How does fever work? Our new Science paper shows how elevated body temperature can protect against severe influenza and that avian-origin viruses escape this defence. This is likely one reason why bird flus and some pandemic influenzas can be so severe.🧵 www.science.org/doi/10.1126/...

Really nice work from our neighbours Stephanie Fulton and team investigating links between inflammation, anxiety, and microglia! www.sciencedirect.com/science/arti...

My first first-author paper is published! At the intersection of metabolism and reproduction, we wrote this review with a broad audience in mind, and hope that there is something for everyone. Excited for the future of the field and honored to be a part of it! academic.oup.com/endo/article...

Woo hoo @paulvander24.bsky.social !

Mars was the Roman god of war. That’s why we say ‘martial arts,' ‘martial law,' and 'court martial.' Marshall was the Roman god of designer fashion at discount prices. That’s why we have Marshall’s.

We are looking for a postdoc fellow to join the group. Focus on studying feeding-relevant slow dynamics in the brain using invivo microscopy approaches. Please share with anyone interested. Thank you. www.training.nih.gov/jobs/pdf-inf...

Proud to announce the publication of our new paper describing the design, chemical synthesis and testing of a novel class of Complement 3a Receptor (C3aR) agonists and antagonists derived from the TLQP-21 peptide @pubs.acs.org Journal of Medicinal Chemistry pubs.acs.org/doi/10.1021/...

We are proud of Omprakash Singh's new study just out in Cell Reports. Supported by Sepideh Sheybani-Deloui et al, Om's work identifies GHSR expressing SCN neurons as regulating food intake + feed efficiency at a single time of day, accounting for at least 7% of a mouse's BW doi.org/10.1016/j.ce...

Rigorous dissection of the signaling mechanisms and circuits underlying GLP1R agonist weight loss effects mice. Huge achievement by Claire Gao and team @mikekrashes.bsky.social. Potential avenues for harnessing complexity of signaling to create novel treatments. www.biorxiv.org/content/10.1...

Amid lots of uncertainty, anger, and exhaustion I am excited to share this work from my incredibly talented MSTP and @nuincomm.bsky.social student Haley Province. In it we explore the fascinating and powerful anti-aversive properties of GIPR agonists

Huge congratulations to Ivan and the rest of the @mikekrashes.bsky.social lab—formidable job! Grateful to have contributed a tiny piece to this.

🧵1/15 Delighted to share our study on the naked mole-rat (NMR): a mammal with bizarre thermal biology, notorious longevity, and cancer resistance. But how do NMRs maintain (or fail to maintain) their body temperature? Our latest work digs deep! #ThermalBiology #Thermogenesis

big if true

New Pub 🚨: Read how we’re tying a specific GABA A receptor subtype to the impact of HFD on central cardiac vagal motor neurons. www.cell.com/iscience/ful...

This is brilliant! And not by Charles Dar-wine 😂

An example of what we in the NIH Intramural program can accomplish. Excited to share our latest paper in close collaboration with Nick Ryba's group. We examined how inflammation transforms representation in somatosensory neurons to cause pain. Lots of surprises here: www.nature.com/articles/s41...

For >20 years obesity was thought to be associated with reduced dopamine receptors in brain reward regions. Now, a big study by @vdarcey.bsky.social shows that this may be have been an artifact (top figure panel) due to brain dopamine tone being positively associated with body fat (bottom).

What would Plato say about systems biology? In his Allegory of the Cave, prisoners can only see shadows on a wall and so they have a distorted reality. Also our measurements of genes, RNAs, proteins & metabolites are the shadows, not the reality of the complex biological systems.
