Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is an inflammatory disease of the nose and paranasal sinuses characterized by the presence of nasal polyps. The symptoms produced by the presence of nasal polyps such as nasal obstruction, nasal discharge, facial pain, headache, and loss of smell cause a worsening in the quality of life of patients. The source of the nasal polyps remains unclear, although it seems to be due to a chronic inflammation process in the sinonasal mucosa. Fibroblasts, the main cells in connective tissue, are intimately involved in the inflammation processes of various diseases; to this end, we carried out a systematic review to evaluate their inflammatory role in nasal polyps. Thus, we evaluated the main cytokines produced by nasal polyp-derived fibroblasts (NPDF) to assess their involvement in the production of nasal polyps and their involvement in different inflammatory pathways. The results of the review highlight the inflammatory role of NPDF through the secretion of various cytokines involved in the T1, T2, and T3 inflammatory pathways, as well as the ability of NPDF to be stimulated by a multitude of substances. With these findings, the fibroblast is positioned as a new potential therapeutic target in the treatment of CRSwNP.

Abstract
BACKGROUND Allergic rhinitis (AR) is a common immunoglobulin E-mediated immune response involved various cell types, while the role of nasal fibroblasts (NFs) in the pathogenesis of AR is less understood. PURPOSE The study aimed to uncover the gene expression profile of AR-derived NFs and the potential mechanism for the changed phenotype of AR-NFs. RESEARCH DESIGN The primary NFs were isolated from 3 AR patients (AR-NFs) and 3 controls (Ctrl-NFs), and the proliferation, migration and interleukins production abilities of NFs were detected respectively. RNA-sequence was used to identify differentially expressed genes (DEGs) in AR-NFs. Transcription factor (TF) regulatory network and bioinformatic analyses were both conducted to clarify the biological roles of DEGs including the TFs. The DEG with the highest validated |fold change (FC)| value, detected by qPCR, was selected for further confirmation. RESULTS AR-NFs showed a higher proliferation and migration abilities as well as released higher levels of IL-33 and IL-6, compared to Ctrl-NFs. A total of 729 DEGs were screened out in AR-NFs. TF regulatory network indicated that BARX homeobox 1 (BARX1) and forkhead box L1 were the major node TFs. Bioinformatic analyses showed that a large number of DEGs including several target genes of BARX1 were both enriched cytokine-related GO terms, and immune- or inflammation-related pathways. BARX1 had the highest |FC| value, and silencing BARX1 in AR-NFs resulted in the significant downregulation of proliferation and migration abilities, and the production of interleukins. CONCLUSIONS Our study for the first time provided the gene expression profile of AR-derived NFs, and BARX1 could be developed as a potent target to alleviate the pathogenesis of AR.

Berberine induces anti-atopic dermatitis effects through the downregulation of cutaneous EIF3F and MALT1 in NC/Nga mice with atopy-like dermatitis. Biochem Pharmacol 2021; 185:114439.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease with severe pruritus. Berberine, a naturally occurring isoquinoline alkaloid, has anti-inflammatory effects. This study investigated the effects and molecular mechanisms of berberine on AD-like symptoms in mice. In this study, NC/Nga mice with atopy-like dermatitis (dermatitis mice), fibroblast and mast cells were used. In dermatitis mice, intermittent oral administrations of berberine 3 times a week for 12 days inhibited skin symptom, itching, cutaneous infiltration of eosinophils and mast cells, and the expression of cutaneous eotaxin, macrophage migration inhibitory factor (MIF) and IL-4. Berberine also attenuated IL-4/MIF-induced eotaxin in fibroblasts and allergen-induced MIF and IL-4 in mast cells. In mast cells, the GeneChip® microarray showed that antigen increased the expression of EIF3F and MALT1, inhibited by berberine. The siRNAs for them inhibited the expression of MIF and IL-4 in antigen-stimulated mast cells. These results suggest that berberine improves AD-like symptoms through the inhibition of the eotaxin and pro-inflammatory cytokine expression and the related inflammatory cell recruitment. It is also suggested that the downregulation of EIF3F and MALT1 by berberine is involved in suppressing the cytokine expression. Taken together, berberine or berberine-containing crude drugs are expected to contribute to the improvement of AD symptoms.

The regulatory role of SFRP5/WNT5A axis in allergic rhinitis through inhibiting JNK pathway activation and lowering mucin generation in human nasal epithelial cells. Exp Mol Pathol 2020; 118:104591. [PMID: 33285209 DOI: 10.1016/j.yexmp.2020.104591] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Revised: 09/17/2020] [Accepted: 12/01/2020] [Indexed: 12/29/2022]
Abstract
Allergic rhinitis (AR) is tightly associated with type 2 inflammation. SFRP5 combined with WNT5A mainly inhibits chronic inflammatory response, atherosclerosis, and other metabolic disorders. However, the effect of SFRP5/WNT5A axis on recombinant human interleukin-13 (rhIL-13)-induced inflammation has not been studied. In this study, we aimed to investigate whether secreted frizzled-related protein 5 (SFRP5) could modulate the production of cytokines relevant to eosinophil infiltration and mucin secretion through blocking the activation of Wnt family 5A (WNT5A) signaling pathway. A mouse model of AR demonstrated low expression of SFRP5 and high expression of WNT5A, and indicated that the number of eosinophil and goblet cells was increased, concomitant with elevated IL-13, colony stimulating factor 2 (CSF2), chemokine ligand 11 (CCL11), Mucin 4, and Mucin 5AC levels. Furthermore, lentivirus-SFRP5 overexpression up-regulated the expression of SFRP5 but down-regulated WNT5A level, and inhibited the activation of JNK pathway via decreasing p-JNK1/2 (Thr183/Tyr185) and p-c-Jun (Ser73) protein expressions in rhIL-13-treated human nasal epithelial cells (HNEpCs). Noticeably, SFRP5 overexpression markedly reduced rhIL-13-induced inflammatory protein and mucin generation through lowered CSF2, CCL11, Mucin 4, as well as Mucin 5AC levels. Taken together, these findings confirmed the regulatory role of SFRP5/WNT5A axis in rhIL-13-mediated inflammatory response in HNEpCs.

Abstract
The aim of this study is to determine whether AST2017-01 which consists of Rumex crispus and Cordyceps militaris would improve atopic dermatitis (AD). We analyzed anti-AD effects of AST2017-01 and chrysophanol, a bioactive compound of AST2017-01, using a 2,4-dinitrofluorobenzene-induced AD murine model. AST2017-01 and chrysophanol relieved clinical severity in AD-like skin lesions and significantly decreased scratching behavior. The thickness of epidermis and infiltration of inflammatory cells in AD-like skin lesions were reduced by AST2017-01 or chrysophanol. AST2017-01 and chrysophanol significantly suppressed the levels of histamine, immunoglobulin E, thymic stromal lymphopoietin (TSLP), interleukin (IL)-4, IL-6, and tumor necrosis factor-α in serum of AD mice. The protein levels of TSLP, intercellular adhesion molecule-1, and macrophage inflammatory protein 2 were significantly inhibited in the skin lesions. The mRNA expressions of TSLP, thymus and activation-regulated chemokine/CCL17, and C-C chemokine receptor 3 were inhibited in the skin lesions by AST2017-01 or chrysophanol. In addition, AST2017-01 and chrysophanol significantly suppressed the expressions and activities of caspase-1 in the skin lesions. Taken together, these results suggest that AST2017-01 has beneficial effects on AD and may be used as a health functional food in AD.

Abstract
Naringenin (NG) has various beneficial properties, such as anti-cancer and anti-inflammatory effects. Thymic stromal lymphopoietin (TSLP) induces mast cell proliferation and inflammatory reactions. The aim of this study was to investigate the regulatory effect of NG on TSLP-induced mast cell proliferation and inflammatory reactions using human mast cell line (HMC-1) cells. HMC-1 cells were pre-treated with NG and then treated with TSLP. HMC-1 cells proliferation was determined by quantifying bromodeoxyuridine incorporation. Levels of anti-apoptotic and pro-apoptotic factors were analyzed by western blot analysis. The productions and mRNA expressions of interleukin (IL)-13 and tumour necrosis factor-α (TNF-α) were analyzed by ELISA and quantitative real-time PCR. We found that NG significantly attenuated HMC-1 cells proliferation and Ki-67 mRNA expression promoted by TSLP. NG significantly suppressed mRNA expression of TSLP receptor and IL-7 receptor α in TSLP-treated HMC-1 cells. NG significantly down-regulated levels of phosphorylated-signal transducer and activation of transcription 6 and murine double-minute 2 in TSLP-treated HMC-1 cells, up-regulated levels of cleaved poly ADP-ribose polymerase and p53 in TSLP-treated HMC-1 cells. Furthermore, NG significantly decreased the productions and mRNA expressions of IL-13 and TNF-α in TSLP-treated HMC-1 cells. These results suggest NG has an inhibitory effect on mast cell-mediated allergic inflammatory reactions.

Abstract
BACKGROUND Nasal epithelial cells and infiltrating eosinophils express tissue factor, and high thrombin activity and excess fibrin deposition are found in nasal secretion and in nasal polyp from patients with chronic rhinosinusitis with nasal polyp (CRSwNP). Activated coagulation factors play important roles not only in thrombosis but also in inflammation through interaction with protease-activated receptors (PAR). However, little is known about the effects of activated coagulation factors on the release of cytokines and extracellular matrix from nasal polyp fibroblasts (NPF). PURPOSE The purpose of this study was to analyze the expression of PARs, which are receptors for activated coagulation factors, on NPFs and to determine the roles of thrombin and activated coagulation factor X (FXa) in the release of cytokines and fibronectin from NPFs. METHODS NPFs were obtained from patients with CRSwNP, and the messenger RNA (mRNA) and protein expression of PARs in these NPFs were examined. We then investigated whether thrombin or FXa stimulates the release of transforming growth factor (TGF) beta 1, fibronectin, eotaxin-1, interleukin (IL) 6, or IL-8 from cultured NPFs. The effects of PAR agonists on the release of cytokines and fibronectin were also examined. RESULTS NPFs expressed the mRNA and proteins of all four PARs: PAR-1, PAR-2, PAR-3, and PAR-4. Both thrombin and FXa significantly stimulated the release of TGF beta 1, fibronectin, eotaxin-1, IL-6, and IL-8 from cultured NPFs. PAR-1 and PAR-2 agonists stimulated the secretion of TGF beta 1, fibronectin, eotaxin-1, IL-6, and IL-8. PAR-3 agonist stimulated the release of TGF beta 1, fibronectin, and eotaxin-1. PAR-4 agonist did not induce the release of these molecules. CONCLUSION NPFs play important roles in the pathophysiology of CRSwNP such as in nasal polyp formation and inflammatory cell infiltration by releasing cytokines and extracellular matrix proteins. Activated coagulation factors, thrombin and FXa, stimulate the release of these cytokines and fibronectin from NPFs via PARs.

Abstract
IL-4 and IL-13 are pleiotropic Th2 cytokines produced by a wide variety of different cell types and responsible for a broad range of biology and functions. Physiologically, Th2 cytokines are known to mediate host defense against parasites but they can also trigger disease if their activities are dysregulated. In this review we discuss the rationale for targeting the IL-4/IL-13 axes in asthma, atopic dermatitis, allergic rhinitis, COPD, cancer, inflammatory bowel disease, autoimmune disease and fibrotic disease as well as evaluating the associated clinical data derived from blocking IL-4, IL-13 or IL-4 and IL-13 together.

Abstract
Diffuse and unstoppable infiltration of brain and spinal cord tissue by neoplastic glial cells is the single most important therapeutic problem posed by the common glioma group of tumors: astrocytoma, oligoastrocytoma, oligodendroglioma, their malignant variants and glioblastoma. These neoplasms account for more than two thirds of all malignant central nervous system tumors. However, most glioma research focuses on an examination of the tumor cells rather than on host-specific, tumor micro-environmental cells and factors. This can explain why existing diffuse glioma therapies fail and why these tumors have remained incurable. Thus, there is a great need for innovation. We describe a novel strategy for the development of a more effective treatment of diffuse glioma. Our approach centers on gaining control over the behavior of the microglia, the defense cells of the CNS, which are manipulated by malignant glioma and support its growth. Armoring microglia against the influences from glioma is one of our research goals. We further discuss how microglia precursors may be genetically enhanced to track down infiltrating glioma cells.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is characterized by local inflammation of the sinonasal tissues. CRS patients with nasal polyps and asthma often develop acute exacerbation of sinonasal symptoms after upper respiratory tract infections. However, the influence of concomitant asthma on the nasal immune response to viral infection remains unclear. METHODS Specimens of nasal polyp and mucosal tissues were obtained from 3 groups of CRS patients (n = 14 per group): 1) patients without asthma (CRS group), 2) patients with aspirin-tolerant asthma (ATA group), and 3) patients with aspirin-intolerant asthma (AIA group). Nasal fibroblasts isolated from the specimens were stimulated with poly I:C. CXCL10 expression was analyzed by the quantitative real-time polymerase chain reaction and enzyme-linked immunoadsorbent assay. Biopsy specimens from CRS patients without asthma were subjected to immunohistochemistry for detection of T-bet and GATA-3 expression in CD3+ T cells by double labeling. RESULTS Nasal fibroblasts from the ATA and AIA groups showed significantly enhanced expression of CXCL10 mRNA and protein after poly I:C stimulation compared with cells from the CRS group and the control group (normal nasal mucosa). In addition to T helper (Th)2 cells, there was more abundant infiltration of Th1 cells into tissues from the AIA and ATA groups. CONCLUSIONS Our findings suggest that CRS associated with asthma may become intractable through the over-production of CXCL10 in response to viral infection.

Abstract
Background Oxidative Stress contributes to the pathogenesis of many diseases. The NRF2/KEAP1 axis is a key transcriptional regulator of the anti-oxidant response in cells. Nrf2 knockout mice have implicated this pathway in regulating inflammatory airway diseases such as asthma and COPD. To better understand the role the NRF2 pathway has on respiratory disease we have taken a novel approach to define NRF2 dependent gene expression in a relevant lung system. Methods Normal human lung fibroblasts were transfected with siRNA specific for NRF2 or KEAP1. Gene expression changes were measured at 30 and 48 hours using a custom Affymetrix Gene array. Changes in Eotaxin-1 gene expression and protein secretion were further measured under various inflammatory conditions with siRNAs and pharmacological tools. Results An anti-correlated gene set (inversely regulated by NRF2 and KEAP1 RNAi) that reflects specific NRF2 regulated genes was identified. Gene annotations show that NRF2-mediated oxidative stress response is the most significantly regulated pathway, followed by heme metabolism, metabolism of xenobiotics by Cytochrome P450 and O-glycan biosynthesis. Unexpectedly the key eosinophil chemokine Eotaxin-1/CCL11 was found to be up-regulated when NRF2 was inhibited and down-regulated when KEAP1 was inhibited. This transcriptional regulation leads to modulation of Eotaxin-1 secretion from human lung fibroblasts under basal and inflammatory conditions, and is specific to Eotaxin-1 as NRF2 or KEAP1 knockdown had no effect on the secretion of a set of other chemokines and cytokines. Furthermore, the known NRF2 small molecule activators CDDO and Sulphoraphane can also dose dependently inhibit Eotaxin-1 release from human lung fibroblasts. Conclusions These data uncover a previously unknown role for NRF2 in regulating Eotaxin-1 expression and further the mechanistic understanding of this pathway in modulating inflammatory lung disease.

Abstract
BACKGROUND AND PURPOSE IL-13 is a pleiotropic Th2 cytokine considered likely to play a pivotal role in asthma. Here we describe the preclinical in vitro and in vivo characterization of CAT-354, an IL-13-neutralizing IgG4 monoclonal antibody (mAb), currently in clinical development. EXPERIMENTAL APPROACH In vitro the potency, specificity and species selectivity of CAT-354 was assayed in TF-1 cells, human umbilical vein endothelial cells and HDLM-2 cells. The ability of CAT-354 to modulate disease-relevant mechanisms was tested in human cells measuring bronchial smooth muscle calcium flux induced by histamine, eotaxin generation by normal lung fibroblasts, CD23 upregulation in peripheral blood mononuclear cells and IgE production by B cells. In vivo CAT-354 was tested on human IL-13-induced air pouch inflammation in mice, ovalbumin-sensitization and challenge in IL-13 humanized mice and antigen challenge in cynomolgus monkeys. KEY RESULTS CAT-354 has a 165 pM affinity for human IL-13 and functionally neutralized human, human variant associated with asthma and atopy (R130Q) and cynomolgus monkey, but not mouse, IL-13. CAT-354 did not neutralize human IL-4. In vitro CAT-354 functionally inhibited IL-13-induced eotaxin production, an analogue of smooth muscle airways hyperresponsiveness, CD23 upregulation and IgE production. In vivo in humanized mouse and cynomolgus monkey antigen challenge models CAT-354 inhibited airways hyperresponsiveness and bronchoalveolar lavage eosinophilia. CONCLUSIONS AND IMPLICATIONS CAT-354 is a potent and selective IL-13-neutralizing IgG4 mAb. The preclinical data presented here support the trialling of this mAb in patients with moderate to severe uncontrolled asthma.

Abstract
Lactobacillus plantarum CJLP133 was isolated from Kimchi, a Korean fermented food, and its potential to improve mouse atopic dermatitis after onset was studied. Dermatitis was developed through house dust-mite extract application onto NC/Nga mice, and then CJLP133 feeding was started. CJLP133 suppressed dermatitis-like skin lesions and decreased high serum IgE levels through balancing between IL-4 and IFN-γ in serum. CJLP133 diminished skin thickening, mast cell accumulation into inflamed site, and lymph node enlargement. In lymph node cells, CJLP133 repressed secretion of T cell cytokines such as IFN-γ, IL-4, IL-5, and IL-10. However, CJLP133 decreased ratios of IFN-γ and IL-5 to IL-10 in lymph node cells, while it did not decrease ratios of IL-4 and IL-5 to IFN-γ. Conclusively, CJLP133 exhibited therapeutic potential for atopic dermatitis in mice through orderly increment of type 1 helper T cell activation and regulatory T cell activation. These results suggest that CJLP133 could treat human atopic dermatitis.

Abstract
CCL11/eotaxin-1 is a potent eosinophilic CC chemokine expressed by primary human fibroblasts. The combination of TGF-β1 and IL-13 synergistically increases CCL11 expression, but the mechanisms behind the synergy are unclear. To address this, human airway fibroblast cultures from normal and asthmatic subjects were exposed to IL-13 alone or TGF-β1 plus IL-13. Transcriptional (nuclear run-on) and posttranscriptional (mRNA stability) assays confirmed that transcriptional regulation is critical for synergistic expression of CCL11. TGF-β1 plus IL-13 synergistically increased STAT-6 phosphorylation, nuclear translocation, and binding to the CCL11 promoter as compared with IL-13 alone. STAT-6 small interfering RNA significantly knocked down both STAT-6 mRNA expression and phosphorylation and inhibited CCL11 mRNA and protein expression. Regulation of the IL-4Rα complex by TGF-β1 augmented IL-13 signaling by dampening IL-13Rα2 expression, overcoming IL-13's autoregulation of its pathway and enhancing the expression of CCL11. Our data suggest that TGF-β1 induced activation of the MEK/ERK pathway reduces IL-13Rα2 expression induced by IL-13. Thus, TGF-β1, a pleiotropic cytokine upregulated in asthmatic airways, can augment eosinophilic inflammation by interfering with IL-13's negative feedback autoregulatory loop under MEK/ERK-dependent conditions.

Abstract
Short palate, lung and nasal epithelium clone 1 (SPLUNC1) is enriched in normal airway lining fluid, but is significantly reduced in airway epithelium exposed to a Th2 cytokine milieu. The role of SPLUNC1 in modulating airway allergic inflammation (e.g., eosinophils) remains unknown. We used SPLUNC1 knockout (KO) and littermate wild-type (C57BL/6 background) mice and recombinant SPLUNC1 protein to determine the impact of SPLUNC1 on airway allergic/eosinophilic inflammation, and to investigate the underlying mechanisms. An acute ovalbumin (OVA) sensitization and challenge protocol was used to induce murine airway allergic inflammation (e.g., eosinophils, eotaxin-2, and Th2 cytokines). Our results showed that SPLUNC1 in the bronchoalveolar lavage fluid of OVA-challenged wild-type mice was significantly reduced (P < 0.05), which was negatively correlated with levels of lung eosinophilic inflammation. Moreover, SPLUNC1 KO mice demonstrated significantly higher numbers of eosinophils in the lung after OVA challenges than did wild-type mice. Alveolar macrophages isolated from OVA-challenged SPLUNC1 KO versus wild-type mice had higher concentrations of baseline eotaxin-2 that was amplified by LPS (a known risk factor for exacerbating asthma). Human recombinant SPLUNC1 protein was applied to alveolar macrophages to study the regulation of eotaxin-2 in the context of Th2 cytokine and LPS stimulation. Recombinant SPLUNC1 protein attenuated LPS-induced eotaxin-2 production in Th2 cytokine-pretreated murine macrophages. These findings demonstrate that SPLUNC1 inhibits airway eosinophilic inflammation in allergic mice, in part by reducing eotaxin-2 production in alveolar macrophages.

Abstract
Exposure to a strong T-helper 2 (Th2)-like environment during fetal development may promote allergy development. Increased cord blood (CB) levels of the Th2-associated chemokine CCL22 were associated with allergy development during the first 2 y of life. The aim of the present study was to determine whether CB Th1- and Th2-associated chemokine levels are associated with allergy development during the first 6 y of life, allowing assessment of respiratory allergic symptoms usually developing in this period. The CB levels of cytokines, chemokines, and total IgE were determined in 56 children of 20 women with allergic symptoms and 36 women without allergic symptoms. Total IgE and allergen-specific IgE antibody levels were quantified at 6, 12, 24 mo, and 6 y of age. Increased CB CCL22 levels were associated with development of allergic sensitization and asthma and increased CCL17 levels with development of allergic symptoms, including asthma. Sensitized children with allergic symptoms showed higher CB CCL17 and CCL22 levels and higher ratios between these Th2-associated chemokines and the Th1-associated chemokine CXCL10 than nonsensitized children without allergic symptoms. A pronounced Th2 deviation at birth, reflected by increased CB CCL17 and CCL22 levels, and increased CCL22/CXCL10 and CCL17/CXCL10 ratios might promote allergy development later in life.

Abstract
Macrophage migration inhibitory factor (MIF) is a pluripotent cytokine that has an essential role in the pathophysiology of experimental allergic inflammation. Recent findings suggest that MIF is involved in several allergic disorders, including atopic dermatitis (AD). In this study, the role of MIF in allergic skin inflammation was examined using a murine model of AD elicited by epicutaneous sensitization with ovalbumin (OVA). We observed the number of skin-infiltrating eosinophils to significantly increase in OVA-sensitized MIF transgenic (Tg) mice compared with their wild-type (WT) littermates. On the other hand, eosinophils were virtually absent from the skin of MIF knockout (KO) mice and failed to infiltrate their skin after repeated epicutaneous sensitization with OVA. The mRNA expression levels of eotaxin and IL-5 were significantly increased in OVA-sensitized skin sites of MIF Tg mice, but were significantly decreased in MIF KO mice in comparison with the levels in WT littermates. Eotaxin expression was induced by IL-4 stimulation in fibroblasts in MIF Tg mice, but not in MIF KO mice. These findings indicate that MIF can induce eosinophil accumulation in the skin. Therefore, the targeted inhibition of MIF might be a promising new therapeutic strategy for allergic skin diseases.

Abstract
Eotaxin plays a central role in the development of allergic disease, including atopic dermatitis, asthma, and nasal allergy. Interleukin (IL)-4 induces eotaxin production in normal human dermal fibroblasts. On the other hands, Transforming growth factor-beta (TGF-beta), a multifunctional regulatory cytokine, affects many biological functions, including fibroblast growth and differentiation and Th2 cytokine regulation. In this study, we investigated the effect of TGF-beta on IL-4-induced eotaxin production by normal human fibroblasts, as well as the effect of suplatast tosilate, an antiallergic drug that selectively inhibits Th2 cytokine production. Dermal fibroblast treatment with IL-4 and TGF-beta for 24 h increased eotaxin production and expression of eotaxin mRNA, as measured by enzyme-linked immunosorbent assay (ELISA) and reverse-transcriptase polymerase chain reaction (RT-PCR), respectively. TGF-beta synergistically up-regulated eotaxin production and eotaxin mRNA expression when stimulated with IL-4. Suplatast tosilate dose-dependently inhibited eotaxin production induced by IL-4 or IL-4 plus TGF-beta. These results suggest that TGF-beta may regulate skin allergic inflammation by up-regulating eotaxin production in dermal fibroblasts. Suplatast tosilate might suppress this inflammation by inhibiting eotaxin production.

Abstract
BACKGROUND Eotaxin, a CC chemokine, plays an important role in inflammation of airway allergic diseases. The authors investigated the activities of caffeic acid phenethyl ester (CAPE), the active component of propolis, in regulating eotaxin production in human lung fibroblast. MATERIAL AND METHODS The authors used human lung fibroblasts, CCD-11Lu cells, stimulated with interleukin-13 (IL-13) and tumor necrosis factor-alpha (TNF-alpha), to induce eotaxin secretion. The cells were treated with CAPE of different concentrations and pretreatment duration to check its inhibition in eotaxin production. Enzyme-linked immunosorbent assay (ELISA) was used to measure eotaxin secretion; electrophoretic mobility shift assay (EMSA) to check nuclear factor kappa B (NF-kappaB)-promoter binding; and Western blot to quantitate the cyplasmic inhibitor of NF-kappaB (IkappaB) and nuclear NF-kappaB p65. RESULTS CAPE inhibited the production of eotaxin in CCD-11Lu cells stimulated by IL-13 and TNF-alpha combination in a dose- and time-dependent manner. The authors also demonstrated CAPE to be able to inhibit NF-kappaB activation in CCD-11Lu cells. CONCLUSION The authors suggest that CAPE is a promising agent in controlling eosinophils influx in human airway.

Abstract
IL-13 and eotaxin play important, inter-related roles in asthma models. In the lungs, CysLT, produced by the 5-LO-LTC4S pathway, mediate some local responses to IL-13 and eotaxin; in bone marrow, CysLT enhance IL-5-dependent eosinophil differentiation. We examined the effects of IL-13 and eotaxin on eosinophil differentiation. Semi-solid or liquid cultures were established from murine bone marrow with GM-CSF or IL-5, respectively, and the effects of IL-13, eotaxin, or CysLT on eosinophil colony formation and on eosinophil differentiation in liquid culture were evaluated, in the absence or presence of: a) the 5-LO inhibitor zileuton, the FLAP inhibitor MK886, or the CysLT1R antagonists, montelukast and MK571; b) mutations that inactivate 5-LO, LTC4S, or CysLT1R; and c) neutralizing mAb against eotaxin and its CCR3 receptor. Both cytokines enhanced GM-CSF-dependent eosinophil colony formation and IL-5-stimulated eosinophil differentiation. Although IL-13 did not induce eotaxin production, its effects were abolished by anti-eotaxin and anti-CCR3 antibodies, suggesting up-regulation by IL-13 of responses to endogenous eotaxin. Anti-CCR3 blocked eotaxin completely. The effects of both cytokines were prevented by zileuton, MK886, montelukast, and MK571, as well as by inactivation of the genes coding for 5-LO, LTC4S, and CysLT1R. In the absence of either cytokine, these treatments or mutations had no effect. These findings provide evidence for: a) a novel role of eotaxin and IL-13 in regulating eosinophilopoiesis; and b) a role for CysLTRs in bone marrow cells in transducing cytokine regulatory signals.

Abstract
Dermatofibromas are benign dermal nodules usually seen on the extremities; however, whether a dermatofibroma is a reactive fibrous hyperplasia or a true neoplasm is still unclear. Fibrous type dermatofibromas might be regarded as the symptom of local fibrotic processes and thus present a possible model of local fibrosis. Interaction between proliferated dermatofibroma fibroblasts and overlying elongated epidermis suggests a relationship between keratinocytes and mesenchymal cells. We herein describe current insights into the pathogenesis of dermatofibromas and explore the possible involvement of immunocytes around fibroblasts and effector cells which play an important role in the development of dermatofibromas.

Abstract
Background The etiology of allergic fungal rhinosinusitis (AFRS) remains controversial. Initially thought to represent an immunoglobulin E (IgE)–mediated hypersensitivity to fungal antigens, additional data have implicated other non-IgE and cellular-mediated pathways. The aim of this study was to characterize T-helper type 1 (Th1) and Th2 immune responses of blood lymphocytes from AFRS patients by fungal antigen stimulation to help differentiate these possible pathways. Methods Peripheral blood mononuclear cells (PBMCs) isolated from AFRS patients (n = 10) and healthy controls (HCs; n = 11) were exposed to four different fungal extracts (Alternaria, Aspergillus, Cladosporium, and Penicillium) in duplicate. After a 72-hour incubation, the supernatants were analyzed for cytokine levels of three Th1 (interferon [IFN] gamma, interleukin [IL]-2, and tumor necrosis factor alpha) and three Th2 (IL-10, IL-5, and IL-4) cytokines by cytometric bead array flow cytometry. Serum fungal-specific IgE levels were measured by ImmunoCAP (Pharmacia Diagnostics, Kalamazoo, MI). Results Fungal extracts of Alternaria and Cladosporium stimulated higher levels of IL-5 from PBMCs in AFRS when compared with HCs (p < 0.05). IL-4 was also elevated for Alternaria in AFRS versus HCs (p < 0.05). A skewed Th2 response to fungal antigen exposure was confirmed by an elevated IL-5/IFN-gamma ratio in AFRS subjects (p < 0.05). Initial studies suggest a correlation between percent T-cell activation and IL-5 expression to IgE levels. Fungal antigens stimulated a notable but not statistically significant increase in IL-10 response in HCs. Conclusion In AFRS patients, fungal antigens stimulated T-cell activation, inducing a predominately Th2 immune response. Healthy controls expressed an inhibitory cytokine IL-10 when exposed to these fungal antigens, possibly serving as a protective response.

Abstract
Type I allergic diseases such as allergic rhinitis are caused by IgE-mediated humoral immune responses, while eosinophils also fulfill important roles in the etiology of IgE-mediated allergy. IL-21 regulates growth, differentiation, and function of T, B, and NK cells, while the production of IgE is also influenced by IL-21. In this study we examined whether IL-21 is capable of controlling IgE-mediated allergic reactions in vivo by using the allergic rhinitis mouse model that was established by repetitive sensitization and intranasal challenge with OVA. Intranasal administration with recombinant mouse IL-21 (rmIL-21) significantly reduced the number of sneezes, as well as the serum concentration of OVA-specific IgE, in comparison with that of untreated allergic mice. The rmIL-21 treatment also suppressed germline Cepsilon transcription in the nasal-associated lymphoid tissues, which may have, at least partly, resulted from the up-regulation of Bcl-6 mRNA caused by IL-21. Local expression of IL-4, IL-5, and IL-13 was also inhibited by the intranasal cytokine therapy whereas, in contrast, the expression of endogenous IL-21 mRNA was induced by exogenous rmIL-21. Moreover, IL-21 acted on nasal fibroblasts to inhibit production of eotaxin. This novel function of IL-21 may be associated with the attenuation of eosinophil infiltration into nasal mucosa that was revealed by histopathological observation. These results indicated that IL-21 nasal administration effectively ameliorated allergic rhinitis through pleiotropic activities, i.e., the prevention of IgE production by B cells and eotaxin production by fibroblasts.

Abstract
Blood eosinophilia and tissue eosinophilia are characteristic features of allergic inflammation and asthma, conditions associated with prominent production of T(H)2 cytokines IL-4, IL-5, and IL-13. In this review, we will consider recent advances in our understanding of the molecular mechanisms that promote expansion and differentiation of eosinophil progenitors in bone marrow, eosinophil recruitment in response to chemokine receptor 3 agonists eosinophil transit mediated by specific ligand-receptor interactions, and prolonged survival of eosinophils in peripheral tissues. Novel rational therapies including antiselectin and antichemokine receptor modalities designed to block eosinophil development and trafficking are discussed, together with the implications of recent clinical studies that have evaluated the efficacy of humanized anti-IL-5 mAb therapy.

Abstract
Scleroderma is a connective tissue disease with unknown etiology characterized by excessive deposition of extracellular matrix in the skin. Cellular infiltrates of certain immune cells and proinflammatory mediators are suggested to play a crucial role in cutaneous fibrosis, forming complicated networks between fibroblasts and immune cells via cell-cell communications. Tissue-selective trafficking of leukocytes is mediated by combinations of adhesion molecules and chemokines. Recent studies have shown that an increase in proinflammatory chemokines has been associated with the initiation and/or development of skin fibrosis/sclerosis, suggesting that chemokines and their receptors may be important mediators of inflammation and fibrosis in scleroderma. This review will focus on the roles of chemokines and their receptors during the process of cutaneous sclerosis and will also provide a current insight into the potential mechanisms of scleroderma.

Abstract
BACKGROUND/AIMS Recent studies documented that sensitization and exposure to cockroach allergens significantly increase children's asthma morbidity as well as severity, especially among inner city children. TNF-alpha has been postulated to be a critical mediator directly contributing to the bronchopulmonary inflammation and airway hyper-responsiveness in asthma. This study investigated whether an anti-TNF-alpha antibody would inhibit pulmonary inflammation and methacholine (Mch) hyper-responsiveness in a mouse model of asthma induced by a house dust extract containing both endotoxin and cockroach allergens. METHODS A house dust sample was extracted with phosphate-buffered saline and then used for immunization and two additional pulmonary challenges of BALB/c mice. Mice were treated with an intravenous injection of anti-TNF-alpha antibody or control antibody 1 h before each pulmonary challenge. RESULTS In a kinetic study, TNF-alpha levels within the bronchoalveolar lavage (BAL) fluid increased quickly peaking at 2 h while BAL levels of IL-4, IL-5, and IL-13 peaked at later time-points. Mch hyper-responsiveness was measured 24 h after the last challenge, and mice were killed 24 h later. TNF inhibition resulted in an augmentation of these Th2 cytokines. However, the allergic pulmonary inflammation was significantly reduced by anti-TNF-alpha antibody treatment as demonstrated by a substantial reduction in the number of BAL eosinophils, lymphocytes, macrophages, and neutrophils compared with rat IgG-treated mice. Mch hyper-responsiveness was also significantly reduced in anti-TNF-alpha antibody-treated mice and the pulmonary histology was also significantly improved. Inhibition of TNF significantly reduced eotaxin levels within the lung, suggesting a potential mechanism for the beneficial effects. These data indicate that anti-TNF-alpha antibody can reduce the inflammation and pathophysiology of asthma in a murine model of asthma induced by a house dust extract.

Abstract
Oncostatin-M (OSM) is an IL-6/gp130 family member that can stimulate the eosinophil-selective CC chemokine eotaxin-1 in vitro and eosinophil accumulation in mouse lung in vivo. The adhesion molecule VCAM-1 and eotaxin have been implicated in extravasation and accumulation of eosinophils into tissue in animal models of asthma. In this study, we investigated the role of OSM in regulation of VCAM-1 expression, and STAT6 tyrosine 641 phosphorylation in murine fibroblasts. OSM induced VCAM-1 expression in C57BL/6 mouse lung fibroblasts (MLF) and NIH 3T3 fibroblasts at the protein and mRNA level in vitro. OSM also induced STAT6 Y641 phosphorylation in MLF and NIH 3T3 fibroblasts, an activity not observed with other IL-6/gp130 cytokine family members (IL-6, leukemia inhibitory factor, cardiotropin-1, and IL-11) nor in cells derived from STAT6(-/-) mice (STAT6(-/-) MLF). STAT6 was not essential for OSM-induced VCAM-1 or eotaxin-1 as assessed in STAT6(-/-) MLF. Combination of IL-4 and OSM synergistically enhanced eotaxin-1 expression in MLF. IL-4 induction and the IL-4/OSM synergistic induction of eotaxin-1 was abrogated in STAT6(-/-) MLF, however, regulation of IL-6 was similar in -/- or wild-type MLF. Induction of VCAM-1 by OSM was diminished by pharmacological inhibitors of PI3K (LY294002) but not inhibitors of ERK1/2 (PD98059) or p38 MAPK (SB203580). These data support the role of OSM in eosinophil accumulation into lung tissue through eotaxin-1 and VCAM-1 expression and the notion that OSM is able to induce unique signal transduction events through its receptor complex of OSMR beta-chain and gp130.

Abstract
BACKGROUND IL-17E is a new TH2 cytokine that promotes airway eosinophilia in mice. IL-17E proinflammatory activity has been proposed to involve induction of cytokine and chemokine production. Recruitment of inflammatory cells may be mediated by tissue-resident cells. OBJECTIVE This study aimed to evaluate whether fibroblasts represent a target of IL-17E for the production of eosinophil active mediators in the lung. METHODS Expression of IL-17B receptor (IL-17BR), a receptor for IL-17E, was evaluated by immunofluorescent staining, Western blot, and real-time PCR in human primary lung fibroblasts. Mediator production was analyzed by using real-time PCR and ELISA after stimulation of fibroblasts with IL-17E alone or in combination with TNF-alpha and TGF-beta1. Expression of IL-17E and of eosinophil major basic protein was evaluated by immunohistochemistry in bronchial biopsies from subjects with asthma. RESULTS Human primary lung fibroblasts constitutively expressed IL-17BR. IL-17BR mRNA levels were increased in cells stimulated with TNF-alpha and decreased with TGF-beta1. IL-17E slightly upregulated CC chemokine ligand (CCL)-5, CCL-11, GM-CSF, and CXC chemokine ligand (CXCL)-8 mRNA in fibroblasts. Moreover, IL-17E and TNF-alpha synergistically induced GM-CSF and CXCL-8 mRNA. IL-17E also potentiated the upregulation of CXCL-8 transcripts observed with TGF-beta1. In contrast, TGF-beta1 decreased IL-17E-induced CCL-11 mRNA. The capacity of IL-17E to enhance GM-CSF and CXCL-8 responses to TNF-alpha was accompanied by production and secretion of both proteins by lung fibroblasts. Finally, IL-17E was detected in asthma in eosinophil-infiltrated bronchial submucosa. CONCLUSION IL-17E may contribute to the induction and maintenance of eosinophilic inflammation in the airways by acting on lung fibroblasts. This study supports a role for IL-17E in asthma pathophysiology.

Abstract
Scleroderma is a fibrotic condition characterized by immunologic abnormalities, vascular injury and increased accumulation of extracellular matrix (ECM) proteins in the skin. Although the etiology of scleroderma has not yet been fully elucidated, a growing body of evidence suggests that ECM overproduction by activated fibroblasts results from complex interactions among endothelial cells, lymphocytes, macrophages and fibroblasts, via a number of mediators, such as cytokines, chemokines and growth factors. For a better understanding of the pathophysiology of scleroderma, animal models are important tools. We established a murine model of cutaneous sclerosis by local treatment of bleomycin. This model reproduces several histological as well as biochemical aspects of human scleroderma. However, it must be emphasized that studying animal models cannot answer all the problems of human scleroderma. In this review, we introduce current insights into the pathogenesis of bleomycin-induced scleroderma, and discuss its contribution to our understanding of the pathogenesis of, and treatments for, human scleroderma.

Abstract
BACKGROUND Eotaxin-1 (CCL11) is a CC chemokine whose nasal eosinophilic chemotactic activity in vivo and in vitro has been demonstrated primarily using nasal allergen challenge models. The extension of these challenge findings to the in vivo setting has been limited. OBJECTIVE To obtain nasal lavage fluid from volunteers with perennial and seasonal (in- and out-of-season) allergic rhinitis (AR) and non-atopic non-rhinitic controls for the measurement of eotaxin-1 concentrations and to relate these findings to the symptomatic disease severity, the percentage of lavage eosinophils, and to alpha(2)-macroglobulin (alpha(2)-MG) lavage concentrations, as a marker of vascular permeability and an index of airway inflammation. METHODS Thirty-seven volunteers with AR (16 seasonal and 21 perennial) and 20 non-atopic non-rhinitic volunteers were recruited and phenotyped. Nasal lavage fluid was obtained by standardized protocol. The nasal lavage fluid concentrations of eotaxin and alpha(2)-MG were measured by ELISA, and differential cell counts performed on cytospins. RESULTS Eotaxin-1 nasal lavage fluid concentrations were significantly higher in both the perennial and seasonal (in-season) AR groups compared with the controls, and significantly related to the severity of symptom expression and to the percentage of lavage eosinophils. The lavage eosinophil counts were significantly higher in both the symptomatic rhinitis groups compared with the control groups and correlated with the lavage concentrations of alpha(2)-MG. alpha(2)-MG levels were significantly increased in seasonal (in-season) rhinitics compared with both non-atopic controls and seasonal (out-of-season) rhinitics. A significant correlation was observed between the levels of alpha(2)-MG and levels of eotaxin in the symptomatic allergic rhinitic groups. CONCLUSIONS This study clearly demonstrates the relevance of eotaxin-1 to the pathogenesis of naturally occurring AR.

Abstract
Allergic diseases result in a considerable socioeconomic burden. The incidence of allergic diseases, notably allergic asthma, has risen to high levels for reasons that are not entirely understood. With an increasing knowledge of underlying mechanisms, there is now more potential to target the inflammatory process rather than the overt symptoms. This focuses attention on the role of leukocytes especially Th2 lymphocytes that regulate allergic inflammation and effector cells where eosinophils have received much attention. Eosinophils are thought to be important based on the high numbers that are recruited to sites of allergic inflammation and the potential of these cells to effect both tissue injury and remodelling. It is hoped that future therapy will be directed towards specific leukocyte types, without overtly compromising essential host defence responses. One obvious target is leukocyte recruitment. This necessitates a detailed understanding of underlying mechanisms, particularly those involving soluble chemoattractants signals and cell-cell adhesion molecules.

Abstract
Scleroderma is a fibrotic condition characterized by immunologic abnormalities, vascular injury and increased accumulation of matrix proteins in the skin. Although the aetiology of scleroderma is not fully elucidated, a growing body of evidence suggests that extracellular matrix overproduction by activated fibroblasts results from complex interactions among endothelial cells, lymphocytes, macrophages and fibroblasts, via a number of mediators. Cytokines, chemokines and growth factors secreted by inflammatory cells and mesenchymal cells (fibroblasts and myofibroblasts) play an important role in the fibrotic process of scleroderma. Recently, we established a murine model of scleroderma by repeated local injections of bleomycin. Dermal sclerosis was induced in various mouse strains, although the intensity of dermal sclerosis varied among various strains. Histopathological and biochemical analysis demonstrated that this experimental murine scleroderma reflected a number of aspects of human scleroderma. Further investigation of the cellular and molecular mechanisms of inflammatory reaction, fibroblast activation and extracellular matrix deposition following dermal injury by bleomycin treatment will lead to the better understanding of the pathophysiology and the exploration of effective treatment against scleroderma. This review summarizes recent progress of the cellular and molecular events in the pathogenesis of bleomycin-induced scleroderma; moreover, further perspective by using this mouse model has been discussed.

Abstract
Pulmonary eosinophilia, a hallmark pathologic feature of allergic lung disease, is regulated by interleukin-13 (IL-13) as well as the eotaxin chemokines, but the specific role of these cytokines and their cooperative interaction are only partially understood. First, we elucidated the essential role of IL-13 in the induction of the eotaxins by comparing IL-13 gene-targeted mice with wild type control mice by using an ovalbumin-induced model of allergic airway inflammation. Notably, ovalbumin-induced expressions of eotaxin-1 and eotaxin-2 mRNA in the lungs were almost completely dependent upon IL-13. Second, in order to address the specific role of eotaxin-2 in IL-13-induced pulmonary eosinophilia, we generated eotaxin-2 gene-deficient mice by homologous recombination. Notably, in contrast to observations made in eotaxin-1-deficient mice, eotaxin-2-deficient mice had normal base-line eosinophil levels in the hematopoietic tissues and gastrointestinal tract. However, following intratracheal IL-13 administration, eotaxin-2-deficient mice showed a profound reduction in airway eosinophilia compared with wild type mice. Most interestingly, the level of peribronchial lung tissue eosinophils in IL-13-treated eotaxin-2-deficient mice was indistinguishable from wild type mice. Furthermore, IL-13 lung transgenic mice genetically engineered to be deficient in eotaxin-2 had a marked reduction of luminal eosinophils. Mechanistic analysis identified IL13-induced eotaxin-2 expression by macrophages in a distinct lung compartment (luminal inflammatory cells) compared with eotaxin-1, which was expressed solely in the tissue. Taken together, these results demonstrate a cooperative mechanism between IL-13 and eotaxin-2. In particular, IL-13 mediates allergen-induced eotaxin-2 expression, and eotaxin-2 mediates IL-13-induced airway eosinophilia.

Abstract
BACKGROUND There is growing evidence that eotaxin is a key mediator in the development of tissue eosinophilia. Fibroblasts are a major source of eotaxin. The severity of diseases with eosinophilic inflammation like nasal polyposis, atopic dermatitis and asthma, where Th2-type cytokines (IL-4 and IL-13) and TGF-beta are expressed locally, was shown to correlate with bacterial factors such as lipopolysaccharide (LPS) rather than allergen. OBJECTIVE We examined eotaxin production by nasal fibroblasts stimulated with IL-4 or IL-13 alone or in combination with LPS, and the effect of TGF-beta(1) on it. Moreover, we compared the magnitude of eotaxin produced by nasal fibroblasts with that produced by lung or skin fibroblasts. METHODS Fibroblast lines were established from human biopsy tissue. The expression of eotaxin mRNA was evaluated by RT-PCR. The amount of eotaxin in the supernatants was measured by ELISA. RESULTS IL-4, but not IL-13, synergized with LPS to produce eotaxin in a dose- and time-dependent manner. Sequential treatment of nasal fibroblasts with IL-4 and LPS did not have any effect. But when IL-4 and LPS were added together, synergy for eotaxin production was observed. Moreover, this synergy was observed in nasal and skin fibroblasts, but not in lung fibroblasts. The production of eotaxin by IL-4 and LPS was modulated by TGF-beta(1). CONCLUSION These results suggest that a co-stimulus like LPS is necessary for IL-4 to make a strong induction of eotaxin in eosinophilic inflammations such as nasal polyposis. Modulation by TGF-beta(1) may have important implications for the development of eosinophilic inflammation.

Abstract
Two interleukin 13 receptors (IL-13Rs) have been identified as IL-13Ralpha1 and IL-13Ralpha2. IL-13Ralpha1 is composed of a heterodimer consisting of IL-13Ralpha1 and IL-4 receptor alpha (IL-4Ralpha) as a signaling subunit. In contrast, IL-13Ralpha2 is known as a decoy receptor for IL-13. In this study, we investigated the expression of IL-13Rs on human fibroblasts. IL-13Ralpha2 was significantly up-regulated after stimulation with tumor necrosis factor-alpha (TNF-alpha) and/or IL-4. In contrast, IL-13Ralpha1 was constitutively detectable and was not up-regulated. After the induction of IL-13alpha2 by IL-4, STAT6 phosphorylation through IL-13Ralpha1 by IL-13 was inhibited. We also detected large intracellular pools of IL-13Ralpha2 in fibroblasts quantitatively. Furthermore, mobilization of the IL-13Ralpha2 protein stores from the cytoplasm to the cell surface was prevented by an inhibitor of protein transport, brefeldin-A. These results indicate that TNF-alpha and IL-4 synergistically up-regulate the expression of IL-13Ralpha2 decoy receptor on human fibroblasts by inducing gene expression and mobilizing intracellular receptors, and thus may down-regulate the IL-13 signaling.

Abstract
Nasal Polyps (NPs) are the most common mass lesions found in the nose. NPs cause airway obstruction, prevent normal sinus function, and can lead to infection of the eye, facial bones and central nervous system. The predominant cell type inhabiting NPs is the eosinophil, and the chemokine eotaxin is believed to play an important role in NP eosinophilia. The objective of this study was to localize and quantitate expression of eotaxin mRNA in human NPs. Total RNA was isolated from NPs that were collected from 5 patients who had undergone polypectomy. Portions of these polyps were also fixed in formalin, embedded in paraffin, and sectioned onto slides for use in in situ hybridization. Total RNA from one patient was used in a reverse transcriptase polymerase chain reaction using eotaxin specific primers to generate a human eotaxin cDNA. The eotaxin cDNA was cloned and used to generate probes for Northern blot analyses and for use in in situ hybridization (ISH). Eotaxin mRNA was detected by Northern analyses in all patient samples, though the relative expression level in each patient varied. ISH localized the expression of eotaxin mRNA specifically in eosinophils in 2 of the 3 patients in the study for whom the embedded polyp tissue appeared sufficiently well preserved for mRNA localization. Our findings suggest that eosinophilia in NPs is likely a self-amplification process whereby increasing numbers of eosinophils are recruited to enter the polyp as a result of production of eotaxin by eosinophils already within the polyp.

Abstract
BACKGROUND Allergic rhinitis is an inflammation involving T(H)2-type cytokine production, with pathologic eosinophil infiltration in the nasal mucosa. Although TNF-alpha is thought to be a pro-inflammatory cytokine, the relationship between TNF-alpha and allergic rhinitis has not been clarified. OBJECTIVES The role of TNF-alpha in a murine model of ovalbumin (OVA)-sensitized allergic rhinitis was investigated by using mice deficient in the gene encoding TNF-alpha (TNF-alpha(-/-) mice). METHODS Both wild-type (TNF-alpha(+/+)) and TNF-alpha(-/-) mice were sensitized with OVA by means of intraperitoneal injection. They were then challenged with intranasal OVA, and various allergic responses were assessed. RESULTS The production of OVA-specific IgE in the serum (P <.05) and the frequency of sneezes (P <.05) and nasal rubs (P <.05) decreased significantly in TNF-alpha(-/-) mice after OVA sensitization compared with that in TNF-alpha(+/+) mice (P <.05). The mRNA expression of IL-4, IL-10, and eotaxin in nasal mucosa in TNF-alpha(-/-) mice was also significantly suppressed compared with that in TNF-alpha(+/+) mice after OVA sensitization (P <.05). Furthermore, the expression of both endothelial-leukocyte adhesion molecule 1 and vascular cell adhesion molecule 1 mRNA in the nasal mucosa was significantly suppressed (P <.05), although intercellular adhesion molecule 1 mRNA expression did not decrease significantly in TNF-alpha(-/-) mice compared with that in TNF-alpha(+/+) mice after OVA sensitization. In addition, the effect of TNF-alpha on endothelial-leukocyte adhesion molecule 1 and vascular cell adhesion molecule 1 expression by means of Western blot analysis was compatible with the mRNA results. Pathologically, eosinophil infiltration in nasal mucosa was significantly restricted in TNF-alpha(-/-) mice compared with in TNF-alpha(+/+) mice after OVA sensitization (P <.05). CONCLUSION TNF-alpha is necessary for antigen-specific IgE production and for the induction of T(H)2-type cytokines and chemokines. Furthermore, TNF-alpha might be important for the expression of adhesion molecules to recruit eosinophils to the allergic inflammatory site. We conclude that the lack of TNF-alpha inhibited the development of allergic rhinitis.

Abstract
Accumulating data show that fibroblasts are important regulators in the development and maintenance of allergic airway inflammation. However, most studies so far have used individual recombinant cytokines in high concentrations, unlikely to be found in vivo. We aimed to investigate how cytokines produced by peripheral blood mononuclear cells (PBMC) affect fibroblast functions. Primary airway fibroblasts where incubated with allergen-stimulated or non-stimulated PBMC supernatants from allergic patients. The levels of cytokines in PBMC supernatants were measured and the expression of CD54, CD40 and CD106 as well as the production of eotaxin, interleukin (IL)-6 and IL-8 were assessed in fibroblasts. Although the levels of single cytokines measured in PBMC supernatants were low, a significant up-regulation of the surface molecules as well as of IL-6 and IL-8 production was found in fibroblasts cultured with allergen-stimulated PBMC supernatants as compared to non-stimulated, while the increase in eotaxin production was not significant. The evaluation of correlations between cytokines produced by PBMC and effects seen on fibroblasts did not indicate a crucial role for any single cytokine. Furthermore, the addition of comparably low concentrations of recombinant interferon (rIFN)-gamma or recombinant tumour necrosis factor (rTNF)-alpha did not induce the same effects as PBMC supernatants, the only exception being TNF-alpha as a direct inducer of CD54 expression. Our results show that synergistic mechanisms has a more important role than single mediators, highlighting important differences between in vitro experiments, where effects of individual mediators are studied, versus the actual situation in vivo.

Abstract
Cysteinyl leukotrienes (CysLTs) play an important role in eosinophilic airway inflammation. In addition to their direct chemotactic effects on eosinophils, indirect effects have been reported. Eotaxin is a potent eosinophil-specific chemotactic factor produced mainly by fibroblasts. We investigated whether CysLTs augment eosinophilic inflammation via eotaxin production by fibroblasts. Leukotriene (LT)C(4) alone had no effect on eotaxin production by human fetal lung fibroblasts (HFL-1). However, LTC(4) stimulated eotaxin production by IL-13-treated fibroblasts, thereby indirectly inducing eosinophil sequestration. Unstimulated fibroblasts did not respond to LTC(4), but coincubation or preincubation of fibroblasts with IL-13 altered the response to LTC(4). To examine the mechanism(s) involved, the expression of CysLT1R in HFL-1 was investigated by quantitative real-time PCR and flow cytometry. Only low levels of CysLT1R mRNA and no CysLT1R protein were expressed in unstimulated HFL-1. In contrast, stimulation with IL-13 at a concentration of 10 ng/ml for 24 h significantly up-regulated both CysLT1R mRNA and protein expression in HFL-1. The synergistic effect of LTC(4) and IL-13 on eotaxin production was abolished by CysLT1R antagonists pranlukast and montelukast. These findings suggest that IL-13 up-regulates CysLT1R expression, which may contribute to the synergistic effect of LTC(4) and IL-13 on eotaxin production by lung fibroblasts. In the Th2 cytokine-rich milieu, such as that in bronchial asthma, CysLT1R expression on fibroblasts might be up-regulated, thereby allowing CysLTs to act effectively and increase eosinophilic inflammation.

Abstract
OBJECTIVE Eotaxin-1 and eotaxin-2 are potent eosinophil chemotactic and activating peptides that may be implicated in the pathogenesis of the chronic allergic eye diseases vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC). The purpose of this study was to measure these chemokines in tear and mucus samples of active-disease patients and in vitro cultured conjunctival epithelial cells and fibroblasts. DESIGN Comparative, observational case series and in vitro study. PARTICIPANTS Sixteen patients with clinically active and untreated VKC or AKC, six age-matched control patients, and five nonactive seasonal allergic conjunctivitis patients. METHODS Tears were collected from the active VKC and AKC patients, and from the normal patients. Mucus was collected from six of these VKC patients. Tears were also collected from an additional five allergic patients after obtaining a positive reaction to conjunctival allergen challenge. Conjunctival epithelial cell and conjunctival fibroblast cultures were exposed to interleukin (IL)-4, IL-13, and tumor necrosis factor-alpha (TNF-alpha), or to combinations of these cytokines. MAIN OUTCOME MEASURES Levels of eotaxin-1 and eotaxin-2 in tears, mucus, and culture medium. RESULTS High levels of eotaxin-1 and eotaxin-2 were found in mucus of VKC patients, whereas only eotaxin-2 was found to have increased significantly in tears of VKC and AKC patients compared with those of normal patients. Mucus contained higher levels of chemokines than did tears. Both tear eotaxin-1 and eotaxin-2 were correlated significantly with the percent of eosinophils in tear fluid. Eotaxin-1 also was correlated significantly with the sum clinical score and corneal involvement in VKC patients. Conjunctival epithelial cells in culture did not produce eotaxin-1 or eotaxin-2, either at baseline or after cytokine exposure. Conjunctival fibroblasts produced eotaxin-1 only after exposure to IL-4, TNF-alpha, and the combination of IL-4 plus TNF-alpha or IL-13 plus TNF-alpha. CONCLUSIONS Eotaxin-1 and eotaxin-2 are implicated in eosinophil recruitment and in the pathogenesis of VKC and AKC. Cytokine-stimulated conjunctival fibroblasts may be one source of eotaxin-1 in severely allergic tissues.

Abstract
Oncostatin M (OSM) is a member of the IL-6/LIF (or gp130) cytokine family, and its potential role in inflammation is supported by a number of activities identified in vitro. In this study, we investigate the action of murine OSM on expression of the CC chemokine eotaxin by fibroblasts in vitro and on mouse lung tissue in vivo. Recombinant murine OSM stimulated eotaxin protein production and mRNA levels in the NIH 3T3 fibroblast cell line. IL-6 could regulate a small induction of eotaxin in NIH 3T3 cells, but other IL-6/LIF cytokines (LIF, cardiotrophin-1 (CT-1)) had no effect. Cell signaling studies showed that murine OSM, LIF, IL-6, and CT-1 stimulated the tyrosine phosphorylation of STAT-3, suggesting STAT-3 activation is not sufficient for eotaxin induction in NIH 3T3 cells. OSM induced ERK-1,2 and p38 mitogen-activated protein kinase phosphorylation in NIH 3T3 cells, and inhibitors of ERK (PD98059) or p38 (SB203580) could partially reduce OSM-induced eotaxin production, suggesting partial dependence on mitogen-activated protein kinase signaling. OSM (but not LIF, IL-6, or CT-1) also induced eotaxin release by mouse lung fibroblast cultures derived from C57BL/6 mice. Overexpression of murine OSM in lungs of C57BL/6 mice using an adenovirus vector encoding murine OSM resulted in a vigorous inflammatory response by day 7 after intranasal administration, including marked extracellular matrix accumulation and eosinophil infiltration. Elevated levels of eotaxin mRNA in whole lung were detected at days 4 and 5. These data strongly support a role of OSM in lung inflammatory responses that involve eosinophil infiltration.

Abstract
The study investigated the role of P-selectin in the responses of eosinophil transmigration and eotaxin generation in vivo elicited by interleukin (IL)-13, as compared with IL-4. Two murine models of leukocyte transmigration were used, migration into cytokine-stimulated peritoneal cavities and through stimulated cremasteric venules, as observed by intravital microscopy. In mice lacking P-selectin, eosinophil infiltration elicited by the cytokines in the peritonitis model was totally inhibited. In the cremaster muscle, however, although spontaneous leukocyte-rolling flux and stimulated leukocyte firm adhesion were inhibited by approximately 97% and approximately 48%, respectively, stimulated transmigration was unaffected. However, IL-13-induced leukocyte transmigration was totally blocked in P-selectin-deficient mice treated with an anti-alpha(4) integrin monoclonal antibody (mAb; PS/2). In comparison, treatment of wild-type mice with the anti-alpha(4) integrin mAb resulted in only partial suppression of IL-13-induced leukocyte transmigration. Significant levels of eotaxin were detected in response to IL-13/IL-4 in both tissues in P-selectin-deficient animals. In conclusion, the regulatory role of P-selectin in leukocyte transmigration elicited by IL-13 appears to be tissue-specific, a phenomenon that is independent of the ability of the cytokine to stimulate eotaxin generation.

Abstract
In addition to be involved in airway remodelling observed in asthmatic patients, lung fibroblasts may directly contribute to pulmonary inflammation through the release of mediators and through the expression of surface molecules involved in cell-cell interaction. The aim of the study was to evaluate whether two cytokines involved in asthma pathogenesis, IL-4 and TNF-alpha, could modulate the expression of adhesion molecules (VCAM-1 and ICAM-1) and the secretion of chemokines (eotaxin and MCP-1) related to eosinophil recruitment and activation. The constitutive expression of VCAM-1 by unstimulated fibroblasts was over 2-fold lower than that of ICAM-1 (P<0.05). Significant differences were also observed in the release of chemokines by unstimulated fibroblast, the levels of eotaxin being over 17-fold lower than those of MCP-1. Stimulation of the cells with IL-4 or TNF-alpha induced a dose-dependent increase in VCAM-1, while ICAM-1 was overexpressed only in culture stimulated by TNF-alpha (P<0.05) but not in those exposed to IL-4 (P>0.05 each comparison). In contrast, a significant increase in MCP-1 and eotaxin release was observed in the presence of TNF-alpha (P<0.05) but not of IL-4 (P>0.05). These data show that two 'proinflammatory' cytokines, such as IL-4 and TNF-alpha, may have different and complementary effects on functions involved in the cross-talking between fibroblasts and eosinophils.

Abstract
Chronic diseases may involve an "innate" response followed by an adaptive immune response, of a Th1 or Th2 variety. Little is known regarding the interactions of these responses. We hypothesized that TGF-beta1 (innate response factor associated with wound repair) in combination with IL-13 (Th2 factor) might augment inflammatory processes associated with asthma. Airway fibroblasts were cultured from asthmatic subjects and normal controls. These fibroblasts were exposed to TGF-beta1 and IL-13 alone or in combination, and eotaxin-1 expression and production were evaluated. At 48 h, eotaxin-1 production was markedly increased with the combination of TGF-beta1 and IL-13 (p < 0.0001) compared with either stimulus alone. mRNA increased slightly at 1 h with IL-13 or TGF-beta1 plus IL13, peaked, and became significantly increased over IL-13 alone at 24 h. Protein was measurable from 6 h with IL-13 and TGF-beta1 plus IL-13, but greater levels were measured over time with the combination. Actinomycin ablated the increase in mRNA and protein seen with IL-13 alone and with TGF-beta1 plus IL-13. Cycloheximide blocked the increase in mRNA at 6 h in both conditions, but also blocked the increase at 24 h with TGF-beta1 plus IL-13. STAT-6 was rapidly activated with both IL-13 and the combination, without difference. Finally, eotaxin-1-positive fibroblasts were identified in severe asthma biopsies in greater numbers than in normals. These results support the concept that interactions of innate and adaptive immune systems may be important in promoting the tissue eosinophilia of asthma, particularly in those with more severe disease.

Abstract
Short-term preoperative radiotherapy in combination with surgery has been shown to decrease the rate of local recurrence in rectal cancer patients. The effects of this type of radiotherapy on the histopathology of rectal carcinoma has been hitherto unknown. Since various histopathological factors are associated with prognosis, the study of alterations induced by irradiation is an important issue. This paper examines the histopathology of resection specimens from 1306 patients who were treated in a randomized trial that evaluated the benefits of preoperative radiotherapy. In this trial, patients were treated with short-term radiotherapy (5 x 5 Gy) and operated on within 5 days after radiation. Histopathological parameters were determined by the Pathology Review Committee of the trial and we compared tumours of patients with and without preoperative radiotherapy. Tumours of patients who were treated with preoperative radiotherapy were smaller, more often mucinous carcinomas (13% versus 7%, p < 0.001) and more often poorly differentiated (35% versus 24%, p<0.001). After radiotherapy, there was less inflammatory reaction around the tumour (extensive in 7% versus 18%, p<0.001), which was mainly caused by a decrease in T lymphocytes and neutrophil granulocytes. The fibroblastic reaction was more pronounced in the radiotherapy group (extensive in 22% versus 10%, p <0.001). Remarkable histological alterations occurred within a week after 5 days of irradiation of rectal carcinomas. The prognostic value of these factors therefore needs to be re-evaluated for irradiated patients.
