Abstract
CD4+ TH cells develop into subsets that are specialized in the secretion of particular cytokines to mediate restricted types of inflammation and immune responses. Among the subsets that promote development of allergic inflammatory responses, IL-9-producing TH9 cells are regulated by a number of transcription factors. We have previously shown that the E26 transformation-specific (Ets) family members PU.1 and Ets translocation variant 5 (ETV5) function in parallel to regulate IL-9. In this study we identified a third member of the Ets family of transcription factors, Ets-related gene (ERG), that mediates IL-9 production in TH9 cells in the absence of PU.1 and ETV5. Chromatin immunoprecipitation assays revealed that ERG interaction at the Il9 promoter region is restricted to the TH9 lineage and is sustained during murine TH9 polarization. Knockdown or knockout of ERG during murine or human TH9 polarization in vitro led to a decrease in IL-9 production in TH9 cells. Deletion of ERG in vivo had modest effects on IL-9 production in vitro or in vivo. However, in the absence of PU.1 and ETV5, ERG was required for residual IL-9 production in vitro and for IL-9 production by lung-derived CD4 T cells in a mouse model of chronic allergic airway disease. Thus, ERG contributes to IL-9 regulation in TH9 cells.

Fahmawi A, Khalifeh MS, Alzoubi KH, Rababa'h AM. The Effects of Acute and Chronic Sleep Deprivation on the Immune Profile in the Rat. Curr Mol Pharmacol 2023; 16:101-108.

Abstract
BACKGROUND Acute and chronic sleep deprivation present many health-related problems in modern societies, mainly concerning the immune system. Immune factors, particularly the interleukins, regulate sleep and, therefore, may be altered by sleep deprivation (SD). OBJECTIVES We aimed to investigate the possible effects of acute and chronic sleep deprivation on selected cytokines, including interleukins (IL-1β, IL-9, IL-17, and IL-23) and tumor necrosis factor- alpha (TNF-α). METHODS The animals were grouped into acute sleep-deprived (SD; for 24 hours) and chronic sleep-deprived (8 hours a day for 10, 20, and 30-days). The SD was induced using the multipleplatforms model. The serum levels of cytokines were measured using commercially available ELISA. RESULTS The serum levels of IL-1β were significantly reduced after acute SD, whereas they were increased after 20-days of chronic SD. The IL-9 levels were reduced after acute SD, increased after 10-days of SD, and reduced again after 30-days of SD. Conversely, the levels of IL-23 were not changed after acute SD, reduced after 10 days of SD, and increased after 30-days of SD. Levels of TNF-α were not changed after acute SD, whereas they were increased after 20 and 30- days of SD. CONCLUSION In conclusion, both acute and chronic SD distinctly disturb the immune profile, which might result in the emergence of various pathologies presented during sleep deprivation.

Abstract
BACKGROUND Epithelial Ovarian cancer (EOC) is the leading cause of death associated with gynecologic tumors. Because the disease is asymptomatic in early-stage, the majority of patients are not diagnosed until late stages, highlighting the need for the development of novel diagnostic biomarkers. Mediators of tumoral microenvironment may affect EOC progression and resistance to treatment. AIM OF THE STUDY Analysis of serum proteins to identify a panel of theranostic biomarkers for EOC. PATIENTS AND METHODS Serum levels of 65 analytes were determined in EOC patients, and healthy controls with the ProcartaPlex Human Immune Monitoring 65-Plex Panel. RESULTS Twenty-one analytes: 7 cytokines (IFN-γ, IL-12p70, IL-13, IL-18 and TSLP), 7 chemokines (Eotaxin, eotaxin-2, IP-10, BLC, I-TAC, SDF-1α, and fractalkine), 2 growth factors (MMP-1, VEGF-α), and 5 soluble receptors (APRIL, CD40L, TWEAK, CD30 and TNFRII; were significantly differentially expressed between the two groups. ROC curves showed that only seven of them (IL-9, TNF-α, Eotaxin, IP-10, BLC, Fractalkine, and Tweak) had AUC values greater than 0.70 and thus had potential clinical utility. Moreover, five cytokines: IFN-γ, IL-1 β, IL-8, MIP-1β, and TNF-α are positively associated with patients who developed resistance to taxol-platinum-based chemotherapy (CT). CONCLUSION This study has revealed a first panel of 7 analytes (IL-9, TNF-α, Eotaxin, IP-10, BLC, Fractalkine and Tweak) that can be used for early detection of EOC and a second panel of five cytokines (IFN-γ, IL-1β, IL-8, MIP-1β, TNF-α) that can help clinicians to identify EOC patients who are at higher risk to develop resistance to CT of EOC.

Abstract
BACKGROUND Psoriasis is an autoimmune and autoinflammatory disorder that has a significant impact on patient quality of life. The aim of the study was to assess the immune profiles of patients with psoriasis with multiple cytokine analysis. MATERIAL AND METHODS Fifty-two male psoriatic patients and 24 healthy male volunteers were recruited. Granulocyte-macrophage colony-stimulating factor (GM-CSF), interferon gamma (IFN-gamma), interleukin (IL)-1 beta, IL-2, Il-4, IL-5, IL-6, IL-9, IL-10, IL-12p70, IL-13, IL-17A, IL-18, IL-21, IL-22, IL-23, IL-27, and tumor necrosis factor (TNF)-alpha were measured in patients' serum with a Th1/Th2/Th9/Th17/Th22/Treg Cytokine 18-Plex Human ProcartaPlex Panel, based on Luminex xMAP technology. RESULTS The median fluorescence intensities of serum GM-CSF, IL-2, IL-5, IL-10, IL-13, IL-17A, IL-21, and IL-22 were not intensive enough to calculate the cytokine concentration. We observed elevated levels of IL-6 (P=0.001) and IL-9 (P=0.003) in patients, compared with the control group. The levels of IL-1beta (P=0.008) and IL-27 (P=0.006) were decreased. In patients with psoriatic arthritis, we noticed a decreased level of IL-9 compared with that in patients without arthritis (P=0.034). The levels of IL-12 (P<0.05) and IL-18 (P<0.05) correlated positively with the Psoriasis Area and Severity Index. We found negative correlations of IL-9 (P<0.05), IL-12 (P<0.05), and IL-23 (P<0.05) with the age of psoriatic patients; IL-12 (P<0.05) and IL-23 (P<0.05) with psoriasis duration; and IL-6 (P<0.05) and IL-9 (P<0.05) with the Nail Psoriasis Severity Index. CONCLUSIONS Multiple cytokine analysis seems to be an important form of individual immune profile assessment before treatment selection.

Abstract
OBJECTIVE To investigate the effects of interleukin-9 (IL-9) in the activation of hepatic stellate cells (HSCs) in mice infected with Schistosoma japonicum. METHODS Primary HSCs were isolated from mice 7 weeks post-infection with S. japonicum using the in situ liver perfusion and density gradient centrifugation, and cultured in vitro. HSCs were randomly assigned to the PBS control group and IL-9 stimulation group (stimulation with 20 ng/mL IL-9). HSCs were harvested 48 h and 72 h poststimulation, and the expression of α-smooth muscle actin (α-SMA), type I collagen (Col I) and type III collagen (Col III) was determined in HSCs using Western blotting. RESULTS Following stimulation with 20 ng/mL IL-9 for 48 h, the expression of α-SMA [(0.87 ± 0.02) vs. (0.69 ± 0.01); t = 17.39, P < 0.01], Col I [(0.74 ± 0.02) vs. (0.65 ± 0.01); t = 9.56, P < 0.01] and Col III [(0.94 ±0.04) vs. (0.75 ± 0.03); t = 6.15, P < 0.01] was significantly greater in HSCs in the IL-9 stimulation group than in the PBS control group. Following stimulation with 20 ng/mL IL-9 for 72 h, the expression of α-SMA was significantly greater in HSCs in the IL-9 stimulation group than in the PBS control group[(0.76 ± 0.02) vs. (0.58 ± 0.02); t = 12.52, P < 0.01]; however, there were no significant differences between the two groups in terms of Col I [(0.68 ± 0.02) vs. (0.66 ± 0.02); t = 1.15, P > 0.05] or Col III expression [(0.75 ± 0.01) vs. (0.72 ± 0.02); t = 2.22, P > 0.05]. CONCLUSIONS IL-9 promotes the activation of HSCs in mice infected with S. japonicum.

Abstract
As a natural prebiotic in human milk, 2'-fucosyllactose (2'-FL) is actively used in infant formula (IF). However, the 2'-FL influence on the improvement of gut microbiota and the regulation of the immune function remains unknown. In this study, human microbiota-associated (HMA) mice were used to demonstrate that feeding 2'-FL-containing IF was comparable to human milk at levels of immune cytokines (IL-2, IL-9, IL-10, and sIgA) and short-chain fatty acids (SCFAs, i.e., acetate and propionate). In addition, 2'-FL increased the abundance of Blautia and Olsenella and improved the anti-inflammatory cytokine IL-10 levels. The abundance of Blautia and Olsenella positively correlated with the IL-10 levels. 2'-FL also decreased the abundance of Enterorhabdus and Lachnospiraceae_UCG-006 and elevated SCFA levels, showing a negative correlation between these genera and SCFAs. Our findings revealed that feeding 2'-FL-containing IF drives the levels of cytokines and SCFAs toward human milk levels by shaping the beneficial gut microbiota profile.

Abstract
Objectives To determine the profile of cytokines in patients with severe COVID-19 who were enrolled in a trial of COVID-19 convalescent plasma (CCP). Methods Patients were randomized to receive standard treatment and 3 CCP units or standard treatment alone (CAPSID trial, ClinicalTrials.gov NCT04433910). The primary outcome was a dichotomous composite outcome (survival and no longer severe COVID-19 on day 21). Time to clinical improvement was a key secondary endpoint. The concentrations of 27 cytokines were measured (baseline, day 7). We analyzed the change and the correlation between serum cytokine levels over time in different subgroups and the prediction of outcome in receiver operating characteristics (ROC) analyses and in multivariate models. Results The majority of cytokines showed significant changes from baseline to day 7. Some were strongly correlated amongst each other (at baseline the cluster IL-1ß, IL-2, IL-6, IL-8, G-CSF, MIP-1α, the cluster PDGF-BB, RANTES or the cluster IL-4, IL-17, Eotaxin, bFGF, TNF-α). The correlation matrix substantially changed from baseline to day 7. The heatmaps of the absolute values of the correlation matrix indicated an association of CCP treatment and clinical outcome with the cytokine pattern. Low levels of IP-10, IFN-γ, MCP-1 and IL-1ß on day 0 were predictive of treatment success in a ROC analysis. In multivariate models, low levels of IL-1ß, IFN-γ and MCP-1 on day 0 were significantly associated with both treatment success and shorter time to clinical improvement. Low levels of IP-10, IL-1RA, IL-6, MCP-1 and IFN-γ on day 7 and high levels of IL-9, PDGF and RANTES on day 7 were predictive of treatment success in ROC analyses. Low levels of IP-10, MCP-1 and high levels of RANTES, on day 7 were associated with both treatment success and shorter time to clinical improvement in multivariate models. Conclusion This analysis demonstrates a considerable dynamic of cytokines over time, which is influenced by both treatment and clinical course of COVID-19. Levels of IL-1ß and MCP-1 at baseline and MCP-1, IP-10 and RANTES on day 7 were associated with a favorable outcome across several endpoints. These cytokines should be included in future trials for further evaluation as predictive factors.

Abstract
IL-9, produced mainly by specialized T cells, mast cells, and group 2 innate lymphoid cells, regulates immune responses, including anti-helminth and allergic responses. Polarization of naive CD4 T cells into IL-9-producing T cells (Th9s) is induced by IL-4 and TGF-β1 or IL-1β. In this article, we report that the transcription factor growth factor-independent 1 transcriptional repressor (GFI1) plays a negative role in mouse Th9 polarization. Moreover, the expression of GFI1 is controlled by liganded RARα, allowing GFI1 to mediate the negative effect of retinoic acid on IL-9 expression. The Gfi1 gene has multiple RARα binding sites in the promoter region for recruiting nuclear coactivator steroid receptor coactivator-3 and p300 for histone epigenetic modifications in a retinoic acid-dependent manner. Retinoic acid-induced GFI1 binds the Il9 gene and suppresses its expression. Thus, GFI1 is a novel negative regulator of Il9 gene expression. The negative GFI1 pathway for IL-9 regulation provides a potential control point for Th9 activity.

Abstract
Background The peritumoral stroma is a hallmark of pancreatic ductal adenocarcinoma (PDA) with implications for disease development, progression and therapy resistance. We systematically investigated immune features of the stroma in PDA patients to identify markers of clinical importance and potential therapeutic targets. Methods Tissue and blood samples of 51 PDA patients with clinical and follow-up information were included. Laser Capture Microdissection allowed us to analyze the stromal compartment in particular. Systematic immunohistochemistry, followed by software-based image analysis were conducted. Also, multiplex cytokine analyses (including 50 immune-related molecules) were performed. Functional analyses were performed using patient-derived 3D bioprints. Clinical information was used for survival analyses. Intercompartmental IL9 and IL18 gradients were assessed in matched samples of tumor epithelium, stroma, and serum of patients. Serum levels were compared to an age-matched healthy control group. Results Stromal IL9 and IL18 are significantly associated with patient survival. While IL9 is a prognostic favorable marker (p=0.041), IL18 associates with poor patient outcomes (p=0.030). IL9 correlates with an anti-tumoral cytokine network which connects regulation of T helper (Th) 9, Th1 and Th17 cells (all: p<0.05 and r>0.5). IL18 correlates with a Th1-type cytokine phenotype and stromal CXCL12 expression (all: p<0.05 and r>0.5). Further, IL18 associates with a higher level of exhausted T cells. Inhibition of IL18 results in diminished Th1- and Th2-type cytokines. Patients with high stromal IL9 expression have a tumor-to-stroma IL9 gradient directed towards the stroma (p=0.019). Low IL18 expression associates with a tumor-to-stroma IL18 gradient away from the stroma (p=0.007). PDA patients showed higher serum levels of IL9 than healthy controls while serum IL18 levels were significantly lower than in healthy individuals. The stromal immune cell composition is distinct from the tumor epithelium. Stromal density of FoxP3+ regulatory T cells showed a tendency towards improved patient survival (p=0.071). Conclusion An unexpected high expression of the cytokines IL9 and IL18 at different ends is of significance in the stroma of PDA and relates to opposing patient outcomes. Sub-compartmental cytokine analyses highlight the importance of a differentiated gradient assessment. The findings suggest stromal IL9 and/or IL18 as markers for patient stratification and as potential therapeutic targets. Future steps include investigating e. g. the role of local microbiota as both cytokines are also regulated by microbial compositions.

Abstract
The immunopathology associated with Leishmaniasis is a consequence of inflammation. Upon infection with Leishmania, the type of host-immune response is determinant for the clinical manifestations that can lead to either self-healing or chronic disease. Multiple pathways may determine disease severity. A comparison of systemic immune profiles in patients with cutaneous leishmaniasis caused by L. guyanensis and healthy individuals with the same socio-epidemiological characteristics coming from the same endemic areas as the patients is performed to identify particular immune profile and pathways associated with the progression of disease development. Twenty-seven plasma soluble circulating factors were evaluated between the groups by univariate and multivariate analysis. The following biomarkers pairs IL-17/IL-9 (ρ=0,829), IL-17/IL-12 (ρ=0,786), IL-6/IL-1ra (ρ=0,785), IL-6/IL-12 (ρ=0,780), IL-1β/G-CSF (ρ=0,758) and IL-17/MIP-1β (ρ=0,754) showed the highest correlation mean among the patient while only INF-γ/IL-4 (ρ=0.740), 17/MIP-1β (ρ=0,712) and IL-17/IL-9 (ρ=0,707) exhibited positive correlation among the control group. The cytokine IL-17 and IL1β presented the greater number of positive pair correlation among the patients. The linear combinations of biomarkers displayed IP-10, IL-2 and RANTES as the variables with the higher discriminatory activity in the patient group compared to PDGF, IL-1ra and eotaxin among the control subjects. IP-10, IL-2, IL-1β, RANTES and IL-17 seem to be predictive value of progression to the development of disease among the Lg-infected individuals.

Abstract
Objective Graves’ disease (GD) is an organ-specific autoimmune disease characterized by the production of thyroid-stimulating antibodies (TSAb). The newly discovered CD4+ T helper cells, Th9 and Th17 lymphocytes, have been confirmed to be closely associated with a variety of immune diseases. However, relationships with the onset and development of GD remain unclear. The purpose of this study was to investigate the roles of Th9 and Th17 in the pathogenesis and prognosis of GD. Patients We recruited 26 patients with newly diagnosed GD, 45 patients with GD in remission, and 20 healthy individuals. Measurements Thyroid function and autoantibodies were evaluated using chemiluminescence immunoassays. Th9 and Th17 cells were analyzed using flow cytometry. The expression of Foxo1, IRF-4, RORc, IL-9, and IL-17 mRNA was examined using real-time PCR, and IL-9 and IL-17 protein levels were measured using enzyme-linked immunosorbent assay. Results Th9, Th17, and characteristic cytokines IL-9 and IL-17 in the GD-untreated group were significantly higher than those in the control and remission groups. The above indexes significantly decreased in the remission group, with the levels in the TRAb− remission group being similar to those in the normal group, while in the TRAb+ remission group, levels were differentially increased. TRAb titer was positively correlated with the levels of Th9, Th17, and their functional cytokines. Conclusions Th9 and Th17 cells may be involved in the pathogenesis and disease outcome of GD, which could provide a new direction for developing immunotherapy for patients with GD.

Abstract
Viral myocarditis (VM) is an important cause of heart failure (HF) in children and adults. However, the molecular determinants involved in cardiac inflammation and cardiomyocyte necrosis remain poorly characterized, and cardioprotective molecules are currently missing. Here, we applied an in vivo method based on the functional selection (FunSel) of cardioprotective factors using AAV vectors for the unbiased identification of novel immunomodulatory molecules in a Coxsackievirus B3 (CVB3)-induced myocarditis mouse model. Two consecutive rounds of in vivo FunSel using an expression library of 60 cytokines were sufficient to identify five cardioprotective factors (IL9, IL3, IL4, IL13, IL15). The screening also revealed three cytokines (IL18, IL17b, and CCL11) that were counter-selected and likely to exert a detrimental effect. The pooled overexpression of the five most enriched cytokines using AAV9 vectors decreased inflammation and reduced cardiac dilatation, persisting at 1 month after treatment. Individual overexpression of IL9, the top ranking in our functional selection, markedly reduced cardiac inflammation and injury, concomitant with an increase of anti-inflammatory Th2-cells and a reduction of pro-inflammatory Th17- and Th22-cells at 14 days post-infection. AAV9-mediated FunSel cardiac screening identified IL9 and other four cytokines (IL3, IL4, IL13, and IL15) as cardioprotective factors in CVB3-induced VM in mice.

Abstract
Asthma is a chronic inflammatory lung disease with intermittent flares predominately mediated through memory T cells. Yet, the identity of long-term memory cells that mediate allergic recall responses is not well defined. In this report, using a mouse model of chronic allergen exposure followed by an allergen-free rest period, we characterized a subpopulation of CD4+ T cells that secreted IL-9 as an obligate effector cytokine. IL-9-secreting cells had a resident memory T cell phenotype, and blocking IL-9 during a recall challenge or deleting IL-9 from T cells significantly diminished airway inflammation and airway hyperreactivity. T cells secreted IL-9 in an allergen recall-specific manner, and secretion was amplified by IL-33. Using scRNA-seq and scATAC-seq, we defined the cellular identity of a distinct population of T cells with a proallergic cytokine pattern. Thus, in a recall model of allergic airway inflammation, IL-9 secretion from a multicytokine-producing CD4+ T cell population was required for an allergen recall response.

Abstract
INTRODUCTION Chronic rhinosinusitis (CRS) is the most common immunological ENT disease, which has several phenotypes. The heterogeneity of CRS is due to the peculiarities of their pathogenetic mechanisms - the system of cytokines plays the crucial significance. They are biologically active substances and present regulatory peptides that demonstrate an immunomodulatory and regulatory effects not only in the local level but the system level as well. OBJECTIVE To determine specific features of the cytokine profile in blood serum among patients with CRS without polyps (CRSwP). MATERIAL AND METHODS Serum cytokines (IL-1α, IL-1RA, IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12p40, IL-12p70, IL-13, IL-15, IL-17, IFN-α2, IFN-γ, GM-CSF) were defined in 75 patients: 32 patients with CRSwP were operated (main group) - 17 with cyst of maxillary sinus, 15 with edema of the maxillary sinuses. The control group - 43 patients were under surgery for a deviated nasal septum (septoplasty). The groups were comparable to gender and age. RESULTS The cytokines detection rate was different in all groups. IL-4 (detection rate 93.3-95.3%) and IFN-γ (79.1-86.7%) were measured nearly the all groups. IL-8 (73.3-76.5%) and IL-17 (76.5-80.0%) were often measured in the group with CRSwP; in contrast to the control group - these indicators were lower: 60.5% and 65.5%, respectively. IL-1α (82.4%) and IFN-α2 (76.5%) were often detected in CRS with cystic formations. IL-1β, IL-5, IL-7, IL-9, IL-15 were measured in all groups in less than 30% of patients; IL-2 and IL-6 - in the group of CRS with cystic formation; IL-10, IL-12p40, IL-13 in the group with edema of maxillary sinuses. In a quantitative comparison of the concentration of cytokines. Significant differences in concentration of cytokines between the groups were not obtained (p>0.05) in terms of quantity. CONCLUSION CRSwP with cystic formation is characterized by the development of T2 type immune response and a higher inflammation-related tissue damage.

Abstract
CD4 T cell effector subsets not only profoundly affect cancer progression, but recent evidence also underscores their critical contribution to the anticancer efficacy of immune checkpoint inhibitors. In 2012, the two seminal studies suggested the superior antimelanoma activity of TH9 cells over other T cell subsets upon adoptive T cell transfer. While these findings provided great impetus to investigate further the unique functions of TH9 cells and explore their relevance in cancer immunotherapy, the following questions still remain outstanding: are TH9 cell anticancer functions restricted to melanoma? What are the factors favouring TH9 cell effector functions? What is the contribution of TH9 cells to cancer immunotherapy treatments? Can TH9 cells be identified in humans and, if so, what is their clinical relevance? By reviewing the studies addressing these questions, we will discuss how TH9 cells could be therapeutically harnessed for cancer immunotherapy strategies.

Abstract
Psoriasis is a T cell mediated chronic inflammatory skin disease affecting about 2% of the population worldwide. Recently has established the central role of IL-23/Th17 immune axis in the pathogenesis of psoriasis and different subclasses of T cells including Th1 and Th17 cells are involved in initiation and amplification of the skin inflammation process, in addition, in cases of recurrent psoriasis, Th22 cells play the role of memory cells with the help of Th9 cells, which are also important in this process. The main goal was to evaluate the ratio of T cell profile and IL23/Th17 axis by evaluating IL17A, IL22, IL9 in peripheral blood of persons with moderate to severe plaque psoriasis. We have estimated the activation of IL-23/Th17 axis by evaluating the level of IL-17A, IL-22 and IL-9 in peripheral blood of patients with plaque psoriasis (n=18) with different severity of the disease (PASI from 10 to 40) comparing the results with data obtained from healthy persons (n=15). The expression of CD69 activation marker on T helper cells has been evaluated as well. The results were analyzed using FACScan flow cytometer (Becton Dickinson). The percentage of CD3 + T lymphocytes in the peripheral blood of patients with psoriasis was not significantly different compared to normal healthy volunteers, however, the level of expression of CD4 + T cells was reduced. We observed a dramatic increase in IL22 along with a decrease in the level of expression of IL-9 and IL-17, the expression of Th activation marker (CD69) was also decreased in comparison with the control group. The T cell profile and the IL-23/Th17 axis functional activity levels were significantly different from the literature data obtained about the inflammatory region (psoriatic lesions on the skin). IL-9 and IL-17 expression levels are decreased in peripheral blood Th cells, which may be explained by mobilization of the corresponding Th9 and Th17 cells into the inflammatory site.

Abstract
In this issue, Ma et al. (https://doi.org/10.1084/jem.20171576) show that removal of cholesterol from CD8 T cells during type 9 differentiation increases their IL-9 production, persistence in vivo, and cytolytic function against tumors by preventing SUMOylation of liver X receptors.

Abstract
OBJECTIVE To investigate the serum levels of interleukin-4 (IL-4), interleukin-9 (IL-9), and immunoglobulin E (IgE) in the patients infected with intestinal helminths, and study their relationship to the clinical symptoms or species of the helminths. METHODS This study was carried out in the Department of Paediatrics, Henan Provincial People's Hospital from January 2010 to July 2014. The blood samples were collected from 55 infected patients. Among the 55 cases, 18 cases (32.7%) were with ascaris infection, 8 cases (14.5%) of hookworm infection, 7 cases (12.7%) of whipworm infection, and 22 cases (40%) of pinworm infection. ELISA were used to measure the levels of IL-4, IL-9, and IgE in peripheral blood samples from the patients and 15 healthy volunteers. The relationship between the concentration of the cytokines and clinical symptoms or species of the parasites was analyzed. RESULTS The serum levels of IL-4, IL-9, and IgE in infection group were (157.42 ± 41) pg/ml, (59.9 ± 21.7) pg/ml, and (316.6 ± 129) IU/ml, respectively, which were higher than that of the healthy control[ IL-4 (39.01 ± .5) pg/ml, IL-9 (21.3 ± 12.5) pg/m, IgE (127.7 ± 57.6) IU/ml] (P > 0.01). After treatment by albendazole in the infection group, the level of IL-4, IL-9, and IgE decreased to (98.1 ± 41.7) pg/ml, (38.7 ± 14.1) pg/ml, and (253.1 ± 94.0) IU/ml, respectively, but still higher than that of the control (P < 0.05). IL-9 level in patients with upper gastrointestinal hemorrhage was (76.1 ± 23.5) pg/ml, which was higher than that of those with abdominal discomfort or disruption to bowel habits [(54.3 ± 22.1) g/ml] (P < 0.05), but lower than that of those with allergic dermatitis [(108.5 ± 33.4) pg/ml] (P < 0.05). No significant difference was found in the levels of IL-4 and IgE among the above three groups. The level of IL-9 in patients infected with pinworms was (120.3 ± 41.0) pg/ml, which was higher than that of ascaris infection group [(90.1 ± 29.7) pg/ml], hookworm infection group [(77.3 ± 18.3) pg/ml], and whipworm infection group [(62.5 ± 24.3) pg/ml] (P < 0.01). There was no significant difference in the serum level of IL-9 between ascaris infection group and hookworm infection group (P > 0.05), whereas the IL-9 level in ascaris infection group and hookworm infection group was higher than that of whipworm infection group [(62.5 ± 24.3) pg/ ml] (P < 0.01). There were no significant difference in the serum level of IL-4 and IgE among the patients infected with the species of different helminthes (P > 0.05). CONCLUSION The levels of IL-4, IgE, and IL-9 are considerably related with intestinal helminth infection, while IL-9 level varied with different helminth species and clinical symptoms.

Abstract
CD4(+) T-helper cells that selectively produce interleukin (IL)-17 (T(H)17), are critical for host defence and autoimmunity. Although crucial for T(H)17 cells in vivo, IL-23 has been thought to be incapable of driving initial differentiation. Rather, IL-6 and transforming growth factor (TGF)-β1 have been proposed to be the factors responsible for initiating specification. Here we show that T(H)17 differentiation can occur in the absence of TGF-β signalling. Neither IL-6 nor IL-23 alone efficiently generated T(H)17 cells; however, these cytokines in combination with IL-1β effectively induced IL-17 production in naive precursors, independently of TGF-β. Epigenetic modification of the Il17a, Il17f and Rorc promoters proceeded without TGF-β1, allowing the generation of cells that co-expressed RORγt (encoded by Rorc) and T-bet. T-bet(+)RORγt(+) T(H)17 cells are generated in vivo during experimental allergic encephalomyelitis, and adoptively transferred T(H)17 cells generated with IL-23 without TGF-β1 were pathogenic in this disease model. These data indicate an alternative mode for T(H)17 differentiation. Consistent with genetic data linking IL23R with autoimmunity, our findings re-emphasize the importance of IL-23 and therefore may have therapeutic implications.

Abstract
Mucosal mast cells (MMC) play an important role in the immune response against selected species of intestinal nematode. The kinetics with which different strains of inbred mice resolve infection with Trichinella spiralis correlates with their ability to mount MMC responses in the intestinal mucosa. Homologues of MMC that express and constitutively secrete abundant amounts of the granule chymase, mouse mast cell protease-1 (mMCP-1), can be generated in vitro from bone marrow cultures supplemented with interleukins-3 and -9, stem cell factor and transforming growth factor-beta1. Using the enhanced growth characteristics of these MMC homologues, a novel limiting dilution assay for mast cell precursor (MCp) frequency has been developed. The assay is highly specific, in that cultures containing mast cells are identified with mMCP-1 specific antibody, and almost three-fold more sensitive than previously published systems. MCp frequencies were compared in BALB/c and C57/BL10 strains of mice that, respectively, respond rapidly and slowly to infection with T. spiralis. MCp frequency (1/378 bone marrow cells) was significantly greater in BALB/c than C57/BL10 mice (frequency: 1/751). Similarly the rate of growth of MMC homologues and the production of mMCP-1 was significantly greater in BALB/c than in C57/BL10 bone marrow cultures.

Abstract
The 320-kb human pseudoautosomal region 2 (PAR2) at the tips of the long arms of the X and Y chromosomes is thought to have been duplicated onto the Y chromosome recently in primate evolution. The four genes within PAR2 have been proposed to constitute two zones with different base ratios and transcription, one of which was added recently to the X chromosome. To test this hypothesis, we cloned and mapped PAR2 genes in other species, the lemur, the cat, and a marsupial, the tammar wallaby. None of the human PAR2 genes colocalized with human PAR1 genes in the marsupial genome, confirming that the human PAR1 and PAR2 evolved independently. Of the four PAR2 genes, only SYBL1 was located on the X chromosome in all species, including marsupials, so it was part of the ancient X. HSPRY3 localized to the X in all the eutherians, but not marsupial, so it must have been added to the X 80-130 million years ago. CXYorf1 was present on the X in primates and also in mouse, but autosomal in wallaby, suggesting a later addition 70-130 million years ago, and IL9R was on the X only in primate, suggesting addition 60-70 million years ago. The results therefore demonstrate that at least two independent additions were necessary for PAR2 evolution. The present gene order on the human X also requires two inversions. The complicated evolutionary pathway supports the hypothesis that terminal interchromosomal rearrangements are common in regions unpaired at meiosis.

Abstract
The combination of immunotherapy with conventional treatments such as radio- and chemotherapy may be necessary to eradicate minimal residual disease. Interleukin 12 (IL-12) is a heterodimeric cytokine composed of two subunits, p40 and p35. Coordinate expression of the IL-12 p40 and p35 genes in several solid tumor models has been found to induce strong and specific antitumor immune responses. In the interest of obtaining high level IL-12 expression in leukemia/lymphoma cells for use as vaccines in cancer immunotherapy, we evaluated three IL-12 retroviral vector designs based on the murine stem cell virus (MSCV) vector which efficiently transduces functional genes into normal hematopoietic cells. MSCVpac-mlL-12 and MIPV-mIL-12 contain an encephalomyocarditis virus internal ribosome entry site for internal translation of bicistronic mRNA transcripts, while MDCVpac-mIL-12 carries an expression cassette in the U3 region of the 3' long terminal repeat. We found that the MSCVpac-mIL-12 vector directed robust expression of both p40 and p35 genes in several murine tumor cell lines of hematopoietic origin, including a T-cell lymphoma, a B-cell lymphoma, and a plasmacytoma/myeloma. In contrast, genomic instability or promoter interference hampered p40 gene expression in cells transduced with the MIPV-mIL-12 and MDCVpac-mIL-12 vectors, respectively. These findings provide the basis for the design of IL-12 retroviral vectors for the treatment of hematologic malignancies in humans.
