High-content screening in infectious diseases.

Area of Science:

• Microbiology
• Drug Discovery
• Infectious Disease Research

Background:

• Automated microscopy and high-content screening (HCS) have advanced significantly over the past decade.
• HCS platforms now integrate automated pipetting, image acquisition, and data analysis for miniaturized assays.
• Initially used for genetic screens in host-pathogen interactions, HCS is increasingly applied in drug discovery.

Purpose of the Study:

• To highlight the evolution and application of high-content screening (HCS) in infectious disease research.
• To demonstrate HCS's utility in drug discovery for identifying novel antimicrobial compounds.
• To showcase HCS's role in profiling antiviral mechanisms and discovering host-specific inhibitors.

Main Methods:

• Utilizing high-content screening (HCS) platforms with integrated automated pipetting for miniaturized assays (384-well plates).
• Employing automated image acquisition, data storage, and analysis for high-throughput screening.
• Applying high-content analysis for intracellular tracking of viral particles to assess compound efficacy.

Main Results:

• HCS has been successfully adapted for drug discovery in both academic and industrial settings.
• High-content analysis allows for detailed profiling of antiviral mechanisms by tracking intracellular pathogens.
• Adaptation of HCS to bacteriology and parasitology has led to the discovery of novel host-specific inhibitors.

Conclusions:

• High-content screening (HCS) is a powerful tool for advancing infectious disease research and drug discovery.
• HCS facilitates the identification of new classes of antimicrobial agents, including host-specific inhibitors.
• The integration of automation in microscopy has revolutionized the study of host-pathogen interactions and therapeutic development.
