MicroRNA-155: a Novel Armamentarium Against Inflammatory Diseases

An increasing number of diseases are being newly closely associated with inflammation, where microRNAs seem to play a critical role in the whole disease process from initiation to development. MicroRNAs are small non-coding RNAs that govern gene expression and modulation by means of mRNA degradation or translational repression. After several profound research studies, new correlations between microRNA-155 and inflammation-related diseases are strongly emerging. Hence, we review in this paper the possible molecular mechanisms of microRNA-155 in inflammatory disorders. Furthermore, we also consider the feasibility of targeting it as a bright alternative to improve the early diagnose statistics and treatments in those diseases. MicroRNA-155 features a novel breakthrough in fine-tuning inflammatory responses and, thereby, in treating a wide spectrum of diseases with inflammation as a common denominator.
