  text: The coupling between Ca2+ channels and release sensors is a key factor defining
    the signaling properties of a synapse. However, the coupling nanotopography at
    many synapses remains unknown, and it is unclear how it changes during development.
    To address these questions, we examined coupling at the cerebellar inhibitory
    basket cell (BC)-Purkinje cell (PC) synapse. Biophysical analysis of transmission
    by paired recording and intracellular pipette perfusion revealed that the effects
    of exogenous Ca2+ chelators decreased during development, despite constant reliance
    of release on P/Q-type Ca2+ channels. Structural analysis by freeze-fracture replica
    labeling (FRL) and transmission electron microscopy (EM) indicated that presynaptic
    P/Q-type Ca2+ channels formed nanoclusters throughout development, whereas docked
    vesicles were only clustered at later developmental stages. Modeling suggested
    a developmental transformation from a more random to a more clustered coupling
    nanotopography. Thus, presynaptic signaling developmentally approaches a point-to-point
    configuration, optimizing speed, reliability, and energy efficiency of synaptic
    transmission.

  text: Neuronal networks in the brain consist of two main types of neuron, glutamatergic
    principal neurons and GABAergic interneurons. Although these interneurons only
    represent 10–20% of the whole population, they mediate feedback and feedforward
    inhibition and are involved in the generation of high-frequency network oscillations.
    A hallmark functional property of GABAergic interneurons, especially of the parvalbumin‑expressing
    (PV+) subtypes, is the speed of signaling at their output synapse across species
    and brain regions. Several molecular and subcellular factors may underlie the
    submillisecond signaling at GABAergic synapses. Such as the selective use of P/Q
    type Ca2+ channels and the tight coupling between Ca2+ channels and Ca2+ sensors
    of exocytosis. However, whether the molecular identity of the release sensor contributes
    to these signaling properties remains unclear. Besides, these interneurons are
    mainly show depression in response to train of stimuli. How could they keep sufficient
    release to control the activity of postsynaptic principal neurons during high
    network activity, is largely elusive. For my Ph.D. work, we firstly examined the
    Ca2+ sensor of exocytosis at the GABAergic basket cell (BC) to Purkinje cell (PC)
    synapse in the cerebellum. Immunolabeling suggested that BC terminals selectively
    expressed synaptotagmin 2 (Syt2), whereas synaptotagmin 1 (Syt1) was enriched
    in excitatory terminals. Genetic elimination of Syt2 reduced action potential-evoked
    release to ~10% compared to the wild-type control, identifying Syt2 as the major
    Ca2+ sensor at BC‑PC synapses. Differential adenovirus-mediated rescue revealed
    Syt2 triggered release with shorter latency and higher temporal precision, and
    mediated faster vesicle pool replenishment than Syt1. Furthermore, deletion of
    Syt2 severely reduced and delayed disynaptic inhibition following parallel fiber
    stimulation. Thus, the selective use of Syt2 as the release sensor at BC–PC synapse
    ensures fast feedforward inhibition in cerebellar microcircuits. Additionally,
    we tested the function of another synaptotagmin member, Syt7, for inhibitory synaptic
    transmission at the BC–PC synapse. Syt7 is thought to be a Ca2+ sensor that mediates
    asynchronous transmitter release and facilitation at synapses. However, it is
    strongly expressed in fast-spiking, PV+ GABAergic interneurons and the output
    synapses of these neurons produce only minimal asynchronous release and show depression
    rather than facilitation. How could Syt7, a facilitation sensor, contribute to
    the depressed inhibitory synaptic transmission needs to be further investigated
    and understood. Our results indicated that at the BC–PC synapse, Syt7 contributes
    to asynchronous release, pool replenishment and facilitation. In combination,
    these three effects ensure efficient transmitter release during high‑frequency
    activity and guarantee frequency independence of inhibition. Taken together, our
    results confirmed that Syt2, which has the fastest kinetic properties among all
    synaptotagmin members, is mainly used by the inhibitory BC‑PC synapse for synaptic
    transmission, contributing to the speed and temporal precision of transmitter
    release. Furthermore, we showed that Syt7, another highly expressed synaptotagmin
    member in the output synapses of cerebellar BCs, is used for ensuring efficient
    inhibitor synaptic transmission during high activity.

  text: 'Synaptotagmin 7 (Syt7) is thought to be a Ca2+ sensor that mediates asynchronous
    transmitter release and facilitation at synapses. However, Syt7 is strongly expressed
    in fast-spiking, parvalbumin-expressing GABAergic interneurons, and the output
    synapses of these neurons produce only minimal asynchronous release and show depression
    rather than facilitation. To resolve this apparent contradiction, we examined
    the effects of genetic elimination of Syt7 on synaptic transmission at the GABAergic
    basket cell (BC)-Purkinje cell (PC) synapse in cerebellum. Our results indicate
    that at the BC-PC synapse, Syt7 contributes to asynchronous release, pool replenishment,
    and facilitation. In combination, these three effects ensure efficient transmitter
    release during high-frequency activity and guarantee frequency independence of
    inhibition. Our results identify a distinct function of Syt7: ensuring the efficiency
    of high-frequency inhibitory synaptic transmission'

  text: Synaptotagmin 7 (Syt7) was originally identified as a slow Ca2+ sensor for
    lysosome fusion, but its function at fast synapses is controversial. The paper
    by Luo and Südhof (2017) in this issue of Neuron shows that at the calyx of Held
    in the auditory brainstem Syt7 triggers asynchronous release during stimulus trains,
    resulting in reliable and temporally precise high-frequency transmission. Thus,
    a slow Ca2+ sensor contributes to the fast signaling properties of the calyx synapse.

  text: Huge body of evidences demonstrated that volatile anesthetics affect the hippocampal
    neurogenesis and neurocognitive functions, and most of them showed impairment
    at anesthetic dose. Here, we investigated the effect of low dose (1.8%) sevoflurane
    on hippocampal neurogenesis and dentate gyrus-dependent learning. Neonatal rats
    at postnatal day 4 to 6 (P4-6) were treated with 1.8% sevoflurane for 6 hours.
    Neurogenesis was quantified by bromodeoxyuridine labeling and electrophysiology
    recording. Four and seven weeks after treatment, the Morris water maze and contextual-fear
    discrimination learning tests were performed to determine the influence on spatial
    learning and pattern separation. A 6-hour treatment with 1.8% sevoflurane promoted
    hippocampal neurogenesis and increased the survival of newborn cells and the proportion
    of immature granular cells in the dentate gyrus of neonatal rats. Sevoflurane-treated
    rats performed better during the training days of the Morris water maze test and
    in contextual-fear discrimination learning test. These results suggest that a
    subanesthetic dose of sevoflurane promotes hippocampal neurogenesis in neonatal
    rats and facilitates their performance in dentate gyrus-dependent learning tasks.
