Summary:
Background Allergy is characterized by allergen-specific IgE production. Molecular-based allergy diagnostic allows to define the precise sensitization profile. Bet v 1 is the major allergen of the PR-10 family. It has been reported that pan-allergens could affect the sensitization panel in adults. This study aimed to evaluate the impact of Bet v 1 sensitization on sensitization pattern in a large sample of children. Methods Serum IgE molecular components were assessed by ISAC method. Sera from 1,205 children, 708 males (58.76%) and 497 females (41.24%), median age 8.61 years (4.93 - 12.54 years) were analyzed. Results A total of 354 PR-10-positive subjects were detected out of 1,205 subjects. Bet v 1 positive children were significantly more frequently sensitized to other molecules belonging to PR-10 family and noteworthy also to other allergenic families than Bet v 1 negative children. Conclusions The present study demonstrates that Bet v 1 sensitization may significantly affect the sensitization pattern in children living in Genoa, a Mediterranean city located in a birch-free area.

NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
