Comprehensive phage display viral antibody profiling using VirScan: potential applications in chronic immune-mediated...

Area of Science:

• Immunology
• Virology
• Genomics

Background:

• Phage immunoprecipitation sequencing (PhIP-Seq) is a high-throughput serological platform utilizing programmable phage display.
• VirScan is a PhIP-Seq library covering peptides from all known human viruses, enabling broad assessment of past viral infections.

Purpose of the Study:

• To review the application of VirScan in immune-mediated diseases (IMDs).
• To highlight the role of viral exposures in IMD pathogenesis.
• To evaluate the potential of PhIP-Seq for precision medicine through integration with omics data.

Main Methods:

• Utilizing the VirScan PhIP-Seq library for comprehensive viral peptide profiling.
• Reviewing existing literature on PhIP-Seq applications in IMDs.
• Proposing integration strategies with other omics data.

Main Results:

• PhIP-Seq, particularly VirScan, is effective in quantifying diverse viral exposures.
• Identified associations between specific viral exposures and IMD development.
• Demonstrated potential for integrating viral serology with multi-omics data.

Conclusions:

• PhIP-Seq offers a powerful tool for studying viral infections in the context of immune-mediated diseases.
• VirScan facilitates the identification of etiological links between viral exposures and disease.
• Integration of PhIP-Seq with omics data holds promise for personalized medicine approaches.
