    Purinergic signaling in cochlear supporting cells reduces hair cell excitability by increasing the extracellular space

    Travis A Babola et al.
    Supporting cells in the cochlea change their shape in response to purinergic receptor activation, which influences hair cell excitability by altering potassium redistribution in the extracellular space.

    Astrocytes contribute to synapse elimination via type 2 inositol 1,4,5-trisphosphate receptor-dependent release of ATP

    Junhua Yang et al.
    Astrocytes regulate the pruning of excitatory synapses during early life through ATP signaling.

    Purinergic regulation of vascular tone in the retrotrapezoid nucleus is specialized to support the drive to breathe

    Virginia E Hawkins et al.
    CO2/H+-dependent purinergic signaling by astrocytes provides specialized control of vascular tone in a brainstem respiratory center in a manner that contributes to respiratory behavior.

    Connexin-43-dependent ATP release mediates macrophage activation during sepsis

    Michel Dosch et al.
    Autocrine activation of macrophages is modulated by Connexin-43-mediated ATP release in response to TLR-4 and -2 agonists in a P2Y1-dependent manner, ultimately determining sepsis survival.

    Keratinocytes contribute to normal cold and heat sensation

    Katelyn E Sadler et al.
    Purinergic keratinocyte-to-sensory neuron signaling is a ubiquitous amplification mechanism that is required for normal mechanical, cold, and heat sensation in vivo.

    Keratinocytes mediate innocuous and noxious touch via ATP-P2X4 signaling

    Francie Moehring et al.
    Keratinocytes are critical for normal innocuous and noxious touch through their mechanically evoked ATP release and subsequent signaling to P2X4 channels on sensory neurons.

    A Gs-coupled purinergic receptor boosts Ca2+ influx and vascular contractility during diabetic hyperglycemia

    Maria Paz Prada et al.
    A multi-pronged approach shows that a Gs-coupled purinergic receptor is a sensor for glucose-mediated, PKA-dependent potentiation of vascular L-type calcium channels and vasoconstriction.

    Somatostatin-expressing parafacial neurons are CO2/H+ sensitive and regulate baseline breathing

    Colin M Cleary et al.
    Cellular and chemogenetic approaches identify a novel mode of chemotransduction involving regulation of basal breathing by CO2/H+-dependent disinhibition.
