Ara h 2 is a major peanut allergen that belongs to the 2S albumin family, known for its high allergenic potency in individuals with peanut allergies. Structurally, Ara h 2 is a small, stable protein resistant to heat and digestive enzymes, facilitating its persistence in the gastrointestinal tract upon ingestion. This stability enhances its immunogenicity and ability to elicit strong IgE-mediated allergic responses. Ara h 2 contains specific IgE-binding epitopes that are recognized by the immune system, making it central to the allergic reaction in sensitive individuals. The identification and characterization of Ara h 2 have been pivotal in understanding peanut allergy mechanisms, including efforts to develop diagnostic assays, immunotherapy treatments, and hypoallergenic peanut varieties. Studies have focused on mapping its epitopes, analyzing its cross-reactivity with other allergens, and leveraging its properties for therapeutic interventions. Its prominence as a peanut allergen underscores the importance of Ara h 2 in allergen research, aiming to reduce the burden of peanut allergies through targeted strategies.
