    Mechanism of cargo-directed Atg8 conjugation during selective autophagy

    Dorotea Fracchiolla et al.
    Autophagic cargo receptors recruit the E3-like enzyme for Atg8 lipid conjugation to the cargo and thereby promote local formation of Atg8-positive autophagosomal membranes.

    Oligomerization of p62 allows for selection of ubiquitinated cargo and isolation membrane during selective autophagy

    Bettina Wurzer et al.
    Oligomerization of p62/SQSTM1 generates high avidity binding regions that enable it to spatially select for concentrated ubiquitin and ATG8-family proteins.

    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.

    Autophagy linked FYVE (Alfy/WDFY3) is required for establishing neuronal connectivity in the mammalian brain

    Joanna M Dragich et al.
    Loss of function of the selective autophagy adaptor protein Alfy/Wdfy3 leads to profound wiring defects from the forebrain through to the spinal cord, highlighting the growing importance for macroautophagy in the developing brain.

    Neuronal TORC1 modulates longevity via AMPK and cell nonautonomous regulation of mitochondrial dynamics in C. elegans

    Yue Zhang et al.
    Modulating the nutrient sensor TORC1 only in neurons in C. elegans is sufficient to regulate systemic longevity via inter-tissue signals that remodel mitochondria networks in non neuronal cells.

    A critical role of VMP1 in lipoprotein secretion

    Hideaki Morishita et al.
    The ER transmembrane protein VMP1 is important for release of lipoproteins from the ER membrane into the ER lumen for secretion.
