    Anti-nociceptive action of peripheral mu-opioid receptors by G-beta-gamma protein-mediated inhibition of TRPM3 channels

    Sandeep Dembla et al.
    Pro-nociceptive and pro-inflammatory TRPM3 (transient receptor potential melastatin 3) channels, expressed in somatosensory neurons, are inhibited by activation of Gαi-coupled receptors, such as µ-opioid receptors, in vitro and in vivo.

    Point of View: Predictive regulation and human design

    Peter Sterling
    Why does the human regulatory system, which evolution tuned for small satisfactions, now constantly demand 'more'?

    Sensory Neurons: A new target for G protein signaling

    László Csanády
    G protein-coupled receptor stimulation inhibits TRPM3 channel activity through direct binding of the Gβγ subunit to the channel.

    Formin-like 1 mediates effector T cell trafficking to inflammatory sites to enable T cell-mediated autoimmunity

    Scott B Thompson et al.
    Lymphocyte migration and autoimmunity induction rely on Formin-like 1-mediated actin network remodeling to push the lymphocyte nucleus through restrictive endothelial barriers.

    Different neuronal populations mediate inflammatory pain analgesia by exogenous and endogenous opioids

    Xin-Yan Zhang et al.
    Exogenous opioid analgesia is mediated by MORs expressed in glutamatergic neurons, whereas endogenous opioid analgesia is mediated by MORs expressed in GABAergic neurons.

    Differential accumulation of storage bodies with aging defines discrete subsets of microglia in the healthy brain

    Jeremy Carlos Burns et al.
    Two novel subsets of microglia identified by their unique autofluorescence profiles differ in their subcellular organization, proteomic signatures and in their response to aging and lysosomal dysfunction.

    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.

    Taar1 gene variants have a causal role in methamphetamine intake and response and interact with Oprm1

    Alexandra M Stafford et al.
    The trace amine-associated receptor 1 gene has a causal role in methamphetamine intake and thermal response, and interacts with the mu-opioid receptor gene in its methamphetamine addiction-related effects.

    Synapse-specific opioid modulation of thalamo-cortico-striatal circuits

    William T Birdsong et al.
    By differentially modulating the two major excitatory inputs to the striatum, mu- and delta-opioid receptors regulate the balance between thalamic and cortical inputs to the striatum.

    Inhibition of Transient Receptor Potential Melastatin 3 ion channels by G-protein βγ subunits

    Doreen Badheka et al.
    Electrophysiological experiments, Ca2+ imaging, and behavioral studies in mice identify the TRPM3 ion channel as a novel target of G-protein βγ subunits.
