miRNA-mediated targeting of human cytomegalovirus reveals biological host and viral targets of IE2
A one-step recombineering strategy that inserts hematopoietic-specific miR-142 target sites into the untranslated region of the human cytomegalovirus IE2 transcript permits virus rescue in fibroblasts while silencing IE2 selectively in myeloid cells, revealing that IE2 loss raises rather than abolishes replication in macrophages.
