    The autophagic membrane tether ATG2A transfers lipids between membranes

    Shintaro Maeda et al.
    The autophagy protein ATG2A tethers membranes and transfers lipids between them, suggesting that autophagosome membranes grow upon the acquisition of lipids from the ER through the ATG2A bridge.

    Endosomal Rab cycles regulate Parkin-mediated mitophagy

    Koji Yamano et al.
    Parkin ubiquitination of damaged mitochondria recruits the Rab GEF, RABGEF1, to regulate downstream Rab cycles and ATG9A recruitment to growing phagophores that are participating in mitophagy.

    Parkin contributes to synaptic vesicle autophagy in Bassoon-deficient mice

    Sheila Hoffmann-Conaway et al.
    The presynaptic scaffolding protein Bassoon is involved in regulating neurotransmitter release by controlling synaptic vesicle pool size and vesicular protein turnover through increased ubiquitination and Parkin-dependent autophagy.

    Two distinct mechanisms target the autophagy-related E3 complex to the pre-autophagosomal structure

    Kumi Harada et al.
    How the autophagy-related E3 complex localizes to pre-autophagosomal structures and a non-E3 function of the complex were revealed, significantly advancing our understanding of the nucleation step in autophagosome formation.

    Host autophagy machinery is diverted to the pathogen interface to mediate focal defense responses against the Irish potato famine pathogen

    Yasin F Dagdas et al.
    Defense-related selective autophagy mediated by the antimicrobial autophagy cargo receptor NBR1/Joka2 is diverted to pathogen penetration sites to restrict plant colonization by the oomycete pathogen Phytophthora infestans.

    Multiplex image-based autophagy RNAi screening identifies SMCR8 as ULK1 kinase activity and gene expression regulator

    Jennifer Jung et al.
    An image-based multiplex autophagosome RNAi screen targeting all Rab GTPases as well as their GAPs and GEFs identifies the Rab GEF SMCR8 as multifaceted autophagy modulator, which regulates kinase activity and gene expression of ULK1.

    Elucidation of the anti-autophagy mechanism of the Legionella effector RavZ using semisynthetic LC3 proteins

    Aimin Yang et al.
    Legionella effector RavZ evades host autophagy by extracting LC3-PE from the membrane before deconjugation.

    Spatiotemporal regulation of autophagy during Caenorhabditis elegans aging

    Jessica T Chang et al.
    Autophagic flux assays in the nematode Caenorhabditis elegans suggest that autophagy decreases during normal aging, whereas long-lived daf-2 and glp-1 mutants maintain autophagic capacity in distinct spatiotemporal-specific manners to extend lifespan.
