Eosinophil peroxidase is an enzyme found within the eosinophil granulocytes, innate immune cells of humans and mammals. This oxidoreductase protein is encoded by the gene EPX, expressed within these myeloid cells. EPO shares many similarities with its orthologous peroxidases, myeloperoxidase (MPO), lactoperoxidase (LPO), and thyroid peroxidase (TPO). The protein is concentrated in secretory granules within eosinophils. Eosinophil peroxidase is a heme peroxidase, its activities including the oxidation of halide ions to bacteriocidal reactive oxygen species, the cationic disruption of bacterial cell walls, and the post-translational modification of protein amino acid residues. The major function of eosinophil peroxidase is to catalyze the formation of hypohalous acids from hydrogen peroxide and halide ions in solution. For example: H2O2 + Cl− → HOCl + H2O Hypohalous acids formed from halides or pseudohalides are potent oxidizing agents. The open reading frame of human eosinophil peroxidase was ...
Eosinophil peroxidase and myeloperoxidase use hydrogen peroxide to produce hypobromous acid and hypochlorous acid. These powerful oxidants may damage the lungs if they are produced as part of the inflammatory response in asthma. The aim of this study was to determine if peroxidases generate hypohalous acids in the airways of individuals with stable asthma, and if they affect lung function. Sputum was induced from patients with mild to moderate asthma and from healthy controls. Eosinophil peroxidase, myeloperoxidase, chlorinated and brominated tyrosyl residues, and protein carbonyls were measured in sputum supernatants. Eosinophil peroxidase protein was significantly elevated in asthmatic subjects whereas myeloperoxidase protein was not. There was significantly more 3-bromotyrosine (Br-Tyr) in proteins from the sputum of asthmatics compared to controls (0.79 vs. 0.23 mmol Br-Tyr/mol Tyr; medians p , .0001). Levels of 3-chlorotyrosine (0.23 vs. 0.14 mmol Cl-Tyr/mol Tyr; medians p = .11) and ...

FIGURE 6 Dose-dependent effect of lipopolysaccharide (LPS) on neutrophil-induced trans-basement membrane migration of eosinophils in severe asthmatics. Neutrophils (2×104 cells) from severe asthmatics were stimulated with various concentrations of LPS (0.01-100 µg·mL−1), and then placed into the lower compartment of a chamber with a Matrigel-coated Transwell insert. Eosinophils (1×105 cells) from severe asthmatics were added to the upper compartment. After 120 min of incubation, migrated eosinophils in the lower chamber were measured by eosinophil peroxidase assays (n=4). Data are presented as mean±sem. *: p,0.05 versus spontaneous migration (0 µg·mL−1 LPS) by Tukey test; **: p,0.01 versus spontaneous migration (0 µg·mL−1 LPS) by Tukey test. ...
Among the human heme-peroxidase family, myeloperoxidase (MPO) has a unique disulfide-linked oligomeric structure resulting from multi-step processing of the pro-protein monomer (proMPO) after it exits the endoplasmic reticulum (ER). Related family members undergo some, but not all, of the processing steps involved with formation of mature MPO. Lactoperoxidase has its pro-domain proteolytically removed and is a monomer in its mature form. Eosinophil peroxidase undergoes proteolytic removal of its pro-domain followed by proteolytic separation into heavy and light chains and is a heterodimer. However, only MPO undergoes both these proteolytic modifications and then is further oligomerized into a heterotetramer by a single inter-molecular disulfide bond. The details of how and where the post-ER processing steps of MPO occur are incompletely understood. We report here that T47D breast cancer cells stably transfected with an MPO expression plasmid are able to efficiently replicate all of the processing steps
Eosinophils are major effector cells in type 2 inflammatory responses and become activated in response to IL-4 and IL-33, yet the molecular mechanism remains unclear. We examined the direct effect of these cytokines on eosinophils and demonstrated that murine eosinophils respond to IL-4 and IL-33 by phosphorylation of STAT-6 and NFkB, respectively. RNA sequencing analysis of murine eosinophils indicated that IL-33 regulates 519 genes, whereas IL-4 regulates only 28 genes, including 19 IL-33-regulated genes. Interestingly, IL-33 induced eosinophil activation via two distinct mechanisms, IL-4 independent and IL-4 secretion/auto-stimulation dependent. Anti-IL-4 or anti-IL-4Ra antibody-treated eosinophils, as well as Il4- or Stat6-deficient eosinophils, had attenuated protein secretion of a subset of IL-33-induced genes, including Retnla and Ccl17. However, the induction of most IL-33-regulated transcripts (e.g. Il6 and Il13) was IL-4 independent and blocked by NFkB inhibition. Indeed, IL-33 induced the

The airway epithelium made up of ciliated cells and goblet cells forming a tight barrier to the outside world. Inset: In a healthy airway epithelium, goblet cells secrete mucin proteins that are incorporated into a thick gel that coats the luminal side of airways and is propelled out of the lung by the beating of cell-surface cilia. In asthma and other airway disease, this mucociliary defense mechanism does not function as effectively and mucus can become trapped and form mucus plugs. Four general mechanisms of mucus dysfunction have been described, including the following: (a) mucus dehydration leading to collapse of the periciliary brush mucus layer, (b) excess production of mucins such as Muc5AC, (c) abnormal tethering of mucus strands to the goblet cell surface, and (d) mucus crosslinking during inflammation. In the presence of eosinophilic airway inflammation, eosinophil peroxidase (EPX), together with other oxidant molecules, can crosslink mucus strands, leading to a more viscous gel that ...
Eosinophils are bone marrow-derived cells that differentiate in the bone marrow and migrate into the peripheral blood primarily under the regulation of interleukin (IL)-5
IL-33 has emerged as an important cytokine in allergic diseases, largely because of its potential to activate cells that are hallmarks of allergy, including eosinophils, mast cells, and basophils (31). Outside of allergy, IL-33 has also been proposed to be involved in bacterial and viral infections, tumorigenesis, autoimmunity, fibrosis (32), and more recently, hematopoiesis (23, 33). In this article, we define a previously unappreciated mechanism for IL-33 in regulating eosinophil commitment.. Our data demonstrate that IL-33 directs the eosinophil compartment by expanding the EoPre frequency and upregulating IL-5Rα to license the responsiveness of these precursors to IL-5 within the bone marrow. Importantly, the defects in basal eosinophil populations we identified in the IL-33 KO and ST2 KO mice strongly implicate a homeostatic contribution of this cytokine that functions outside of a disease pathogenesis setting. Indeed, the previously defined function of IL-33 as an alarmin released upon ...

Eosinophil Granule Proteins: Proteins found in EOSINOPHIL granules. They are primarily basic proteins that play a role in host defense and the proinflammatory actions of activated eosinophils.
Essentially pure preparations of normal density eosinophils obtained from patients with hypereosinophilic syndrome (HES) were stimulated with complement factor 5a (C5a), platelet-activating factor (PAF), FMLP and neutrophil-activating peptide (NAP-1/IL-8). Three responses were studied, the transient rise in cytosolic free calcium concentration ([Ca2+]i) (derived from indo-1 fluorescence), shape changes (measured by laser turbidimetry), and exocytosis of eosinophil peroxidase (EPO) (assessed by H2O2/luminol-dependent chemiluminescence). Responses were obtained with all four agonists, but C5a and PAF were by far more potent than FMLP and NAP-1/IL-8, which induced only minor effects. Pretreatment of the cells with pertussis toxin attenuated [Ca2+]i changes, EPO release and, to a lesser extent, shape changes, indicating that GTP-binding proteins of Gi-type are involved in receptor-dependent signal transduction processes leading to these responses. A clear dissociation was observed in the control of ...
The existence of a functional receptor for secretory component (SC) on the eosinophil membrane might explain the preferential degranulation induced by secretory IgA (sIgA) when compared to serum IgA. Indeed, flow cytometry analysis revealed that purified human SC could bind to a subpopulation (4-59%) of blood eosinophils purified from 19 patients with eosinophilia. Binding of radiolabeled human SC could be competitively inhibited using unlabeled SC or secretory IgA but not with serum IgA or IgG. Immunoprecipitation and immunosorbent chromatography using human SC revealed the presence of a major component at 15 kDa in eosinophil extracts as well as in culture supernatants but not in neutrophils. The 15-kDa protein eluted from the human SC immunosorbent was able to bind to SC or to sIgA but not to serum IgA. Eosinophils preincubated with human SC or sIgA released eosinophil cationic protein (ECP) and eosinophil peroxidase (EPO) after addition of anti-SC or anti-IgA monoclonal antibody as respective cross
Eosinophils, sometimes called eosinophiles or, less commonly, acidophils, are a variety of white blood cells and one of the immune system components responsible for combating multicellular parasites and certain infections in vertebrates.[citation needed] Along with mast cells and basophils, they also control mechanisms associated with allergy and asthma. They are granulocytes that develop during hematopoiesis in the bone marrow before migrating into blood, after which they are terminally differentiated and do not multiply. These cells are eosinophilic or "acid-loving" due to their large acidophilic cytoplasmic granules, which show their affinity for acids by their affinity to coal tar dyes: Normally transparent, it is this affinity that causes them to appear brick-red after staining with eosin, a red dye, using the Romanowsky method. The staining is concentrated in small granules within the cellular cytoplasm, which contain many chemical mediators, such as eosinophil peroxidase, ribonuclease ...
BACKGROUND. The link between mucus plugs and airflow obstruction has not been established in chronic severe asthma, and the role of eosinophils and their products in mucus plug formation is unknown. METHODS. In clinical studies, we developed and applied a bronchopulmonary segment-based scoring system to quantify mucus plugs on multidetector computed tomography (MDCT) lung scans from 146 subjects with asthma and 22 controls, and analyzed relationships among mucus plug scores, forced expiratory volume in 1 second (FEV1), and airway eosinophils. Additionally, we used airway mucus gel models to explore whether oxidants generated by eosinophil peroxidase (EPO) oxidize cysteine thiol groups to promote mucus plug formation. RESULTS. Mucus plugs occurred in at least 1 of 20 lung segments in 58% of subjects with asthma and in only 4.5% of controls, and the plugs in subjects with asthma persisted in the same segment for years. A high mucus score (plugs in ≥ 4 segments) occurred in 67% of subjects with ...

The Bayer H1 haematology analyser automatically counts leucocyte populations on the basis of their differential peroxidase staining.22 By incorporating additional software we have adapted this analyser to accurately determine both eosinophil and neutrophil position on a peroxidase dot plot. This software allows gating of stained neutrophil and eosinophil populations, and determination of the amount of absorption (plotted on thex axis) and scatter (plotted on they axis) of light produced by individual leucocytes.. In this study experiments were performed to validate the methodology, with the quantitation of neutrophil and eosinophil absorption and scatter co-ordinates being shown to be repeatable and reproducible. The method has the benefits of using whole blood, it is rapid, and does not require sample processing. Furthermore, neutrophil and eosinophil assays can be performed on blood stored at room temperature for up to eight hours, and do not depend on the venepuncture method or amount of ...
Siglecs are type I transmembrane proteins expressed primarily on leukocytes. Among them is Siglec-8, a CD33 subfamily member that is selectively expressed on the cell surface of human eosinophils. Siglec-8 has an intracellular immunoreceptor tyrosine-based inhibitory motif (ITIM) and an immunoreceptor tyrosine-based switch motif (ITSM), putatively responsible for signal transduction. In cytokine-activated eosinophils, Siglec-8 binding causes apoptosis with increased mitochondrial damage and ROS production, but exact signaling mechanisms are unknown. Using a mAb (2C4) against Siglec-8 in combination with small molecule inhibitors, we first examined Siglec-8-mediated apoptosis and ROS production by flow cytometry after 24 hr IL-5 priming (30 ng/mL) of human eosinophils. We observed that 2C4-mediated eosinophil apoptosis was inhibited by PP1 and SU6656 (Src kinase inhibitors), ibrutinib (Btk inhibitor), LY294002 (PI3K inhibitor), GF109203x (PKC inhibitor), and sodium orthovanadate (a protein ...

Everyone whose life has been touched by an eosinophil associated disease has a story to share. Here, we feature perspectives from patients and family members
Eosinophils are potent inflammatory cells with numerous immune functions including antigen presentation and exacerbation of inflammatory responses through their capacity to release a range of largely preformed cytokines and lipid mediators. as well as degranulation evidenced by increased CD63 surface expression secretion of eosinophil cationic protein (ECP) and eosinophil derived neurotoxin (EDN). Moreover NK cells significantly and dose dependently increased eosinophil apoptosis as shown by 4-Chlorophenylguanidine hydrochloride annexin V and propidium iodide (PI) staining. Direct contact was necessary for eosinophil degranulation and apoptosis. 4-Chlorophenylguanidine hydrochloride Increased expression of phosphorylated extracellular signal-regulated kinase (ERK) C13orf1 in cocultured eosinophils and inhibition of eosinophil CD63 expression by pharmacologic inhibitors suggest that MAPK and PI3K pathways are involved in NK cell-induced eosinophil degranulation. Finally we showed that NK cells ...

N2 - Eosinophils, through their ability to generate an array of potent mediators, are thought to be the major effector cells in a number of conditions, including parasitic infection, asthma, and other allergic diseases. The mechanism(s) by which eosinophils, as opposed to neutrophils, accumulate at inflammatory sites is unknown. One possible mechanism would be an eosinophil-specific pathway of adhesion to vascular endothelium. In this study we have demonstrated that human eosinophils, but not neutrophils, constitutively express alpha-4-beta-1 (CD49d/CD29). Expression was not increased on low density eosinophils or normal density cells stimulated with platelet-activating factor. Eosinophils, but not ...
The intestinal immune system is composed of a complex network of cells that must balance immunity and tolerance to ingested food antigens, pathogens, and the microbiota. Derangements in intestinal homeostasis lead to allergy, autoimmunity, and inflammatory bowel diseases. Although eosinophils have long been appreciated to be qualitatively abundant in the intestine, even in the absence of any pathology, a functional role for them there has remained elusive.. In this months Society of Mucosal Immunology Featured Paper, Indigenous Enteric Eosinophils Control DCs to Initiate a Primary Th2 Immune Resonse in vivo, Chu et al. shed light on "The curious case of the intestinal eosinophil." First, the authors quantitated and analyzed eosinophils along the intestinal tract and showed that eosinophils are most abundant within the small intestine. To evaluate the contribution of intestinal eosinophils to mucosal immunity, the authors analyzed eosinophils in a model of peanut food allergy and anaphylaxis. In ...
Eosinophils are multifunctional leukocytes playing important roles in allergic inflammation and helminth infections. Although most research concerning eosinophils has focused on understanding their function in the blood and lung, it should be noted that eosinophils are much more abundant in the lamina propria (LP) of gastrointestinal (GI) tract than in other tissues. In this study, CD11bhighCD11cint cells, representing an almost pure population of eosinophils, were successfully isolated from the small intestinal LP wild type mice and this subset was not found in the LP of the genetically engineered eosinophil-deficient dblGATA mice. The CD11bhighCD11cint cells had prominent eosinophilic granules in the cytoplasm. Electron microscopic examination demonstrated that a significant fraction of the cytoplasmic granules were bi-compartmental, with an electron-dense or -lucent crystalline core. LP eosinophils express substantially lower levels of L-selectin, PSGL-1, integrin α4β7, and IL-5Rα and ...

Following maturation and/or activation, eosinophils (as well as their progenitors) are mobilised, released from bone marrow into circulation and trafficked to tissue sites. A large proportion of these mature eosinophils will remain in bone marrow [8][17]. Once eosinophils enter circulation, they have a half-life of approximately 8-18 hours[8]. Under normal conditions, the vast majority of eosinophils are located in tissues (the tissue/blood eosinophil ratio is about 100:1) and upon gaining entrance to a tissue, most do not recirculate[3]. They have a life span ranging from 2 to 5 days, however locally produced cytokines such as IL-5, IL-3, GM-CSF, IL-33, and interferon-γ may increase this survival time (up to 12 days)[3][8][17]. Eosinophils are predominantly trafficked to mucosal surfaces of the respiratory, lower genitourinary and gastrointestinal tracts where they reside within the lamina propria (excluding the oesophagus).
