Please share: OHSU is hiring an Assistant Prof. in the Dept. of Chemical Physiology & Biochemistry. We are looking for a chemical biologist who will apply novel chemical tools in physiological systems. Apply online: www.ohsu.edu/human-resour... (Job # 2026-41667).

#lipidtime: It's a lipid universe. Today in Nature we publish the Lipid Brain Atlas, the first map of membrane lipid composition across the entire mouse brain, a layer of organisation that cell-type and transcript maps had left out. #lipidomics #neuroscience #BrainAtlas

WE'RE HIRING! Thanks to some recent successes with NIH funding, we're seeking two new postdoctoral scholars to join our team. See below for details. Please share widely and feel free to reach out with any questions!

To understand what a lipid does, we need to know its partners. Which proteins bind lipids and how can we capture those interactions? Our new Nature Protocols paper provides a practical, step-by-step guide to identifying lipid-binding proteins. 🧵

Excited to share our latest paper where we report an MR1-specific nanobody that blocks MR1-mediated T-cell activation. Congrats to Tim Bates, Corinna from David Lewinsohn’s lab, and thanks to @jburkevic.bsky.social for HDX-MS support! @ohsunews.bsky.social academic.oup.com/jimmunol/art...

Thrilled to share our latest work showing that the bridge lipid transport protein ATG2A transfers diacylglycerol (DAG), and some TAG/PA, from the ER to LDs, thereby recruiting DGAT2 to drive local TAG synthesis, promoting LD expansion while protecting ER membranes. www.nature.com/articles/s41...

Beautiful work! Congrats @abdourachidthiam.bsky.social and the team!

Lange et al. identify a lipid droplet quality control pathway in which FSP1 safeguards stored neutral lipids from lipid peroxidation, thereby preventing the induction of ferroptosis.
