Susceptibility to asthma and eczema from mucosal and epidermal expression of distinctive genes



The past several years have seen an increase in the rate at which genes that are associated with allergic asthma and eczema are discovered. This review examines genetic association, gene expression, and functional studies that have identified genes that are expressed in the epithelial cells of the skin and lung and are involved in the pathogenesis of allergic asthma and eczema. This includes the genes encoding thymic stromal lymphopoietin (TSLP) and suppressor of cytokine signaling (SOCS3) that are involved in the activation of T-helper 2 cells, the microbial pattern recognition receptors nucleotide-binding oligomerization domain (NOD) genes (CARD4 and CARD15), Toll-like receptors (TLR2 and TLR4), and filaggrin, a protein required for effective barrier defense of the skin. Therefore, the development of allergic disease involves both the adaptive and innate immune systems, and the expression of these genes in the skin and lungs suggests a link to environmental triggers at body surfaces.
