Selective IL-2 delivery modulates CD8+ T cells in human HLH and ameliorates disease features in a murine model Primary hemophagocytic lymphohistiocytosis (HLH) is a severe inflammatory syndrome. In familial HLH, loss-of-function mutations in genes such as Prf1 disrupt perforin-dependent cytolysis, leading to s...

The main part of my PhD work is published!

We found that targeted IL-2 therapy, instead of worsening HLH, improves disease by driving CD8 T cells into an exhaustion-like state, an immune brake we can harness to control inflammation, challenging the view that IL-2 only boosts CD8 T cell activity.

Nobel committee unable to reach prize winner who is ‘living his best life’ hiking off grid Fred Ramsdell was among those honoured with a 2025 Nobel Prize in Medicine but might not know because he is somewhere in Idaho and uncontactable The Nobel committee has been unable to reach a winner of this year’s prize for medicine who is “living his best life” on an “off the grid” hiking foray. Fred Ramsdell shared Monday’s prestigious prize with Mary Brunkow of Seattle, Washington and Shimon Sakaguchi of Osaka University in Japan for their discoveries related to the functioning of the immune system.

A split-site E3 ligase mechanism enables ZNFX1 to ubiquitinate and cluster single-stranded RNA into ubiquitin-coated nucleoprotein particles Grabarczyk et al. show the structure and mechanism of a non-canonical ubiquitin ligase, which is activated through nucleic-acid-induced oligomerization and is critical for cell survival during immune ...

Happy to share our work on the structure and function of the unusual E3 ligase ZNFX1 @cp-cell.bsky.social. It uses a nucleic acid-activated transthiolation mechanism, ubiquitinating and clustering RNA to protect cells in an immune response. @clausenlab.bsky.social

These are the most challenging times for early-career scientists and engineers.

My team is doing its bit to help by maintaining and even expanding our database of funding opportunities for early-career researchers.

We found 437 of them.
