Here the Prentki lab proposes that inhibition of monoacylglycerol (MAG) hydrolase α/β-hydrolase domain-containing 6 (ABHD6) in WAT is a therapeutic strategy for improving the health of adipose tissue #obesity www.sciencedirect.com/science/arti...

Suppression of adipocyte ABHD6 favors anti-inflammatory and adipogenic programs to preserve adipose tissue fitness in obesity
Some individuals exhibit metabolically healthy obesity, characterized by the expansion of white adipose tissue (WAT) without associated complications.…

Regulatory T cells in brown adipose tissue safeguard thermogenesis by restraining interferon-γ–producing lymphocytes
Brown adipose tissue hosts a distinct population of Treg cells that preserves thermogenesis by controlling local interferon-γ production.

I've been doing this for 30 years & I still can't believe that when people ask me what I do for a living I get to tell them "I'm a scientist". It feels like a kid's fantasy career that they dress up as for Halloween, like "astronaut" or "pirate". I feel very lucky I get to do this day in & day out.

Today in @naturecomms.bsky.social we show the #FutileCreatineCycle plays a key role in #thermogenesis, independent of UCP1. We also challenge the belief that brown adipocytes lack enough ATP synthase for thermogenesis. Congrats to Jakub Bunk! @mcgillgci.bsky.social Full paper: rdcu.be/egoV7

Nature Communications - Thermogenesis by brown adipose tissue has long been thought to be solely controlled by uncoupling protein 1 (UCP1). Here, the authors show that energy expenditure in brown...
