    Activation of the same mGluR5 receptors in the amygdala causes divergent effects on specific versus indiscriminate fear

    Mohammed Mostafizur Rahman et al.
    Activation of the same glutamate receptor in the lateral amygdala gives rise to distinct effects on specific versus indiscriminate fear by modulating intrinsic excitability and synaptic plasticity.

    Oxidative stress induces stem cell proliferation via TRPA1/RyR-mediated Ca2+ signaling in the Drosophila midgut

    Chiwei Xu et al.
    In response to tissue damage, reactive oxygen species can be sensed by cation channels TRPA1/RyR to cause increases of cytosolic Ca2+ in intestinal stem cells, activating Ras/MAPK activity and stimulating stem cell proliferation in Drosophila.

    Wnt- and glutamate-receptors orchestrate stem cell dynamics and asymmetric cell division

    Sergi Junyent et al.
    Receptors for two distinct pathways are linked to choreograph the dynamic interaction of Wnt on the stem cell membrane, which leads to the control of asymmetric cell division.

    Conformational dynamics between transmembrane domains and allosteric modulation of a metabotropic glutamate receptor

    Vanessa A Gutzeit et al.
    Single molecule subunit counting, FRET and electrophysiology experiments reveal that metabotropic glutamate receptor subunits interact and rearrange at the level of the transmembrane domains in response to allosteric modulators.

    Spontaneous neurotransmission signals through store-driven Ca2+ transients to maintain synaptic homeostasis

    Austin L Reese, Ege T Kavalali
    Individual neurons can adjust the strength of their synapses by using spontaneous calcium influx through NMDA receptors to trigger the release of additional calcium from intracellular stores, which can in turn be used to regulate protein synthesis.

    Synapse-specific and compartmentalized expression of presynaptic homeostatic potentiation

    Xiling Li et al.
    Genetic and electrophysiological analyses reveal that the mechanisms orchestrating the induction and expression of homeostatic plasticity are compartmentalized and operate with exquisite specificity on both sides of the synapse.

    USP5/Leon deubiquitinase confines postsynaptic growth by maintaining ubiquitin homeostasis through Ubiquilin

    Chien-Hsiang Wang et al.
    Maintenance of ubiquitin homeostasis is essential for proper control of the size of postsynaptic density and the growth of specialized membrane structure.

    Signalling through AMPA receptors on oligodendrocyte precursors promotes myelination by enhancing oligodendrocyte survival

    Eleni Kougioumtzidou et al.
    Electrically active axons in white matter stimulate their own myelination by releasing glutamate, which signals through AMPA-type glutamate receptors on nearby oligodendrocyte precursors and newly-differentiating oligodendrocytes, enhancing their survival and hence their ability to myelinate.

    A unified computational model for cortical post-synaptic plasticity

    Tuomo Mäki-Marttunen et al.
    Biochemically detailed modelling of pathways leading to post-synaptic plasticity reveals the dependence of neocortical LTP/LTD on the availability of different proteins and stimulation patterns.

    Cocaine-induced endocannabinoid signaling mediated by sigma-1 receptors and extracellular vesicle secretion

    Yoki Nakamura et al.
    Non-synaptic extracellular vesicles may be involved in the release of endogenous cannabinoids in the central nervous system thereby representing a novel mechanism to mediate their effects on synaptic transmission.
