Out now in @Nature: our paper on multimodal precision diagnostics in clinical xenotransplantation. Hyperacute rejection is largely solved. The next challenge is the immune injury hiding below the surface, and we propose a framework to see it early. doi.org/10.1038/s41586-026-1…

New in @Nature: UMSOM researchers outline a roadmap for detecting immune rejection in pig-to-human organ transplants at the earliest, potentially reversible stage. 📰Read more: bit.ly/umsom-pig-transplant #Xenotransplantation

Congrats on the Nature paper. Shifting the focus from hyperacute rejection to the quieter immune injury underneath feels like the right next step for xeno. Which of your modalities tended to flag that hidden injury first, and how far ahead of clinical signs?

Looking forward to having more data to start running some AI models hehe…

Incredible work! Moving beyond hyperacute rejection to tackle hidden immune injury early will transform clinical decision-making in organ transplantation. Exceptional research! 👏

ブタ異種移植で超急性拒絶が抑制可能になった一方、従来診断では捉えにくい免疫性移植片障害が課題となっていることを踏まえ、早期検出、個別化免疫抑制、将来の遺伝子編集戦略につなげるマルチモーダル精密診断の枠組みを提案した総説がNature誌に発表されました。 nature.com/articles/s41586-0…

Thank you to Dr. @AndrewMCameron for joining the UMDOS as the 2026 Robert W. Buxton Lecture Keynote Speaker! His talk, entitled "Changing the Rules in Transplantation: Separating Science from Stigma", highlighted the miracle of liver transplant. #Surgery #Transplant #Maryland #Hopkins #GrandRounds
