The aim of the study was to identify changes in concentrations of pro- and anti-inflammatory cytokines, depending on the severity of health disorders in workers. Under observation there were employees working in conditions of the occupational vibration (experienced workers with a long-term working period without signs of the disorders of health, patients with the vibration-induced disease (VID) and patients with VID at the remote period). There was established the aggravation of the imbalance of pro- and anti-inflammatory cytokines with an increase in the severity of the pathological process. There were identified unidirectional changes of indices in patients with various degree of the severity of the health disorder characterized by a decrease in serum concentrations of TNF-α, IFN-γ, IL-4, IL-10. This is apparently due to the inhibition of the functional activity as T helper type 1 and T helper type 2. The determination of mediators of the immune response in employees of vibration hazard occupations may serve as a marker for the early screening assessment of health problems and the severity of the clinical course of the VID.

The aim of the research is to study the content of some key pro / anti-inflammatory cytokines in patients with osteoarthritis and to evaluate their role in predicting atherogenesis in this category of patients. Material and methods. Patients with primary osteoarthritis of I-III radiological stages were examined. Doppler vessels ultrasound (Doppler ultrasound) of the neck, upper and lower extremities was performed; blood levels of pro / anti-inflammatory cytokines were examined: IL-1β, TNF-α, IL-6, IL- 8, IL-18, MCP-1, IL-17, IL-10, IL-33 by flow cytometry. Results. According to the thickness of intima - media complex, the patients were divided into 2 groups: with a normal thickness of intima - media complex and with atherosclerotic plaque. A significant increase in pro-inflammatory cytokines was revealed in patients with osteoarthritis associated with atherosclerosis compared with those having osteoarthritis with normal thickness of intima-media complex. The level of pro / anti-inflammatory cytokines along with atherosclerosis are closely interconnected. Conclusion. According to the results of the studies obtained, it was found that a long-term subclinical inflammatory process leads to multidirectional disturbances in cytokine balance in patients with osteoarthritis, which probably contributes to the progression of both osteoarthritis and atherosclerosis. A possible factor of early atherosclerosis development in patients with osteoarthritis was also identified.

Interleukin-10 (IL-10) is a cytokine derived fromCD4+T-helper type 2 (TH2) cells identified as a suppressor of cytokines from T-helper type 1(TH1) cells. Interleukin-12 (IL-12) is produced by B cells, macrophages and dendritic cells, and primarily regulates TH1cell differentiation, while suppressing the expansion of TH2cell clones. Interferon-γ (IFN-γ) is a product of TH1cells and exerts inhibitory effects on TH2cell differentiation. These cytokines have been implicated in the pathogenesis of asthma and allergies. In this context, IL-12 and IFN-γ production in asthma have been found to be decreased, and this may reduce their capacity to inhibit IgE synthesis and allergic inflammation. IL-10 is a potent inhibitor of monocyte/macrophage function, suppressing the production of many pro-inflammatory cytokines. A relative underproduction of IL-10 from alveolar macrophages of atopic asthmatics has been reported. Therapeutic modulation of TH1/TH2imbalance in asthma and allergy by mycobacterial vaccine, specific immunotherapy and cytoline-guanosine dinucleotide motif may lead to increases in IL-12 and IFN-γ production. Stimulation of IL-10 production by antigen-specific T-cells during immunotherapy may lead to anergy through inhibition of CD28-costimulatory molecule signalling by IL-10s anti-inflammatory effect on basophils, mast cells and eosinophils.

Introduction: Obesity is a disorder with low-grade chronic inflammation that plays a key role in the hepatic inflammation and steatosis. Moreover, there are studies to support the role of exosomes in the cellular communications, the regulation of metabolic homeostasis and immunomodulatory activity. Accordingly, we aimed to evaluate the influence of plasma circulating exosomes derived from females with normal-weight and obesity on the secretion of inflammatory cytokines in human liver cells. Methods: Plasma circulating exosomes were isolated from four normal (N-Exo) and four obese (O-Exo) women. The exosomes were characterized and approved for CD63 expression (common exosomal protein marker) and morphology/size using the western blot and TEM methods, respectively. The exosomes were used for stimulation of HepG2 cells in vitro. After 24 h incubation, the protein levels of TNF-α,IL-6, and IL-1β were measured in the culture supernatant of HepG2 cells using the ELISA kit. Results: The protein levels of IL-6 and TNF-α in the cells treated with O-Exo and N-Exo reduced significantly in comparison with control group (P=0.039 and P<0.001 respectively), while significance differences were not found between normal and obese groups (P=0.808, and P=0.978 respectively). However, no significant differences were found between three groups in term of IL-1β levels (P=0.069). Based on the correlation analysis, the protein levels of IL-6 were positively correlated with TNF-α (r 0.978, P<0.001). Conclusion: These findings suggest that plasma circulating exosomes have probably anti-inflammatory properties independently from body mass index and may decrease the secretion of inflammatory cytokines in liver. However, further investigations in vitro and in vivo are needed to address the anti-inflammatory function of N-Exo and O-Exo in human liver cells and/or other cells.

Abstract Background Muscle stem cells (MuSCs) are absolutely required for the formation, repair, and regeneration of skeletal muscle tissue. Increasing evidence demonstrated that tissue stem cells, especially mesenchymal stem cells (MSCs), can exert therapeutic effects on various degenerative and inflammatory disorders based on their immunoregulatory properties. Human mesenchymal stem cells (hMSCs) treated with interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) were reported to possess anti-inflammatory functions by producing TNF-stimulated gene 6 (TSG-6). However, whether human muscle stem cells (hMuSCs) also possess TSG-6 mediated anti-inflammatory functions has not been explored. Methods The ulcerative colitis mouse model was established by subjecting mice to dextran sulfate sodium (DSS) in drinking water for 7 days. hMuSCs were pretreated with IFN-γ and TNF-α for 48 h and were then transplanted intravenously at day 2 of DSS administration. Body weights were monitored daily. Indoleamine 2,3-dioxygenase (IDO) and TSG-6 in hMuSCs were knocked down with short hairpin RNA (shRNA) and small interfering RNA (siRNA), respectively. Colon tissues were collected for length measurement and histopathological examination. The serum level of IL-6 in mice was measured by enzyme-linked immunosorbent assay (ELISA). Real-time PCR and Western blot analysis were performed to evaluate gene expression. Results hMuSCs treated with inflammatory factors significantly ameliorated inflammatory bowel disease (IBD) symptoms. IDO and TSG-6 were greatly upregulated and required for the beneficial effects of hMuSCs on IBD. Mechanistically, the tryptophan metabolites, kynurenine (KYN) or kynurenic acid (KYNA) produced by IDO, augmented the expression of TSG-6 through activating their common receptor aryl hydrocarbon receptor (AHR). Conclusion Inflammatory cytokines-treated hMuSCs can alleviate DSS-induced colitis through IDO-mediated TSG-6 production.

The intervention with the Mediterranean diet (MD) pattern has evidenced short-term anti-inflammatory effects, but little is known about its long-term anti-inflammatory properties at molecular level. This study aims to investigate the 3-year effect of MD interventions compared to low-fat diet (LFD) on changes on inflammatory biomarkers related to atherosclerosis in a free-living population with a high-risk of cardiovascular disease (CD). Participants (n = 285) in the PREDIMED trial were randomly assigned into three intervention groups: MD with extra-virgin olive oil (EVOO) or MD-Nuts, and a LFD. Fourteen plasma inflammatory biomarkers were determined by Luminex assays. An additional pilot study of gene expression (GE) was determined by RT-PCR in 35 participants. After 3 years, both MDs showed a significant reduction in the plasma levels of IL-1β, IL-6, IL-8, TNF-α, IFN-γ, hs-CRP, MCP-1, MIP-1β, RANTES, and ENA78 (p < 0.05; all). The decreased levels of IL-1β, IL-6, IL-8, and TNF-α after MD significantly differed from those in the LFD (p < 0.05). No significant changes were observed at the gene level after MD interventions, however, the GE of CXCR2 and CXCR3 tended to increase in the control LFD group (p = 0.09). This study supports the implementation of MD as a healthy long-term dietary pattern in the prevention of CD in populations at high cardiovascular risk.

Background: Exercise-associated immune response plays a crucial role in the aging process. The aim of this study is to investigate the effect of sport intensity on cytokine levels, oxidative stress markers and telomere length in aging elite athletes. Methods: In this study, 80 blood samples from consenting elite athletes were collected for anti-doping analysis at an anti-doping laboratory in Italy (FMSI). Participants were divided into three groups according to their sport intensity: low-intensity skills and power sports (LI, n = 18); moderate-intensity mixed soccer players (MI, n = 31); and high-intensity endurance sports (HI, n = 31). Participants were also divided into two age groups: less than 25 (n = 45) and above 25 years old (n = 35). Serum levels of 10 pro and anti-inflammatory cytokines and two antioxidant enzymes were compared in age and sport intensity groups and telomere lengths were measured in their respective blood samples. Results: Tumor necrosis factor-alpha (TNF-α) was the only cytokine showing significantly higher concentration in older athletes, regardless of sport intensity. Interleukin (IL)-10 increased significantly in HI regardless of age group, whereas IL-6 concentration was higher in the older HI athletes. IL-8 showed a significant interaction with sport intensity in different age groups. Overall, significant positive correlations among levels of IL-6, IL-10, IL-8 and TNF-α were identified. The antioxidant catalase activity was positively correlated with levels of TNF-α. Telomere length increased significantly with sport intensity, especially in the younger group. Conclusion: HI had longer telomeres and higher levels of pro- and anti-inflammatory cytokines, suggesting less aging in HI compared to low and moderate counterparts in association with heightened immune response. Investigation of the functional significance of these associations on the health and performance of elite athletes is warranted.

The pineal gland produces the important hormone melatonin, the level of which in the blood of pregnant women decreases in case of placental insufficiency. The effect of dysfunction of the pineal gland on the immune system of pregnant women and on the angiogenic activity of the placenta during pregnancy remains insufficiently studied. Objective: to establish the effect of our method of non-drug correction of function of pineal gland on the state of the cytokine part of the immune system and on the synthesis of placental growth factor (PlGF) in pregnant women with placental insufficiency manifesting as fetal intrauterine growth restriction (IUGR). Material and methods. 46 pregnant women with IUGR at 30-36 weeks of gestation were examined. The group was divided into two subgroups: with non-drug correction of the pineal gland function (n = 25) and without correction (n = 21). The method of correction included a set of measures of following of lighting regimen, activity and sleep for 14 days. The control group consisted of 20 women with uncomplicated pregnancy. Levels of melatonin, PlGF, TNF-α, IL-1β, IL-6, IL-4, IL-10 were determined in the venous blood by enzyme-linked immunosorbent assay. Results. It was established that the concentration of melatonin in the blood of pregnant women with IUGR was significantly reduced, as well as the concentration of PlGF (p < 0.01). Significant changes were also found in pregnant women with placental insufficiency, namely, increased concentrations of proinflammatory cytokines, such as TNF-α (p < 0.05), IL-1-β (p < 0.001) and IL-6 (p < 0.05), comparing to healthy pregnant women. Also, in the group of pregnant women with IUGR the levels of anti-inflammatory cytokines IL-4 (p <0.001) and IL-10 (p < 0.001) were elevated in comparison to the control group. After application of the developed complex of non-drug correction of pineal gland function, the concentration of melatonin in the blood of pregnant women in the subgroup of correction increased significantly, comparing to the subgroup without correction (p < 0.001), as well as the level of PlGF (p < 0.05). Also, significantly lower levels of proinflammatory cytokines TNF-α, IL-1-β and IL-6 were observed in pregnant women in the subgroup of correction (p < 0.01). Regarding anti-inflammatory cytokines, under the influence of the developed complex of measures there was a decrease in the level of IL-4 and an increase in the level of IL-10 (p < 0.01). Conclusions. When the measures, aimed at non-drug correction of function of pineal gland, are applied in pregnant women with placental insufficiency, manifested as IUGR, the following changes are observed: increased of plasma levels of melatonin and placental growth factor, decreased of levels of proinflammatory cytokines. We suggest that the pineal gland exerts its effect on the immune system through melatonin, which moderates the activity of pro- and anti-inflammatory cytokines, thereby reducing the influence of inflammation on placental tissue, what results in increasing of concentrations of placental growth factor in the blood of pregnant women.

The advantage in response of Th2 over Th1 is observed in normal pregnancy in peripheral blood. A disturbance of this balance can lead to symptoms of miscarriage and pregnancy loss. The aim of this study was to evaluate the pro- and anti-inflammatory cytokines in sera of women who were diagnosed with missed miscarriage in the first trimester and to compare this systemic immune response to the response in women with normal pregnancy. The study group consisted of 61 patients diagnosed with missed miscarriage. In total, 19 healthy women with uncomplicated first trimester created the control group. Cytokines were determined in the maternal serum by ELISA. The analysis included INF-γ, TNF-α, Il-1β, Il-4, Il-5, Il-6, Il-9, Il-10, Il-13 and TGF-β1. Th1 cytokine levels in the study group reached slightly higher values for INF-γ, Il-1β and slightly lower for IL-6 and TNF-α. In turn, Th2 cytokine levels in the study group were slightly higher (Il-9, Il-13), significantly higher (Il4, p = 0.015; Il-5, p = 0.0003) or showed no differences with the control group (Il-10). Slightly lower concentration involved only TGF-β1. Analysis of the correlation between levels of pro- and anti-inflammatory cytokines resulted in some discrepancies, without showing predominance of a specific immune response. The results did not confirm that women with missed miscarriage had an advantage in any type of immune response in comparison to women with normal pregnancy.

Inflammation plays a key role in the initiation, progression, and clinical manifestation of atherosclerosis. Cigarette smoking is a risk factor for atherosclerosis and cardiovascular disease. The aim of the current study was to investigate the serum concentrations of 12 cytokines and growth factors (EGF, INF-γ, IL-1α/-1β/-2/-4/-6/-8/-10, MCP-1, TNF-α, and VEGF) in an Iranian population, including 192 smokers, comparing these values with concentrations in nonsmokers. One hundred and ninety-two cases were enrolled from the Mashhad University of Medical Sciences. Of these cases, 82 were cigarette smokers and 110 were nonsmokers. Sex and age were matched for the two groups. The serum concentration of 12 cytokines and growth factors were determined using EV-3513-cytokine-biochip arrays, by competitive chemiluminescence immunoassays. The level of serum MCP-1 was significantly ( p < .001) lower in the female group of cigarette smokers (mean = 88.1 dL/ng), compared with nonsmokers (mean = 155.6 dL/ng). There were no significant differences for the other cytokines and growth factors between the groups. Our finding demonstrate the association of MCP-1 with cigarette smoking, supporting further studies in larger population on evaluating the role of cigarette smoking on pro-/anti-inflammatory cytokines.
