Immune System (Allergen Exposure)

Molecular classification
Immune System Process
01

Overview

The immune system's response to allergen exposure is a complex process involving sensitization and effector phases. Sensitization involves IgE production and mast cell priming. Re-exposure triggers mast cell degranulation, releasing inflammatory mediators. Therapeutic strategies aim to block these mediators or induce tolerance through immunotherapy. Dysregulation of the immune system underlies all allergic diseases.
