Mesa Laboratory

Looking for motivated postdocs interested in doing exciting research at the intersection of immunology and regenerative biology. We use intravital two-photon imaging to track and manipulate immune cell behavior at the single-cell level in live animals mesa-lab.org Apply: apply.interfolio.com/180660

Antigen specificity of clonally enriched CD8+ T cells in multiple sclerosis - Nature Immunology Sabatino and colleagues examine expanded CD8+ T cell clonotypes from a small cohort of multiple sclerosis patients. They identified several cognate peptide epitopes that derive from Epstein–Barr virus...

Also on mine. It beautifully connects self–non-self and danger theories, showing that self-attack occurs only when antigens are sensed in the context of damage, without ‘self’ classification.

As 2025 is drawing to a close, @jem.org would like to highlight all of the women who have contributed to the #WomenInSTEM #Viewpoint series over the last 3 years! Learn more about their scientific journeys on the path to independence here 👉 tinyurl.com/2wrxk4mk

Antibody-lectin chimeras for glyco-immune checkpoint blockade - Nature Biotechnology Cancer immunotherapy benefits from antibody-lectin chimeras that block glyco-immune checkpoints.

Out now: We present antibody-lectin chimeras (AbLecs) as a molecular platform to target sugars, or glycans, for cancer immunotherapy.

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...

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:

Nice!

Simply wonderful!

Thrilled to have our latest research @wehi-research.bsky.social published in @natimmunol.nature.com
www.nature.com/articles/s41...

This work was an outstanding partnership between talented PhD student Len Dalit (now postdoc, no 🦋) and bioinformatician @chinweetan.bsky.social

Thread below...

And she will also present a poster tomorrow afternoon. Go say hi! #EMBObarrierTissues

I wish I could be there!
Our amazing @annarudnitsky.bsky.social will give a talk on Friday — don’t miss it!

The #IUIS2025 was way above my expectations! It was so great to meet old and new friends and to share our work. @iuis-online.bsky.social

Was great to meet you in person Brenda. Keep up the great work.

It was mind blowing

Great keynote lecture by Ruslan Medzhitov on how the “educated” immune system of pet shop mice allows them to resist experimental allergic sensitisation. Thought provoking, as usual. #IUIS2025.

Some pics from the #RisingStars Day 2!

Don't forget to share — which sessions have you liked the most so far?

#ImmunologyWithoutBorders

Meet Dr @KedmiRanit, PI at Weizmann Institute. Her research reveals how immune cells coordinate to shape T cell responses. At #IUIS2025, she’ll present “A coordinated cellular network regulates intestinal tolerance.” 🔬🌍 https://loom.ly/CwagY2g #RisingStars2025 #RoadtoVienna

Very cool!

How we’re rebuilding the Weizmann Institute — and our hopes for a better future Scientific research is at the heart of Israel’s success and has worldwide benefits. Our work will continue despite adversity.
