Abstract
PURPOSE OF REVIEW Chronic rhinosinusitis (CRS) is a complicated, heterogeneous disease likely caused by inflammatory and infectious factors. There is clear evidence that innate immune cells, including neutrophils and eosinophils, play a significant role in CRS. Multiple immune cells, including neutrophils and eosinophils, have been shown to release chromatin and granular proteins into the extracellular space in response to triggering extracellular traps (ETs). The formation of ETs remains controversial due to their critical function during pathogen clearance while being associated with harmful inflammatory illnesses. This article summarizes recent research on neutrophil extracellular traps (NETs) and eosinophil extracellular traps (EETs) and their possible significance in the pathophysiology of CRS. RECENT FINDINGS A novel type of programmed cell death called ETosis, which releases ETs, has been proposed by recent study. Significantly more NETs are presented in nasal polyps, and its granule proteins LL-37 induce NETs production in CRS with nasal polyps (CRSwNP) patients. Similar to NETs, developed in the tissue of nasal polyps, primarily in subepithelial regions with epithelial barrier defects, and are associated with linked to elevated tissue levels of IL-5 and S. aureus colonization. This article provides a comprehensive overview of NETs and EETs, as well as an in-depth understanding of the functions of these ETs in CRS.

Abstract
Objectives Allergic rhinitis (AR) refers to a form of respiratory inflammation that mainly affects the sinonasal mucosa. The purpose of this study was to explore the level of immune cell infiltration and the pathogenesis of AR. Methods We performed a comprehensive analysis of two gene expression profiles (GSE50223 and GSE50101, a total of 30 patients with AR and 31 healthy controls). CIBERSORT was used to evaluate the immune cell infiltration levels. Weighted gene coexpression network analysis was applied to explore potential genes or gene modules related to immune status, and enrichment analyses including gene ontology, Kyoto Encyclopedia of Genes and Genomes, gene set enrichment analysis, and gene set variation analysis, were performed to analyze the potential mechanisms in AR. A protein-protein interaction network was constructed to investigate the hub genes, and consensus clustering was conducted to identify the molecular subtypes of AR. Results Compared to the healthy controls, patients with AR had high abundance levels and proportions of CD4+ memory-activated T cells. One hundred and eight immune-related differentially expressed genes were identified. Enrichment analysis suggested that AR was mainly related to leukocyte cell-cell adhesion, cytokine-cytokine receptor interaction, T-cell activation, and T-cell receptor signaling pathway. Ten hub genes, including TYROBP, CSF1R, TLR8, FCER1G, SPI1, ITGAM, CYBB, FCGR2A, CCR1, and HCK, which were related to immune response, might be crucial to the pathogenesis of AR. Three molecular subtypes with significantly different immune statuses were identified. Conclusion This study improves our understanding of the molecular mechanisms in AR via comprehensive strategies and provides potential diagnostic biomarkers and therapeutic targets of AR.

Abstract
BACKGROUND Allergic rhinitis (AR) has been identified as a cause of olfactory dysfunction. Beyond the classic symptoms, AR has been associated with altered sleep patterns, a decline in cognitive performance and higher likelihood of depression and anxiety. The olfactory pathway has been postulated to be a possible link between nasal inflammation and central nervous system (CNS) modifications. Thus, we aimed to investigate the structural, functional and behavioral changes in the olfactory pathway and related areas in an animal model of AR. METHODS AR was induced in adult Wistar rats by ovalbumin sensitization and challenge. Following olfactory and behavioral tests we investigated the synaptic structure of the olfactory bulb (OB), anterior olfactory nuclei (AON), piriform cortex and prefrontal cortex (PFC), by immunofluorescence detection of synaptophysin (Syn) and glutamatergic, GABAergic and dopaminergic neuronal markers. RESULTS We detected a significant decrease in Syn in the glomerular layer (GL) of OB and in the PFC of the AR group. Additionally, the optical density of GAD67 and VGLUT2 was reduced in the OB, AON and PFC, compared to controls. The behavioral tests demonstrated olfactory dysfunction and reduced male aggressiveness in AR rats, but we did not find any difference in the cognition and anxiety-like behavior. CONCLUSIONS We confirmed olfactory dysfunction in a rat model of AR and we identified modifications in synaptic activity by reduction of Syn optical density in the GL of the OB and in the PFC. This was accompanied by structural changes in glutamatergic and GABAergic activity in essential components of the olfactory pathway and PFC.

Effect of experimental exposures to 3-D printer emissions on nasal allergen responses and lung diffusing capacity for inhaled carbon monoxide/nitric oxide in subjects with seasonal allergic rhinitis. INDOOR AIR 2022; 32:e13174. [PMID: 36437663 DOI: 10.1111/ina.13174] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/16/2022] [Revised: 11/02/2022] [Accepted: 11/03/2022] [Indexed: 06/16/2023]
Abstract
3-D printers are widely used. Based on previous findings, we hypothesized that their emissions could enhance allergen responsiveness and reduce lung diffusing capacity. Using a cross-over design, 28 young subjects with seasonal allergic rhinitis were exposed to 3-D printer emissions, either from polylactic acid (PLA) or from acrylonitrile butadiene styrene copolymer (ABS), for 2 h each. Ninety minutes later, nasal allergen challenges were performed, with secretions sampled after 1.5 h. Besides nasal functional and inflammatory responses, assessments included diffusing capacity. There was also an inclusion day without exposure. The exposures elicited slight reductions in lung diffusing capacity for inhaled nitric oxide (DLNO ) that were similar for PLA and ABS. Rhinomanometry showed the same allergen responses after both exposures. In nasal secretions, concentrations of interleukin 6 and tumor necrosis factor were slightly reduced after ABS exposure versus inclusion day, while that of interleukin 5 was slightly increased after PLA exposure versus inclusion.

Abstract
Objective To evaluate cytokine profile, vitamin D status, symptom score and quality of life in patients with persistent allergic airway diseases sensitised to house dust mites (HDM) in comparison with healthy individuals. Material and methods Patients sensitized to HDM with persistent AR and having symptoms for at least 2 years with or without AA were involved into the study. Measurements of vitamin D level in serum and IL-10, IL-13, IL-17, IL-22, IL-33 and IFN-gamma in serum and nasal lavage were performed by ELISA. Results Eighty-one subjects were involved into the study. Serum IL-10 concentration was higher in patients with AR than in patients with AR and AA (6.71 ± 1.73 vs. 1.98 ± 0.24, p < 0.05). IFN-gamma level in nasal lavage was higher in patients with AR and AA than in patients with AR (p < 0.01) and healthy individuals (p < 0.05) (7.50 ± 0.37 vs. 6.80 ± 0.99 vs. 6.50 ± 0.22). Serum IL-22 negatively correlated with IL-22 in nasal lavage, whereas serum IFN-gamma positively correlated with IFN-gamma in nasal lavage. Positive correlation between serum IL-17 and total IgE and negative correlation between IL-17 in nasal lavage and eosinophils in nasal smear were found in patients with AR and AA. Serum IFN-gamma decreased the risk of AR for healthy individuals. Serum IL-10 and vitamin D decreased risk for development of AA for patients with AR. IL-22 in serum and IL-10 and IL-33 in nasal lavage increased this risk. Conclusion Novel cytokines such as IL-22, IL-17 and IL-33 and vitamin D may be involved in pathogenesis of persistent airway inflammation in patients sensitized to HDM.

Abstract
Allergic rhinitis (AR) is a common upper airway disease attributed to a variety of risk factors, such as environmental exposures and genetic susceptibility. The commonly observed comorbidity of asthma and AR in the clinic suggests the presence of shared genetic risk factors and biological mechanisms between these diseases. Interleukin (IL)-33 has been indicated to be an important factor driving asthma susceptibility and pathogenesis using both genome-wide association studies and functional studies in model animals. Although previous studies have reported the putative association of this gene with AR, evidence for the association of genetic variations of IL-33 with the disease is still missing. To examine whether variations in the IL-33 gene confer a genetic risk of AR, a total of 769 patients with AR and 769 age- and sex-matched healthy controls were recruited among Han Chinese residents in the Hubei province, and 14 single-nucleotide polymorphisms (SNPs) spanning the IL-33 gene were examined for their association with the risk of AR. The results indicated that five SNPs, which were in a moderate linkage disequilibrium and were located in the 5'-flanking region of IL-33, exhibited significant associations with the risk of AR, and these associations were additionally supported by genotypic and haplotypic analyses. Notably, three of the five IL-33 SNPs have been previously reported to exhibit genome-wide associations with asthma, and their alleles were also revealed to confer an increased risk of AR in the present study. In summary, the results of the current study suggested that certain variations in the IL-33 gene represent a potential risk for AR, and indicated a shared genetic basis between AR and asthma.

Abstract
Background The aim was to determine the level of inflammatory cytokines, eosinophil cationic protein and IgE in allergic rhinitis (AR) patients. Subjects and methods Blood samples were taken from 88 AR patients and 88 healthy controls (HC). Each sample was analysed for eosinophil counts by flow cytometry, IgE by ECLIA, ECP, IL-17, and IL-33 by using ELISA test. Results There was no significant difference between AR patients and the control group in age and gender. Levels of eosinophils, IgE, ECP, IL-17, IL-33 and the total symptom scores were significantly higher in AR patients than the HC (P = 0.0001). Serum ECP correlated with IL-17 (P = 0.041, r = 0.42), IL-33 (P = 0.0001, r = 080), and IgE levels (P = 0.017, r = 0.45) in the R patients. There was no correlation between IL-17 and IL-33. There was a correlation between symptom scores and eosinophils (P = 0.026, r = 0.52), and IgE (P = 0.001, r = 0.60) in the patients. No correlation was observed between symptom scores and ECP, IL-17, and IL-33 in the AR patient. Conclusions Patients with AR have significant higher serum levels of ECP, IL-17, and IL-33 than healthy controls. This indicates that these markers could be used to in order to diagnose AR and to monitor disease. Inhibitory molecules to IL-17 and IL-33 may be considered as novel treatment strategies.

Abstract
Nasal secretions (NS) reflect inflammatory activity of the nasal mucosa and thus can be utilized for disease diagnosis and determining treatment effects in Allergic rhinitis (AR). However, non-standardized collection of samples can affect the measured concentration of inflammatory biomarker in NS. In this study, we aimed to develop and evaluate new devices capable of standardizing the collection, storage, and preprocessing methods of NS samples. First, we chose the best swab as polyester (PE) and selected a stimulation method, twirling for 10 s at 1 Hz, to efficiently release AR biomarkers from a PE swab. Storage of sample solutions at -20 °C was optimal for the stability of biomarkers for the detection of AR. The new swab sample transfer device showed excellent concentration recovery efficiency (90-100%) for tryptase (Trp) and eosinophil cationic protein (ECP) without crosstalk between the two biomarkers. Finally, we compared the concentration of Trp in human NS samples of AR patients (n = 6) pre-processed by the new device with that by centrifuge as a standard method. As a result, the concentrations of Trp in NS were very similar in both groups. Therefore, this device can be utilized as an effective sample transfer and pre-processing device for point-of-care testing of AR.

Abstract
BACKGROUND Bronchial asthma (BA) is a common chronic respiratory disease that has exhibited a rising global incidence in recent years. Glucocorticoids are used for the treatment of BA. Emerging evidence has demonstrated the roles of tumor necrosis factor (TNF-α), interleukin-8 (IL-8) and eosinophil cationic protein (ECP) in BA. The present study investigated whether TNF-α, IL-8 and ECP were associated with the clinical stages and severity of BA and the efficacy of glucocorticoids in the treatment of BA. METHODS A total of 199 patients with BA and 174 healthy individuals were included in this study. Patients with BA underwent glucocorticoid treatment, and the TNF-α, IL-8 and ECP levels and lung functions of the subjects were measured. The correlations of the TNF-α, IL-8 and ECP levels with BA severity, clinical staging and lung functions were assessed. We investigated whether the TNF-α, IL-8 and ECP levels aided in evaluating the efficacy of using glucocorticoids for the treatment of BA. RESULTS TNF-α, IL-8 and ECP exhibited high levels in patients with BA, and glucocorticoid treatment notably decreased these levels. The TNF-α, IL-8 and ECP levels were positively correlated with the clinical stages and severity of BA and negatively correlated with lung function. TNF-α, IL-8 and ECP can be used as serum markers to predict the efficacy of glucocorticoids in the treatment of BA. CONCLUSION The key findings of this study collectively support a role for TNF-α, IL-8 and ECP in BA development, and TNF-α, IL-8 and ECP can be used as serum markers of glucocorticoid efficacy in BA.

[PMID: 27275740 PMCID: PMC4898827 DOI: 10.1371/journal.pone.0157186] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2015] [Accepted: 05/25/2016] [Indexed: 12/27/2022] Open
Abstract
IL-5-induced chemotaxis of eosinophils is an important feature of allergic airway inflammatory diseases. Simvastatin, a lipid lowering agent, has been shown to exhibit anti-inflammatory and anti-allergic effects. Our aim was to investigate the effect of simvastatin on IL-5-induced eosinophil chemotaxis and its regulatory mechanisms. Eosinophils were derived by treating HL-60 clone 15 (HC15) cells with butyric acid (BA) in an alkaline condition or through direct isolation from human peripheral blood. The expressions of CC chemokine receptor 3 (CCR3) and interleukin (IL)-5 receptors (IL5Rα and β) were analyzed using RT/real-time PCR. The granular proteins were stained using fast green. Eotaxin-induced chemotaxis was measured using a transwell migration assay. CCR3 protein expression was revealed by immunocytochemistry. An animal model of allergic rhinitis was established by challenging Sprague-Dawley® rats repeatedly with ovalbumin. Butyric acid significantly increased the expression of IL5Rα and IL5Rβ, CCR3 and granular proteins in HC15 cells, indicating the maturation of eosinophils (BA-E cells). IL-5 further enhanced the CCR3 expression at both the mRNA and protein levels and the eotaxin-induced chemotaxis of BA-E cells. Simvastatin inhibited the effects of IL-5 on BA-E cells, but not in the presence of mevalonate. Similar results were also exhibited in human primary eosinophils. In vivo animal studies further confirmed that oral simvastatin could significantly suppress the infiltration of eosinophils into turbinate tissues of allergic rats. Therefore, simvastatin was demonstrated to inhibit IL-5-induced CCR3 expression and chemotaxis of eosinophils mediated via the mevalonate pathway. We confirmed that simvastatin also reduced eosinophilic infiltration in allergic rhinitis.

ALLERGY, ASTHMA & IMMUNOLOGY RESEARCH 2016; 8:329-37. [PMID: 27126726 PMCID: PMC4853510 DOI: 10.4168/aair.2016.8.4.329] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/16/2015] [Revised: 01/28/2016] [Accepted: 02/02/2016] [Indexed: 12/14/2022]
Abstract
Purpose Allergic rhinitis (AR) is a common and increasing disease in which Dermatophagoides (D.) farinae is one of the most common causative allergens. The aims of this study were to confirm the presence of locally produced antibodies to D. farinae in nasal secretions between nasal provocation test (NPT)-positive and -negative groups of AR patients, to evaluate their relationships with the levels of inflammatory mediators, and to determine adaptive and innate immune responses in nasal mucosa. Methods Sixty AR patients sensitive to house dust mites confirmed by skin prick test or serum specific IgE to D. farinae underwent NPT for D. farinae. Nasal packs were placed in both nasal cavities of the patients for 5 minutes to obtain nasal secretions after NPT. The levels of total IgE, specific IgE to D. farinae, eosinophil cationic protein (ECP), and tryptase in nasal secretions were detected by using ImmunoCAP. The levels of specific IgE, IgA, and secretory IgA antibodies to D. farinae in nasal secretions were measured by using ELISA. The levels of IL-8, VEGF, IL-25, and IL-33 were also measured by using ELISA. Results High levels of total IgE, specific IgE, specific IgA, and secretory IgA to D. farinae, as well as inflammatory mediators, such as ECP, IL-8, VEGF and tryptase, were detected in nasal secretions, although the differences were not statistically significant between the NPT-positive and NPT-negative groups. Levels of all immunoglobulins measured in this study significantly correlated with ECP, IL-8, and VEGF (P<0.05), but not with tryptase (P>0.05). IL-33 and IL-25 were also detected, and IL-25 level significantly correlated with IL-8 (r=0.625, P<0.001). Conclusions These findings confirmed the presence of locally produced specific antibodies, including D. farinae-specific IgE and IgA, in nasal secretions collected from D. farinae-sensitive AR patients in both the NPT-positive and NPT-negative groups, and close correlations were noted between antibodies and nasal inflammatory mediators, including such as ECP, IL-8 and VEGF, indicating that locally produced antibodies may be involved in the nasal inflammation of AR.

Abstract
BACKGROUND AND OBJECTIVES Chronic rhinosinusitis (CRS) is a commonly diagnosed disease that has a significant impact on a child's quality of life. However, no useful biomarker is available to identify antibiotic-responsive CRS. We determined the significance of eosinophil-related markers and total IgE levels in childhood CRS with regard to antibiotic response. DESIGN AND SETTING This was a case-control study of patients admitted to Uijeongbu St. Mary's Hospital between November 2010 and November 2011 and diagnosed with CRS. PATIENTS AND METHODS In this analytical cross-sectional study, we identified children whose symptoms and radiologic abnormalities did not resolve after 12 weeks despite appropriate antibiotics (non-responder CRS group), children whose symptoms and radiologic abnormalities resolved after 12 weeks with appropriate antibiotics (responder CRS group), and healthy controls selected from clinic patients. Skin prick tests were performed along with serum total IgE, total eosinophil count (TEC), serum eosinophil cationic protein (ECP) level, and ImmunoCAP analysis for common allergens. RESULTS This study included 36 responders, 22 nonresponders and 22 healthy controls. The prevalence of allergic diseases, atopy, and a family history of allergic diseases were significantly higher in the non-responder group than in the responder and control groups. TEC, ECP, and total IgE levels were significantly higher in the non-responder group than in the responder and control groups (all P < .05). Multiple linear regression analysis showed that no response to appropriate antibiotics and TEC was positively associated with ECP concentration. CONCLUSION These findings suggest that there is a high prevalence of allergic diseases in the non-responder group, that the TEC and ECP levels in the non-responder group are significantly higher than those in the responder group and controls, and that no response to antibiotics may be due to eosinophilic inflammation. The measurement of serum ECP may be useful in monitoring the progress of childhood CRS with regard to antibiotic response.

Abstract
Asthma and rhinitis are inflammatory diseases of the respiratory tract. Respiratory inflammation of the adaptive and innate immune system is the focus of this review, and chronic inflammation is not limited to the respiratory tissue. The inflammatory response, which consists of phagocytes, eosinophils, mast cells, and lymphocytes, spreads along the respiratory tract, leading to tissue damage. Mast cells and eosinophils are commonly recognized for their detrimental role in allergic reactions on activation through the high- and low-affinity receptors for IgE FcɛRI. These cells rapidly produce and secrete many of the mediators responsible for the typical symptoms of asthma and rhinitis. However, increasing amount of evidence demonstrate that mast cells and leukocytes have vital roles in host defense against pathogenesis. Histological methods are used to study leukocytes and receptor expression pattern in different respiratory tract compartments. The overall aim of this review was to understand the relationship between upper and lower respiratory tract inflammation and remodeling in patients with allergic and non-allergic asthma and rhinitis. In conclusion, this review discusses the relationship between the upper and lower airway in respiratory disease and focuses on the effect of respiratory processes on laryngeal inflammation, remodeling, function, and symptoms; however, they also have a central role in the initiation of the allergic immune response. Our findings suggest that there are differences that contribute to the development of immunopathological mechanisms of these clinically distinct forms of asthma, rhinitis, and chronic obstructive pulmonary disease.

Abstract
Persistent rhinitis (PR) is a chronic disease that affects millions of people. However, it lacks of a useful method, which can indicate the actual severity of the inflammation in PR patients. This study was designed to seek an examination which could reflect the actual severity of PR disease. The serum Phadiatop test, ECP level, four-phase rhinomanometry, and acoustic rhinometry were assessed in 91 adult patients with PR and 10 healthy controls. The serum total IgE was determined in some of the patients and all of the controls. The patients were divided into four groups: ARWO, ARWTO, NARWO and NARWTO. 40% (22/55) of AR and 33.3% (13/36) of NAR patients never complained of persistent nasal obstruction. Serum ECP levels were increased in the ARWO group. Serum total IgE was significantly elevated in the AR groups. MCA(1-Min) and MCA(1-T) were significantly reduced in the ARWO, ARWTO, and NARWO groups. NV(6-Min) and NV(6-T) were decreased in all PR groups, but only some of these differences were significant. In the ARWO group, MCA(2-Min) (r = -0.252), MCA(2-T) (r = -0.377), NV(6-Min) (r = -0.32), and NV(6-T) (r = -0.311) had significant relationships with serum ECP. We recommend acoustic rhinometry as a useful routine tool for the diagnosis of PR, even among patients without persistent subjective nasal obstruction. This technique might reveal the actual status of nasal congestion. An elevated serum ECP level might indicate severe AR and is negatively correlated with the results of acoustic rhinometry.

Abstract
Eosinophils localize to and release their granule proteins in close association with nerves in patients with asthma and rhinitis. These conditions are associated with increased neural function. In this study the effect of the individual granule proteins on cholinergic neurotransmitter expression was investigated. Eosinophil peroxidase (EPO) upregulated choline acetyltransferase (ChAT) and vesicular acetylcholine transporter (VAChT) gene expression. Fluorescently labeled EPO was seen to bind to the IMR-32 cell surface. Both Poly-L-Glutamate (PLG) and Heparinase-1 reversed the up-regulatory effect of EPO on ChAT and VAChT expression and prevented EPO adhesion to the cell surface. Poly-L-arginine (PLA) had no effect on expression of either gene, suggesting that charge is necessary but insufficient to alter gene expression. EPO induced its effects via the activation of NF-κB. MEK inhibition led to reversal of all up-regulatory effects of EPO. These data indicate a preferential role of EPO signaling via a specific surface receptor that leads to neural plasticity.

Abstract
OBJECTIVE We aimed to evaluate the relationship between swimming pool pollutants and allergic rhinitis in swimming pool workers. MATERIALS AND METHODS Twenty-seven indoor pool workers (group 1) and 49 control subjects (group 2) were enrolled in the study. A skin prick test was performed and a nasal smear was obtained from each subject to evaluate rhinitis. RESULTS When the groups were compared in terms of epithelial cells, group 1 had significantly more epithelial cells than group 2. When the groups were compared with regard to eosinophils, group 1 had significantly more eosinophils than group 2. The skin prick test results for both groups were not significantly different. CONCLUSION Indoor pool workers showed severe symptoms of rhinitis and eosinophilic nasal cytology, likely due to chlorine. Nasal cytology is an easy-to-administer diagnostic test and can be used to follow up rhinitis in indoor pool workers, along with nasal endoscopy, a detailed clinical history and a skin prick test.

Abstract
In this study, we investigated the effects of Naju Jjok (Polygonum tinctorium Lour., NJJ) on interleukin (IL)-32 and thymic stromal lymphopoietin (TSLP) levels associated with allergic rhinitis (AR). Using female BALB/c mice, we created an animal model of ovalbumin (OVA)-induced AR. Prior to the callenge with OVA, the mice were administered, either nasally or orally with NJJ. In addition, we also used the eosinophilic cells line, Eol-1, stimulated with granulocyte‑macrophage colony-stimulation factor (GM-CSF). The mRNA and protein levels of inflammatory cytokines and markers [interleukin (IL)-32, IL-4, macrophage-inflammatory protein-2 (MIP-2), intercellular adhesion molecule-1 (ICAM-1), and cyclooxygenase-2 (COX-2)] were measured by RT-PCR and western blot analysis, respectively and serum levels were measured by ELISA. The increased levels of IL-32 in the mice with AR and in the stimulated eosinophilic cell line, Eol-1, were significantly reduced by NJJ. TSLP levels were also decreased following the oral administration of NJJ. Mice orally administered NJJ showed markedly alleviated clinical symptoms, such as a reduced number of nasal rubs, decreased spleen weight, decreased serum immunoglobulin E (IgE) levels and decreased serum histamine levels. The oral administration of NJJ significantly decreased the IL-4 levels, while increasing the interferon-γ levels in the spleen. The increased number of eosinophils and mast cells infiltrating the nasal mucosal tissue of the mice with AR were decreased following the oral administration of NJJ. NJJ effectively attenuated caspase-1 activity in the mice with AR and in the stimulated Eol-1 cells. The oral administration of NJJ significantly reduced the levels of inflammatory markers, such as MIP-2, ICAM-1 and COX-2. Furthermore, the intranasal administration of NJJ significantly reduced the early phase response to allergen exposure, such as nasal rubs, IgE production and histamine release, as well as the late phase responses, such as the expression of inflammatory markers. In conclusion, these data demonstrate that NJJ may play a regulatory role in nasal inflammation.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) is a multifactorial disease; the underlying mechanisms of cell signalling are not fully understood. STAT3 (signal transducer and activator of transcription 3) is a phosphokinase and a key signalling molecule implicated in cell cycle regulation. We studied the distribution and expression of STAT3 to examine the role of STAT3 in the pathogenesis of CRSwNP. METHODS We investigated tissue samples of the nasal polyps and inferior turbinate of patients with CRSwNP as well as samples of the inferior turbinate of subjects without chronic sinusitis. The expression levels of STAT3 and its activated form pSTAT3 were analysed using Western blotting, protein array, DNA microarray and immunohistochemistry. RESULTS No significant differences were found in STAT3-mRNA levels between the samples of nasal polyps and inferior turbinates of the same patient. However, the amount of pSTAT3 was increased in the polyp tissue compared to the inferior turbinates from both CRSwNP patients and control subjects (p < 0.01), indicating an activation of STAT3 in polyps. We identified a varying distribution pattern of pSTAT3; pSTAT3 was primarily found in superficial epithelial cells but not in the basal layer of the epithelium of the turbinate, whereas pSTAT3 was located in all layers of the epithelium of the polyp and mostly noted in the basal layer. CONCLUSIONS Our results of the activation and varying localisation of STAT3 and its phosphorylated form in nasal polyps suggest that pSTAT3 plays a crucial role in the proliferative development of nasal polyps.

Abstract
Asthma imposes considerable patient and economic burdens, with the most severe cases causing the greatest affliction. Identifying stimuli that worsen asthma severity is an essential step to controlling both disease morbidity and the lessening economic impact. This study provides the first mechanistic investigation into how acute ethanol exposure will increase asthma severity in a murine model of mild cockroach allergen (CRA)-induced asthma. Outbred mice were sensitized to induce mild allergic asthma, with intratracheal CRA exposures on days 0 and 14. On day 21 mice were gavaged with water or 32% ethanol, and the third allergen exposure was given 30 min post-gavage. Asthmatic responses were measured at several time-points up to 42 h after the third allergen challenge. Ethanol-gavaged mice showed increased asthma severity within 90 min post-allergen challenge, with exacerbations lasting for 24 h. Ethanol caused greater airways obstruction, including an eightfold increase in epithelial cell mucin and increased mucus plugs, resulting in a 50% reduction in bronchiole patency. Ethanol gavage also induced significant increases in airways hyperreactivity. While T helper type 1 (Th1) and Th2 cytokines were not altered by ethanol gavage, pulmonary neutrophil and eosinophil recruitment were augmented. This increase was associated with increased chemokine production. Administration 2 h prior to ethanol gavage of a neutralizing antibody cocktail to keratinocyte-derived chemokine, macrophage inflammatory protein-2, eotaxin-1 and eotaxin-2 prevented ethanol-induced eosinophil recruitment and airways hyperreactivity. These data provide evidence that acute alcohol exposure immediately prior to a mild allergen-triggered asthmatic episode will exacerbate asthma severity mediated by increased production of chemokines.

Eosinophil recruitment to nasal nerves after allergen challenge in allergic rhinitis. Clin Immunol 2013; 147:50-57.

Abstract
In allergen challenged animal models, eosinophils localize to airway nerves leading to vagally-mediated hyperreactivity. We hypothesized that in allergic rhinitis eosinophils recruited to nasal nerves resulted in neural hyperreactivity. Patients with persistent allergic rhinitis (n=12), seasonal allergic rhinitis (n=7) and controls (n=10) were studied. Inferior nasal turbinate biopsies were obtained before, 8 and 48h after allergen challenge. Eight hours after allergen challenge eosinophils localized to nerves in both rhinitis groups; this was sustained through 48h. Bradykinin challenge, with secretion collection on the contralateral side, was performed to demonstrate nasal nerve reflexes. Twenty fourhours after allergen challenge, bradykinin induced a significant increase in secretions, indicating nasal hyperreactivity. Histological studies showed that nasal nerves expressed both vascular cell adhesion molecule-1 (VCAM-1) and chemokine (C-C motif) ligand 26 (CCL-26). Hence, after allergen challenge eosinophils are recruited and retained at nerves and so may be a mechanism for neural hyperreactivity.

Abstract
Eosinophils are the principal effector cells involved in the pathogenesis of allergic inflammation. We conducted a study to investigate the validity of the nasal smear examination for detecting eosinophilia in patients with allergic rhinitis. Our study group was made up of 50 patients with allergic rhinitis and 50 age- and sex-matched controls without allergic rhinitis. Smears were obtained from nasal secretions in both groups and then fixed, stained, and studied under light microscopy. Statistical analysis revealed that the odds ratio for eosinophilia positivity in nasal smears in the rhinitis group was 25.61 with a 95% confidence interval of 8 to 78. The sensitivity, specificity, positive predictive value, and negative predictive value of this test were 74, 90, 88, and 77%, respectively. We conclude that the nasal eosinophilia test is highly specific and moderately sensitive in diagnosing allergic rhinitis, and that it therefore can be used as an easy, noninvasive, and inexpensive procedure for screening patients and for conducting epidemiologic studies of this disorder.
