    Quantitative proteomics reveals the selectivity of ubiquitin-binding autophagy receptors in the turnover of damaged lysosomes by lysophagy

    Vinay V Eapen, Sharan Swarup ... J Wade Harper
    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.

    An effector of the Irish potato famine pathogen antagonizes a host autophagy cargo receptor

    Yasin F Dagdas, Khaoula Belhaj ... Tolga O Bozkurt
    A plant pathogen effector evolved a short linear motif to subvert autophagic defenses by antagonising a host cargo receptor.

    Splicing variation of BMP2K balances abundance of COPII assemblies and autophagic degradation in erythroid cells

    Jaroslaw Cendrowski, Marta Kaczmarek ... Marta Miaczynska
    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.

    LGG-1/GABARAP lipidation is not required for autophagy and development in Caenorhabditis elegans

    Romane Leboutet, Céline Largeau ... Renaud Legouis
    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 a critical regulator of memory CD8+ T cell formation

    Daniel J Puleston, Hanlin Zhang ... Anna Katharina Simon
    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.

    Autophagy in T cells from aged donors is maintained by spermidine and correlates with function and vaccine responses

    Ghada Alsaleh, Isabel Panse ... Anna Katharina Simon
    Declining TFEB and autophagy levels with age are key to poor vaccination efficacy in the elderly.

    Genetic screen in Drosophila muscle identifies autophagy-mediated T-tubule remodeling and a Rab2 role in autophagy

    Naonobu Fujita, Wilson Huang ... Amy A Kiger
    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.

    Pharmacological rescue of impaired mitophagy in Parkinson’s disease-related LRRK2 G2019S knock-in mice

    Francois Singh, Alan R Prescott ... Ian G Ganley
    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.

    A TORC1-histone axis regulates chromatin organisation and non-canonical induction of autophagy to ameliorate ageing

    Yu-Xuan Lu, Jennifer C Regan ... Linda Partridge
    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.
