A 24-yeаr-оld wоmаn presents with а 5-year histоry of worsening seasonal runny nose, itchy eyes, and sneezing that manifests every spring. She has tried over-the-counter loratadine (Claritin®) and intranasal fluticasone (Flonase®) with minimal relief. Skin prick testing shows a 6-mm wheal in response to mixed grass pollen. Subcutaneous allergen immunotherapy with gradually increasing doses of grass pollen extract is initiated. After 2 years of treatment, she reports markedly decreased nasal congestion and ocular pruritus (itchy eyes) during the pollen season, and repeat skin testing shows smaller wheal-and-flare reactions to grass allergens compared with baseline. Which of the following immunologic changes most likely explains this patient’s clinical improvement?
