    Endocytosis at the Drosophila blood–brain barrier as a function for sleep

    Gregory Artiushin, Shirley L Zhang ... Amita Sehgal
    Endocytosis through the Drosophila blood–brain barrier influences and depends upon sleep.
    1. Neuroscience

    Modulation of sleep by trafficking of lipids through the Drosophila blood-brain barrier

    Fu Li, Gregory Artiushin, Amita Sehgal
    Metabolites, such as acylcarnitines, accumulate in Drosophila heads when endocytosis is blocked and reflects an increased need for sleep.

    Decoupling kinematics and mechanics reveals coding properties of trigeminal ganglion neurons in the rat vibrissal system

    Nicholas E Bush, Christopher L Schroeder ... Mitra JZ Hartmann
    Primary sensory neurons of the rat whisker system encode contact with objects in terms of the forces exerted on whiskers, rather than the induced whisker movements.

    Identification of Redeye, a new sleep-regulating protein whose expression is modulated by sleep amount

    Mi Shi, Zhifeng Yue ... Amita Sehgal
    A gene found in Drosophila, and named redeye, encodes a protein that accumulates during sleep deprivation and forms part of the homeostatic system that promotes and maintains sleep.

    Evidence for a role of human blood-borne factors in mediating age-associated changes in molecular circadian rhythms

    Jessica E Schwarz, Antonijo Mrčela ... Amita Sehgal
    Blood-borne factors contribute to changes in the circadian transcriptome with age.

    Neural clocks and Neuropeptide F/Y regulate circadian gene expression in a peripheral metabolic tissue

    Renske Erion, Anna N King ... Amita Sehgal
    Neuropeptide F/Y from neurons drives rhythmic expression of detoxification-related genes in a peripheral metabolic tissue in flies and mice.

    Short and long sleeping mutants reveal links between sleep and macroautophagy

    Joseph L Bedont, Hirofumi Toda ... Amita Sehgal
    Unbiased and targeted genetic approaches reveal a link between sleep and autophagy that could be relevant for sleep function, and for understanding pathological consequences of chronic sleep loss.

    Altered hippocampal interneuron activity precedes ictal onset

    Mitra L Miri, Martin Vinck ... Jessica A Cardin
    GABAergic interneuron populations in the hippocampus exhibit cell-type-specific patterns of disruption in advance of seizure onset.

    Sleep deprivation suppresses aggression in Drosophila

    Matthew S Kayser, Benjamin Mainwaring ... Amita Sehgal
    A single night of sleep deprivation suppresses fighting behaviors in male fruit flies, with consequent impairments in reproductive fitness.

    Bone marrow adipocytes drive the development of tissue invasive Ly6Chigh monocytes during obesity

    Parastoo Boroumand, David C Prescott ... Amira Klip
    Diet-induced obesity in mice led to a duration of diet-dependent bone marrow adipocyte whitening, which drove monocyte expansion and skewing towards a tissue-invasive phenotype, likely contributing to ensuing tissue infiltration that accompanies obesity and diabetes.
