PROTEINURIA AFTER PIG KIDNEY XENOTRANSPLANTATION: A POTENTIAL UNIFYING HYPOTHESIS LINKING MECHANICAL, INNATE, AND ADAPTIVE INJURY PATHWAYS.

Key takeaways

When gene-edited pig kidneys are put into monkeys, the new kidney often leaks a lot of protein into the urine, which is a sign of damage. This paper offers one theory to explain why, tying together physical pressure on the kidney and two kinds of immune attack. The authors point out that the few people who have received pig kidneys so far have not consistently shown this problem, so whether it matters in humans is still open. This is a hypothesis paper, not a study, so it has no new results.
