Objective:

To synthesize recent advances in porcine transplantation science, focusing on xenotransplantation while examining pig-to-pig allotransplantation and human-to-pig chimerism for their relevance to immunological and physiological challenges.

Approach:

Key Findings:

• Advances in genome engineering and immunomodulation have been reported to enhance compatibility in porcine xenotransplantation.
• Multigene-edited pigs have been shown to reduce hyperacute and acute vascular rejection.
• Costimulation blockade targeting the CD40/CD154 pathway has been associated with prolonged graft survival in non-human primates.
• Improvements in organ preservation and molecular monitoring have been noted to enhance translational readiness.
• Porcine models provide platforms for studying tolerance induction and long-term graft biology.

Interpretation:

Despite significant advancements reported, challenges remain including delayed antibody-mediated rejection, coagulation dysregulation, and regulatory issues as noted in the literature.

Limitations:

• The review does not provide a formal systematic review count or PRISMA flow diagram.
• No formal PROSPERO registration was undertaken due to the narrative design.

Conclusion:

Porcine xenotransplantation has entered an early clinical era, with ongoing research focused on immune control and long-term safety.
