BACKGROUND
Asthma is an inflammatory condition characterized by airway hyperresponsiveness and chronic inflammation. The resolution of inflammation is an essential process to treat this condition. In this study we investigated the effect of Allium cepa L. extract (AcE) and quercetin (Qt) on cytokine
OBJECTIVE
To determine the IgE reactivity against recombinant protein Blo t 1 from the dust mite Blomia tropicalis (Bt) using serum from patients with positive skin test to this mite and to investigate the cross-reactivity between Bt and Dermatophagoides pteronyssinus.
BACKGROUND
Dust mites have an
BACKGROUND
House dust mite allergens have been shown to be a very important stimulus in the causation of asthma and triggers for the exacerbation of symptoms. Therefore, characterization of mite-derived allergens at the molecular level is an important step for the development of effective diagnostic
BACKGROUND
Tropomyosin belongs to a class of highly conserved proteins in invertebrates and vertebrates. The invertebrate tropomyosins are allergenic in man with high IgE cross-reactivity and have been therefore referred to as pan-allergens.
OBJECTIVE
This study aimed to clone and identify the IgE
Blomia tropicalis is an important mite species in many parts of the world and the most predominant mite species in tropical countries. The prevalence of sensitization to this species has probably been underestimated because commercial extracts are largely unavailable. Identification and
BACKGROUND
The complementary DNA (cDNA) encoding for Blo t 11, a 102 kD allergen from Blomia tropicalis (Bt) was isolated, expressed and characterized previously. This study aimed to isolate the native Blo t 11 allergen and compare its allergenicity with the recombinant forms.
METHODS
Native Blo t
BACKGROUND
The identification of immunodominant peptides containing the IgE and IgG epitopes on allergen molecules is an important step in understanding the interaction of the allergen with the immune system and, thus, essential for the development of effective immunotherapeutic and diagnostic
BACKGROUND
Blomia tropicalis is an important mite species in the tropics and subtropical regions of the world. It is well established that the allergen from this species of mite is one of the triggering factors for allergic asthma. The isolation and characterization of allergens in this mite species
Blo t 11, a dust-mite (Blomia tropicalis) paramyosin, is an allergen with significant IgE reactivity that has potential as a diagnostic/therapeutic reagent for house-dust-mite allergy. The present study describes the successful expression of Blo t 11 and its immunodominant peptide fD in insect cells
BACKGROUND
House dust mite allergens are the most important indoor allergens associated with asthma and rhinitis in Singapore and the tropics. Recent data to suggest that besides the Dermatophagoides spp., the domestic mite Blomia tropicalis (Bt) is also an important source of allergens in these
Blomia tropicalis (Bt) and Dermatophagoides pteronyssinus (Dp) are the predominant domestic mites species in Singapore and Taiwan. This study aims to characterize and compare the mite sensitization profiles in both countries. Skin prick tests were performed on 203 Singaporeans with Dp and Bt crude
Oral tolerance is an important approach in allergic diseases and murine model can provide useful information to improve its understanding and therapeutic measures. To address the influence of non-related allergen sensitization in immunized mice with the mite Blomia tropicalis (Bt) or ovalbumin (OVA)
Allergic asthma, rhinitis, rhinoconjunctivitis and atopic dermatitis are the most common allergic disorders that are caused by the house dust mite (HDM). Beside pyroglyphid mites, the clinical importance of non-pyroglyphid mites has also been increasingly recognized in the recent years. Blomia
The Blomia tropicalis dust mite is prevalent in tropical and subtropical regions of the world. Although it is a leading cause of asthma, little is known how it induces allergy. Using a novel murine asthma model induced by intranasal exposure to B. tropicalis, we observed that a single intranasal
BACKGROUND
Blomia tropicalis is a mite that belongs to the superfamily of Glycyphagidae. Initially described as a storage mite, it is now considered as a house dust mite of tropical and sub-tropical areas.
BACKGROUND
Sensitization to this mite is very common in South America and Southeast Asia.
