Microscopic Analysis of Viral Infection

Area of Science:

• Virology
• Cell Biology
• Microscopy

Background:

• Live-cell imaging allows real-time monitoring of biological processes.
• Tracking viral infection dynamics is crucial for understanding disease progression.
• Existing methods may lack the resolution or multiplexing capabilities to fully capture infection events.

Purpose of the Study:

• To develop and present novel methods for visualizing viral infection dynamics using live-cell imaging.
• To enable real-time tracking of infection spread between cell populations.
• To visualize the transfer of individual virus particles (virions) between cells.

Main Methods:

• Engineering viruses to express fluorescent proteins for detection.
• Utilizing live-cell imaging techniques to monitor infection progression.
• Multiplexing viral tracking with physiological readouts of cell death.

Main Results:

• Demonstrated methods to track infection spreading from one cell population to another.
• Visualized the transfer of virions between individual cells.
• Correlated viral infection with cell death at single-cell resolution.

Conclusions:

• Fluorescent protein-expressing viruses combined with live-cell imaging provide powerful tools for studying viral infection.
• These methods offer high resolution for observing infection spread and virion transfer.
• The approach allows for detailed correlation of viral infection with cellular responses like cell death.
