agrostis gigantea pollen allergen extract

Agrostis gigantea pollen allergen extract, also known as Redtop grass pollen extract, is a biological product used for the diagnosis and treatment of Type I hypersensitivity reactions (allergies) to this specific grass. [17, 11] It is administered for diagnostic purposes via skin prick or intradermal tests to confirm sensitivity. [3, 4] For therapeutic use, it is a key component of allergen immunotherapy, available as subcutaneous injections (allergy shots) or sublingual drops/tablets. [10, 16] The goal of immunotherapy is to induce immune tolerance by gradually exposing the body to increasing doses of the allergen. [16] This process modulates the immune response, shifting it from a pro-allergic Th2-dominant profile to a more tolerant state, characterized by the production of blocking IgG antibodies and a reduction in allergen-specific IgE levels, thereby alleviating symptoms of allergic rhinitis (hay fever), allergic conjunctivitis, and allergic asthma upon natural exposure.
