Schematic representation of Rab GTPases acting as “eat me” signals for selective autophagy.
In this week's #mitophagy papers, Rab GTPases take the centre stage, with a systematic study their role in autophagy, showing that multiple "Rabs" selectively mediate the degradation of mitochondria and other cellular components.

Groundbreaking study in Cell from @leventallab.bsky.social: phospholipid asymmetry is a defining feature of the plasma membrane and cholesterol fills the holes — major implications for how this membrane works. A #lipidtime must-read! www.cell.com/cell/abstrac...
Pleased to highlight a new preprint from the lab. This is the work of my longtime collaborator in the lab Allison Fay, who wanated to create new tools for disocvery biology in mycobacteria, specifically a new sysem for protein localizaton and proximity proteomics.

Shout-out to @pierredupuy.bsky.social and colleagues!
Excited to share our latest study, where we uncovered a previously unknown bacterial defense system in M. #tuberculosis: effluxosomes — dynamic membrane clusters that coordinate resistance to multiple toxic metals.

Excited to share our last study. Huge congrats to Sarah Monard, Arnaud Métais, @gclugo.bsky.social, @chrisverollet.bsky.social and all colleagues!
We have found a mysterious cell type inside TB lung lesions that seems neuron-like but isn't quite a nerve cell.
Let's dive in👇

Wow, this is big: "Fiji can now be launched in a Python-first mode, where first Python is started, then Fiji is started via the PyImageJ library. In this mode, Fiji is fully integrated with the active Python environment"

#Cellpose 3 paper now out. Not all images are perfect. Restore your images with Cellpose3 to get better segmentations, w/ @marius10p.bsky.social www.nature.com/articles/s41...
1. A thread about the value of doing "slow science": When I was in grad school I heard this (likely apocryphal) story about one of my favourite scientists: Barbara McClintock.
It’s incredibly hard to study lipids in biological membranes on the nanoscale. You need near-perfect information on both membrane ultrastructure and lipid density, which usually isn’t attainable. Lipid-CLEM brought to you by @mathilda95.bsky.social changes that.

Fantastic resource for bio icons: NIH Bioart Source
Build figures, presentations, and illustrations with 2,000+ science and medical art visuals. This collection of high-quality, scientifically accurate vectors, #icons, and brushes is freely available within the public domain. bioart.niaid.nih.gov
The #biovoxxel figure tools provide a convenient way in saving SVG vector graphic from Fiji and create publication figures in Inkscape.
Thanks to Ved Sharma those SVGs can now also be opened in the browser and even in Adobe Illustrator, if you really have to use it (I won't blame you 😉)

Thank you !
😎 awesome story! A must-read for a cellular-microbiologist working on Mtb! Congrats 🍾
Thank you !
Your story on OSBP came at the right time to help moving forward !
More in the article about the membrane repair, and who is probably repairing it when lysoview reappears and LC3 disappears.
I deeply thank everyone that got involved in this, in particular Volker that let me explore the crazy ideas I had sometimes.
The autophagosome itself was not getting acidic while showing some presence of LAMP1 so it did fuse with some acidic compartment without showing it with Lysoview.
When Lysoview (same stuff than Lysotracker) was added, it's more interesting where actually the acidity of the MCV is lost before LC3 recruitment, showing membrane damages. As seen below, the acidity could recover with a loss of signal of LC3, showing the membrane was intact again /repaired:
An intriguing observation was that LC3 recruitment on the Mtb phagosome (MCV) could be transient / reversible:
The final version of our story on autophagy and time-lapse imaging is out: doi.org/10.1371/jour...
(Corrected one expected on the 14th). This questioned a bit the direct role of xenophagy to digest Mtb, but show that is appearance may be useful to track phagosomal integrity in time-lapse imaging 👇
