Presentation
The Paris Transplant Group (PTG) is developing a personalized approach for transplant medicine that integrates multidimensional information derived from standard of care (clinical and biological data, histology and immunology) together with novel information coming from cutting edge technologies in immunology, molecular biology, genetics and biomarkers.

The team includes several departments in kidney, heart, lung and liver transplantation, which are known as reference centres.

Kidney transplant
Our consortium includes leading national kidney transplant centers totalling more than 530 transplants each year

Heart transplant
The centers dedicated to heart transplant represent more than 80% of the overall national heart transplant activity (150 transplants each year).

Lung transplant
Our consortium includes leading transplant centers with more than 75 transplants each year.

Liver transplant
Our consortium of liver transplant centers, collaborating seamlessly, conducts over 400 liver transplant procedures annually.
PTG builts the largest comprehensive multi-organ cohort worldwide.

I see progress in figuring out how to guide immunosuppression toward individual patients' needs Amazing work here by Alex Loupy’s group illuminating how cell-free DNA reveals allograft inflammation, but a clinician needs to interpret in the clinical context. @AlexandreLoupy

Beyond standard of care monitoring for patients who are post-transplant, urinary chemokine CXCL9 demonstrated limited clinical utility, while CXCL10 provided no additional value. http://kidney.pub/JASN0742 #ASNJASN
