    Endogenous opioids in the nucleus accumbens promote approach to high-fat food in the absence of caloric need

    Kevin Caref, Saleem M Nicola
    Activation of mu-opioid receptors in the nucleus accumbens by their endogenous ligands promotes consumption of high-fat food in sated but not hungry rats, via enhancement of a neural signal that promotes cued approach behavior.

    High fat diet induces microbiota-dependent silencing of enteroendocrine cells

    Lihua Ye et al.
    Enteroendocrine cells sense nutrients in the gut and regulate digestive physiology but are rendered insensitive following fat ingestion due to alteration of gut microbiota.

    The novel SH3 domain protein Dlish/CG10933 mediates fat signaling in Drosophila by binding and regulating Dachs

    Yifei Zhang et al.
    The Fat-regulated scaffolding protein Dlish controls the activity, levels and cortical localization of Warts-inhibiting myosin Dachs by linking Dachs to a critical Dachs regulator, the DHHC palmitoyltransferase Approximated, and to the Fat-mediated regulation of Dachs stability.

    The Drosophila F-box protein Fbxl7 binds to the protocadherin Fat and regulates Dachs localization and Hippo signaling

    Justin A Bosch et al.
    The F-box protein Fbxl7 is a direct effector of the protocadherin Fat and functions in downstream pathways that regulate tissue shape and size.

    Early postnatal interactions between beige adipocytes and sympathetic neurites regulate innervation of subcutaneous fat

    Jingyi Chi et al.
    The regulation of sympathetic innervation density by beige adipocytes in subcutaneous fat is important during a critical developmental window, but dispensable during adulthood.

    High-fat diet enhances starvation-induced hyperactivity via sensitizing hunger-sensing neurons in Drosophila

    Rui Huang et al.
    Fruit flies fed with high-fats diets are hyper-sensitive to a hunger hormone AKH and exhibit enhanced food-seeking behavior when starved.

    Induction of the IL-1RII decoy receptor by NFAT/FOXP3 blocks IL-1β-dependent response of Th17 cells

    Dong Hyun Kim et al.
    Cellular immunological and biochemical analyses reveal how decoy IL-1RII is induced by human CD4+ T cells upon TCR-stimulation and regulates the Th17-Treg balance by modulating IL-1β responsiveness in IL-1RI+ cells.

    Hypothalamic transcriptomes of 99 mouse strains reveal trans eQTL hotspots, splicing QTLs and novel non-coding genes

    Yehudit Hasin-Brumshtein et al.
    In depth characterization of gene expression in the mouse hypothalamus will facilitate understanding of the molecular pathways that affect metabolic traits and discovers new genes associated with these pathways.

    Hedgehog signaling via Gli2 prevents obesity induced by high-fat diet in adult mice

    Yu Shi, Fanxin Long
    Targeted activation of Hedgehog signalling via Gli2 facilitated the reduction of high-fat-diet-induced obesity and improvement of whole-body glucose tolerance and insulin sensitivity in adult mice.
