Summary
Recent advances in genetically modified pigs and immune response control have improved renal xenotransplantation survival to two years. Preclinical pig-to-primate models are crucial for further progress in this life-sustaining organ transplantation.
Area of Science:
- Organ transplantation
- Immunology
- Veterinary medicine
Background:
- Renal xenotransplantation, using animal organs in humans, faces challenges like immune rejection and lower survival rates compared to other organs.
- Preclinical pig-to-primate models have been instrumental in advancing the field.
- Historically, survival rates for renal xenografts have been limited, hindering clinical application.
Purpose of the Study:
- To review the recent progress in renal xenotransplantation.
- To highlight the role of preclinical models and genetic modifications in improving outcomes.
- To discuss the limitations and future directions for clinical translation.
Main Methods:
- Utilizing genetically modified porcine donors.
- Implementing strategies to control the anti-porcine immune response.
- Managing coagulation in xenotransplantation models.
- Employing pig-to-primate models for preclinical research.
Main Results:
- Survival rates of up to two years have been achieved in renal xenotransplantation.
- Genetically modified pigs and improved immune/coagulation control contribute to prolonged graft survival.
- Pig-to-primate models show promise but have limitations, such as differing antibody responses.
Conclusions:
- Significant progress has been made in renal xenotransplantation, extending survival times.
- Non-human primate models remain essential for future innovations and testing.
- While human applications are emerging, widespread success depends on continued research and refinement of techniques.
