α (TNF-α) and interferon γ (IFN-γ) were assessed in 69 HIV and 48 HIV/HHV-8 individuals, all negatives for HHV-8-related diseases. The cytokines were measured by flow cytometry and analyzed by the Mann-Whitney test. The p < .05 and 95% confidence interval were considered in all analyzes. IL-4 (p = .0155), IL-6 (p = .0036), and IL-10 (p = .0036) levels were significantly higher in HIV/HHV-8 patients than in the HIV group. On the other hand, IL-2 (p = .2295), TNF-α (p = .1216) and IFN-γ (p = .1178) did not differ between the groups analyzed. To our knowledge, to date, this is the first report on significant differences in the levels of IL-4 and IL-6 in HIV versus HIV/HHV-8 individuals. Finally, these early findings are important as a prognostic tool and contribute to clarifying the HHV-8-host interaction.

Abstract
OBJECTIVE This study aims to determine expression profiles of relevant genes in the early stages of post-traumatic heterotopic ossification (HO) in a rat model of Achilles tenotomy. METHODS A total of 80 male Sprague-Dawley rats were randomly assigned to two groups: the HO group and the control group. Tenotomy was performed in the Achilles tendon of the rats in the HO group, and no intervention was conducted in the control group. On the 3rd, 5th, 8th, and 14th days after the operation, 8 rats were taken from each group at each time point, and the Achilles tendon and surrounding tissue specimens were collected. Gene expressions of TGF-β, BMP, GDF, IL, and MMP families as well as TNF-α, HIF-1α chordin, gremlin, noggin, and NODAL were analyzed by qRT-PCR. The relevant genes that were highly expressed at different time points were screened, and immunohistochemical staining was then used to verify their expression. At the 10th week, HO formation was explored by radiographic and histological examination in the remaining 8 rats of each group. RESULTS Both the radiographic and histological analyses indicated that all the rats developed HO in the HO group (100%), whereas no HO occurred in the control group. Surrounding tissues obtained from the HO group showed significantly higher gene expressions of TGF-β1, BMP-1, IL1β, HIF-1α, and MMP-2 but lower expressions of BMP-4, GDF-8, and TNF-α compared with the control group. In addition, immunohistochemical staining confirmed the higher protein expression levels of relevant genes in the HO group. CONCLUSION TGF-β1, BMP-1, IL-1β, HIF-1α, MMP-2, BMP4, GDF-8, and TNF-α may be associated with the formation of traumatic HO; and BMP4, GDF-8, and TNF-α may play a protective role in the early stage of HO. In this study, we investigated the expression levels of the related cytokines in the early stages of traumatic HO in the Achilles tendon tenotomy rat model to better understand the pathogenesis of HO.

Abstract
PURPOSE To determine the concentrations of vitreous proinflammatory cytokines and angiogenesis-related growth cytokines in highly myopic (HM) patients and controls. METHODS Vitreous humor (VH) was obtained from patients during vitrectomy for rhegmatogenous retinal detachment (RRD), myopic retinoschisis (MRS), idiopathic epiretinal membrane (ERM), or macular hole (MH). High myopia was defined as an axial length (AL) of ≥26.0 mm and a spherical equivalent refractive error more negative than -6.0 D. A multiplex fluorescent-bead-based immunoassay was employed to measure the levels of 29 designated cytokines. The results were compared across groups. RESULTS Seventy-eight VH samples were collected from 78 patients (36 HM versus 42 controls). Vascular endothelial growth factor (VEGF) was significantly higher in the VH samples from HM patients than in those from the controls. Five inflammation-related factors, interferon γ (IFN-γ), interleukin 6 (IL6), IFN-γ-induced protein 10 (IP-10), eotaxin, and macrophage inflammatory protein 1α (MIP-1α), were significantly higher in the HM group than in the control group. The vitreous concentrations of well-known angiogenic growth factors monocyte chemoattractant protein 1 (MCP1) and IL5 were significantly elevated in the VH samples from HM patients. CONCLUSIONS Proinflammatory cytokines and angiogenic growth factors were elevated in the VH of HM patients, suggesting that an elevated inflammatory status and higher levels of angiogenic factors are present in eyes with HM.

Abstract
Identification of a suitable nonhuman primate (NHP) model of COVID-19 remains challenging. Here, we characterized severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in three NHP species: Old World monkeys Macaca mulatta (M. mulatta) and Macaca fascicularis (M. fascicularis) and New World monkey Callithrix jacchus (C. jacchus). Infected M. mulatta and M. fascicularis showed abnormal chest radiographs, an increased body temperature and a decreased body weight. Viral genomes were detected in swab and blood samples from all animals. Viral load was detected in the pulmonary tissues of M. mulatta and M. fascicularis but not C. jacchus. Furthermore, among the three animal species, M. mulatta showed the strongest response to SARS-CoV-2, including increased inflammatory cytokine expression and pathological changes in the pulmonary tissues. Collectively, these data revealed the different susceptibilities of Old World and New World monkeys to SARS-CoV-2 and identified M. mulatta as the most suitable for modeling COVID-19.

Abstract
Among hematologic malignancies, the classic Philadelphia-negative chronic myeloproliferative neoplasms (MPNs) are considered a model of inflammation-related cancer development. In this context, the use of immune-modulating agents has recently expanded the MPN therapeutic scenario. Cytokines are key mediators of an auto-amplifying, detrimental cross-talk between the MPN clone and the tumor microenvironment represented by immune, stromal, and endothelial cells. This review focuses on recent advances in cytokine-profiling of MPN patients, analyzing different expression patterns among the three main Philadelphia-negative (Ph-negative) MPNs, as well as correlations with disease molecular profile, phenotype, progression, and outcome. The role of the megakaryocytic clone as the main source of cytokines, particularly in myelofibrosis, is also reviewed. Finally, we report emerging intriguing evidence on the contribution of host genetic variants to the chronic pro-inflammatory state that typifies MPNs.

Abstract
Our purpose was to evaluate the concentrations of vitreous cytokines in patients with rhegmatogenous retinal detachment (RRD). We hypothesized that patients with macula on RRD have lower levels of cytokines compared to patients with macula off RRD and proliferative vitreoretinopathy (PVR). Vitreous fluids were collected during 23G pars plana vitrectomy from 58 eyes of 58 patients. Indication for vitrectomy included macula off and macula on RRD, PVR, and idiopathic epiretinal membrane (ERM). A multiplex chemiluminescent immunoassay was performed to measure the concentrations of 48 cytokines, chemokines, and growth factors. Levels of HGF, IL-6, IL-8, IL-16, IFN-gamma, MCP-1, and MIF were significantly higher in all groups of retinal detachment compared to ERM. Levels of CTACK, eotaxin, G-CSF, IP-10, MIG, SCF, SCGF-beta, SDF-1alpha were significantly higher in PVR compared to macula on RRD and ERM. Levels of IL-1ra, IL-5, IL-9, M-CSF, MIP-1alpha, and TRIAL were significantly higher in PVR compared to macula on RRD. Our results indicate that the position of macula lutea and the presence of PVR significantly influence vitreous cytokine expression. The detected proteins may serve as biomarkers to estimate the possibility of PVR formation and may help to invent personalized therapeutic strategies to slow down or prevent PVR.

Abstract
BACKGROUND Aging is a spontaneous and inevitable phenomenon of biology, which can lead to the gradual deterioration of tissues and organs. One of the age-related deterioration processes is immunosenescence, which leads to changes in the function of immune systems, including immune cells and associated cytokines. A proper modulation of immune responses can improve the age-related immunosenescence process and then reach healthy aging. Schisandra sphenanthera, a traditional Chinese medicine, has been used as both a medicine and a nutritional supplement for thousands of years. Anwulignan, a monomer compound of Schisandra sphenanthera lignans, has been reported to possess an immunomodulatory effect. Therefore, this study was designed to further explore whether Anwulignan could also modulate the immune functions in aging model mice and the underlying mechanism. METHODS D-galactose (D-gal) is often used as an inducer of immunosenescence in animals. In this study, a mice model was created by subcutaneous D-gal (220 mg kg-1) for successive 42 days. Then, the blood and spleen tissue samples were taken for the analysis and observation of cytokine levels, immunoglobulin levels, leukocyte numbers, and the phagocytic activity of macrophages, as well as the histological changes, the proliferation ability of lymphocytes, and the biochemical parameters in the spleen tissue. RESULTS Anwulignan significantly increased the serum levels of IL-2, IL-4, IFN-γ, lgG, lgM, and lgA, decreased the content of TNF-α and IL-6 in the aging mice, and increased the blood leukocyte number, the phagocytic activity, the lymphocyte proliferation, and the spleen index in vitro. Anwulignan also significantly increased the activities of SOD and GSH-Px, decreased the contents of MDA and 8-OHdG in the spleen tissue, up-regulated the expressions of Nrf2, HO-1, and Bcl2, down-regulated the expressions of Keap1, Caspase-3, and Bax in the spleen cells, and reduced the apoptosis of spleen lymphocytes. CONCLUSION Anwulignan can restore the immune function that is declined in D-gal-induced aging mice partly related to its antioxidant capacity by activating the Nrf2/ARE pathway and downstream enzymes, as well as its anti-apoptotic effect by regulating Caspase-3 and the ratio of Bcl2 to Bax in the spleen.

Abstract
This study aimed to establish a pure single-cell Theileria annulata-infected B cell line for the assessment of cytokine production in transformed and lipopolysaccharide (LPS)-stimulated cells. Several studies have aimed to identify cell surface markers in T. annulata-transformed cells; however, no information on cytokine production in these cells is available. To investigate the potential of the transformed cells to produce cytokines and their potential responses to antigen-stimulation, we purified mature B cells (CD21) from the whole blood of cattle experimentally infected with the T. annulata Kashi strain by magnetic separation. The purity and specificity of the established cell line was assessed by the identification of specific cell surface markers (CD21, IgM, and WC4) by flow cytometry analysis. The transcript levels of the cytokines IL1A, IL1B, IL2, IL4, IL6, IL8, IL10, IL16, LTA, TGFB1, TNFA, IFNA, and IFNB in transformed, buparvaquone (BW720c)-treated cells, and antigen-stimulated cells were analyzed by quantitative polymerase chain reaction (qPCR) using cDNA from these cells. A T. annulata-infected bovine B cell line was successfully established with a purity of ~98.8% (CD21). IL4 and IL12A were significantly (p < 0.01) upregulated in the transformed cells. In BW720c-treated transformed cells, IL12B, TGFB1, and IFNB were significantly (p < 0.01) upregulated. Notably, no significant (p > 0.05) upregulation of cytokines was observed in LPS-stimulated transformed cells. Moreover, IL1A, IL1B, IL8, and IL16 were significantly (p < 0.01) upregulated in LPS-stimulated B cells. Our data signify the potential use of this cell line for cytokine production, observance of immunoglobulins, and production of an attenuated vaccine against tropical theileriosis.

Abstract
Cytokines are among the most important effector and messenger molecules in the immune system. They profoundly participate in immune responses during infection and inflammation, protecting against or contributing to diseases such as allergy, autoimmunity, and cancer. Manipulating cytokine pathways, therefore, is one of the most effective strategies to treat various diseases. IL-10 family cytokines exert essential functions to maintain tissue homeostasis during infection and inflammation through restriction of excessive inflammatory responses, upregulation of innate immunity, and promotion of tissue repairing mechanisms. Their important functions in diseases are supported by data from many preclinical models, human genetic studies, and clinical interventions. Despite significant efforts, however, there is still no clinically approved therapy through manipulating IL-10 family cytokines. Here, we summarize the recent progress in understanding the biology of this family of cytokines, suggesting more specific strategies to maneuver these cytokines for the effective treatment of inflammatory diseases and cancers.

Abstract
BACKGROUND Pediatricians sometimes see patients with severe aseptic meningitis and prolonged fever or severe headache, or both. This condition generally has a good prognosis and is usually treated with supportive therapy. However, there is neither guideline nor consensus for the treatment of patients with severe aseptic meningitis. Here, we investigated the relationship between disease severity and biomarkers. METHODS The subjects were 32 children aged 0 to 14 years, 23 of whom had aseptic meningitis and 9 of whom were meningitis-free controls. Aseptic meningitis was retrospectively categorized into two subgroups, namely mumps meningitis (MM) and viral meningitis excluding that caused by mumps (EM). We defined a novel aseptic meningitis severity score (AMSS) from the signs and symptoms of aseptic meningitis and thus evaluated disease severity. We analyzed the profiles of cytokines in the patients' cerebrospinal fluid (CSF). RESULTS The AMSS in MM was significantly higher than that in EM. IL-4, IL-6, IL-8, IL-10, and G-CSF levels in MM and EM CSF were higher than those in control CSF. IFN-γ levels were higher in MM than in controls (p<0.01). IL-10 and IFN-γ levels in MM were higher than those in EM. CONCLUSIONS MM was more severe than EM. One likely reason is the higher CSF cytokine levels in MM. IFN-γ may be a potentially strong biomarker of MM severity. Our findings would help further understanding

Abstract
Chinese soft-shelled turtle, Pelodiscus sinensis, is widely cultured in East and Southeast Asian countries. It frequently encounters the stress of abrupt temperature changes, which leads to mass death in most cases. However, the mechanism underlying the stress-elicited death remains unknown. We have suspected that the stress impaired the immune function of Chinese soft-shelled turtle, which could result in the mass death, as we noticed that there was a clinical syndrome of infection in dead turtles. To test our hypothesis, we first performed bioinformatic annotation of several pro-inflammatory molecules (IL-1β, TNFα, IL-6, IL-12β) of Chinese soft-shelled turtle. Then, we treated the turtles in six groups, injected with Aeromonas hydrophila before acute cold stress (25 °C) and controls, after acute cold stress (15 °C) and controls as well as after the temperature was restored to 25 °C and controls, respectively. Subsequently, real-time PCR for several pro-inflammatory cytokines (IL-1β, TNFα, IL-6, IL-12β, IL-8 and IFNγ) was performed to assess the turtle immune function in spleen and intestine, 24 hours after the injection. We found that the mRNA expression levels of the immune molecules were all enhanced after acute cold stress. This change disappeared when the temperature was restored back to 25 °C. Our results suggest that abrupt temperature drop did not suppress the immune function of Chinese soft-shelled turtle in response to germ challenge after abrupt temperature drop. In contrast, it may even increase the expression of various cytokines at least, within a short time after acute cold stress.

Abstract
OBJECTIVE We aimed to investigate the expression of interleukin 12 (IL-12) family cytokines (IL-12, IL-23, IL-27 and IL-35) and their relevant cytokines (IFN-γ, IL-4, IL-17A and IL-10) in patients with chronic immune thrombocytopenia (cITP) as well as the effect of high-dose dexamethasone (HD-DXM) treatment on this expression. MATERIALS AND METHODS DXM was administered orally at a dose of 40 mg per day for 4 consecutive days to 38 patients with cITP. We measured the plasma levels of IL-12p70, IL-23, IL-27, IFN-γ, IL-4 and IL-17A before and after treatment and also in 36 matched healthy controls, by means of FlowCytomix™ technology. The plasma levels of IL-10 and IL-35 were measured by enzyme-linked immunosorbent assay. RESULTS Significantly higher plasma levels of IL-12p70, IL-23, IL-27, IFN-γ and IL-17A were observed in cITP patients than in controls (p < 0.01), and after HD-DXM treatment, these levels decreased significantly (p < 0.01). However, significantly lower plasma levels of IL-4, IL-10 and IL-35 were observed in cITP patients than in controls (p < 0.01); after the HD-DXM treatment, these levels had increased significantly in the cITP patients (p < 0.01). Moreover, the cytokine levels of patients who attained a complete response returned to the levels of normal controls (p > 0.05) but were not corrected in the patients who had no response (p < 0.01). CONCLUSIONS The patients with cITP had abnormal expression of the IL-12 family cytokines and their relevant cytokines levels, and HD-DXM treatment corrected the derangement of plasma cytokines. Measuring cytokine levels may help in the clinical assessment of cITP.

Abstract
NK cells are innate immune cells known for their cytolytic activities toward tumors and infections. They are capable of expressing diverse killer Ig-like receptors (KIRs), and KIRs are implicated in susceptibility to Crohn's disease (CD), a chronic intestinal inflammatory disease. However, the cellular mechanism of this genetic contribution is unknown. In this study, we show that the "licensing" of NK cells, determined by the presence of KIR2DL3 and homozygous HLA-C1 in host genome, results in their cytokine reprogramming, which permits them to promote CD4(+) T cell activation and Th17 differentiation ex vivo. Microfluidic analysis of thousands of NK single cells and bulk secretions established that licensed NK cells are more polarized to proinflammatory cytokine production than unlicensed NK cells, including production of IFN-γ, TNF-α, CCL-5, and MIP-1β. Cytokines produced by licensed NK augmented CD4(+) T cell proliferation and IL-17A/IL-22 production. Ab blocking indicated a primary role for IFN-γ, TNF-α, and IL-6 in the augmented T cell-proliferative response. In conclusion, NK licensing mediated by KIR2DL2/3 and HLA-C1 elicits a novel NK cytokine program that activates and induces proinflammatory CD4(+) T cells, thereby providing a potential biologic mechanism for KIR-associated susceptibility to CD and other chronic inflammatory diseases.

Abstract
Intelectin is a newly characterized gene family involved in early embryogenesis, host-pathogen interactions and iron metabolism. In this study, we searched the genomes of metazoans by extensive BLAST survey and found no intelectin homologs in invertebrate metazoans but 12 in amphioxus Branchiostoma floridae and 21 in ascidians Ciona intestinalis. Some ascidians oocyte cortical granule lectins (CGLs) have unknown insertion sequences between fibrinogen-related domain (FReD) and Intelectin Domain, the boundaries of which are equivalent to exon structures. In addition to ascidians intelectins/CGLs located in the base, phylogenetic tree comprises four main clades representing mammal, frog, fish, and amphioxus, indicating that intelectin genes undergo extensive lineage-specific duplication or gene conversion. However, genomic neighborhood surrounding analysis shows that clear proto-orthologies are difficult to be established among these counterparts. In addition, sequence comparison and phylogenetic analysis of FReDs from intelectins and other fibrinogen-like proteins from choanoflagellate, anemone, frog and human indicate FReDs of intelectins are unique. Likewise, these choanoflagellate and anemone genes may be close to intelectin gene.

Abstract
Primary dysmenorrhea is one of the most common gynecological complaints in young women, but potential peripheral immunologic features underlying this condition remain undefined. In this paper, we compared 84 common cytokine gene expression profiles of peripheral blood mononuclear cells (PBMCs) from six primary dysmenorrheic young women and three unaffected controls on the seventh day before (secretory phase), and the first (menstrual phase) and the fifth (regenerative phase) days of menstruation, using a real-time PCR array assay combined with pattern recognition and gene function annotation methods. Comparisons between dysmenorrhea and normal control groups identified 11 (nine increased and two decreased), 14 (five increased and nine decreased), and 15 (seven increased and eight decreased) genes with ≥2-fold difference in expression (P<0.05) in the three phases of menstruation, respectively. In the menstrual phase, genes encoding pro-inflammatory cytokines (IL1B, TNF, IL6, and IL8) were up-regulated, and genes encoding TGF-β superfamily members (BMP4, BMP6, GDF5, GDF11, LEFTY2, NODAL, and MSTN) were down-regulated. Functional annotation revealed an excessive inflammatory response and insufficient TGF-β superfamily member signals with anti-inflammatory consequences, which may directly contribute to menstrual pain. In the secretory and regenerative phases, increased expression of pro-inflammatory cytokines and decreased expression of growth factors were also observed. These factors may be involved in the regulation of decidualization, endometrium breakdown and repair, and indirectly exacerbate primary dysmenorrhea. This first study of cytokine gene expression profiles in PBMCs from young primary dysmenorrheic women demonstrates a shift in the balance between expression patterns of pro-inflammatory cytokines and TGF-β superfamily members across the whole menstrual cycle, underlying the peripheral immunologic features of primary dysmenorrhea.

Abstract
It remains unknown whether newly identified anti-inflammatory/immunosuppressive cytokine interleukin-35 (IL-35) is different from other anti-inflammatory cytokines such as IL-10 and transforming growth factor (TGF)-β in terms of inhibition of inflammation initiation and suppression of full-blown inflammation. Using experimental database mining and statistical analysis methods we developed, we examined the tissue expression profiles and regulatory mechanisms of IL-35 in comparison to other anti-inflammatory cytokines. Our results suggest that in contrast to TGF-β, IL-35 is not constitutively expressed in human tissues but it is inducible in response to inflammatory stimuli. We also provide structural evidence that AU-rich element (ARE) binding proteins and microRNAs target IL-35 subunit transcripts, by which IL-35 may achieve non-constitutive expression status. Furthermore, we propose a new system to categorize anti-inflammatory cytokines into two groups: (1) the house-keeping cytokines, such as TGF-β, inhibit the initiation of inflammation whereas (2) the responsive cytokines including IL-35 suppress inflammation in full-blown stage. Our in-depth analyses of molecular events that regulate the production of IL-35 as well as the new categorization system of anti-inflammatory cytokines are important for the design of new strategies of immune therapies.

Abstract
Modulation of host responses is an important strategy by which parasites ensure successful establishment and persistence. Host counteraction against this modulation may be required for the host to develop resistance to infection. In this pilot study, experimental infection of dogs with Echinococcus granulosus induced a strong polarization of the cytokine response towards a Th2 phenotype. Consecutive rounds of infection and cure induced resistance to infection resulting in a dramatically lower parasite burden. Repeatedly-infected resistant dogs also lost immune polarization and developed a balanced Th1/Th2 response. No major differences were observed in the production of regulatory cytokines (IL-10, TGF-β) between dogs with high parasite load and dogs with only few intestinal parasites. These results suggest that E. granulosus-driven immunomodulation contributes to successful infection in the definitive host. This information might be relevant for the development of more effective vaccines against this stage of the parasite.

Abstract
After exposure to ozone, humans develop neutrophil infiltration of the nasal mucosa. To investigate the events contributing to inflammatory cell recruitment in the nasal mucosa we exposed 10 healthy nonsmoking volunteers to 400 ppb ozone or filtered air for 2h at rest on two separate occasions. Nasal biopsies were performed 6h after ozone/filtered air exposure. The nasal biopsies were embedded in glycol mathacrylate and immunostained for inflammatory cells, including neutrophils, mast cells, total T-cells (CD3), T-cell subsets CD8 and CD4, macrophages, eosinophils adhesion molecules (P-selectin, E-selectin, ICAM-1, VCAM-1), cytokines (TNF-α, IL-1β, GM-CSF, IL-6), chemokines (IL-8 and RANTES), and nuclear factor NF-κB. No significant changes were seen in the number of T-cells, and T-cell subsets, eosinophils, macrophages, or percentages of vessels expressing P-selectin, VCAM-1, GM-CSF, IL-6 and RANTES in the biopsies. The number of neutrophils and mast cells in the submucosa was significantly higher after ozone exposure (p=0.009 and p=0.005 respectively). The percentage of vessels expressing E-selectin (p=0.01), ICAM-1 (p=0.005), IL-8 (p=0.02), TNF-α (p=0.02), IL-1β (p=0.009), and NF-κB (p=0.05) increased significantly after ozone exposure as compared to filtered air exposure. Exposure of normal subjects to ozone increases the expression of proinflammatory cytokines resulting in upregulation of IL-8 and adhesion molecules via activation of NF-κB, leading to neutrophil inflitration in the nasal mucosa.

Abstract
There is a growing body of evidence implicating inflammatory cytokines and brain-derived neurotropic factor (BDNF) in the generation of migraine pain. No previous study evaluated BNDF levels during migraine attacks and there are conflicting results regarding tumor necrosis factor-alpha (TNF-alpha) serum levels. This study compared serum levels of TNF-alpha, soluble TNF receptors 1 and 2 (sTNF-R1 and sTNF-R2), and BDNF during migraine attacks and in headache-free periods. Nine patients with episodic migraine were clinically evaluated during a migraine attack and in a headache-free period. Blood sample of each patient in both occasions was collected and all serum was submitted to TNF-alpha, sTNF-R1, sTNF-R2, and BDNF determination by ELISA. There was no significant difference in the serum levels of TNF-alpha, sTNF-R1 and sTNF-R2 in migraine attack period and headache-free period. BDNF serum levels were significantly higher during migraine attack than in pain-free period. This is the first report showing that BDNF serum levels increase during migraine attack. This reinforces the view that BDNF may be implicated in the physiopathology of migraine.

Abstract
Discussions about various physiological and pathological processes commonly debate the role of mediators known as cytokines. Also, several drugs are analogues of cytokines or are aimed at blocking the actions of specific cytokines to modify diseases processes. So, increasingly, healthcare professionals need to have a working knowledge of cytokines. With this in mind, here, we briefly describe the types and actions of cytokines, some aspects of their role in certain diseases and the use of drugs to augment or block their action.

Abstract
Genistein (4',5,7-trihydroxyisoflavone) is the most abundant isoflavone found in the soybean that exhibits an anti-inflammatory effect. The present study was designed to examine the effects of genistein on expression levels of hemolysate-induced proinflammatory and adhesion molecules in SD rat brain microvascular endothelial cells (BMECs). Genistein treatment attenuated hemolysate-induced nuclear factor-kappa B (NF-kappaB) p65 translocation in BMECs. In addition, genistein suppressed the expression levels of tumor necrosis factor-alpha (TNF-alpha), monocyte chemoattractant protein 1 (MCP-1), and intercellular adhesion molecule-1 (ICAM-1), but not vascular cell adhesion molecule-1 (VCAM-1). The inhibitory rate of 50 pM genistein for TNF-alpha, MCP-1 and ICAM-1 was 65.4%, 60.5% and 54.9% respectively. These inhibitory effects of genistein on proinflammatory and adhesion molecules were not due to decreased BMEC viability as assessed by MTT test. Taken together the present study suggests that genistein suppresses expression levels of hemolysate-induced pro-inflammatory and adhesion molecules in cerebral endothelial cells.

Abstract
In animal models of diet-induced obesity, the activation of an inflammatory response in the hypothalamus produces molecular and functional resistance to the anorexigenic hormones insulin and leptin. The primary events triggered by dietary fats that ultimately lead to hypothalamic cytokine expression and inflammatory signaling are unknown. Here, we test the hypothesis that dietary fats act through the activation of toll-like receptors 2/4 and endoplasmic reticulum stress to induce cytokine expression in the hypothalamus of rodents. According to our results, long-chain saturated fatty acids activate predominantly toll-like receptor 4 signaling, which determines not only the induction of local cytokine expression but also promotes endoplasmic reticulum stress. Rats fed on a monounsaturated fat-rich diet do not develop hypothalamic leptin resistance, whereas toll-like receptor 4 loss-of-function mutation and immunopharmacological inhibition of toll-like receptor 4 protects mice from diet-induced obesity. Thus, toll-like receptor 4 acts as a predominant molecular target for saturated fatty acids in the hypothalamus, triggering the intracellular signaling network that induces an inflammatory response, and determines the resistance to anorexigenic signals.

Abstract
The immunologic characterization of chronic idiopathic urticaria (CIU), mainly regarding cytokine profile needs more investigation. We examined circulating inflammatory cytokine levels, T-cell induced secretion, and cytokine mRNA expression in patients with CIU subjected to the intradermal autologous serum skin test (ASST). Increased levels of circulating pro-inflammatory cytokines, such as TNF-alpha, IL-1beta, IL-12p70, and IL-6 have been observed in most of patients with CIU, together with an enhancement of IL-2 secretion following T-cell stimulation. Highlighting the inflammatory profile in CIU found in ASST positive, is the enhanced B-cell proliferative responsiveness and increased IL-17 secretion levels. ASST-positive patients also exhibited impaired IL-4 secretion associated with increased IL-10 production. Altered cytokine expression in patients with ASST-negative, was the down-modulation of spontaneous IL-10 mRNA expression levels in peripheral blood mononuclear cells. Our findings support the concept of immunologic dysregulation in CIU, revealing a systemic inflammatory profile associated with disturbed cytokine production by T cells, mainly related to IL-17 and IL-10 production.

Abstract
More than 20 yrs ago, T-helper lymphocytes were divided into Th1 and Th2 subsets on the basis of their cytokine production. The pro-inflammatory Th1 subset was considered predominant in inflammatory arthritis, but evidence for this notion was incomplete, and some called into question the role of helper T cells. The identification of a novel T cell subset, Th17 cells, which appears to be critical for several forms of autoimmune inflammation, including arthritis, requires a reconsideration of arthritis pathogenesis and the role of T cells. This review deals with several of the newly described ('big number') cytokines which are involved in the differentiation and action of Th17 cells, and pays particular attention to the pathogenesis of spondyloarthritis because of the implication of the same cytokine networks in psoriasis and inflammatory bowel disease. The role of dendritic cells as coordinators of T cell differentiation in response to pathogen-derived signals in also emphasized.

Abstract
Asthma is a chronic inflammatory disease of the airways characterized by reversible airway obstruction, airway hyperreactivity, and remodeling of the airways. The incidence of asthma is on the rise despite ongoing intensive asthma research. Artemisia iwayomogi, a member of the Compositae, is a perennial herb easily found around Korea and has been used as a traditional anti-inflammatory medicine in liver diseases. We investigated suppressive effects of AIP1, a water-soluble carbohydrate fraction from A. iwayomogi on ovalbumin-induced allergic asthma in BALB/c mice and studied the possible mechanisms of its anti-allergic action. AIP1 significantly reduced pulmonary eosinophilia and Th2 cytokine expression in the lungs as well as serum IgE levels. Flow cytometric analysis of lung-infiltrating cells showed that the surface levels of CD11c and MHC II in CD11c+MHC II+ cells, potent dendritic cells, decreased in animals treated with AIP1. Expression of TNF-alpha, one of several proinflammatory cytokines released into the airway during episodes of asthma, was down-regulated by AIP1 injection, suggesting that reduced expression of TNF-alpha could account for the suppression of pulmonary eosinophilia and Th2-type cytokine production by AIP1.

Abstract
We have generated a novel mouse model harboring the in-frame rearranged TCRValpha specific for invariant NKT (iNKT) cells (Valpha14-Jalpha18) on one allele by crossing the mouse cloned from NKT cells with wild-type mice. This genomic configuration would ensure further rearrangement and expression of TCRValpha14-Jalpha18 under the endogenous promoters and enhancers. Mice harboring such an in-frame rearranged TCRValpha (Valpha14-Jalpha18 mouse) possessed an increase in iNKT cells in the thymus, liver, spleen, and bone marrow. Intriguingly, both Th1- and Th2-type cytokines were produced upon stimulation with alphaGalactosylceramide, an agonist of iNKT cells, and the IgE level in the serum remained unaffected in the Valpha14-Jalpha18 mouse. These features markedly distinguish the nature of iNKT cells present in the Valpha14-Jalpha18 mouse from that of iNKT cells found in the Valpha14-Jalpha18 transgenic mouse. Besides these, the expression of TCRVgammadelta cells remained intact, and the use of the TCRVbeta repertoire in iNKT cells was highly biased to TCRVbeta8 in the Valpha14-Jalpha18 mouse. Furthermore, alphaGalactosylceramide-CD1d dimer-reactive immature iNKT cells expressed less Rag2 as compared with the conventional immature T cells at the positive selection stage. Cell cycle analysis on the thymocytes revealed that no particular subset proliferated more vigorously than the others. Crossing the Valpha14-Jalpha18 mouse with the CD1d knockout mouse revealed a novel population of iNKT cells whose coreceptor expression profile was similar to that assigned to iNKT precursor cells. These mice will be useful for the study on the development of iNKT cells as well as on their functions in the immune system.

Abstract
The aim of this study was to explore the relationship and interpret the clinical importance of acute physiology and chronic health evaluation III (APACHE III) and levels of cytokines in patients with systemic inflammatory response syndrome (SIRS) after coronary artery bypass grafting (CABG) with or without cardio-pulmonary bypass (CPB) to see if they are beneficial for evaluating the seriousness of SIRS. The data suggested that the APACHE III score and levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1beta), and soluble interleukin-2 receptor (sIL-2R) were significantly higher after conventional CABG (CCABG) than after off-pump coronary artery bypass grafting (OPCAB) (p<0.05). With an increase in the APACHE III score, the levels of IL6, IL8, TNF-alpha, IL-1beta, and sIL-2R and the morbidity of multiple organ dysfunction syndrome (MODS) increased gradually (p<0.01), while the level of IL2 decreased (p<0.01). Stepwise regression analysis showed that IL-1beta, IL6, IL8, and sIL-2R levels had significant influences on the APACHE III score (p<0.05). The APACHE III score and levels of IL6, IL8, TNF-alpha, IL-1beta, and sIL-2R were significantly higher in the MODS group than in the non-MODS group (p<0.05), but the level of IL2 was significantly lower in the MODS group (p = 0.04). In conclusion, despite comparable surgical trauma, we believe that CPB is one of the most important factors responsible for stimulating an inflammatory response. SIRS after OPCAB was clearly mitigated compared with CCABG. Determination of the APACHE III score and plasma IL-1beta, IL6, IL8 and sIL-2R concentrations might be helpful for evaluating the severity of SIRS following CABG and making a prognosis.

Abstract
Although in broad terms the avian immune response is remarkably similar to that of mammals, when one looks at specifics birds have a different repertoire of immune organs, cells and molecules compared to those characterized in mammals. Birds lack organized lymph nodes, yet have the Bursa of Fabricius. Birds lack neutrophils and functional eosinophils, yet have a distinct group of polymorphonuclear granulocytes known as heterophils. Birds also have a different repertoire of cytokines, chemokines, Toll-like receptors, defensins and integrins, as detailed in this review.

Abstract
The interactions between cytokines and their complementary receptors are the gateways to properly understand a large variety of cytokine-specific cellular activities such as immunological responses and cell differentiation. To discover novel cytokine-receptor interactions, an advanced support vector machines (SVMs) model, CytoSVM, was constructed in this study. This model was iteratively trained using 449 mammal (except rat) cytokine-receptor interactions and about 1 million virtually generated positive and negative vectors in an enriched way. Final independent evaluation by rat's data received sensitivity of 97.4%, specificity of 99.2% and the Matthews correlation coefficient (MCC) of 0.89. This performance is better than normal SVM-based models. Upon this well-optimized model, a web-based server was created to accept primary protein sequence and present its probabilities to interact with one or several cytokines. Moreover, this model was applied to identify putative cytokine-receptor pairs in the whole genomes of human and mouse. Excluding currently known cytokine-receptor interactions, total 1609 novel cytokine-receptor pairs were discovered from human genome with probability ∼80% after further transmembrane analysis. These cover 220 novel receptors (excluding their isoforms) for 126 human cytokines. The screening results have been deposited in a database. Both the server and the database can be freely accessed at http://bioinf.xmu.edu.cn/software/cytosvm/cytosvm.php.

Abstract
While IL-18 synergizes with IL-12 to induce a Th1 immune response, it also promotes a Th2 response. Here we investigate the modulatory role of IL-18 on the Th1/Th2 cytokine response. The injection of alpha-galactosylceramide (alpha-GalCer), a ligand for NKT cells, elevated mouse serum levels of both IFN-gamma and IL-4. When the mice were treated 2 h before alpha-GalCer challenge with IL-18, IFN-gamma production but not IL-4 production was remarkably up-regulated. In contrast, pretreatment with IL-18 6 h before the challenge enhanced IL-4 production. However, this IL-18-enhanced IL-4 production was not elicited in mice injected with anti-CD3 Ab. Liver mononuclear cells (MNC) produced a similar cytokine production pattern when MNC from mice treated with IL-18 either 2 h or 6 h before challenge were stimulated with alpha-GalCer in vitro. Expression of SOCS1 and SOCS3 was notably up-regulated in the liver MNC from mice pretreated 6 h before with IL-18; in particular, SOCS3 expression was confined to the liver NKT cells. Inhibition of SOCS3 by RNA interference up-regulated the phosphorylation of STAT3 and suppressed in vitro IL-4 production by IL-18-primed liver MNC stimulated with alpha-GalCer, but it did not affect IFN-gamma production. These results suggest that IL-18 time-dependently modulates Th1/Th2 cytokine production in ligand-activated NKT cells by regulating/inducing SOCS3 expression.

Abstract
IL-19 and IL-20 are two cytokines that were discovered in 2000 and 2001, respectively. Based on the structure and location of their genes, their primary and secondary protein structures and the used receptor complexes, they were classified with IL-10, IL-22, IL-24, IL-26, IL-28 and IL-29 in the IL-10 family of cytokines, and form a subgroup with IL-24 within this family. IL-19 and IL-20 are produced by monocytes as well as non-immune tissue cells under inflammatory conditions. IL-19 and IL-20 act via a receptor complex that consists of the IL-20R1 and IL-20R2 chains. IL-20 is additionally able to signal via a second receptor complex (IL-22R1/IL-20R2). It is controversial whether or not IL-19 and IL-20 regulate the function of immune cells. However, the expression of their receptors aliments the perception that the cells of the skin, lungs and reproductive organs as well as various glands are major targets of these mediators. Results from animal experiments and massively increased expression of these mediators in human inflamed tissues support the assumption that they play an important role in the pathogenesis of a few inflammatory diseases. For this reason, the authors have reviewed the facts known at present regarding these cytokines and postulate that IL-19 and IL-20 are pharmacologically interesting distal elements of an inflammatory cascade.

Abstract
The pathogenesis of pulmonary fibrosis is poorly understood. Although inflammation has been presumed to have an important role in the development of fibrosis this has been questioned recently, particularly with regard to idiopathic pulmonary fibrosis (IPF). It is, however, increasingly recognized that the polarization of the inflammatory response toward a type 2 phenotype supports fibroproliferation. Increased attention has been on the role of noninflammatory structural cells such as the fibroblast, myofibroblast, epithelial cell, and endothelial cells. Furthermore, the origin of these cells appears to be multifactorial and includes resident cells, bone marrow-derived cells, and epithelial to mesenchymal transition. Increasing evidence supports the presence of vascular remodeling in fibrotic lung disease, although the precise role in the pathogenesis of fibrosis remains to be determined. Therefore, the pathogenesis of pulmonary fibrosis is complex and involves the interaction of multiple cell types and compartments within the lung.

Abstract
OBJECTIVE Erythropoietin (EPO) has been shown to not only have cardioprotective effects but also attenuate autoimmune diseases. In the present study, we investigated the effect of EPO on cardiac inflammation and function, inflammatory cell infiltration, and cytokine expression in a rat model of experimental autoimmune myocarditis (EAM). METHODS AND RESULTS Male Lewis rats (6-8 weeks old) were immunized on day 0 with porcine cardiac myosin to establish EAM. The rats were subcutaneously administered either vehicle (saline) or human recombinant EPO (6,000 U/kg, 3 days/week) from day 0 to 20, and they were evaluated on day 21. In the EPO group, the inflammation area and heart weight/body weight ratio were significantly attenuated as compared with those in the vehicle group. Blood pressure and cardiac function were also improved in the EPO group. Immunohistochemistry revealed that EPO decreased the infiltration of macrophages and CD4 T cells, and degranulated mast cells in the myocardium. Real-time RT-PCR analysis demonstrated that inflammatory cytokine expression in the myocardium and lymphocytes was suppressed in the EPO group. However, in vitro experiments showed that EPO had no effect on antigen-induced proliferation and cytokine expression in lymphocytes. CONCLUSION EPO attenuates inflammatory cell infiltration and cytokine expression, and it improves cardiac function and reduces cardiac inflammation in EAM. This beneficial effect of EPO is unlikely to arise from a direct anti-inflammatory action on lymphocytes. These findings suggest the therapeutic potential of EPO for the treatment of myocarditis.

Abstract
The macrophage migration inhibitory factor (MIF) has been identified from some vertebrates and invertebrates. MIF is related to inflammation, tumor growth, and angiogenesis in vertebrates. Here, we report the molecular characterization of a homologue of MIF from partially fed Haemaphysalis longicornis. The sequence analysis of the H. longicornis MIF (HlMIF) indicated that its deduced amino acid sequence has an identity of 77% with the MIF of the tick Amblyomma americanum. Western blot analysis using the anti-His-HlMIF antibody showed that HlMIF was up-regulated during blood feeding. Immunohistochemistry showed that the endogenous HlMIF in partially fed ticks was localized to the midgut and epidermal cells. Moreover, the functional assay revealed that the GST-HlMIF inhibited the migration of human monocytes. In conclusion, we consider that HlMIF may facilitate blood feeding by inhibiting host macrophage migration to the feeding lesion or may participate in the proliferation and differentiation of cells in the tick body.

Abstract
The current research concerned in the cloning, sequencing and phylogenetic analysis of inflammatory cytokine (IL-1alpha, IL-1beta, IL-6 and TNF-alpha) genes from swamp buffalo and two bubaline breeds, CB (cross between swamp and riverine type buffalo) and the Bulgarian Murrah buffalo. Multiple sequence comparison showed a high homology between the bubaline breeds, which ranged from 99.3% to 100.0% similarity, whereas from 98.6% to 99.0% compared to cattle. The phylogenetic analysis had confirmed and justified the degree of relationship between these bubaline species and their distinctness to each other by the bootstrap value (%) generated. These findings were discussed with particular attention to the diversity of the inflammatory cytokine proteins within closely related species. The result of this study concluded that a small difference in the cytokine structures might be the reason behind or has a contributory factor on the previous reports about the existence of disease resistance. However, in-depth study is necessary to further qualify these findings.

Abstract
One of the factors involved in the pathogenesis of recurrent aphthous stomatitis (RAS) is a cell-mediated immune response in which several cytokines seem to play a major role. The aim of this study was to detect, enumerate and characterize T helper cells which are secreting type 1 cytokines (interleukin [IL]-2, IL-12, interferon [IFN]-gamma, and tumor necrosis factor [TNF]-alpha) and type 2 cytokines (IL-4, IL-5, IL-6, and IL-10) in the peripheral blood of patients with RAS. Thirty-two patients in the active phase of RAS (14 men and 18 women) and 40 healthy individuals participated in the study. T helper (T) cells were detected and characterized using Elispot assay. T cells secreting IL-2, IL-12 or IFN-gamma were increased in patients with RAS compared with the controls (p < 0.05, p < 0.001 and p < 0.001, respectively). T cells secreting TNF-alpha in RAS patients and controls were not statistically different (p > 0.05). T cells secreting IL-10 were increased in patients with RAS compared with the controls (p < 0.05). T cells secreting IL-4 were decreased in patients with RAS compared with the controls (p < 0.001), No statistical difference was observed between T cells secreting IL-5 or IL-6 in patients with RAS and controls. Our findings suggest that the increased numbers of T cells secreting type 1 cytokines may influence the immune response against RAS. Whether this action is of etiological importance or epigenetic phenomenon is a question that needs to be answered.

Abstract
Studies concerned evaluation of differences between parameters of cell-mediated immunity in mice, induced with whole-cell and acellular pertussis vaccines with subsequent challenge with B. pertussis strains harbouring different ptxS1/prn allele genes. In the study, concentrations of IFN-gamma/Il-2 and 1l-4/Il-5 in supernatants of cultured mice splenocytes have been determined to evaluate differences in Th1 or Th2 lymphocytes subpopulation response. Simultaneously, studies of intracellular expression of genes encoding of Il-2, Il-12, IFN-gamma and Il-4, Il-5, Il-10, Il-13 in mice splenocytes, and genes encoding factors involved in inflammatory process in the lung tissue (GM-CSF, TNF-alpha, Il-1beta, Il-6 i TGF-beta) have been performed on RNA level. The obtained results, confirmed high polarization of immunological response toward Th1 in mice immunized with DTP vaccine with whole-cell pertussis component, and toward Th2 in mice immunized with acellular pertussis vaccine. Inflammatory process in the lung tissue was more pronounced in animals immunized with whole-cell pertussis vaccine. There were no quantitative differences of analysed factors involved in the immune response among mice challenged B. pertussis strains containing different ptxS1/prn composition.

Abstract
We conducted a prospective cohort study in Leyte, the Philippines, among 611 Schistosoma japonicum-infected participants 7-30 years old, all of whom were treated with praziquantel at baseline. To detect hepatic fibrosis, abdominal ultrasound was performed at baseline and 12 months after treatment. Stool for assessment of S. japonicum infection was collected at baseline and at 3, 6, 9, and 12 months after treatment. Cytokines (interleukin [IL]-4, IL-5, IL-10, IL-13, tumor necrosis factor- alpha , and interferon- gamma ) produced by peripheral-blood mononuclear cells in response to soluble worm antigen preparation (SWAP), soluble egg antigen (SEA), and control medium were measured once 4 weeks after treatment. IL-4 to SWAP and IL-10 to both SWAP and SEA were associated with the presence of baseline fibrosis after adjustment for potential confounding variables (P<.03, for all). In participants with fibrosis at baseline, IL-4 to SWAP and IL-5 and IL-13 to both SWAP and SEA were associated with persistent fibrosis at 12 months after treatment (P<.05, for all). Males showed consistently stronger T helper 2 (Th2) cytokine responses to both SWAP and SEA than did females (P<.02, for all). These results suggest an independent role for Th2-biased cytokine responses to S. japonicum antigens in persistent hepatic fibrosis and indicate that Th2 cytokines may contribute to the male-biased prevalence of fibrosis.

Abstract
Hepatic stellate cells (HSCs) play a pivotal role in hepatic fibrogenesis, and are considered a cellular target for therapeutic intervention. We recently established that a 2.2-kb hGFAP (human glial fibrillary acidic protein) promoter could be used to specifically target cultured HSCs. In the current study, we aimed to investigate whether the same transgene (2.2-kb hGFAP-lacZ) can be used as a biomarker for studying the inhibition of HSC activation. HSC-T6 cells stably transfected with the transgene were treated with two natural anti-fibrotic compounds, epigallocatechin gallate (EGCG) and genistein separately. Results showed that both transgenic beta-galactosidase activity and endogenous GFAP expression (mRNA and protein) were attenuated by EGCG or genistein treatment in a dose- and time-dependent manner. Our data further demonstrated that the suppression of fibrogenic end-points was primarily mediated through the inhibition of AP-1 signaling (and to a lesser degree through the NFkappaB pathway) onto the GFAP promoter. In conclusion, the current findings provide a proof-of-concept for using GFAP for studying HSC activation and inhibition. It could be envisioned that a HSC-based high-throughput system can be constructed using the GFAP promoter in conjunction with a real-time reporter for the screening of anti-fibrotic and anti-inflammatory agents.

Abstract
UNLABELLED Mda-7 or IL-24, a novel member of the IL-10 cytokine family has growth inhibitory effect on several human cancers including melanoma via selective apoptosis. Expression of IL-24 could be induced in human PBMC by treatment with phytohaemagglutinin, lypopolisaccharide, IL-4 or influenza A virus infection. MATERIALS AND METHODS Human PBMC were stimulated with staphylococcal strains originating from clinical specimens, and the appearance of IL-24 at the level of transcription and translation was followed by RT-nested PCR and Western blot assays. RESULTS All staphylococcal strains induced IL-24 mRNA. Staphylococci, pathogenic or not, did induce the production of IL-24 in PBMC, but there was a difference between the different staphylococcal strains in their effect on the production of the IL-24 protein. CONCLUSIONS The pathogenic S. aureus or bacteria belonging to the normal flora of the skin (S. epidermidis and S. saprophyticus) as factors stimulating the production of the Mda-7 protein may be a crucial lead in the investigation of different skin lesions.

Abstract
In recent years the knowledge of avian cytokines has advanced and new data are continuously added. Nevertheless, some discontinuities persist and the correlations between molecular and functional levels are not completely clear. Most of the studies are focused on chicken, and comparative aspects with other avian groups are limited. The existence of T1 and T3 avian cytokines was assessed long ago and the recent relevant demonstration of the existence of T2 cytokines in birds is a further step in depicting a more complete view on avian immunology. The progressive knowledge of avian cytokines can hopefully help in developing new strategies in prophylaxis and therapy of avian diseases, not always completely controlled due to the emergence of more pathogenic strains.

Abstract
Although human plasma represents an attractive sample for disease biomarker discovery, the extreme complexity and large dynamic range in protein concentrations present significant challenges for characterization, candidate biomarker discovery, and validation. Herein we describe a strategy that combines immunoaffinity subtraction and subsequent chemical fractionation based on cysteinyl peptide and N-glycopeptide captures with two-dimensional LC-MS/MS to increase the dynamic range of analysis for plasma. Application of this "divide-and-conquer" strategy to trauma patient plasma significantly improved the overall dynamic range of detection and resulted in confident identification of 22,267 unique peptides from four different peptide populations (cysteinyl peptides, non-cysteinyl peptides, N-glycopeptides, and non-glycopeptides) that covered 3,654 different proteins with 1,494 proteins identified by multiple peptides. Numerous low abundance proteins were identified, exemplified by 78 "classic" cytokines and cytokine receptors and by 136 human cell differentiation molecules. Additionally a total of 2,910 different N-glycopeptides that correspond to 662 N-glycoproteins and 1,553 N-glycosylation sites were identified. A panel of the proteins identified in this study is known to be involved in inflammation and immune responses. This study established an extensive reference protein database for trauma patients that provides a foundation for future high throughput quantitative plasma proteomic studies designed to elucidate the mechanisms that underlie systemic inflammatory responses.
