Allergen immunotherapy (AIT) is considered the only disease-modifying treatment available at present for allergic disorders. Its main benefits include improvement of symptoms, decreased need for pharmacotherapy, prevention of new sensitizations and sustained effect after AIT completion. The key pillars of AIT-induced tolerance include a shift from Th2 to Th1 response, an increase of regulatory T and B cells, pro-inflammatory effector cell downregulation and IgE suppression, in addition to IgG4, IgA and IgD induction. AIT may also induce trained immunity, characterized by a durable decrease in group 2 of innate lymphoid cells (ILCs) and increased ILC1 and ILC3s. Understanding the immune mechanisms of AIT is essential for validating biomarkers for the prediction of AIT response and for achieving AIT success.

Objective: This cross-sectional study aimed to evaluate parents' knowledge, attitudes and practices (KAP) concerning the prevention and treatment of dust mite allergy in children.
Design: This cross-sectional study survey was conducted from September to December 2022 at Shengjing Hospital, Affiliated with China Medical University.
Participants: A total of 503 parents of children with dust mite allergies participated, with 253 parents having children undergoing desensitisation treatment and 250 parents whose children did not.

Purpose Of Review: There is an increasing awareness among clinicians that industrial and household food processing methods can increase or decrease the allergenicity of foods. Modification to allergen properties through processing can enable dietary liberations. Reduced allergenicity may also allow for lower risk immunotherapy approaches.

The purpose of this study was to compare the efficacy and safety of subcutaneous, sublingual, oral specific immunotherapy in patients who suffer from allergic conditions to pollen from trees, grasses and weeds, house dust mites and Alternaria alternata spores. A literature search was performed separately for each type of allergen and each administration route of the drug. As a result, it was found that all administration routes were quite effective.

Background: House dust mite (HDM) is the leading allergen for allergic rhinitis (AR). Although allergic sensitisation by inhaled allergens renders susceptible individuals prone to developing AR, the molecular mechanisms driving this process remain incompletely elucidated.
Objective: This study aimed to elucidate the molecular mechanisms underlying HDM-induced AR.

Climate change is significantly altering the dynamics of airborne allergens, affecting their seasonality, allergenicity, and geographic distribution, which correlates with increasing rates of allergic diseases. This study investigates aeroallergen sensitization among populations from Tenerife, Spain, and Lima, Peru-two regions with similar climates but distinct socio-economic conditions. Our findings reveal that Spanish individuals, particularly those with asthma, demonstrate higher sensitization levels to a broader range of allergens, especially mites, with 85% of participants reacting to at least one mite allergen.
