On the other hand, a protocol developed by Eum and collaborators [26], using OVA, showed that shortening the duration of the allergic protocol did not affect the immunopathological features of the experimental disease, when it was compared with classical protocols [24]. Initially described as a storage mite, it is now considered as a house dust mite of tropical and sub-tropical areas. A quantitative digital morphometric analysis was performed using the application program Metamorph 6.0 (Universal Images Corp. Downingtown, PA, USA). Effect of immunization with 10 μg per injection ofB. Accordingly, sensitization of A/J mice to BtE led to pulmonary inflammation with eosinophil infiltrate and to total IgE increase, while OVA sensitization produced low eosinophil and IL-4 responses in this mouse strain.

Blomia tropicalis, a Storage mite, was earlier found predominantly in agricultural environments but is now being recognised as an important contributor to the allergen … Two key mechanisms for mucus production have been identified: one activated by engagement of epidermal growth factor receptor ligands (EGFR) and the other dependent on IL-13 and STAT6 signaling [29–31]. Eosinophil numbers increased in the BALF of all sensitized mouse strains, in relation to their saline control (Figure 1B; p < 0.05 for BALB/c and p < 0.001 for A/J, CBA/J and C57Bl/6; Tukey's test). **p < 0.01, ***p < 0.001, ANOVA.

Total IgE was detected using anti-mouse IgE-coated microtitre plates and biotin-conjugated anti-mouse IgE (UNLB Southern Biotechnology Associates, Inc., Birmingham, AL, USA), in conjunction with streptavidin-horseradish peroxidase, H2O2 and orthophenylenodiamine. After the observation that A/J was the best mouse strain for BtE-induced asthma, we immunized these mice with a low-dose (10 μg per injection) of BtE instead of the 100 μg dose per injection used in the previous experiments. As a global leader in allergy and autoimmune disease diagnostics, we are committed to providing accurate, clinically relevant testing solutions to aid in the proper disease diagnosis and patient management. Lipids from the lysate were extracted and discarded by five or six ether extractions. The described short-term model of BtE-induced allergic lung disease is reproducible in different syngeneic mouse strains, and mice of the A/J strain was the most responsive to it. Esta página foi editada pela última vez às 12h00min de 3 de dezembro de 2013. Total IgE was higher in BtE-sensitized animals (Figure 4A; p < 0001) and specific-IgE, IgG2a and IgG1 antibodies were higher in OVA-sensitized group (Figure 4B-D; p < 0.05, Tukey's test). Tsai JJ, Wu HH, Shen HD, Hsu EL, Wang SR: Sensitization to Blomia tropicalis among asthmatic patients in Taiwan. (A) Total leukocyte numbers in the bronchoalveolar lavage fluid (BALF). In addition, it was shown that OVA and BtE induce quantitatively different immune responses in A/J mice and that the experimental model can be set up with low amounts of BtE. Google Scholar.

Exposure to house dust mite allergens is recognized as the most important risk factor for the development of allergic diseases [1–3]. (C) Level of eosinophil peroxidase (EPO) activity in BALF. MR contributed in planning the experiments and reviewing the manuscript. We also concluded that a murine experimental model of respiratory allergy that uses BtE as allergen differs quantitatively in immunological and pathological parameters when compared with the classical experimental model that uses OVA as allergen.

Olívia Flores, Candeias, Vitória da Conquista, Bahia, CEP 4503100, Brazil, Departamento de Imunologia, Instituto de Ciências Biomédicas, Universidade de São Paulo; Av. There is evidence that allergens from B. tropicalis are distinct from, and bear only low to moderate cross-reactivity to allergens from Dermatophagoides sp. The production of IL-4 in BtE-sensitized and challenged mice was higher in A/J when compared with the other studied mouse strains (Tukey's test, p < 0.05; Figure 1E); it was followed by the production in CBA/J mice (p < 0.01, Tukey's test).

(F and G) representative lung sections stained with hematoxylin and eosin of a saline-injected animal (F) and a Bt-sensitized animal (G). Dust mite proteins, such as Blo t 11, a paramyosin from B. tropicalis that is homologue to a helminth molecule, is responsible for the cross-reactivity found between helminths and dust-mite species [33], and may be leading to the non-specific IgE stimulation in BtE-sensitized mice found in this and in the above mentioned work. Notably, mice sensitized with BtE produced higher amounts of total IgE than those sensitized with OVA, in amounts similar to those observed with immunization with helminth antigens [32]. The authors declare that they have no competing interests. IFN-γ and IL-4, IL-10 and IL-13 concentration measurements were assayed in commercial ELISA kits according to manufacturer's instructions (Pharmingen, St. Diego, CA, USA).

Blomia tropicalis, a Storage mite, was earlier found predominantly in agricultural environments but is now being recognised as an important contributor to the allergen content in house dust in indoor urban dwellings. Four different batches of BtE were used in different experiments. Differences in allergenicity between D. pteronyssinus and B. tropicalis antigens have also being reported in experimental models of asthma [14]. Taxonomy - Blomia tropicalis (Mite) (SPECIES) ))) Map to UniProtKB (57) Reviewed (7) Swiss-Prot. Finally, they had intense AHR. This study included the comparison of the allergic responses elicited by BtE with those elicited by ovalbumin in mice of the strain that responded better to BtE sensitization. Storage mites are a possible cause of allergic disorders and mostly present among agriculture population. Cheong N, Siew CS, Ramos JDA, Kuo IC, Prasanna K, Lee BW, Chua KY. The allergenity of B. tropicalis antigens to mice has been demonstrated before [14–16], although without a detailed investigation using different strains of mice and different doses of antigen. VMGS, TM and PRSO helped in the experiments on different mouse strains. P > 0.05 is not represented. The normality of the data was determined using the Komogorov-Smirnov test.

It is an in vitro quantitative assay that is intended to be used in conjunction with other clinical information to aid in the diagnosis of allergic diseases. The cell pellets were resuspended in PBS and lysed by three successive freezing and/thawing procedures, and then assayed for peroxidase activity in 96-well microassay plates, in duplicates, using 6.6 mM H2O2 and 1.5 mM orthophenylenodiamine (Merck, Whitehouse Station, NJ, USA). J Clin Immunol 2004,24(5):533–41. Rev Inst Med Trop Sao Paulo 2004,46(1):1–8. We sought to compare allergen inflammatory pulmonary response in previously sensitized mice orally administered with dust mites Blomia tropicalis (Bt) or Dermatophagoides pteronyssinus (Dp). tropicalisextract (Bt E) on the development of experimental respiratory allergy in A/J mice. It responded to immunization with the highest numbers of leukocytes in the BALF, consisting mainly of eosinophils, and had high levels of EPO activity in the BALF. Blomia tropicalis (d201) IgE - This allergen-specific IgE antibody test quantifies an individual’s IgE response to Blomia tropicalis. Eosinophils were the main cellular type, followed by neutrophils, found in the BALF of mice of the BtE-sensitized group, and macrophages were found in larger numbers in the saline control group (Figure 5B; p < 0.001 for differences in eosinophil counts between BtE-sensitized and control group; Student's t test). (C) OVA-sensitized group. The washings were carried out until no food residues could be seen under microscopy. The Blomia tropicalis storage mite belongs to the Glycyphagidae family. A familia Sarcoptidae inclúe animais parasitos como a carracha. The circunference area of the bronchi in the PAS-stained area was electronically measured and the mucus index was determined by the following formula: Mucus index = (PAS-stained area/bronquial cross-section area) × 100. (D) Bt-sensitized group. It may also infest stored food. tropicalis IgE antibodies. A significantly larger number of cells was found in the BALF of the mice sensitized with low-dose of BtE than in the BALF of the saline control group (Figure 5A; p < 0.01; Student's t test). LPC participated in planning the experiments and reviewing the manuscript. The effect of sensitization and challenge with 10 μg of BtE per injection on lung histology is seen in Figures 5F and 5G. Hales BJ, Shen HD, Thomas WR. Respiratory allergy to Blomia tropicalis: Immune response in four syngeneic mouse strains and assessment of a low allergen-dose, short-term experimental model. These findings justify studies on species-specific diagnosis and immunotherapy for B. tropicalis allergy in regions where this species occurs alone or concomitantly with D. pteronyssinus. BtE-immunized mice of the most responsive strain (A/J strain) were then assessed for the presence of intra-bronchial mucous, airway hyperresponsiveness (AHR) to methacholine challenge and inflammatory cell infiltration in lung tissue.

Data from A, B, and C are representative of three experiments, and from D of two experiments. For instance, antibodies from allergic patients against the main B. tropicalis allergens (proteins of 14.3 and 27.3 kDa) do not inhibit the binding of anti-D. pteronyssinus antibodies to D. pteronyssinus antigens [4, 9, 11]. Their body parts and fecal excreta are initially 10 to 50 mm in diameter but break down into smaller fragments that become airborne when dust is disturbed. Blomia tropicalis is significantly present in (sub)tropical geographic regions worldwide. 072405/Z/03/Z). Experimental data indicate that inbred mouse strains differ in their ability to mount an allergen-induced asthmatic response [17, 18]. (C) Anti-Bt or anti-OVA IgG2a antibodies. The tracheas of the dead mice were cannulated and the BALF collected in 0.5 mL of PBS containing 1% of bovine serum albumin (Sigma Chemical Co., St. Louis, MO, USA; PBS-BSA).

Groups of mice from different mouse strains were sensitized to BtE by subcutaneous injections of 100 μg or 10 μg of BtE adsorbed to 1.6 mg of alum [Al(OH)3] gel (Sigma Chemical Co., St. Louis, MO, USA) on days 0 and 7 and challenged intranasally with 10 μg of BtE in 50 μl of saline on days 8, 10, 12 and 14. Control groups received only alum and were challenged with saline or with BtE. Smith H: Animal models of asthma. Using a short time model, we showed that A/J mouse strain was the best responder in terms of providing an experimental model of respiratory allergy. Neuza M Alcântara-Neves. Dermatophagoides é um género de ácaros da família Pyroglyphidae presente na poeira intradomiciliar em todo o mundo. In order to verify differences among more than two mouse groups, the results were analyzed using the one-way ANOVA test and the Tukey's post test. This model may constitute a better approximation to a natural allergenic sensitization, in which allergic individuals tend to be exposed to low allergen doses, independently of the entry route, than the so far published experimental murine models, that use higher BtE doses [[14–16] and [35]].
