Psoriasis is a chronic, immune-mediated inflammatory disorder characterized by hyperproliferation and abnormal differentiation of keratinocytes. Multiple factors including heredity, immunology and environment participate in its etiology and pathogenesis. MicroRNA and lncRNA are both non-coding RNA involved in many cellular processes and various diseases. They play an important regulatory role at epigenetic, transcriptional and post-transcriptional level. Recent studies have indicated that microRNA and lncRNA are correlated with the occurrence and development of psoriasis. In this review, the correlations between psoriasis and microRNA as well as lncRNA are summarized separately.
