We had an amazing time with the ABC family and already miss you all! Can’t wait to hear your exciting talks, have great discussions, and hit the slopes of the Alps again. #ABC2025 See you next time!🗻⛷️🚠🧬🧫🧪💙

Maria Zoghbi says she's in "ABC transporter heaven" at #ABC2025 🥰 A closer look at ABCB10 transporter dynamics may well keep you on cloud number nine... ☁️⭐️

Moving into mitochondria with Marc Liesa! ABCB10, heme and redox stress: Some projects are literally a blood.bath... maybe sounds familiar to some other researchers out there? 😅🩸

Preprint alert!! How zonated hepatocytes adapt to changes in lipid influx due to fasting or a Western diet (WD). We developed a microscopy-based phenotyping method called single-cell phenomics (scPhenomics) to measure the features of mitochondria and lipid droplets (LDs).

Join your fellow #ABC friends in the lecture hall and on the slopes for ABC2025 in Innsbruck Feb 27-Mar03! Register abc2025meeting.org and see our invited speakers´list below! See you in Innsbruck!🧬⛰️🏂🧪

Thrilled to share one of our biggest discoveries: “Inceptor binds to and directs insulin towards lysosomal degradation in beta cells”. doi.org/10.1038/s422... A tremendous collaborative effort led by JohannaSiehler, Sara Bilekova and other members of the Lickert lab @heikolickert.bsky.social

Do you know who Douglas Prasher is? Many don't, even though he is the person who cloned the original #GFP gene in the late 1980s. In my short history of plant light #microscopy I also cover a bit of his story - & why he is relatively unknown today, despite the importance of his work. See this 🧵👇

Highly motivated after the kick-off meeting with @CSIC colleagues and president @delPinoE for the preparation of a Science 4 Policy report about Metabolic Diseases, together with @DiabetesLabIBGM, María Monsalve, Angela M Valverde, María Angeles Martín and Yolanda Sanz.

Very excited with our new study just published in Redox Biology! We show that mitochondrial redox in hepatocytes determines the pro-inflammatory capacity of infiltrated neutrophils in alcohol-induced hepatitis.

It is out! Here we describe a new method to isolate peridroplet mitochondria (PDM) from white adipose tissue (WAT), revealing unique functional characteristics in WAT PDM determined by lipid droplet size.

Very excited to see where biliverdin binds to ABCB10 for the first time! Cryo-EM structures of mitochondrial ABC transporter ABCB10 in apo and biliverdin-bound form ⁦@NatureComms⁩ ⁦@mikeshum22⁩

Very excited to share our new study @embojournal with @OrianShirihai⁩ and led by ⁦@R_AcinPerez⁩ and ⁦@CrisBenincaPhD⁩. We find that inhibiting mitochondrial complex V reverse activity restores energy homeostasis in mito pathologies.

Had a great time reading the paper and writing the news and views. Congrats to @tom_mcphagy lab! The EMBO Journal | The goodies of chelated fat: iron‐regulated lipid droplet biogenesis precedes and preserves mitophagy

Very excited to see this paper out @MolMetab! We show that ABCB10 actions in beta cells contribute to insulin resistance. Congrats to @mikeshum22 and all co-authors. Thanks to @bcorkey @JimJohnsonSci for their previous studies guiding our work.

Very happy to share our latest publication led by @mikeshum22, defining that ABCB10 exports biliverdin outside mitochondria, which induces a redox state in hepatocytes that promotes insulin resistance and steatosis.

Happy to share the final version of our @MolMetab review . We propose that the co-existence of 3 functionally independent sub-populations of mitochondria can clarify the conundrum of the role of mitochondria function and ROS in NAFLD (pic by @JNgo1412)

Congratulations to @JNgo1412, @IlanBenador , Alex, Laurent, @MichaelaVeliova , @mikeshum22, Karen Reue and @OrianShirihai for our publication in @STARProtocols describing in detail the isolation of peridroplet mitochondria from BAT. .
