All-atom virus simulations.

Area of Science:

• Virology
• Computational Biology
• Biophysics

Background:

• Viral diseases pose a significant global health threat, necessitating novel vaccines and therapeutics.
• Experimental methods alone often struggle to provide high-resolution characterization of virus structure and dynamics.
• All-atom molecular dynamics (MD) simulations have emerged as a powerful tool to overcome these limitations.

Purpose of the Study:

• To review exemplary all-atom molecular dynamics simulation work on viruses.
• To highlight progress in simulating entire virions using computational approaches.

Main Methods:

• Comprehensive review of existing literature on all-atom MD simulations applied to viruses.
• Analysis of key studies demonstrating the utility of MD in understanding viral structural components and dynamics.
• Discussion of advancements and challenges in simulating complete viral particles.

Main Results:

• All-atom MD simulations have been successfully applied to study various aspects of viral structure and behavior.
• Significant progress has been made in simulating increasingly complex viral systems, including efforts towards whole virion simulations.
• These simulations provide atomic-level insights often inaccessible through experimental techniques alone.

Conclusions:

• All-atom molecular dynamics simulations are indispensable for advancing our understanding of viruses.
• Continued development in simulation methodologies will further enhance the study of viral structure, dynamics, and infection mechanisms.
• This computational approach is critical for the rational design of next-generation antiviral vaccines and therapeutics.
