BACKGROUND: miRNAs are a class of noncoding RNA molecules that modulate gene expression after transcription. It is known that miRNAs are involved in various cellular processes of both normal and diseased skin. Recently, differential expressions of miRNAs have been reported and associated with several immunologic and inflammatory disorders, which indicate a common role in fundamental biologic processes. OBJECTIVE: To collect and review data from the literature on involvement of miRNA in inflammatory skin disorders. METHODS: A bibliographic search of scientific literature was carried out independently by two researchers in scientific data bases and search engines. The MeSH terms used were the following: "microRNAs" combined with "skin," "dermatitis," "urticaria," "eczema," "hypersensitivity." All research articles from inception until April 2016 were considered. RESULTS: A total of 11 research articles on the study of miRNAs in inflammatory skin disorders (atopic dermatitis, delayed-type hypersensitivity, eczema, toxic epidermal necrolysis) were identified. All the studies confirmed the main role of endogenous noncoding RNAs in diseases such as atopic dermatitis, allergic contact dermatitis, eczema, and toxic epidermal necrolysis. CONCLUSION: The miRNAs seem to influence regulatory mechanisms of inflammation in both inducing and contrasting acute and chronic skin inflammation. They also seem to be useful instruments in identifying and staging diseases such as dermatitis and other inflammatory skin diseases. Also, the potential application of miRNAs in genetic therapies demonstrated its efficacy on animal models.

Abstract

BACKGROUND: miRNAs are a class of noncoding RNA molecules that modulate gene expression after transcription. It is known that miRNAs are involved in various cellular processes of both normal and diseased skin. Recently, differential expressions of miRNAs have been reported and associated with several immunologic and inflammatory disorders, which indicate a common role in fundamental biologic processes. OBJECTIVE: To collect and review data from the literature on involvement of miRNA in inflammatory skin disorders. METHODS: A bibliographic search of scientific literature was carried out independently by two researchers in scientific data bases and search engines. The MeSH terms used were the following: "microRNAs" combined with "skin," "dermatitis," "urticaria," "eczema," "hypersensitivity." All research articles from inception until April 2016 were considered. RESULTS: A total of 11 research articles on the study of miRNAs in inflammatory skin disorders (atopic dermatitis, delayed-type hypersensitivity, eczema, toxic epidermal necrolysis) were identified. All the studies confirmed the main role of endogenous noncoding RNAs in diseases such as atopic dermatitis, allergic contact dermatitis, eczema, and toxic epidermal necrolysis. CONCLUSION: The miRNAs seem to influence regulatory mechanisms of inflammation in both inducing and contrasting acute and chronic skin inflammation. They also seem to be useful instruments in identifying and staging diseases such as dermatitis and other inflammatory skin diseases. Also, the potential application of miRNAs in genetic therapies demonstrated its efficacy on animal models.
