The pathways of secretory cargo export at the endoplasmic reticulum Nature Communications - The author presents an overview of the complex challenge of protein export from the Endoplasmic Reticulum, and discusses how cells may deploy novel pathways utilizing...

A terrific perspective from Vivek Malhotra @naturecomms.bsky.social on the fundamental importance of pathways and mechanisms by which cells secrete proteins, ensuring their delivery in the correct quantities and at the appropriate times.
Interesting section on unanswered questions.

We've been studying mechanisms of resilience that protect lysosomes from damage and wrote a review on the topic. We consider lysosomal stress and damage on a spectrum. Please help me share as this is my first post 😀 and I don't have many followers! 🙏 Open Access: www.embopress.org/doi/full/10....

Proximity proteomics reveals a mechanism of fatty acid transfer at lipid droplet-mitochondria- endoplasmic reticulum contact sites - Nature Communications Protein-mediated transport is implicated in trafficking fatty acids at contact sites of lipid droplets and mitochondria. Here, the authors use proteomics to catalogue the proteins at this contact site...
