Grass Pollen Allergens

Grass pollen allergens are a diverse group of proteins found in grass pollen that trigger allergic reactions. Major allergen groups include Group 1 (β-expansins) and Group 5. These allergens induce IgE-mediated immune responses, leading to hay fever, asthma, and other allergic symptoms. Cross-reactivity with certain fruits and vegetables can cause oral allergy syndrome. Diagnosis involves skin prick testing or specific IgE blood tests. Management includes avoidance, pharmacotherapy, and immunotherapy.
