Area of Science:

  • Pulmonology
  • Virology
  • Pathology

Background:

  • Studying respiratory viruses requires physiologically relevant and scalable experimental systems.
  • Existing models like cell lines lack lung complexity, while animal models are costly and low-throughput.
  • There is a need for improved experimental platforms to study respiratory virus infection mechanisms.

Purpose of the Study:

  • To develop and validate a rapid and scalable precision-cut lung slice (PCLS) platform for respiratory virus research.
  • To assess the utility of PCLS in modeling influenza A virus replication, pathology, and immune responses.
  • To establish PCLS as a versatile tool for studying respiratory pathogens.

Main Methods:

  • Developed a workflow for generating infection-ready precision-cut lung slices (PCLS) within 24 hours.
  • Maintained tissue viability of PCLS over extended culture periods.
  • Utilized influenza A virus to infect PCLS and analyze viral replication, pathology, and immune cell responses.

Main Results:

  • The PCLS platform supports robust influenza A virus replication.
  • PCLS recapitulated key infection-associated lung pathology.
  • Localized immune cell responses within the respiratory epithelium were observed in infected PCLS.

Conclusions:

  • Precision-cut lung slices (PCLS) offer a scalable and physiologically relevant model for respiratory virus research.
  • PCLS overcome limitations of traditional cell lines and animal models.
  • This platform is valuable for studying influenza virus and other respiratory pathogens.
