    Sensing of nutrients by CPT1C regulates late endosome/lysosome anterograde transport and axon growth

    Marta Palomo-Guerrero, Rut Fadó ... Núria Casals
    The pseudoenzyme CPT1C is able to sense changes in intracellular malonyl-CoA levels caused by nutrients or energy stress and regulate late endosomes/lysosomes anterograde transport, necessary for proper axon growth.

    The Mla pathway in Acinetobacter baumannii has no demonstrable role in anterograde lipid transport

    Matthew J Powers, Brent W Simpson, M Stephen Trent
    An outer membrane vesicle pulse-chase assay demonstrates that the Acinetobacter baumannii Mla system is a retrograde lipid transporter.

    The GTPase IFT27 is involved in both anterograde and retrograde intraflagellar transport

    Diego Huet, Thierry Blisnick ... Philippe Bastin
    A small GTPase within the flagellum can participate in the control of transport from the base to the tip of the flagellum, and back again.

    Inter-Golgi transport mediated by COPI-containing vesicles carrying small cargoes

    Patrina A Pellett, Felix Dietrich ... Grégory Lavieu
    Evidence that certain proteins can be transported between Golgi via structures that resemble COPI vesicles suggests that these vesicles could also be involved in the transport of proteins from the cis to the trans face of the Golgi.

    A minimal self-organisation model of the Golgi apparatus

    Quentin Vagne, Jean-Patrick Vrel, Pierre Sens
    An unbiased model for the self-organisation of the Golgi apparatus displays either anterograde vesicular transport or cisternal maturation depending on ratios of budding, fusion and biochemical conversion rates.

    The Acinetobacter baumannii Mla system and glycerophospholipid transport to the outer membrane

    Cassandra Kamischke, Junping Fan ... Samuel I Miller
    An Acinetobacter baumannii ABC transporter likely facilitates transport of glycerophospholipids from the inner to the outer membrane.

    Quantitative transportomics identifies Kif5a as a major regulator of neurodegeneration

    Sahil H Shah, Lucio M Schiapparelli ... Jeffrey L Goldberg
    Transportomic analysis of the changes underlying neurodegeneration reveals the importance of Kif5a for neuronal survival and highlights the need to restore specific anterograde cargo transport to for regeneration.

    Presynaptic APP levels and synaptic homeostasis are regulated by Akt phosphorylation of huntingtin

    Julie Bruyère, Yah-Se Abada ... Frédéric Saudou
    Reducing Akt-mediated huntingtin phosphorylation decreases APP accumulation at the synapse by reducing its anterograde axonal transport and ameliorates learning and memory in a mouse model of familial Alzheimer disease.

    Dynamics of the IFT machinery at the ciliary tip

    Alexander Chien, Sheng Min Shih ... Ahmet Yildiz
    During intraflagellar transport (IFT), kinesin-II dissociates from IFT trains at the flagellar tip and its diffusion in flagella serves as a negative feedback mechanism that facilitates flagellar length control in Chlamydomonas.

    Structure of bacterial phospholipid transporter MlaFEDB with substrate bound

    Nicolas Coudray, Georgia L Isom ... Damian C Ekiert
    Structure of MlaFEDB ABC transporter with substrate bound in the outward-open pocket of MlaE provides mechanistic insights into lipid transport within the Gram-negative bacterial cell envelope.
