We have characterized previously the expression of the chemokines eotaxin, MCP-5, RANTES, and MCP-1 (mRNA and/or protein), and correlated this with the leukocytes migrating to the lung during a murine model of lung inflammation ((5), (16)). From these experiments, we concluded that MCP-1 mRNA expression paralleled the accumulation of monocytes/macrophages in this organ, both events occurring predominantly at early stages of the response (day 15). Also, eotaxin mRNA expression paralleled lung eosinophilia predominantly at late stages (day 21). In contrast, other chemokines, such as RANTES or MCP-5, were expressed throughout the inflammatory reaction. This underlines the contribution of chemokines at different stages of the response.. From the work presented here, we first conclude that eosinophil recruitment and development of BHR in this model system involve the action of both eosinophilic (eotaxin, RANTES, MCP-5, and MIP-1α) and noneosinophilic chemokines (MCP-1). This indicates the absence of ...

TY - JOUR. T1 - Interleukin-12 inhibits eotaxin secretion of cultured primary lung cells and alleviates airway inflammation in vivo. AU - Ye, Yi Ling. AU - Huang, Wan Ching. AU - Lee, Yueh L.. AU - Chiang, Bor Luen. PY - 2002. Y1 - 2002. N2 - The mechanisms that cause the inflammation of airway and lung tissue in asthma have been studied extensively. It is noted that type 1 T helper cell (Th1)-related cytokines could decrease the accumulation of eosinophils in lung tissue and relieve airway constriction. But the therapeutic mechanisms of Th1 cytokines remain unclear. In this study, interleukin-12 (IL-12) DNA plasmid as a therapeutic reagent was delivered intravenously. Bronchoalveolar lavage (BAL) fluids were collected from IL-12 treated and control mice, and analyzed for cell composition and eotaxin level. The results showed that IL-12 DNA plasmid could effectively inhibit eosinophilia and airway inflammation in vivo. The level of eotaxin in BAL fluid also decreased. To further investigate the ...

Background: Patients with severe asthma are less sensitive to oral or inhaled corticosteroids. Relative corticosteroid insensitivity has been shown in peripheral blood mononuclear cells and alveolar macrophages in these patients.. Aims and objectives: Determine the response of corticosteroids in airway smooth muscle cells (ASMCs) of severe asthma, in terms of suppression of cytokine-induced chemokine release and mRNA expression, and investigate the underlying mechanisms.. Methods: ASMCs of non-asthmatics (NA; 12), patients with non-severe (NSA; 10) or severe asthma (SA; 10) were pretreated with dexamethasone (Dex; 10-10-10-6 M) followed by stimulation with TNF-α at 10 ng/mL. IL-8 and eotaxin release determined by ELISA; mRNA quantified by RT-PCR. p65 NF-κB recruitment to gene promoters measured by ChIP assay; p38, JNK, and ERK expression measured by Western blot..

Background: MCP-1 (CCL2), MCP-3 (CCL7), and eotaxin (CCL11) are genes for CC chemokines clustered on the long arm of chromosome 17. Previous studies have implicated these chemokines in monocyte recruitment, viral replication, and anti-HIV cytotoxic T cell responses. An epidemiological analysis identified genetic variants influencing HIV-1 transmission and disease progression. Methods: Genomic DNA from over 3000 participants enrolled in five natural history cohorts in the United States were analyzed. Nine single nucleotide polymorphisms (SNP) covering 33 kb containing these three genes were genotyped using the polymerase chain reaction. Distortions in allele, genotype, and haplotype frequencies were assessed with respect to HIV-1 transmission and rates of disease progression using categorical and survival analyses. Results: Extensive linkage disequilibrium was observed. Three SNP (−2136T located in theMCP-1 promoter region, 767G in intron 1 of MCP-1, and −1385A in the Eotaxin promoter) were nearly

Eosinophils are specialized myeloid cells associated with allergy and helminth infections. Blood eosinophils demonstrate circadian cycling, as described over 80 years ago, and are abundant in the healthy gastrointestinal tract. Although a cytokine, interleukin (IL)-5, and chemokines such as eotaxins mediate eosinophil development and survival, and tissue recruitment, respectively, the processes underlying the basal regulation of these signals remain unknown. Here we show that serum IL-5 levels are maintained by long-lived type 2 innate lymphoid cells (ILC2) resident in peripheral tissues. ILC2 cells secrete IL-5 constitutively and are induced to co-express IL-13 during type 2 inflammation, resulting in localized eotaxin production and eosinophil accumulation. In the small intestine where eosinophils and eotaxin are constitutive, ILC2 cells co-express IL-5 and IL-13; this co-expression is enhanced after caloric intake. The circadian synchronizer vasoactive intestinal peptide also stimulates ILC2 cells

What, then, are those secret ingredients in blood that age the brain? According to Sakura Minami of the San Carlos-based biotech company Alkahest, one is eotaxin, a ligand for the C-C chemokine receptor type 3 (CCR3). Using proteomics approaches, Minami and colleagues saw that eotaxin shot up in the blood with age. Also known as CCL11, eotaxin is known to play a role in inflammation, for example in the recruitment of eosinophils upon CCR3 engagement. Given that these infection-fighting white blood cells can become damaging in allergic conditions such as asthma, CCR3 is an established drug target.. The researchers previously demonstrated that injecting eotaxin into young mice caused neurogenesis in the dentate gyrus to slow to a trickle, and that neutralizing eotaxin with an antibody blocked this effect (Aug 2011 news). At SfN, Minami reported preclinical findings from efforts to stifle the consequences of age-related eotaxin elevation. Rather than target eotaxin directly, Alkahest scientists ...

Previous investigations have demonstrated a link between elevated levels of eosinophils, eosinophil activation, and adult IBD. However, there have been conflicting data regarding the individual contribution of the eosinophil-selective chemokines eotaxin-1 and eotaxin-2 in eosinophil recruitment in IBD. In the present study we demonstrate the following: 1) that eosinophil numbers are elevated in pediatric UC and that their level correlates with disease severity; 2) eotaxin-1 and not eotaxin-2 or eotaxin-3 is up-regulated in lesional colonic biopsy samples of pediatric UC patients; and 3) eotaxin-1 mRNA expression correlates with colonic eosinophil levels in pediatric UC. Using a chemical-induced colonic injury model, we define that eotaxin-1, and not eotaxin-2, is critical for eosinophil recruitment and that eotaxin-1 is predominantly derived from intestinal macrophages. Consistent with our experimental analysis, we show that eotaxin-1 is predominantly expressed by intestinal macrophages; ...

Clinical studies have demonstrated a link between the eosinophil-selective chemokines, eotaxins (eotaxin-1/CCL11 and eotaxin-2/CCL24), eosinophils, and the inflammatory bowel diseases, Crohns disease and ulcerative colitis (UC). However, the cellular source and individual contribution of the eotaxins to colonic eosinophilic accumulation in inflammatory bowel diseases remain unclear. In this study we demonstrate, by gene array and quantitative PCR, elevated levels of eotaxin-1 mRNA in the rectosigmoid colon of pediatric UC patients. We show that elevated levels of eotaxin-1 mRNA positively correlated with rectosigmoid eosinophil numbers. Further, colonic eosinophils appeared to be degranulating, and the levels positively correlated with disease severity. Using the dextran sodium sulfate (DSS)-induced intestinal epithelial injury model, we show that DSS treatment of mice strongly induced colonic eotaxin-1 and eotaxin-2 expression and eosinophil levels. Analysis of eosinophil-deficient mice ...

Asthma is associated with eosinophilic airway inflammation and eosinophils are believed to be important in the pathogenesis of asthma. IL-5 has been considered the central mediator for eosinophilic proliferation, differentiation and eosinophilic inflammation, but results of recent studies suggest that besides IL-5, eotaxin may contribute to the pathogenesis of asthma. Eotaxin is CC chemokine first isolated from guinea pig bronchoalveolar lavage. It selectively binds to a specific receptor (CCR3) highly expressed on eosinophils, basophils, and mast cells being important in the pathogenesis of asthma. Eotaxin is produced mainly by epithelial cells of lung and gut, to mediate organ preferential attraction of eosinophils. Production of eotaxin is stimulated by IL-4, IL-13, TNF-α. Human eotaxin family includes: eotaxin-1 (CCL11), eotaxin-2 (CCL24) and eotaxin-3 (CCL26). It seems that eotaxin-3 may be expressed following allergen challenge. Studies with glucocorticosteroids have shown some inhibitory ...

It is now generally accepted that DPPIV acts as an important regulator of multiple physiological processes. It catalyzes the release of dipeptides from the N-terminus of circulating hormones, neuropeptides, and chemokines. Moreover, DPPIV is engaged in T cell-dependent immune responses and has been associated with cell adhesion and tumor metastasis (19, 23, 24). As DPPIV appears to act at a checkpoint of blood glucose homeostasis via potentiation of GLP-1-mediated stimulation of the entero-insular-axis and concomitant release of insulin, it has emerged as a target for the treatment of type 2 diabetes (4). At present, several DPPIV inhibitors are in the late stage of clinical development and some of them have reached the market for this indication (25). However, based on its ubiquitous expression and pleiotropic functions, systemic and continuous pharmacological blockade of DPPIV might act as a double-edged sword, as not only the beneficial release of insulin is increased but also immune ...

Patients with asthma demonstrate circadian variations in the airway inflammation and lung function. Pinealectomy reduces the total inflammatory cell number in the asthmatic rat lung. We hypothesize that melatonin, a circadian rhythm regulator, may modulate the circadian inflammatory variations in asthma by stimulating the chemotaxins expression in the lung epithelial cell. Lung epithelial cells (A549) were stimulated with melatonin in the presence or absence of TNF-α(100 ng/ml). RANTES (Regulated on Activation Normal T-cells Expressed and Secreted) and eotaxin expression were measured using ELISA and real-time RT-PCR, eosinophil chemotactic activity (ECA) released by A549 was measured by eosinophil chemotaxis assay. TNF-α increased the expression of RANTES (307.84 ± 33.56 versus 207.64 ± 31.27 pg/ml of control, p = 0.025) and eotaxin (108.97 ± 10.87 versus 54.00 ± 5.29 pg/ml of control, p = 0.041). Melatonin(10-10 to 10-6M) alone didnt change the expression of RNATES (204.97 ± 32.56 pg/ml) and

Eosinophil accumulation is a distinctive feature of lung allergic inflammation. Here, we have used a mouse model of OVA (ovalbumin)-induced pulmonary eosinophilia to study the cellular and molecular mechanisms for this selective recruitment of eosinophils to the airways. In this model there was an early accumulation of infiltrating monocytes/macrophages in the lung during the OVA treatment, whereas the increase in infiltrating T-lymphocytes paralleled the accumulation of eosinophils. The kinetics of accumulation of these three leukocyte subtypes correlated with the levels of mRNA expression of the chemokines monocyte chemotactic peptide-1/JE, eotaxin, and RANTES (regulated upon activation in normal T cells expressed and secreted), suggesting their involvement in the recruitment of these leukocytes. Furthermore, blockade of eotaxin with specific antibodies in vivo reduced the accumulation of eosinophils in the lung in response to OVA by half. Mature CD4+ T-lymphocytes were absolutely required for ...

Osteoarthritis (OA) is characterized by the degradation of articular cartilage, marked by the breakdown of matrix proteins. Studies demonstrated the involvement of chemokines in this process, and some may potentially serve as diagnostic markers and therapeutic targets; however, the underlying signal transductions are not well understood. We investigated the effects of the CC chemokine eotaxin-1 (CCL11) on the matrix metalloproteinase (MMP) expression and secretion in the human chondrocyte cell line SW1353 and primary chondrocytes. Eotaxin-1 significantly induced MMP-3 mRNA expression in a dose-dependent manner. Inhibitors of extracellular signal-regulated kinase (ERK) and p38 kinase were able to repress eotaxin-1-induced MMP-3 expression. On the contrary, Rp-adenosine-3,5-cyclic monophosphorothioate (Rp-cAMPs), a competitive cAMP antagonist for cAMP receptors, and H-89, a protein kinase A (PKA) inhibitor, markedly enhanced eotaxin-1-induced MMP-3 expression. These results suggest that MMP-3 expression

Airway eosinophilia is considered a central event in the pathogenesis of asthma. The toxic components of eosinophils are thought to be important in inducing bronchial mucosal injury and dysfunction. Previous studies have suggested an interaction between nitric oxide (NO) and chemokines in modulating eosinophil functions, but this is still conflicting. In the present study, we have carried out functional assays (adhesion and degranulation) and flow cytometry analysis of adhesion molecules (VLA-4 and Mac-1 expression) to evaluate the interactions between NO and CC-chemokines (eotaxin and RANTES) in human eosinophils. Eosinophils were purified using a percoll gradient followed by immunomagnetic cell separator. Cell adhesion and degranulation were evaluated by measuring eosinophil peroxidase (EPO) activity, whereas expression of Mac-1 and VLA-4 was detected using flow cytometry. At 4 h incubation, both eotaxin (100 ng/ml) and RANTES (1000 ng/ml) increased by 133% and 131% eosinophil adhesion, respectively.

PY - 2015. Y1 - 2015. N2 - Eosinophilic esophagitis (EoE) is considered to be a chronic antigen-driven disease whereby food and/or aeroallergens induce a chronic inflammatory infiltrate in the esophagus, resulting in pathological hyperplasia of the epithelia and muscular layers, and fibrosis of the lamina propria (referred to collectively as remodelling) and the symptoms of dysphagia and food impaction. EoE shares features with other atopic conditions of asthma and atopic dermatitis, such as a TH2 cytokine milieu and a mixed inflammatory infiltrate of eosinophils, mast cells and lymphocytes. Relatively distinct features include the strong male predominance amongst adult patients, and the expression of the eosinophil chemokine eotaxin 3.

Of the three types of leukocytes recruited, neutrophils, eosinophils, and macrophages, the most striking difference between BLTR−/− and wild-type mice occurred in eosinophil recruitment (Fig. 5 A). Neither group had substantial numbers of peritoneal eosinophils at baseline or 4 h after thioglycollate instillation. Peak numbers of eosinophils were seen in both groups at 48 h, but BLTR−/− mice recruited only 33% as many eosinophils to the inflamed peritoneum as wild-type mice at this time point (P , 0.005). Numbers of peritoneal eosinophils declined in both groups at 96 h, but BLTR−/− mice continued to have significantly fewer of these cells. At 96 h, BLTR−/− mice had only 20% as many eosinophils recovered from the peritoneal cavity as wild-type mice (P , 0.01).. Although the numbers of peritoneal neutrophils and macrophages appeared lower in the BLTR−/− mice at some time points, the differences from wild type did not reach statistical significance for either of these cell ...

Eosinophilia (e-o-sin-o-FILL-e-uh) is a higher than normal level of eosinophils. Eosinophils are a type of disease-fighting white blood cell. This condition most often indicates a parasitic infection, an allergic reaction or cancer.. You can have high levels of eosinophils in your blood (blood eosinophilia) or in tissues at the site of an infection or inflammation (tissue eosinophilia).. Tissue eosinophilia may be found in samples taken during an exploratory procedure or in samples of certain fluids, such as mucus released from nasal tissues. If you have tissue eosinophilia, the level of eosinophils in your bloodstream is likely normal.. Blood eosinophilia may be detected with a blood test, usually as part of a complete blood count. A count of more than 500 eosinophils per microliter of blood is generally considered eosinophilia in adults. A count of more than 1,500 eosinophils per microliter of blood that lasts for several months is called hypereosinophilia.. Eosinophils play two roles in your ...

The elevation of intracellular cyclic AMP by phosphodiesterase (PDE)4 inhibitors in eosinophils is associated with inhibition of the activation and recruitment of these cells. We have previously shown that systemic treatment with the PDE4 inhibitor rolipram effectively inhibt eosinophil migration in guinea pig skin. In the present study we compare the oral potency and efficacy of the PDE4 inhibitors rolipram, RP 73401 and CDP 840 on allergic and PAF-induced eosinophil recruitment. Rolipram and RP 73401 were equally effective and potent when given by the oral route and much more active than the PDE4 inhibitor CDP 840. We suggest that this guinea pig model of allergic and mediator-induced eosinophil recruitment is both a sensitive and simple tool to test the efficacy and potency of PDE4 inhibitors in vivo ...

Median cervico-vaginal levels of IL-6, Eotaxin, IP-10, MCP-1, MIP-1α, MIP-1β, and TNFα were higher than corresponding serum cytokines, significantly so for IL-6 and IP-10. Cervico-vaginal and serum cytokines were not correlated, but cytokines from the same fluid were correlated. ICCs for most serum cytokines were ≤0.40, while ICCs were higher in cervico-vaginal cytokines (range 0.52-0.83). IP-10 and Eotaxin had the highest ICCs for both cytokine sources. In adjusted models, PM10 was positively associated with serum cytokines IL-6, IP-10, MIP-1β and Eotaxin but inversely associated with cervico-vaginal cytokine TNFα, IP-10, MIP-1β, MCP-1 and Eotaxin, controlling for false discovery rate.
