The hammock: a reservoir of allergens
(Faculdade de Medicina / USP, 2011)
INTRODUCTION: Asthma affects approximately 10% of the world's population. Sensitization to allergens is an important risk factor, and exposure to allergens is associated with disease severity. METHODS: We performed skin ...
Facing Hymenoptera venom allergy: from natural to recombinant allergens
(2015)
Along with food and drug allergic reactions, a Hymenoptera insect Sting (Apoidea, Vespidae, Formicidae) is one of the most common causes of anaphylaxis worldwide. Diagnoses of Hymenoptera venom allergy (HVA) and specific ...
Three-Dimensional Modelling of Honeybee Venom Allergenic Proteases: Relation to Allergenicity
(Verlag Z Naturforsch, 2011-05-01)
Api SI and Api SIT are serine proteases of the honeybee venom containing allergenic determinants. Each protease consists of two structural modules: an N-terminal CUB (Api SI) or a clip domain (Api SII) and a C-terminal ...
Allergenic extracts from Metarhizium anisopliae: Obtainment and characterization
(Hogrefe & Huber Publishers, 2005-01-01)
Metarhizium anisopliae is used as a biopesticide for insects that damage agricultural plantations like sugar cane and forage plants. In a previous study the sensitization to this fungus of asthmatic patients coming from ...
Using Proteomic Strategies for Sequencing and Post-Translational Modifications Assignment of Antigen-5, a Major Allergen from the Venom of the Social Wasp Polybia paulista
(Amer Chemical Soc, 2014-02-01)
Antigen-5 is one of the major allergens identified in wasp venoms, and despite the fact that its biological function is still unknown, many studies have demonstrated its allergenicity. In this study, the biochemical and ...
Reactivity of IgE to the allergen hyaluronidase from Polybia paulista (Hymenoptera, Vespidae) venom
(Elsevier B.V., 2014-05-01)
To date, there are no allergenic extracts or components available in Brazil to diagnosis and treatment of patients with venom allergy from social wasp (Vespidae Family; Polistinae Subfamily) despite of the great number of ...
Eosinophils in bronchial mucosa of asthmatics after allergen challenge: effect of anti-IgE treatment
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Anti-IgE, omalizumab, inhibits the allergen response in patients with asthma. This has not been directly related to changes in inflammatory conditions. We hypothesized that anti-IgE exerts its effects by reducing airway ...
Balance between early life tolerance and sensitization in allergy: dependence on the timing and intensity of prenatal and postnatal allergen exposure of the mother
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
P>Allergens can be maternally transferred to the fetus or neonate, though it is uncertain how this initial allergen exposure may impact the development of allergy responses. To evaluate the roles of timing and level of ...
