OMICS Integration Studies for New Insights on Atopic Dermatitis

The number of Atopic Dermatitis (AD) patients has increased with modernization and industrialization, and AD patients and their family members experience severe quality of life issues. It is generally recognized that a combination of environmental factors such as allergens and bacterial infections, as well as genetic factors, are the principal inducers of the multiple immunologic and inflammatory responses seen in AD patients. In the present review article, we focused on the following primary issues from the broad category of AD disease that have been reported in research articles, including those by the authors' own research groups: i) AD types: characteristics of extrinsic and intrinsic types; ii) current treatments of AD and clinical applications; iii) new insights from OMICS integration studies for detecting hub genes; iv) summary of AD pathogenesis and associated factors; and v) further speculation for AD studies. The topics in this review that we focused on are expected to contribute to the understanding of AD disease-related factors. Since the mechanism of AD disease has been shown to be complex, our results may provide new clues to aid understanding of AD from the aspect of laboratorial OMICS applications.
