Abstract：
:Herpesviruses subvert immune cell activation by inhibiting NK cell receptor (NKG2D)-activating ligands such as MICB. A human cytomegalovirus microRNA was recently shown to repress MICB expression. Nachmani et al. (2009) extend this finding to two other human herpesviruses, providing evidence for a conserved functional role of viral microRNAs despite no sequence conservation among them.
