MicroRNAs (miRNAs) are a family of small non-coding RNAs (similar to 22 nucleotides) that fine-tune protein expression by either silencing mRNA translation or directly targeting gene transcripts for degradation. In the central nervous system (CNS), neuroinflammation plays a critical role in brain injury and neurodegeneration. Increasing evidence supports the involvement of miRNAs as key regulators of neuroinflammation. Altered expression or function of particular miRNAs has been identified in various CNS pathological conditions, including neuroinflammation, neurodegeneration, and autoimmune diseases. Several miRNAs have been shown to play a critical role in the microglia-mediated inflammatory response including miR-155 and miR-146a. In this review, we summarize recent advances in the field of miRNAs associated with CNS inflammation, including our studies of unique inflammatory pathways involving miR-155 and miR-146a. We discuss how specific miRNAs influence microglia activation states in response to inflammatory stimuli, and describe the potential of miRNAs as both biomarkers of inflammation and therapeutic tools for the modulation of microglia behavior.
