A growing body of literature suggests that cytokines play an important part in the pathogenesis of chronic nasal sinusitis. However, the mechanism by which the expression of cytokines in chronic nasal sinusitis is upregulated has not been well documented. The present study investigated the role of nuclear factor-kappa B (NF-κB) activation in upregulating the expression of interleukin-5, -6 and -8 (IL-5, IL-6 and IL-8). We titrated the levels of IL-5, IL-6 and IL-8 in nasal mucosa in 52 cases of chronic nasal sinusitis and 12 normal subjects using enzyme-linked immunosorbent assay. According to whether allergic rhinitis was associated or not, we subdivided the patients into the AR group (with allergic rhinitis) and the NAR group (without allergic rhinitis). Semi-quantitative reverse transcription-polymerase chain reaction and immunohistochemical staining were used to evaluate expression and activation of NF-κB P50 and P65 subunits in nasal mucosa. The correlation between activities of P50 and P65 and cytokines expression was analysed. Our results showed that IL-5, IL-6 and IL-8 in both the AR and NAR groups were strikingly elevated in comparison with the control group (all p < 0.01 for AR group; p < 0.05, 0.05, 0.01, respectively, for NAR group); and they were even higher in the AR group than those in the NAR group (p < 0.01, 0.05, 0.01, respectively). P50 and P65 mRNA levels in both AR and NAR groups were markedly greater than those in the control group (all p < 0.01); and the AR group had further higher levels as compared with the NAR group (both p < 0.05). Immunohistochemical study revealed that nucleus-positive rates of P50 and P65 in both AR and NAR groups were significantly higher than those of the control group (all p < 0.01), and they were much greater in the AR group in comparison with the NAR group (all p < 0.01). Pearson correlation analysis demonstrated that P50 and P65 nucleus-positive rates were closely correlated with IL-6 and IL-8 levels, but not IL-5, with a correlation coefficient of 0.49 for P50 and IL-6, 0.54 for P50 and IL-8, 0.61 for P65 and IL-6, and 0.66 for P65 and IL-8 (all p < 0.01). In conclusion, upregulated expression and activation of NF-κB P50 and P65 might be one of the mechanisms for induction of IL-6 and IL-8 expression in chronic nasal sinusitis. Association of allergic rhinitis with chronic nasal sinusitis further enhanced NF-κB activity, and subsequently lead to even stronger expression of IL-6 and IL-8. IL-5 expression appeared to be independent of NF-κB pathway in chronic nasal sinusitis.

Asthma and periodontitis are both very prevalent worldwide. Although the association between these diseases has been investigated, the biological mechanism underlying this association, especially the role of biological mediators, remains unclear. Thus, the aim of this study was to evaluate serum levels of anti-Porphyromonas gingivalis IgG in subjects with and without severe asthma. A case-control study involving 169 individuals consisted of subjects with severe asthma in addition to others without asthma (control group). An indirect enzyme linked immunosorbent assay (ELISA) was performed to measure serum levels of IgG specific to Porphyromonas gingivalis. Bacterial DNA was extracted from subgingival biofilm samples and real-time polymerase chain reaction (RT-PCR) analysis was performed to quantify Porphyromonas gingivalis levels.

Purpose: Helicobacter pylori is recognized as one of the prevalent causes of human gastricinfection. In the present study, the role of mixed immunization with H. pylori lipopolysaccharide(LPS) and recombinant cytotoxin-associated gene A (rCagA) as a stimulator of host immuneresponses was determined. Methods: BALB/c mice were immunized with different formulations by the systemic administrationat 14-day intervals. The effects of the formulations plus CpG adjuvants were assessed before andpost-immunization in separated studies. Moreover, the expression of Th1/Th2 cytokines wasquantified in sera of immunized mice using reverse transcription polymerase chain reaction (RTPCR)test and the protein levels confirmed with enzyme linked immunosorbent assay (ELISA).Finally, the specific antibody levels in sera were studied by ELISA and the tendency of cellularresponse was examined by IgG1/IgG2a ratio. Results: Data of Western blotting verified the presence of constructed protein. Analysisof lymphocyte proliferation showed that CpG-conjugated rCagA increases lymphocytesproliferation compared to the control group. Also, it was shown that formulations containing LPSand rCagA promote a Th1 response indicated by interferon-gamma expression and induced Th1/Th2 balance. Additionally, the specific IgG1, total IgG and IgG2a levels elevated in response toall treatments. Ultimately, the IgG2a/IgG1 ratio in the mice immunized with rCagA-containingformulations increased. Conclusion: These results indicated that rCagA protein carried with CpG adjuvant not onlymaintained its antigenicity throughout the experiment but also induced robust Th1-biasedimmune responses. Therefore, it holds promise for the production of an efficient vaccine againstH. pylori infection. <br />

Abstract Expression of proinflammatory cytokines, such as interleukin (IL)-6 (IL-6) and metalloproteases, are elevated in patients with rotator cuff tear (RCT). In order to investigate the role of IL-6 gene polymorphisms on RCT risk, we genotyped two SNPs on IL-6 gene (rs1800795 and rs1800797) in 138 RCT patients and 137 healthy controls using polymerase chain reaction (PCR) and Sanger sequencing. The IL-6 expression in shoulder joint synovial fluid was determined by using enzyme-linked immunosorbent assay (ELISA) method. The constant score and visual analog scale (VAS) were used to evaluate the clinical outcome of two s (surgicsal vs. conservative) for RCT patients. For rs1800795, individuals with the GG genotype or G allele had significantly higher risk of RCT. Elevated risk of tear size was associated with the GG genotype of the rs1800795 polymorphism. The IL-6 rs1800797 polymorphism was also associated with an increased risk of RCT, especially among female, drinkers, and individuals with B(MI) &lt; 25 kg/m2. The elevated levels of IL-6 gene were observed among the mutant genotype of rs1800795/rs1800797 polymorphism. Surgical group is significantly better than conservative treatment from the perspective of constant score and VAS. Furthermore, CG genotype of rs1800795 polymorphism increased the constant score at 6 months in comparison with CC genotype. In conclusion, our study supports a role of IL-6 rs1800795/rs1800797 polymorphisms on increased RCT risk. The RCT patients with CG genotype of rs1800795 polymorphism have more obvious surgical treatment effects by influencing the IL-6 expression.

Background: Allergic rhinitis (AR) is one of the most common diseases in the world and affects about 10-50% of the general population. Probiotics are live microorganisms that help the normal state of the intestine, and if prescribed correctly, they can stimulate the mucosal immune system to prevent inflammatory symptoms of allergy and atopy. The present study aims to investigate the role of probiotics in the treatment of AR when added to standard therapy as adjuvant agents. Materials and Methods: In this clinical trial study, 28 patients older than 15 years with AR randomly divided into probiotics and control groups. The probiotics group received standard therapy for AR accompanied by probiotic capsules every 12 hours for eight weeks, whereas the control group received standard therapy for AR with placebo capsules as the same protocol. Data were analyzed using SPSS Version 23 (IBM Corporation, Armonk, NY, USA) and, the P-value less than 0.05 was considered statistically significant. Results: In the probiotics group, 14.3% of patients had sneezing at the baseline, which significantly decreased to 4.6% (P<0.01). Also, the necessity for nasal and oral corticosteroids after treatment with probiotics in the probiotics group was less than the control group (P<0.01). Although cough, nasal discharge, conchae hypertrophy, and night sleep disorders reduced after treatment with probiotics, this reduction was not statistically significant between the two groups. Conclusion: Based on the results of this clinical trial, the use of probiotics had no significant effect on the outcome of patients with AR. [GMJ.2020;9:e1918]

Colorectal cancer (CRC) is classified as one of the most prevalent cancer types worldwide, with high morbidity and mortality rates. Patients of CRC have been shown to express a detectable cytokine in serum which contributes to cancer pathogenesis. Therefore, the serum interleukin 10 (IL-10) level in CRC patients was investigated in this study. Patients' medical records with CRC admitted to the Rizgary and Nanakali hospitals, Erbil, Iraq was analyzed as the study group compared to the healthy volunteers' control group. Seventy-one serum samples were collected, thirty-one from diagnosed CRC patients and forty from healthy controls. The concentrations of IL-10 in the sera were assessed by enzyme-linked immunosorbent assay (ELISA). The present finding showed that IL-10 Was significantly elevated in CRC patients' sera compared to the control group, suggesting confirmation of its usefulness for detecting CRC patients' prognosis. A non-significant Pearson correlation was detected between IL-10 serum levels and the CRC group's age, gender, and body mass index. Herein is the first study on the evaluation of IL-10 levels in CRC patients in Kurdistan, Iraq.

Objectives. Interleukin-27 (IL-27) has been reported to inhibit type 2 T helper cell (Th2) response in allergic rhinitis (AR). However, its effects on group II innate lymphoid cells (ILC2) in AR are not fully understood. Methods. Nineteen patients with AR and nineteen controls were enrolled in this study. The effects of IL-27 on ILC2 differentiation and function as well as the regulation of the IL-27 receptor (IL-27R) were analyzed by tritiated thymidine incorporation, enzyme-linked immunosorbent assay (ELISA), and real-time polymerase chain reaction (PCR), respectively. AR mice were used to confirm the role of IL-27 in vivo. Results. The serum IL-27 protein expression in AR patients was significantly lower compared with controls. IL-27 decreased the ILC2 proliferation and type II cytokine secretion through the interaction with IL-27R. IL-27 also inhibited systemic and nasal ILC2 response of AR mice. Conclusion. IL-27 inhibited the proliferation and function of ILC2 in AR, implying that IL-27 may be used as new treatment target in AR.

This study explored the role of γ-aminobutyric acid transaminase (GABA-T) in the puberty and reproductive performance of female rats. Immunofluorescence technique, quantitative real-time PCR (RT-qPCR) and enzyme-linked immunosorbent assay (ELISA) were used to detect the distribution of GABA-T and the expression of genes and hormones in female rats, respectively. The results showed that GABA-T was mainly distributed in the arcuate nucleus (ARC), paraventricular nucleus (PVN) and periventricular nucleus (PeN) of the hypothalamus, and in the adenohypophysis, ovarian granulosa cells and oocytes. Abat mRNA level at 28 d was lowest in the hypothalamus and the pituitary; at puberty, it was lowest in the ovary. Abat mRNA level was highest in adults in the hypothalamus; at infancy and puberty, it was highest in the pituitary; and at 21 d it was highest in the ovary. After vigabatrin (GABA-T irreversible inhibitor) was added to hypothalamus cells, the levels of Abat mRNA and Rfrp-3 mRNA were significantly reduced, but Gnrh mRNA increased at the dose of 25 and 50 μg/mL; Kiss1 mRNA was significantly increased but Gabbr1 mRNA was reduced at the 50 μg/mL dose. In prepubertal rats injected with vigabatrin, puberty onset was delayed. Abat mRNA, Kiss1 mRNA and Gnrh mRNA levels were significantly reduced, but Rfrp-3 mRNA level increased in the hypothalamus. Vigabatrin reduced the concentrations of GABA-T, luteinizing hormone (LH) and progesterone (P4), and the ovarian index. Lactation performance was reduced in adult rats with vigabatrin treatment. Four hours after vigabatrin injection, the concentrations of GABA-T and LH were significantly reduced in adult and 25 d rats, but follicle-stimulating hormone (FSH) increased in 25 d rats. In conclusion, GABA-T affects the reproductive function of female rats by regulating the levels of Gnrh, Kiss1 and Rfrp-3 in the hypothalamus as well as the concentrations of LH and P4.

Abstract Honeysuckle has antiviral, antioxidative and anti-inflammatory properties. Allergic rhinitis (AR) is induced by immunoglobulin E (IgE)-mediated inflammatory reaction. Our study investigates whether honeysuckle extract (HE) has therapeutic effect on AR. An AR model of mice was established by ovalbumin (OVA). Hematoxylin–Eosin staining was used to assess nasal mucosa damage. Enzyme-linked immunosorbent assay (ELISA) was performed to determine serum histamine, IgE and interleukin (IL)-2, IL-4, IL-17 and interferon-γ (IFN-γ) from nasal lavage fluid. Western blot was carried out to analyze the protein level from nasal mucosa tissue. We found that HE not only decreased nasal rubbing and sneezing in AR mice, but also reduced AR-induced damage to nasal mucosa. Moreover, HE lowered the levels of serum IgE and histamine and inhibited IL-4 and IL-17 levels from AR mice but raised IL-2 and IFN-γ levels in AR-induced nasal lavage fluid. Our results also showed that HE elevated the protein levels of forkhead box P3 (Foxp3) and T-box transcription factor (T-bet) in AR-induced nasal mucosa tissue, whereas it inhibited signal transducer and activator of transcription (STAT) 3 and GATA binding protein 3 (GATA-3) protein levels. By regulating AR-induced inflammatory reaction and autoimmune response, HE also relieved OVA-induced AR. Thus, HE could be used as a potential drug to treat AR.

Objective. The present study aimed to identify changes in decidual natural killer (dNK) cells and related cytokines in women who have undergone induced abortions (IAs). The effects of dNK cells on subsequent pregnancies remain unknown. Accordingly, we sought to investigate whether a history of early pregnancy can change dNK cells and facilitate their role in the regulation of angiogenesis and trophoblast invasion. Materials and Methods. dNK cells were obtained from primiparous women who had undergone IA(s) prior to this study and primiparous women who had never been pregnant before this IA (control). Real-time polymerase chain reaction (PCR) was used to measure the mRNA levels of IFN-γ, IP-10, VEGF, and PLGF in dNK cells. The levels of these cytokines were quantified using the enzyme-linked immunosorbent assay. HUVEC and HTR-8/SVneo cells were used to evaluate the angiogenesis, migration, and invasion activities influenced by dNK cells. Results. In dNK cells, the mRNA level of IFN-γ was higher in the control group than that in the IA group. The secretion of IP-10 and VEGF was higher in the IA group compared to the control group. After coculturing with the dNK supernatant, the HTR-8/SVneo cells exhibited better invasiveness and migration in the IA group than those in the control group. Angiogenesis assay demonstrated that dNK cells from IA group might help HUVEC attain better tube formation ability. Conclusion. The findings of this study suggest that a history of early pregnancy has an impact on dNK cells. These trained dNK cells can regulate angiogenesis and trophoblast invasion and migration by promoting the production of certain cytokines.
