: Sensitization through inflamed skin can lead to early-onset food allergies.

: Often the first sign in infancy, caused by skin barrier defects (e.g., filaggrin mutations) that allow for epicutaneous allergen sensitization. : Sensitization through inflamed skin can lead to

: Systemic immune priming eventually leads to upper and lower airway inflammation. 3. Key Management Strategies While there is currently no cure, management focuses

: Antigen-presenting cells perceive allergens (like pollen or dust mites) as danger signals, activating TH2 or ILC2 cells. While there is currently no cure

The core of atopy is a Type I hypersensitivity reaction driven by a Type 2 immune response.

While there is currently no cure, management focuses on controlling inflammation and restoring barrier function. Atopy - StatPearls - NCBI Bookshelf - NIH

: These cells produce cytokines (IL-4, IL-13) that trigger B cells to differentiate into plasma cells producing allergen-specific IgE.
