How many gene transcripts do you actually need to diagnose rejection phenotypes after kidney transplantation?
In our latest study in @KIReports, we found that the answer is surprisingly low!

Evolving the Banff Classification for Kidney Allograft Rejection. This review paper by @_B_Chauveau et al. reports that innovations are reshaping rejection diagnostics! #Transplantation #KidneyTransplant #Transplantation #TXPforAll tinyurl.com/zh6m6wh6

We now have a mass spectrometry test available for membranous nephropathy (MN) antigens.
Started in 2017 with no lab/funding (& still no lab/major funding)-one at a time-we were able to discover majority of MN antigens.
It was an idea that worked out.

Kidney-transplant microvascular inflammation has a varied clinical presentation. This study of more than 16,000 biopsy specimens supports the recognition of additional rejection phenotypes to standardize diagnostics. nej.md/4hiFoyJ

Our study on post-transplant TMA is out! TMA is mostly driven by AMR and CNI toxicity but often due to multiple factors, with higher rates of complement pathogenic variants, and associated with a poor prognosis.

A nice collaborative work from the French Nephropathology Group!

Finally, the Banff 2022 Meeting Report and Workplan manuscripts underwent standard peer review by @amjtransplant, before being accepted and published.
Importantly, it was decided that the Banff Meeting Report manuscript(s) are made Gold Open Access.

Any ideas what these interstitial dots are?
Immune cells do not seem to bother about it; not the aspect of Russel bodies to me.

No immune deposits by IF but also present in the frozen sample. Any ideas? 🙏
