It does raise the question of why the thymus hate? There should be a campaign to stop the thymus hate!

I think my lab works on immunometabolism 🤔🤷‍♂️🤣

Cool! Have you built in a way to integrate published phenotypes?

What's the concern? They awarded it this most recent cycle. www.research.gov/grfp/Login.do

Makes me miss the talented people back home in AK. Was just back at Forest Fair, another reminder of how great it is there.

Interesting. Congrats.

3) A bit hidden in the supplement, but we propose a mostly-observational, not at all proven, mechanism of action in which HK2 localization is responsible for the defect in phagocytosis and altered metabolism. Very excited to work on this and the role of GLUT5/fructose in aging!

2) Quantitation of fructose in the brain and important clarification that our effect did not seem to be due to circulating- or CNS-derived glucose (polyol pathway) or circulating lactate.

What was new in the revision? A few things:
1) We created SLC2A5 (GLUT5) floxed mice to delete the transporter from myeloid cells during embryogenesis. This completely reversed the phagocytosis, metabolism, and behavioral phenotypes due to high fructose exposure.

Cool story. Wonder what this means when considering our finding that microglia (numbers defined by conventional protein markers, anyway) were surprisingly unaffected. rdcu.be/eoaRm

What are these other factors? 🤔
WNK1 mediates M-CSF-induced macropinocytosis to enforce macrophage lineage fidelity
Nature Communications - Tissue-resident macrophages (TRM) are important mediators of local immunity. Here the authors show that the deficiency or inhibition of a kinase, WNK1, unlinks macrophage...

Naturally, lots of questions remaining, including about how WNK1 is actually functioning to inform macrophage lineage commitment. Nevertheless, excited to see this story out. It's one of the best I have ever been a part of. @edinuni-irr.bsky.social writeup is here: edin.ac/3FtYS5B
Cell ‘drinking’ and enzyme activation shape immune cell fate
New study shows that a specific growth factor causes early-stage immune cells (macrophage precursors) to ‘drink’, which activates a special enzyme. This cell drinking and enzyme activation determines ...

5. Alissa then performed a whole bunch of experiments to demonstrate that WNK1 acts downstream of CSF1R (M-CSF receptor) to inform macrophage differentiation.

4. M-CSF-stimulated macropinocytosis is required for differentiation of myeloid progenitors into macrophages🤯.
