Asthma is a chronic disease characterized by acute, intermittent, recurrent episodes of airway inflammation. A decade of work developing the tools, techniques and collaborations needed to figure out how CD4+ T cells in the lungs propagate disease can be found here:

Tertiary lymphoid structures support the development of allergen-specific progenitor CD4+ T cells
Tissue-resident memory CD4+ T cells (TRM) are key sentinels of the adaptive immune response that provide a rapid, robust inflammatory response upon reactivation in non-lymphoid tissues. While CD4+ TRM...

Thanks @10xgenomics.bsky.social for the shout out and for making your data publicly available

Why waste precious resources ($$) to reinvent data that already exists? Cool human datasets ready to go

(Although now we have scratched the spatial itch, we may need to do more @chinweetan.bsky.social 🤔)

How do cytokines tune immune helpers?
Nature Immunology study from @groomlab.bsky.social ’s lab at @wehi-research.bsky.social used @10xgenomics.bsky.social single-cell & spatial tech to map T follicular helper (TFH) cells diversity.

A small primer on the #NobelPrize awarded to Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi today. This prize was for combining two separate fields of immunology research - genetic research on IPEX and immunology research of regulatory T cells (#Tregs), with enormous impact on biology/medicine

BREAKING: The Nobel Prize in Physiology or Medicine has been awarded jointly to Mary E. Brunkow, Fred Ramsdell, and Shimon Sakaguchi "for their discoveries concerning peripheral immune tolerance"

Stay tuned for more.

If the immune system is an army...
...
would you rather rely on one “super warrior” — or on a diverse team of fighters, even if none of them is the single strongest?

I’d go with the team.

Why? Check out our new study, just published in Science Immunology: www.science.org/doi/10.1126/...

🧵 (1/2) Interested in tertiary lymphoid structures (TLSs)? Check out our latest review, where we chart how TLSs form across organs and contexts — from lung to liver, CNS, skin, gut & more — and their dual roles in protection vs. pathology.
Tertiary Lymphoid Structures Across Organs: Context, Composition, and Clinical Levers
Tertiary lymphoid structures (TLSs) arise in non-lymphoid tissues in response to persistent antigen stimulation and chronic inflammation. Spanning organs from lung and liver to meninges, skin, and be....

For our #flowcytometry peeps, would you like to have a single fix/perm protocol that is optimised for everything? One that preserves fluorophores while allowing simultaneous TF and cytokine staining? How about 100-fold cheaper?

You got it:

🧵How to write and manage your first research budgets

The point of funding is to convert it into quality research. A well-spent research budget should fund the idea it was raised on, plus revision experiments, plus preliminary data for the next grant. So you need to spend, while avoiding waste.
