1/ We are celebrating the Novo Nordisk Prize Symposium: Inborn Errors of Immunity – a huge success yesterday at the @institutimagine.bsky.social in Paris featuring talks by 19 leading European researchers on human IEI

Delighted to be speaking at the Novo Nordisk Symposium: Inborn Errors of Immunity, celebrating Jean-Laurent Casanova (my PhD advisor) and his landmark contributions. Join us Sept 24 at Institut Imagine, Paris. Free to attend!

Exciting milestone for #HumanImmunity with the very first full issue of @jhumimmunity.org out now, including the #IUIS update on inborn errors of immunity + resources for clinicians. rupress.org/jhi/issue/1/1 #OpenAccess #IEI 👏👏👏

Delighted to share our manuscript highlighting the lessons learned from the clinical use of ex vivo T-lymphopoiesis assays to assist therapeutic decision-making btw #HCT and #thymus transplantation in patients without a molecular diagnosis after TREC-based newborn screening 👉 tinyurl.com/yzd8xe7p

1/ I was honored to accept the 2025 Novo Nordisk Prize from @novo-nordisk.bsky.social at today’s award ceremony in Copenhagen, Denmark. It was a wonderful day that included a tour of The BioInnovation Institute, lunch at @novo-nordisk.bsky.social, and an evening award celebration and dinner.

1/ Today we spotlight @sanchoshimizu.bsky.social, a postdoc in our Paris branch from 2006-12 and now Reader/Associate Professor at @imperialcollegeldn.bsky.social in the department of infectious diseases and head of both of a lab there and a satellite lab at the @crick.ac.uk

Rockefeller University Press launches new journal in partnership with scientists - News Open access, peer reviewed, and co-owned, the Journal of Human Immunity represents a new business model in scientific publishing.

Open access, peer reviewed, and co-owned, @jhumimmunity.org from @rupress.org represents a new business model in scientific publishing. Rockefeller's Jean-Laurent Casanova is the founding editor-in-chief.

The #IBEX Knowledge-Base is an exciting initiative promoting open science and collaboration for immunofluorescence multiplexed imaging! New to this wonderful community and excited for the research ahead! Find out more 👇🏾

Thank you to all collaborators and referring clinicians!

Journal of Human Immunity (JHI) @jhumimmunity.org is here! Read the inaugural editorial by @casanovalab.bsky.social outlining #JHI’s vision as the destination for groundbreaking research in human immunity and inborn errors of immunity. https://buff.ly/4hRGpOb

Our thymus, a critical source and trainer of T cells, involutes with aging. 2 new studies find a growth factor (FGF21) that delays involution (in mouse models) and may be a way to rejuvenate our immune system and promote healthy aging in the future.

For the full story 👉 doi.org/10.1084/jem....

Delighted & proud that this wonderful collection in @jem.org includes our study characterising dominant negative variants in ITPR3 in syndromic combined immunodeficiency patients due to calcium channel leakiness of the IP3 receptor, causing ER Ca2+ store depletion and impaired Ca2+ T cell dynamics.

A bird's-eye view of a former Auschwitz II-Birkenau camp showing a wide dirt pathway flanked by parallel rows of barbed-wire fences. Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations. Green grass contrasts with the somber history of the site, as the path leads toward a guard tower in the distance.

Auschwitz was at the end of a long process. It did not start from gas chambers.

This hatred was gradually developed by humans. From ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder.

Auschwitz took time.

Welcome to the future of #HumanImmunity research! @rupress.org and the International Alliance for Primary Immunodeficiency Societies (#IAPIDS) are launching the Journal of Human Immunity (JHI)! Stay tuned for groundbreaking, #OpenAccess research! 👉 https://buff.ly/4ajqm8W

What Happens When Some Cells Are More Dad Than Mom (and Vice Versa)? A new study shows that some of our cells favor genes of one parent or the other and can explain a longstanding mystery of why some people with disease-causing genes experience no symptoms.
