    Feeding state-dependent regulation of developmental plasticity via CaMKI and neuroendocrine signaling

    Scott J Neal et al.
    CaMKI and neuroendocrine signaling integrate information about food status to regulate a developmental decision in C. elegans.
    1. Ecology

    Acknowledging selection at sub-organismal levels resolves controversy on pro-cooperation mechanisms

    Wenying Shou
    Building on previous work (Momeni et al., 2013), it is shown that recognizing the hierarchical organization of biological systems resolves the ongoing controversy on pro-cooperation mechanisms.

    Ankyrin-B is a PI3P effector that promotes polarized α5β1-integrin recycling via recruiting RabGAP1L to early endosomes

    Fangfei Qu et al.
    Ankyrin-B – through interactions with PI3P lipids, dynactin and RabGAP1L – functions as a critical node in the protein circuitry underlying polarized recycling of α5β1-integrin to enable haptotaxis along fibronectin gradients.

    The CNS connectome of a tadpole larva of Ciona intestinalis (L.) highlights sidedness in the brain of a chordate sibling

    Kerrianne Ryan et al.
    Serial-section EM analysis uncovers the CNS connectome of a Ciona larva, the second of any entire nervous system, and exposes left-right asymmetries in its synaptic circuits.

    Developmental programming modulates olfactory behavior in C. elegans via endogenous RNAi pathways

    Jennie R Sims et al.
    The OSM-9 TRPV channel is differentially regulated due to developmental programming via modulation by TGF-β signaling, endogenous RNAi and chromatin remodeling pathways.

    Selective agonist of TRPML2 reveals direct role in chemokine release from innate immune cells

    Eva Plesch et al.
    Direct and selective activation of TRPML2 promotes macrophage migration through release of CCL2.

    TIAM-1/GEF can shape somatosensory dendrites independently of its GEF activity by regulating F-actin localization

    Leo TH Tang et al.
    The DMA-1/LRR-TM cell surface receptor signals through partially redundant pathways to cell-autonomously pattern dendrites, including by directly forming a complex with both the TIAM-1/GEF and ACT-4/Actin.

    Frazzled promotes growth cone attachment at the source of a Netrin gradient in the Drosophila visual system

    Orkun Akin, S Lawrence Zipursky
    Direct observation in the developing fly brain indicates that the response of a growth cone in a gradient of a guidance cue is adhesion to the source of the cue rather than attraction by the gradient.
