Herpesvirus tegument and immediate early proteins are pioneers in the battle between viral infection and nuclear domain 10-related host defense.

The sophisticated anti-viral functions of nuclear domain 10 (ND10) are revealed by identifying the role of each component and the countermeasures applied by viruses. Several ND10 proteins suppress herpesviruses at initial and early phases of infection. Herpesviruses need to antagonize these anti-viral proteins to start a productive infection. In this review the recently identified similarities and differences among the strategies adopted by the three subfamilies of herpesviruses are discussed, highlighting that one of the significant purposes of incorporating tegument proteins into the viral particles might be to counteract ND10 proteins immediately after the viral genome enters the host nucleus. Once the infection progresses, a sufficient amount of immediate early proteins is expressed to disperse and hydrolyze ND10 proteins, accelerating the development of infection.
