    Antagonistic modulation of NPY/AgRP and POMC neurons in the arcuate nucleus by noradrenalin

    Lars Paeger et al.
    The coordinated differential modulation of satiety signaling POMC- and hunger signaling AgRP- neurons in the arcuate nucleus of the hypothalamus assigns an important role to noradrenalin to promote feeding.

    Energy imbalance alters Ca2+ handling and excitability of POMC neurons

    Lars Paeger et al.
    The development of diet-dependent obesity results in the deterioration of calcium homeostasis in pro-opiomelanocortin-expressing neurons and impaired function of the same neurons.

    Insulin regulates POMC neuronal plasticity to control glucose metabolism

    Garron T Dodd et al.
    Feeding and fasting associated alterations in proopiomelanocortin neuronal responses to insulin coordinate glucose metabolism.

    Central Dicer-miR-103/107 controls developmental switch of POMC progenitors into NPY neurons and impacts glucose homeostasis

    Sophie Croizier et al.
    Loss miRNA maturation in proopiomelanocortin (POMC) neurons causes metabolic dysregulation and favors the differentiation of Pomc progenitors into neuropeptide Y neurons, a developmental process that appears to specifically involve miR-103/107.

    POMC neurons expressing leptin receptors coordinate metabolic responses to fasting via suppression of leptin levels

    Alexandre Caron et al.
    A subset of hypothalamic POMC neurons that express leptin receptors control metabolic responses to changing energy availability including regulating blood glucose and leptin levels.

    Arcuate hypothalamic AgRP and putative POMC neurons show opposite changes in spiking across multiple timescales

    Yael Mandelblat-Cerf et al.
    Gradual changes in the firing of specific hypothalamic neurons over many hours signal falling energy levels, while short-lived changes over seconds and minutes signal the availability of food.

    Plasticity of calcium-permeable AMPA glutamate receptors in Pro-opiomelanocortin neurons

    Shigetomo Suyama et al.
    Neurons in the hypothalamus that promote satiety manifest plasticity of their response to the excitatory transmitter, glutamate, by re-organizing the composition of a specific glutamare receptor.

    Phrenic-specific transcriptional programs shape respiratory motor output

    Alicia N Vagnozzi et al.
    Molecular programs regulated by Hox5 transcription factors establish a set of inhibitory inputs onto phrenic motor neurons that control the pattern of respiratory motor output.
