Delighted to share our latest paper - A host-directed adjuvant sensitizes intracellular bacterial persisters to antibiotics. Excellently led by Dr. Kuan-Yi Lu. We think it's a great proof-of-concept that altering immune cell behavior can make antibiotics work better www.nature.com/articles/s41...

A host-directed adjuvant sensitizes intracellular bacterial persisters to antibiotics - Nature Microbiology

The authors developed a screen to find compounds that modulate intracellular Staphylococcus aureus metabolism and discovered KL1, which sensitizes persisters to antibiotics by reversing host-induced tolerance.

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...

Hello everyone! I am a postdoc in mucosal immunology and I am looking for new postdoc position in Europe! I know a lot about gut mast cells, but also CD4 T cells and type 2/3 immunity in general. I've worked with single cell sequencing and neuroimmune interactions. Feel free to share! Thank you! ♥️🥼👩‍🔬

This is absolutely brilliant🤩.
Finding the right buffer set that you can use across most all #FACS needs… And at a fraction of cost… Love it👇🏻
Kudos to @labliston.bsky.social to dedicate time and effort to this….

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?

Just take a look. The Foxp3 fix/perm kit is good for TFs, but kills endogenous GFP. The eBio preserves GFP, but is incomplete at allowing TF staining. Burton's Best Buffer is as good as the best under all conditions (except phospho-flow), and preserves dye integrity too.

Plus it is dirt cheap. 🎤
