Abstract
MicroRNAs (miRs) are short single-stranded non-coding RNAs that regulate protein synthesis by translational repression or degradation by targeting mRNAs at the post-transcriptional level. Highly conserved across species, they are known to regulate many genes in critical pathways during the lifetime. Any dysregulation at the cellular level, but also in the entire organism, is therefore harmful. The brain is a privileged organ in many ways, and interestingly, the majority of miRs are expressed in the brain. We describe miRs biogenesis in this chapter and focus on the role of cell-specific miRs in normal brain physiology and homeostasis.
