Area of Science:

  • Xenotransplantation research
  • Virology
  • Public Health

Background:

  • Xenotransplantation is a promising solution for organ failure but risks transmitting porcine viruses.
  • A recent pig heart transplant resulted in porcine herpesvirus transmission, underscoring screening needs.

Purpose of the Study:

  • To develop and present comprehensive viral screening protocols for donor pigs.
  • To ensure the safety of xenotransplantation by identifying potentially pathogenic porcine viruses.

Main Methods:

  • Established sensitive and specific PCR-based techniques for detecting multiple porcine viruses (PCMV/PRV, HEV, PCV1-4, PLHV-1-3, PERVs, PPV, TTSuV1,2, APPV, SARS-CoV-2).
  • Developed immunological assays to detect antibodies for PCMV/PRV, HEV, PLHVs, and PERVs.

Main Results:

  • A complete set of updated protocols for comprehensive viral screening in donor pigs was established.
  • Methods cover a wide range of viruses relevant to xenotransplantation safety.

Conclusions:

  • Specialized virological diagnostic units are crucial for screening viruses relevant to xenotransplantation.
  • Effective implementation of these protocols is essential for advancing safe xenotransplantation practices.
