Seven colleagues standing side by side outdoors on a wooden deck with greenery and trees in the background.

From Kim Good-Jacobson and team, new data demonstrate a vital role for disruptor of telomeric silencing 1-like (DOT1L) during B-cell lymphopoiesis, marginal zone B-cell generation, and germinal center B-cell biology. Read this #EditorChoice article: https://ow.ly/Oa0750Yn56n

Emma Johnston was a visionary scientist, environmentalist and leader, with an abiding hope for humanity The University of Melbourne Vice-Chancellor, who has died aged 52, was driven by a deep love of science and a desire to safeguard the planet’s future.

Very sad news 😥

Conservation scientist and marine ecologist Emma Johnston has passed away 🧪

Why vaccines matter for children 10 facts about vaccines, child survival and global progress.

Smallpox killed 300 million people in the 20th century. Today? It's completely eradicated thanks to vaccines.

And polio cases are down 99% since 1988, with 20 million people walking today who would otherwise be paralysed.

ps Supp Fig 4 shows differential expression of epigenetic regulators in GC B cell subsets, + the unique & overlapping regions marked by H3K27me3, H4K4me3 and H3K79me3.

Understanding the dynamics & interplay of epigenetic regulators, their marks & GC B cell fate is something we are keenly exploring

Great to see this out!
Following on from our earlier work revealing DOT1L was essential for humoral responses, here we determine the importance of H3K79me2 at multiple stages of B cell biology

👏 to Liam for tenaciously driving this study
👏 to collabs incl @sjturn.bsky.social + those not on bsky

hey bluesky 👋 visa hurdles mean I’m looking for opportunities outside the US. I’m a computational biologist (bacterial + phage genomics, postdoc in Koonin’s group @ NIH). I am interested in teaming up on funding apps. reach out if this resonates!

👏🏼 congratulations!

What a great day; lots of fantastic discussions and a lovely location to boot!

Thank you for hosting me!

I've been developing a semantic search tool that covers not just bioRxiv and medRxiv, but the entire PubMed database. This means you can search across a massive collection of biomedical research using keywords, questions, hypotheses, or even full abstracts. Try it out: mssearch.xyz

Noted! Although that may have also happened with the characters in LM 😂

Ok bluesky - I want to finally get through one of these dust collectors during the Aussie summer… any recommendations of which to choose?

Closest I’ve gotten to W&P is reading Anna Karenina… and closest to I’ve gotten to LM is enduring the movie 🙃

Hi 👋🏼 The Vinuesa lab has arrived at BlueSky! Follow us if you want to talk about all the exciting science going on in autoimmunity, genetics, and anything B cell-related 🧬 🧪

I’ve tried to put together a starter pack of immunologists/scientists exploring B Cell Repertoires and Antibody Affinities.

Please feel free to share/join!

Congratulations Danika!!

Friends, it's fun to see the #immunology community continue to grow! I created a 4th Starter Pack to help folks find each other. If you're an immunologist and you don't see yourself on the lists, let me know 🧪

PD-1 regulates germinal center B cell survival and the formation and affinity of long-lived plasma cells - Nature Immunology PD-1 is commonly associated with inhibitory functions, yet it is highly expressed in follicular T cells. Shlomchik and colleagues find that PD-1 signaling in germinal centers is necessary for long-liv...

This study is a tour de force by Masato and Koji using rare samples from immunodeficient patients... and nicely complements our previous in vivo data (from my time in the Shlomchik lab) www.nature.com/articles/ni....

It's great to see this out in Immunity today!
Masato Ogishi, Koji Kitaoka, Jean-Laurent Casanova, Stuart Tangye on memory B cells in patients with PD-1 immunodeficiency

Also stoked to contribute unpublished recall response data from my postdoc a very long time ago 🙂

I must admit that this annotated Nature abstract remains a useful recipe for constructing a summary paragraph. I show it to my students every time we get started.
