Immune Dysregulation in the Pathogenesis of Atopic Dermatitis

Atopic dermatitis is a multifactorial disease. Epidermal barrier impairment often plays the initial role in the initiation of the disease. Immune dysregulation of the innate and adaptive immunity plays a central role in the pathogenesis of atopic dermatitis. Alteration of the epidermal microbiome-host interaction serves a catalytic role in propagating this immune response. The understanding of this disease pathogenesis is important in generating treatment options, especially those such as biologic agents that can target a specific immune pathway.
