Abstract
Atopic dermatitis (AD) is the most common inflammatory skin disease. It is characterized by a defective skin barrier and a Th2 dominated skin inflammation. The TNF family member a proliferation-inducing ligand (APRIL) and its receptors transmembrane activator and calcium modulator and cyclophilin ligand interactor (TACI) and B cell maturation antigen (BCMA) are expressed by immune cells and epithelial cells including keratinocytes. We demonstrate that APRIL expression is upregulated in the epidermis of skin lesions from patients with AD as well as in mouse skin undergoing allergic inflammation elicited by epicutaneous (EC) sensitization with the antigen ovalbumin. We show that APRIL from OVA sensitized mouse skin causes keratinocytes to upregulate the expression of IL-6, an inflammatory cytokine implicated in AD pathogenesis. These results suggest a role for APRIL in allergic skin inflammation and a potential role for APRIL blockade in treating AD.
