| Outline of Final Research Achievements |
The significance of stratum corneum (SC) barrier has been strengthened in the pathogenesis of atopic dermatitis (AD). Many other SC constituents and proteases are also known to be involved in the barrier. Here, we sought to identify and quantify wide-ranging proteins by proteome analysis of SC samples obtained by using a noninvasive tape stripping technique. We categorized the representative substances into 5 groups: inflammation-associated substances, SC barrier constituents, SC barrier-related enzymes, antimicrobial peptides, and sweat-associated substances. Many substances were changed in their amounts in AD-SC compared with healthy control (HC) SC. For example, the amounts of GCDFP15 were significantly lower in AD than HC. The sweat samples from AD patients also had lower levels of GCDFP15 concentration. GCDFP15 in SC is a potential marker for dysregulated sweating in AD.
