In their Opinion article, Hemmo Meyer @hemmo-lab.bsky.social @unidue-zmb.bsky.social, Akiko Kuma and Shuhei Nakamura discuss the concept of lysosome regeneration and provide guidance for interpreting markers and assays used to study lysosomal damage responses. journals.biologists.com/jcs/article/...
Schematic showing the diverse pathways in the lysosomal damage response.

Our opinion article is out now on: Disentangling the response to lysosomal damage journals.biologists.com/jcs/article-... It discusses the concept of lysosome regeneration and the tools and reporters for diverse branches of the pathway. Great to work with coauthors Akiko and Shuhei.

VPS13C/PARK23 initiates lipid transfer and membrane remodeling for efficient lysosomal repair
Nature Communications - Not all components of the lysosome damage response pathway have been defined. Here, the authors discover that the bridge-like lipid transport protein VPS13C senses lysosomal...

Fantastic work by Aakriti Jain @aakritijain.bsky.social in team with Claire Goul and the Laboratory for Genome Research reveals the LASER pathway and its core component TFG as critical for rapid ESCRT-dependent lysosomal membrane repair, pointing to a deep connection with neurodegeneration!

VCP/p97’s accessory adapters (FAF1, FAF2, UBXN7) boost unfolding and subsequent proteasomal degradation. #ubiquitin. Our paper is out now: Science Advances www.science.org/doi/10.1126/...

The accessory adapters FAF1, FAF2, and UBXN7 accelerate proteasomal degradation by increasing prior p97-mediated substrate unfolding
A group of accessory adapters positions the p97 adapter Ufd1 to boost substrate unfolding and subsequent proteasomal degradation.

Proud to share a preprint of our paper on how bridge-like lipid transport protein VPS13C senses lysosomal membrane tension in anticipation of membrane lesions to initiate net ER-to-lysosome lipid transfer for efficient lysosomal repair www.biorxiv.org/content/10.1...

VPS13C/PARK23 initiates lipid transfer and membrane remodeling for efficient lysosomal repair
Perturbations in lysosome integrity are tightly linked to neurological disorders and ageing, but the underlying pathogenic mechanisms are incompletely understood. Using an unbiased proteomic approach,...

Excellent thesis defense by Pinki Gahlot concluding brillant work on a sensor module, SPG20-ITCH that detects lipid packing defects in the limiting membrane of permeabilized #lysosomes and initiates #lysophagy.

Lysosomal membrane homeostasis and its importance in physiology and disease
Nature Reviews Molecular Cell Biology, Published online: 04 August 2025; doi:10.1038/s41580-025-00873-wLysosomes degrade cellular components, and their membrane is an important signalling hub. Recent insights into the mechanisms that maintain lysosomal membrane homeostasis — including the interplay between membrane damage, repair, lysophagy and lysosome biogenesis — highlight their importance in physiology, in disease and during ageing.

Thrilled to share our work on the role of Ataxin-3 in lysosome regeneration published in @embojournal.org . Here we show that Atxn3 targets K48-K63 branched ubiquitin chains on damaged lysosomes and mediates restoration of lysosomal function via microautophagy. www.embopress.org/doi/full/10....
