Asthma and Atopic Dermatitis: A Review of Targeted Inhibition of Interleukin-4 and Interleukin-13 As Therapy for Atopic Disease

Abstract

Type 2 helper T cell (Th2)-mediated inflammation plays a critical role in the pathogenesis of allergic asthma and atopic dermatitis (AD). Recent research focusing on the suppression of the Th2 axis with targeted inhibitors in atopic disease is showing promising early results. In particular, the simultaneous blockage of interleukin (IL)-4 and IL-13 has successfully mitigated symptoms of allergic asthma and AD in preliminary clinical trials. Given the current therapeutic challenges of treating these chronic and severe diseases, this review brings to light new data demonstrating that agents targeting IL-4 and IL-13 are relatively safe and effective medications in blocking the inflammatory cascade responsible for allergic asthma and atopic dermatitis.
