Abstract:
:Initially described as an RNA surveillance pathway, nonsense-mediated decay (NMD) is also recognized to function in the regulation of host gene expression. In this issue of Cell Host & Microbe, three studies describe NMD-mediated defense strategies of plants and mammalian cells in response to pathogen infection.
