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

    Yehudit Hasin-Brumshtein, Arshad H Khan ... Desmond J Smith
    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.

    Developmental single-cell transcriptomics of hypothalamic POMC neurons reveal the genetic trajectories of multiple neuropeptidergic phenotypes

    Hui Yu, Marcelo Rubinstein, Malcolm J Low
    Single-cell transcriptomic analyses of hypothalamic POMC neurons performed at seven developmental ages revealed marked cellular heterogeneity and divergent developmental pathways into alternative neuronal phenotypes that lack POMC.

    Molecular consequences of peripheral Influenza A infection on cell populations in the murine hypothalamus

    René Lemcke, Christine Egebjerg ... Birgitte R Kornum
    Identification of transcriptional changes in the hypothalamus during Influenza A virus infection enhances our understanding of mechanisms underlying long-lasting neurological disturbances, potentially informing future therapeutic interventions and improving patient outcomes.

    Cellular taxonomy and spatial organization of the murine ventral posterior hypothalamus

    Laura E Mickelsen, William F Flynn ... Alexander C Jackson
    Single cell RNA–sequencing and neuroanatomical methods reveal unexpected molecular diversity and highly segregated spatial organization of neuronal cell types within the mouse ventral posterior hypothalamus, including the mammillary nuclei.

    The imprinted Zdbf2 gene finely tunes control of feeding and growth in neonates

    Juliane Glaser, Julian Iranzo ... Deborah Bourc'his
    Zdbf2 is a paternally expressed gene that is mainly expressed in the hypothalamus and promotes appetite and body weight gain in neonates.

    A neuroepithelial wave of BMP signalling drives anteroposterior specification of the tuberal hypothalamus

    Kavitha Chinnaiya, Sarah Burbridge ... Marysia Placzek
    Fate-mapping, combined with gain- and loss-of-function approaches, reveal the role of BMP signalling in the spatio-temporal development of the tuberal hypothalamus, a critically important brain region.

    CNGA3 acts as a cold sensor in hypothalamic neurons

    Viktor V Feketa, Yury A Nikolaev ... Elena O Gracheva
    CNGA3 is a cold-potentiated ion channel that confers cold sensitivity to mouse hypothalamic neurons, whereas CNGA3 from hibernating ground squirrels is cold-insensitive.

    Chemo- and optogenetic activation of hypothalamic Foxb1-expressing neurons and their terminal endings in the rostral-dorsolateral PAG leads to tachypnea, bradycardia, and immobility

    Reto B Cola, Diana M Roccaro-Waldmeyer ... Marco R Celio
    Foxb1-expressing hypothalamic neurons in the parvafox nucleus and the dorsal premammillary nucleus both contribute to behavioral and physiological components associated with defensive behavior.

    State-dependent activity dynamics of hypothalamic stress effector neurons

    Aoi Ichiyama, Samuel Mestern ... Wataru Inoue
    Hypothalamic stress effector neurons rapidly change activity patterns via recurrent inhibition, representing state-dependent activity switch between baseline and elevated stress levels.

    Estrogen receptor alpha in the brain mediates tamoxifen-induced changes in physiology in mice

    Zhi Zhang, Jae Whan Park ... Stephanie M Correa
    Estrogen receptor alpha in the hypothalamus is required for the effects of chronic tamoxifen treament on gene expression, thermoregulation, bone, and movement in mice.
