Sensitization to Peach tree pollen in a non-exposed population

Peach pollen has been identified as a relevant allergen in areas of high cultivar. At least two major proteins are recognized as primary sensitizers: Pru p 3 and another one that we identify as Pru p X. Because pollens share allergens among them and with plant-derived food allergens, our aim was to study Peach tree pollen sensitization in a non-exposed population (Madrid, Central-Spain).
