LLOMe has long been used to study lysosomal damage, yet how it works has remained a mystery.
Using cryo-electron tomography, we show it forms amyloid structures inside lysosomes that mechanically rupture membranes – revealing a new paradigm for lysosomal failure.

Also check out a fantastic complementary study from the Jeffery Kelly lab! They independently uncover how LLOMe disrupts lysosomes by forming amyloids that may act as seeds for pathological aggregates

Cathepsin C–Catalyzed Ligation Generates Intralysosomal Amyloid Fibrils from Dipeptide Esters
Amyloid fibril-associated endolysosomal dysfunction is implicated in multiple neurodegenerative diseases. We report the rapid generation of intralysosomal amyloid fibrils by simply treating cells with certain dipeptide methyl esters. Cathepsin C mediates the ligation of dipeptides into oligopeptides that, sequence-dependently, self-assemble into amyloid fibrils. Progressive fibril growth, not fibril deposition, mediates lysosomal membrane permeabilization. Cryo-electron tomography studies reveal intralysosomal fibrils and broken lysosomal membranes upon dipeptide treatment. Certain oligopeptide fibril structures are competent to cross-seed the aggregation of neurodegeneration-associated Tau(P301S) at lysosomal sites. Similarly, the degree of lysosomal membrane permeabilization and ESCRT-repair response can be tuned with dipeptide sequence variation. The presented Cathepsin C-dependent amyloid fibril formation approach lends itself toward the development of novel tools to further probe lysosomal biology and pathobiology. ### Competing Interest Statement The authors have declared no competing interest.

In this study we investigate the architecture of aminopeptidase-1 condensates directly inside cells at molecular resolution! We show how transient local structures can mediate phase separation, directly linking amino acid sequence to condensate material properties and biological function.

Our study provides insights into the process of initiation during selective autophagy and offers new ideas for developing approaches to selectively degrade unwanted cellular material by autophagy.

3) Experiments using mammalian cell systems reveal striking similarities where FIP200 (Atg11 homologue) clusters on the cargo surface, connecting the phagophore assembly site to the ER. Changing receptor affinity of p62 within condensates resulted in a degradation defect similar to yeast.
January 8, 2025 at 3:11 PM
2) The low affinity of the receptor for the cargo also allows the initiation hubs to rearrange and establish organelle contact sites necessary to form the pre-autophagosomal structure. Reconstitution of these features allowed us to transform a viral protein expressed in yeast into a neo-cargo.
January 8, 2025 at 3:11 PM
1) These low affinity interactions are important for the formation of Atg11 condensates at the cargo surface. Atg11 condensates act as initiation hubs to recruit core autophagy machinery proteins such as Atg1 and Atg9.
January 8, 2025 at 3:11 PM
What happens if you change the physical properties of an autophagic cargo? By altering the low-affinity interaction of autophagic receptors with or within their cargo, we observed a severe degradation defect in budding yeast.
