  text: "GABAB receptor (GBR) activation inhibits neurotransmitter release in axon
    terminals in the brain, except in medial habenula (MHb) terminals, which show
    robust potentiation. However, mechanisms underlying this enigmatic potentiation
    remain elusive. Here, we report that GBR activation on MHb terminals induces an
    activity-dependent transition from a facilitating, tonic to a depressing, phasic
    neurotransmitter release mode. This transition is accompanied by a 4.1-fold increase
    in readily releasable vesicle pool (RRP) size and a 3.5-fold increase of docked
    synaptic vesicles (SVs) at the presynaptic active zone (AZ). Strikingly, the depressing
    phasic release exhibits looser coupling distance than the tonic release. Furthermore,
    the tonic and phasic release are selectively affected by deletion of synaptoporin
    (SPO) and Ca\r\n            <jats:sup>2+</jats:sup>\r\n            -dependent
    activator protein for secretion 2 (CAPS2), respectively. SPO modulates augmentation,
    the short-term plasticity associated with tonic release, and CAPS2 retains the
    increased RRP for initial responses in phasic response trains. The cytosolic protein
    CAPS2 showed a SV-associated distribution similar to the vesicular transmembrane
    protein SPO, and they were colocalized in the same terminals. We developed the
    “Flash and Freeze-fracture” method, and revealed the release of SPO-associated
    vesicles in both tonic and phasic modes and activity-dependent recruitment of
    CAPS2 to the AZ during phasic release, which lasted several minutes. Overall,
    these results indicate that GBR activation translocates CAPS2 to the AZ along
    with the fusion of CAPS2-associated SVs, contributing to persistency of the RRP
    increase. Thus, we identified structural and molecular mechanisms underlying tonic
    and phasic neurotransmitter release and their transition by GBR activation in
    MHb terminals."

  text: Junctions between the endoplasmic reticulum (ER) and the plasma membrane (PM)
    are specialized membrane contacts ubiquitous in eukaryotic cells. Concentration
    of intracellular signaling machinery near ER-PM junctions allows these domains
    to serve critical roles in lipid and Ca2+ signaling and homeostasis. Subcellular
    compartmentalization of protein kinase A (PKA) signaling also regulates essential
    cellular functions, however, no specific association between PKA and ER-PM junctional
    domains is known. Here, we show that in brain neurons type I PKA is directed to
    Kv2.1 channel-dependent ER-PM junctional domains via SPHKAP, a type I PKA-specific
    anchoring protein. SPHKAP association with type I PKA regulatory subunit RI and
    ER-resident VAP proteins results in the concentration of type I PKA between stacked
    ER cisternae associated with ER-PM junctions. This ER-associated PKA signalosome
    enables reciprocal regulation between PKA and Ca2+ signaling machinery to support
    Ca2+ influx and excitation-transcription coupling. These data reveal that neuronal
    ER-PM junctions support a receptor-independent form of PKA signaling driven by
    membrane depolarization and intracellular Ca2+, allowing conversion of information
    encoded in electrical signals into biochemical changes universally recognized
    throughout the cell.

  text: Phosphatidylinositol-4,5-bisphosphate (PI(4,5)P2) plays an essential role
    in neuronal activities through interaction with various proteins involved in signaling
    at membranes. However, the distribution pattern of PI(4,5)P2 and the association
    with these proteins on the neuronal cell membranes remain elusive. In this study,
    we established a method for visualizing PI(4,5)P2 by SDS-digested freeze-fracture
    replica labeling (SDS-FRL) to investigate the quantitative nanoscale distribution
    of PI(4,5)P2 in cryo-fixed brain. We demonstrate that PI(4,5)P2 forms tiny clusters
    with a mean size of ∼1000 nm2 rather than randomly distributed in cerebellar neuronal
    membranes in male C57BL/6J mice. These clusters show preferential accumulation
    in specific membrane compartments of different cell types, in particular, in Purkinje
    cell (PC) spines and granule cell (GC) presynaptic active zones. Furthermore,
    we revealed extensive association of PI(4,5)P2 with CaV2.1 and GIRK3 across different
    membrane compartments, whereas its association with mGluR1α was compartment specific.
    These results suggest that our SDS-FRL method provides valuable insights into
    the physiological functions of PI(4,5)P2 in neurons.

abstract:
- lang: eng
  text: Upon the arrival of action potentials at nerve terminals, neurotransmitters
    are released from synaptic vesicles (SVs) by exocytosis. CaV2.1, 2.2, and 2.3
    are the major subunits of the voltage-gated calcium channel (VGCC) responsible
    for increasing intraterminal calcium levels and triggering SV exocytosis in the
    central nervous system (CNS) synapses. The two-dimensional analysis of CaV2 distributions
    using sodium dodecyl sulfate (SDS)-digested freeze-fracture replica labeling (SDS-FRL)
    has revealed their numbers, densities, and nanoscale clustering patterns in individual
    presynaptic active zones. The variation in these properties affects the coupling
    of VGCCs with calcium sensors on SVs, synaptic efficacy, and temporal precision
    of transmission. In this study, we summarize how the morphological parameters
    of CaV2 distribution obtained using SDS-FRL differ depending on the different
    types of synapses and could correspond to functional properties in synaptic transmission.
