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

Published date

August 25, 2023

Abstract


"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. We describe the neuroimmune interactions that underlie the various sensory and autonomic pathologies in type 2 inflammatory diseases and present recent advances in targeted treatment approaches to reduce type 2 inflammation and its associated symptoms in these diseases. Further research is needed to better understand the neuroimmune mechanisms that underlie chronic, sustained inflammation and its related sensory pathologies in diseases associated with type 2 inflammation."
