Article Synopsis
- The study highlights that pollen counts often include Urtica, a non-allergenic plant, leading to incomplete data on allergens in the atmosphere, especially concerning allergic reactions.
- The objective was to compare Urticaceae pollen counts with actual concentrations of allergenic proteins (Par j 1 and Par j 2) in two areas in Spain, using advanced sampling and quantification methods.
- Results showed varying pollen and allergen levels between locations and years, with a key finding that there was a weak correlation between Urticaceae pollen and allergen concentrations, suggesting a need to include allergen measurements in future aerobiological studies for more accurate allergy assessments.
Effects of air pollution on cup a 3 allergen in Cupressus arizonica pollen grains.
Ann Allergy Asthma Immunol
July 2008
Article Synopsis
- The Cupressaceae plant family, particularly Cupressus arizonica, produces allergenic pollen (Cup a 3) that contributes significantly to winter respiratory allergies, especially in polluted regions like North America and Mediterranean areas.
- This study utilized advanced microscopy techniques to analyze how air pollution affects the expression of Cup a 3 in cypress pollen from various pollution levels across Spain.
- Results indicated that Cup a 3 was more abundant in pollen from polluted areas, suggesting that these plants react to air pollution by increasing allergen production, which may heighten allergy risks for individuals.
Allergenic proteins in Urtica dioica, a member of the Urticaceae allergenic family.
Ann Allergy Asthma Immunol
September 2006
Background: Allergy to the pollen of flowering plant species significantly affects the health of people in many parts of the world. Pollens of related genera usually share common antigens and are often, but not always, cross-reactive. Several studies have shown that Parietaria pollen is one of the most common causes of pollinosis in the Mediterranean area, whereas Urtica has no allergenic significance.
View Article and Find Full Text PDFBackground: In patients with pollinosis, allergic symptoms are often correlated with the number of airborne pollen grains, although this correlation is not always close. The direct measurement of the concentration of aeroallergens has only recently been introduced and is an important advance in public health information systems.
Objective: To compare specific quantification of aeroallergens Ole e 1 and Par j 1-Par j 2 Olea and Urticaceae pollen counts.
Production profile of the major allergen Alt a 1 in Alternaria alternata cultures.
Ann Allergy Asthma Immunol
December 2004
Background: The fungus Alternaria is strongly associated with asthma, but the importance of fungal allergen products is frequently underestimated. The profile of allergen release from fungal material is poorly understood.
Objective: To investigate expression of the major allergen of Alternaria alternata, Alt a 1, during its growth in culture conditions for allergen extract production.
Zygophyllum fabago L. (Zygophyllaceae) can be found in the Middle East, in North Africa and in the arid zones of the Mediterranean region. It easily establishes itself in new regions, and is considered an invasive plant.
