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.
疱疹病毒通过抑制自然杀伤细胞受体(NKG2D)激活配体(如MICB)来破坏免疫细胞的激活。最近有研究表明,一种人类巨细胞病毒微小RNA可抑制MICB的表达。纳赫马尼等人(2009年)将这一发现扩展到另外两种人类疱疹病毒,证明了病毒微小RNA尽管在序列上没有保守性,但仍具有保守的功能作用。
