    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.

    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.

    Mechanically stimulated ATP release from murine bone cells is regulated by a balance of injury and repair

    Nicholas Mikolajewicz et al.
    Bone cells exposed to physiological forces release ATP through repairable membrane injury, generating an intercellular signal that conveys the destructive potential of forces and the adaptive capacity of endangered cells.

    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.

    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.

    Activation of astrocytes in hippocampus decreases fear memory through adenosine A1 receptors

    Yulan Li et al.
    A new strategy of memory consolidation disruption based on astrocyte and purinergic signaling, which leads to persistent fear memory attenuation accompanied by reduced fear-related anxiety behavior.

    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.

    A single-cell transcriptomic and anatomic atlas of mouse dorsal raphe Pet1 neurons

    Benjamin W Okaty et al.
    Dorsal raphe Pet1 neurons are molecularly heterogeneous, comprising as many as fourteen distinct subtypes that show biased cell body distributions across dorsal raphe subdomains.

    Vascular control of the CO2/H+-dependent drive to breathe

    Colin M Cleary et al.
    Understanding how loss of CO2/H+ vascular reactivity affects respiratory control may facilitate development of treatments for breathing problems in this population.

    PIP2 depletion promotes TRPV4 channel activity in mouse brain capillary endothelial cells

    Osama F Harraz et al.
    TRPV4 channels in brain capillaries are suppressed by the phosphoinositide PIP2 and activated by receptor agonists implicated in neurovascular coupling.
