Carbohydrate epitopes are capable of binding human IgE from allergic subjects and these epitopes play a role in the cross-reactivity between allergens from unrelated sources. A monoclonal antibody (5E6), specific for a carbohydrate epitope detectable on components of Cupressus arizonica pollen
BACKGROUND
A reduction of IgE immunoreactivity after periodate-treatment has been previously reported for various glycoprotein allergens.
OBJECTIVE
The aim of this study was to investigate the role of glycan moiety of a C. arizonica extract in the binding of patients' IgE and to identify the
BACKGROUND
Cypress pollinosis is an important cause of respiratory allergies. Recently, the Cupressus arizonica major allergen, Cup a1, has been cloned and expressed. The native counterpart of this allergen has been purified and characterized by our group. It has been suggested that sugar moieties
Carbohydrates are known as sources of immunological cross-reactivity of allergenic significance. In celery and in cypress pollen, the major allergens Api g 5 and Cup a 1 are recognised by antisera raised against anti-horseradish peroxidase and by patients' IgE which apparently bind carbohydrate
The objectives of the present study were: (1) to localise, at the subcellular level, the allergens in pollen of Cupressaceae species, using a monoclonal antibody (mAb 5E6) that is specific for carbohydrate epitopes of allergenic components of Cupressus arizonica pollen extract; (2) to determine
The common cypress (Cupressus sempervirens) (Cups) pollen represents the first cause of respiratory allergies in the Mediterranean basin. The aim of this study was to characterize a novel 14-kDa cypress pollen allergen (BP14) allowing a clear dissociation of IgE sensitization patterns among allergic
At stand level, carbon translocation in tree stems has to match canopy photosynthesis and carbohydrate requirements to sustain growth and the physiological activities of belowground sinks. This study applied the Hagen-Poiseuille equation to the pressure-flow hypothesis to estimate phloem carbon
Talaromyces cellulolyticus is a promising fungus for providing a cellulase preparation suitable for the hydrolysis of lignocellulosic material, although its mannan-degrading activities are insufficient. In the present study, three core mannanolytic enzymes, including glycosyl hydrolase family 5-7
BACKGROUND
The Cupressaceae are an important cause of pollinosis, particularly in Mediterranean countries. Cypress pollen allergenic extracts are difficult to produce since they have a low protein and a high carbohydrate content and consequently accurate standardization of these extracts is
BACKGROUND
Atopic Dermatitis (AD) represents a chronic skin disorder seriously affecting patients' QoL and is often associated with immunological imbalance, disorders of the skin barrier function and environmental factors OBJECTIVE: We extensively studied the proteomic IgE
BACKGROUND
Cypress pollen allergy is an important cause of rhinoconjunctivitis and asthma in Mediterranean countries. Cypress allergenic extracts are difficult to produce since they have low protein and high carbohydrate content, thus accurate standardization of them is essential to guarantee their
As IgE glyco-epitopes, also referred to as cross-reactive carbohydrate determinants (CCDs), can share significant structural homologies between different plants, they are prone to extensive cross-reactivity among allergen pollen extracts. Here, cypress pollen allergens, especially a
The family Cupressaceae is a relevant source of allergens that causes winter respiratory allergies. Cloning and sequencing the major antigen of Cupressus arizonica is important for a better diagnosis and treatment of sensitized patients. To obtain a full-length complementary DNA for Cup a 1, the
The dry powder of the plant aereal part; Cupressus macro-carpa (Cupressacea) was tested against Biomphalaria alexandrina. LC50 & LC90 values were 59.5 & 98.8 ppm, respec-tively. Exposure of B. alexandrina to sublethal concentrations (LC0, LC10 & LC25) of C. macrocarpa for three weeks signi-ficantly
Gas chromatography (GC) was successfully used for the first time to determine the components of natural sugar meals in individual mosquitoes and to determine whether carbohydrases are present in the crops of these insects. Crops of wild mosquitoes collected from a 2-ha cypress swamp north of
