quercus macrocarpa pollen

Quercus macrocarpa pollen is an allergenic extract derived from the pollen of the Burr Oak tree. It is primarily utilized as a diagnostic tool in clinical allergy testing, such as skin prick tests or intradermal tests, to identify individuals with IgE-mediated hypersensitivity to oak pollen. As a biologic allergenic extract, it contains specific proteins that, when introduced to a sensitized individual, cross-link allergen-specific Immunoglobulin E (IgE) on the surface of mast cells and basophils. This interaction triggers the release of inflammatory mediators like histamine, resulting in a measurable wheal-and-flare reaction. Beyond its diagnostic use, similar extracts are also employed in allergen immunotherapy (desensitization) to treat allergic rhinitis, allergic conjunctivitis, and asthma by inducing immunological tolerance over time.
