Herpesvirus assembly involves two distinct budding events. This review details recent findings on the molecular mechanisms and viral proteins driving these crucial steps in herpesvirus morphogenesis.

Area of Science:

  • Virology
  • Cell Biology
  • Structural Biology

Background:

  • Herpesviruses are complex viral particles composed of over 30 virally encoded proteins.
  • Understanding the assembly process of herpesviruses is critical for developing antiviral strategies.

Purpose of the Study:

  • To review recent advances in understanding the two distinct herpesvirus budding events.
  • To elucidate the molecular mechanisms underlying herpesvirus morphogenesis.

Main Methods:

  • Review of recent scientific literature on herpesvirus assembly.
  • Analysis of viral protein functions in budding and envelopment.

Main Results:

  • Herpesvirus assembly involves two sequential budding events: nuclear egress and final envelopment.

  • The first budding event occurs at the inner nuclear membrane, releasing primary enveloped virions.
  • The second budding event involves Golgi-derived vesicles, incorporating tegument and envelope proteins.

    • Conclusions:

    • Herpesvirus morphogenesis is a complex, multi-step process requiring distinct budding events.
    • Recent research has shed light on the specific viral proteins and cellular compartments involved in these budding processes.
