Summary

This review details the molecular mechanisms of retroviral assembly, focusing on how structural proteins form infectious virions. We examine the process of virion budding and release from infected cells, particularly for human immunodeficiency virus type 1.

Area of Science:

  • Molecular biology
  • Virology
  • Cell biology

Background:

  • Retroviral assembly is a complex process involving structural protein synthesis and targeting.
  • Virion formation and release are critical for retroviral propagation and infection.

Purpose of the Study:

  • To review the molecular mechanisms governing retroviral virion assembly.
  • To focus on the assembly process of human immunodeficiency virus type 1 (HIV-1).

Main Methods:

  • Literature review of retroviral assembly mechanisms.
  • Focus on molecular details of virion formation and release.

Main Results:

  • Structural proteins are translated and targeted to the plasma membrane.
  • Nascent virions induce plasma membrane budding, leading to particle release.

Conclusions:

  • Understanding retroviral assembly is key to developing antiviral strategies.
  • HIV-1 assembly provides a model for lentivirus replication.
