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. Background The dust mite Blomia tropicalis is an important source of aeroallergens in tropical areas. After each nebulization with methacholine, recordings were taken for 5 min. 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. 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). Ann Allergy Asthma Immunol 2003,90(6):664–8.

TB conducted the majority of the experiments involving different mouse strains, the OVA × BtE comparison experiments and wrote the first manuscript draft. Although the total cell counts in BALF were higher in sensitized A/J mice than in the other sensitized mouse strains, the differences were not statistically significant (p > 0.05, ANOVA test; Figure 1A). This finding corroborated the work of Takeda and collaborators [15], who found an increase of total IgE in BtE- and cholera toxin- sensitized mice. EGFR and STAT6 signaling were not investigated in the present study, but we found increased IL-13 levels, in relation to saline-treated controls, in BtE-sensitized A/J mice.

Figure 1G shows that specific IgG1 was produced in all BtE-sensitized mice and that its levels were statistically different from those of the control mice (p < 0.001 for BALB/C, C57Bl/6, and A/J mice, and p < 0.05 for CBA/J; Tukey's test). On the other hand, OVA sensitization led to higher mucus production, and serum levels of specific IgE, IgG1 and IgG2a than BtE sensitization. PubMed Central  Data from A, B, and C are representative of three experiments, and from D of two experiments. Allergol Immunopathol (Madr) 2006,34(1):23–6. (D) total serum IgE. BtE-sensitized animals had more total serum IgE as well as higher titers of anti-BtE IgE antibodies than the saline control group (Figure 5D and 5E; p < 0.05; Student's t test and Mann-Whitney's test, respectively). CAS  Groups of mice were sensitized subcutaneously with BtE co-adsorbed into alum on days 0 and 7, challenged intranasally with BtE on days 8, 10, 12 and 14 and studied 24 h later.

Cookies policy. In addition, groups of A/J mice were injected with 100 μg of OVA (Sigma Chemical Co., St. Louis, MO, USA) adsorbed to alum and challenged with 50 μL of saline containing 10 μg of OVA, as described above for the BtE. Animal models that mimic the immunological and pulmonary inflammation features observed in human asthma are important tools to dissect the basic cellular and molecular mechanisms involved in the initiation and control of allergy [12]. Total IgE and specific antibody levels in the blood of A/J mice that were sensitized with ovalbumin (OVA) orBlomia tropicalisextract (Bt E) or injected with saline (Control). (A) Total leukocyte numbers in the bronchoalveolar lavage fluid (BALF). Whitehead GS, Walker JK, Berman KG, Foster WM, Schwartz DA: Allergen-induced airway disease is mouse strain dependent. Mice of all strains had lung inflammatory-cell infiltration and increased levels of anti-BtE IgE antibodies, but these responses were significantly more intense in A/J mice than in CBA/J, BALB/c or C57BL/6J mice. This work was supported by the Brazilian Ministry of Science and Technology (RENORBIO programme and Conselho Nacional de Pesquisa e Desenvolvimento Tecnológico - CNPq), the Fundações de Amparo à Pesquisa dos Estados da Bahia e São Paulo (FAPESB and FAPESP), and the Wellcome Trust (Grant No. IgE antibody serum levels were estimated by PCA reaction, as described by Mota and Wong [23]. 由於成體長約0.2-0.3毫米且呈半透明,肉眼難辨識,一般要用10倍放大鏡才能確認;軀幹有紋狀外皮。 (C) Level of eosinophil peroxidase (EPO) activity in BALF. Sensitivities were >5 pg/mL for IL-4, >2 pg/mL for IL-10, >0.5 pg/mL for IL-13 and >0.03 ng/mL for INF-γ. Blomia tropicalis is significantly present in (sub)tropical geographic regions worldwide. Detectable dust mite allergen was found in the beds of about 84% of surveyed United States homes. … All used batches contained 30-40 ng of this allergen per μg of protein.

There is evidence that allergens from B. tropicalis are distinct from, and bear only low to moderate cross-reactivity to allergens from Dermatophagoides sp. This is accordance to Takeda and collaborators' observation that the intranasal instillation alone of BtE elicited an IgE antibody response only when the antigen was continuously administered for a period of over 24 weeks [15]. (D) Anti-B. The washings were carried out until no food residues could be seen under microscopy. Lab Anim Sci 1998,48(4):346–52. 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]. Int Arch Allergy Immunol 1997,113(1–3):102–4. Unreviewed (50) TrEMBL. The mites were lysed in 0.15 M phosphate-buffered saline, pH 7.4 (PBS), in a blender (Waring Commercial, Torrington, Connecticut, USA). It is described, herein, the development of a short-term protocol using B. tropicalis extract.

Differential cell counts were performed in light microscopy, according to standard morphologic criteria, by counting, in a blinded fashion, 100 cells in cytospin preparations stained with Rosenfeld's stain. However, in humans, most cases of asthma are due to aeroallergens, and OVA-induced asthma is far from being a common event. 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. 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. State of the art Sensitization to this mite is very common in South America and Southeast Asia. As a second objective of the present work, mice of the best-responder strain were immunized with relatively low doses of BtE aiming at obtaining a low allergen-dose, short term murine model of respiratory allergy to B. tropicalis that reproduced many immunological and pathological features of the human disease. Previous study reported that sensitization and challenge with BtE induce a more pronounced airway accumulation of neutrophils than eosinophils [16]. (D) Anti-Bt or anti-OVA IgG1 antibodies. The EPO activity was higher in the BALF of BtE-sensitized mice than in that of negative controls (Figure 5C; p < 0.01; Student's t test). Toxicol Pathol 2003,31(4):432–47. The BALF supernatants were stored at -70°C until used. (D) Degree of airway responsiveness, as shown by the area under the curve (AUC) of the response to methacholine × time. OVA-sensitized mice also showed increased total cell (p < 0.05; Figure 2A; Tukey's test) and eosinophil counts (p < 0.05; Figure 2B; Tukey's test) in the BALF than the corresponding control, saline-treated animals. The most common genus of mites found in house dust in north America and Europe is Dermatophagoides, of which there are two species, D. pteronyssinus and D. farinae. Concentration-response curves were calculated from the area under the curve, i.e. Clin Exp Allergy 2002, 32:602–611. *p < 0.05, **p < 0.01, ***p < 0.001. Eight to 10 week-old CBA/J, BALB/c, A/J and C57BL/6 male mice, and 3 to 4 month-old Wistar rats, were bred and maintained at the animal houses of the Gonçalo Moniz Research Center, Oswaldo Cruz Foundation, Salvador, Brazil, and of the Biomedical Sciences Institute, University of São Paulo, São Paulo, Brazil. 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. Tissues sections of 5-μm were then stained with periodic acid-Schiff (PAS) for the evaluation of mucus production. The first was to study the anti-B. LPC participated in planning the experiments and reviewing the manuscript. The data are representative of three independent experiments.
