摘要：Approximately half of all atopic dermatitis (AD) patients subsequently develop asthma, particularly those with severe AD. This association, suggesting a role for AD as an entry point for subsequent allergic disease, is a phenomenon known as the "atopic march". While the underlying cause of the atopic march remains unknown, recent evidence suggests that epithelial cell (EC)-derived cytokines play a major role. We showed that mice exposed to antigen through the skin, in the presence of IL-33, developed antigen-specific airway inflammation when later challenged in the lung. IL-33 signaling was dispensable during effector/challenge phase. These data reveal critical roles for IL-33 in the "atopic march" and will offer a new therapeutic target in the treatment and prevention of allergic asthma.
