A combination of spatial proteomic and autophagic flux approaches was used to reveal the landscape of turnover of damaged lysosomes, demonstrating a key role for the autophagy receptor TAX1BP1 and its associated kinase TBK1 in both HeLa cells and iNeurons.

Erythroid-enriched BMP2K kinase, in addition to its predicted function in endocytosis, regulates distribution and abundance of COPII assemblies and autophagic degradation through opposing actions of its two splicing variants.
A genetic approach in Caenorhabditis elegans shows that the cleaved and cytosolic form of the ubiquitin-like protein LGG-1/GABARAP is sufficient for both autophagy and embryonic development.

Autophagy is required for CD8+ T cell memory formation; in aged individuals autophagy levels are diminished, and increasing autophagy enhances their CD8+ T cell responses.
Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.
The most common Parkinson’s disease-associated mutation, LRRK2 G2019S, impairs mitophagy in clinically relevant cells within the mouse brain and this defect can be reversed using a novel LRRK2 inhibitor.
Modulation of histone levels in gut enterocytes by rapamycin treatment alters chromatin organisation and induces intestinal autophagy through transcriptional regulation to prevent age-related decline in the intestine and extend lifespan.
