Neuroimmune interplay during type 2 inflammation: symptoms, mechanisms and therapeutic targets in atopic diseases

Type 2 inflammation is characterized by overexpression and heightened activity of type 2 cytokines, mediators and cells that drive neuroimmune activation and sensitization to previously sub-threshold stimuli. The consequences of altered neuroimmune activity differ with tissue type and disease and include: skin inflammation, sensitization to pruritogens, and itch amplification in atopic dermatitis and prurigo nodularis; airway inflammation/hyperresponsiveness, loss of expiratory volume, airflow obstruction and increased mucus production in asthma; loss of sense of smell in chronic rhinosinusitis with nasal polyps; and dysphagia in eosinophilic esophagitis.
