Cupressus arizonica pollen: a new pollen involved in the lipid transfer protein syndrome?
J Investig Allergol Clin Immunol
February 2012
Background: Lipid transfer proteins (LTP) are responsible for systemic manifestations in food allergy. Their relationship with pollinosis is not clear. In our area, many patients allergic to multiple LTP-containing foods present pollinosis due to Cupressus arizonica.

- 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.

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.

Upon contact with stigmatic secretion or with the mucosa of sensitive individuals, pollen grains absorb water and release soluble low-molecular-weight proteins, these proteins enter in the secretory pathway in order to arrive at the cell surface. In this study we located allergenic proteins in mature and hydrated-activated pollen grains of Parietaria judaica L.
