RT Journal Article SR Electronic T1 Human Cytomegalovirus Intrahost Evolution–A New Avenue for Understanding and Controlling Herpesvirus Infections JF bioRxiv FD Cold Spring Harbor Laboratory SP 009571 DO 10.1101/009571 A1 Nicholas Renzette A1 Laura Gibson A1 Jeffrey D. Jensen A1 Timothy F. Kowalik YR 2014 UL http://biorxiv.org/content/early/2014/09/30/009571.abstract AB Human cytomegalovirus (HCMV) is exquisitely adapted to the human host, and much research has focused on its evolution over long timescales spanning millennia. Here, we review recent data exploring the evolution of the virus on much shorter timescales, on the order of days or months. We describe the intrahost genetic diversity of the virus isolated from humans, and how this diversity contributes to HCMV spatiotemporal evolution. We propose mechanisms to explain the high levels of intrahost diversity and discuss how this new information may shed light on HCMV infection and pathogenesis.
