According to Thommen's postulates, what are the five requirements for an aeroallergen?

The selection of this answer is based on Thommen's postulates, which outline the necessary characteristics of aeroallergens. For an aeroallergen to be significant in causing allergic reactions, it must possess several key attributes:

1. Allergenic: It must be capable of eliciting an allergic response in sensitized individuals.

2. Buoyant: The allergen needs to be able to remain suspended in the air, allowing it to be inhaled and reach the respiratory tract where sensitization can occur.

3. Anemophilous: This means that the pollen or allergen must be dispersed by wind. Wind-pollinated plants produce allergens that are more likely to become airborne and affect individuals far from the source.

4. Abundant: The allergen should be present in sufficient quantities to have a significant impact on the population's sensitization and allergy prevalence.

5. Produced by a widely available plant: This ensures that the allergen is not only prevalent but also accessible in various environments where people are exposed.

These criteria highlight the multifactorial nature of aeroallergenicity, demonstrating the importance of environmental factors and biological characteristics in the development of allergic diseases. The combination of these attributes makes certain
