Abstract: | Two new studies describe functionally relevant interactions between microRNAs (miRNAs) and their targets in the immune system and the brain (Xiao et al., 2007; Karres et al., 2007). Furthermore, these studies illustrate the involvement of miRNAs in tuning the expression of target genes to physiologically relevant levels. |
