Allergens of chrysanthemum pollen

Area of Science:

• Immunology
• Allergology
• Plant Science

Background:

• Pollinosis, or hay fever, affects millions globally.
• Plant pollens are common environmental allergens.
• Chrysanthemum and mugwort pollens are prevalent in certain regions.

Purpose of the Study:

• To identify and characterize allergens in Chrysanthemum pollen.
• To investigate the IgE-binding potential of Chrysanthemum pollen antigens.
• To explore potential cross-reactivity between Chrysanthemum and mugwort pollens.

Main Methods:

• Analysis of Chrysanthemum pollen extracts using crossed radioimmunoelectrophoresis (CRIE).
• Quantification of IgE-binding antigens via RAST-inhibition assays.
• Serological testing with sera from patients diagnosed with pollinosis.

Main Results:

• Identification of 38 distinct antigens in Chrysanthemum pollen extracts.
• Ten of these antigens demonstrated the ability to bind IgE antibodies from patient sera.
• RAST-inhibition experiments indicated an allergenic relationship between Chrysanthemum and mugwort pollens.

Conclusions:

• Chrysanthemum pollen possesses multiple allergens capable of eliciting allergic reactions.
• The identified allergens contribute to the understanding of chrysanthemum-induced pollinosis.
• Evidence suggests cross-reactivity, implying shared allergens between chrysanthemum and mugwort pollens.
