title: Chromatin at the intersection of viral infection and DNA damage.
abstract: During infection, viruses cause global disruption to nuclear architecture in their attempt to take over the cell. In turn, the host responds with various defenses, which include chromatin-mediated silencing of the viral genome and activation of DNA damage signaling pathways. Dynamic exchanges at chromatin, and specific post-translational modifications on histones have recently emerged as master controllers of DNA damage signaling and repair. Studying viral control of chromatin modifications is identifying histones as important players in the battle between host and virus for control of cell cycle and gene expression. These studies are revealing new complexities of the virus-host interaction, uncovering the potential of chromatin as an anti-viral defense mechanism, and also providing unique insights into the role of chromatin in DNA repair.
