Very happy to share our new study defining the ontogeny of Thetis cells and the developmental cues that shape their early-life wave of differentiation. www.nature.com/articles/s41... Beautiful work led by @hhmi-science.bsky.social Gilliam Fellow Yoselin Paucar Iza and postdoc Tyler Park 1/

Online now: Stepwise epigenetic signal integration drives adaptive programming of cytotoxic lymphocytes

Stepwise epigenetic signal integration drives adaptive programming of cytotoxic lymphocytes
Adaptive programming in lymphocytes during infection depends on when—not just whether—they sense antigen and proinflammatory cytokines such as IL-12. Grassmann et al. reveal that AP-1/STAT4 cooperation links signal timing to lymphocyte fate, tuning CD8+ T cell responses and driving the decision between innate versus adaptive programs in NK cells.

Excited to share my paper published today in @cp-immunity.bsky.social! We find that when CTLs integrate antigen and cytokine signaling, the timing of these cues matters - shedding light on an old question: Why do NK cells sometimes behave like CD8+ T cells? www.sciencedirect.com/science/arti...

I didn't expect to be so sad learning that my favorite philosopher, Alasdair MacIntyre, has passed 💔. I hope I can explore lessons from his philosophy for STEM research more in the future, I made a first attempt in this book chapter: sciencedirect.com/science/arti...

So happy to see this story come together. Check it out! Kathleen Mills and many collaborators - GM-CSF–mediated epithelial-immune cell cross-talk orchestrates pulmonary immunity to Aspergillus fumigatus | Science Immunology www.science.org/doi/10.1126/...

GM-CSF–mediated epithelial-immune cell cross-talk orchestrates pulmonary immunity to Aspergillus fumigatus
During mold infection, epithelial-derived GM-CSF licenses neutrophil killing of fungal cells, leading to improved survival.

Splenic TNF-α signaling potentiates the innate-to-adaptive transition of antiviral NK cells

I made an excursion into the Humboldt vs. neoliberal university model, some (left) Alasdair MacIntyre takes on virtues in academia and ideas about what to change and how. 😉 Check out my chapter about neoliberalism in academia in this new book: www.sciencedirect.com/science/arti...

You should follow my amazing mentor joe 😊 we have a lot cooking in the lab about to go out, if you are interested in NK cells (and a little CD8 and even B cells 😂) give a follow

Immunologists (especially if interested in NK cells) should follow @labwaggoner.bsky.social, on twitter the best way to not miss papers 😅 stephen you should ask @rodrahimi.bsky.social to be added to an “immunology starter pack”

To populate my Bluesky and people know what I do: I am an MD turned immunology "basic" researcher. In the past I did adoptive T cell therapy and then fate mapping in the Buchholz lab in Munich: CD8+ T cells in MCMV: www.nature.com/articles/s41...
