Amsterdam Rheumatology Center for AutoImmune Diseases

Update video's 2022

Most of our fellows are now well under way with their research, so we want to update the video's they presented in May 2021 describing their projects. Please keep an eye on LinkedIn and Twitter and here, to see the updates!

We start with a video from Marina Jimenez who started in 2022 on the project "Mesenchymal stromal cells as key orchestrators in RA" in the group of Dr. Lisa van Baarsen.

And we continue with an updated video from Ana Merino Vico, working in the group of Dr. Sander Tas on the B cell lineage in ANCA-associated vasculitis.

The next update is from Armando Olivieri, working in the group of Prof. Niek de Vries on Clonal isotyping of the B cell response in autoimmunity.

Aoife O'Byrne , working in the group of Dr. Lisa van Baarsen to study the molecular and cellular features of human lymph node T cells during the earliest phases of systemic autoimmunity presents her update in this video.
