The IL-4, IL-13 and IL-31 pathways in atopic dermatitis

Expert Rev Clin Immunol. 2021 Jun 9. doi: 10.1080/1744666X.2021.1940962. Online ahead of print.ABSTRACTINTRODUCTION: Atopic dermatitis (AD) is the most common inflammatory skin disease. It has a complex pathophysiology, with a combination of immune dysregulation and intrinsic barrier defects driving cutaneous inflammation and allergic symptomatology. The IL-4, IL-13, and IL-31 inflammatory pathways have been identified as hallmark features in the pathogenesis of the disease, contributing uniquely and synergistically to immune and barrier abnormalities as well as the key symptoms, such as pruritis. Novel therapeutics that target these pathways have been under development to find treatments for AD.AREAS COVERED: This review discusses the IL-4, IL-13, and IL-31 pathways in AD. We will also detail novel targeted therapeutics that have recently been or are currently in clinical trials for AD. A literature search was conducted by querying Scopus, Google Scholar, PubMed, and Clinicaltrials.gov up to January 2021 using combinations of the search terms "IL-4" "IL-13" "IL-31" "atopic dermatitis" "immune pathway" "biologics" "novel therapeutics" "JAK/STAT inhibitors."EXPERT OPINION: The complex pathophysiology of AD advocates for innovation. Novel minimally invasive sampling modalities such as tape stripping will allow for a broader characterization of the immunomechanisms behind AD pathophysiology. This will allow for the continued development of a personalized medicine approach to tre...
