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.

text: Genetically encoded tags have introduced extensive lines of application from
purification of tagged proteins to their visualization at the single molecular,
cellular, histological and whole-body levels. Combined with other rapidly developing
technologies such as clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR-associated
protein 9 (Cas9) system, proteomics, super-resolution microscopy and proximity
labeling, a large variety of genetically encoded tags have been developed in the
last two decades. In this review, I focus on the current status of tag development
for electron microscopic (EM) visualization of proteins with metal particle labeling.
Compared with conventional immunoelectron microscopy using gold particles, tag-mediated
metal particle labeling has several advantages that could potentially improve
the sensitivity, spatial and temporal resolution, and applicability to a wide
range of proteins of interest (POIs). It may enable researchers to detect single
molecules in situ, allowing the quantitative measurement of absolute numbers and
exact localization patterns of POI in the ultrastructural context. Thus, genetically
encoded tags for EM could revolutionize the field as green fluorescence protein
did for light microscopy, although we still have many challenges to overcome before
reaching this goal.

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.

text: Novelty facilitates formation of memories. The detection of novelty and storage
of contextual memories are both mediated by the hippocampus, yet the mechanisms
that link these two functions remain to be defined. Dentate granule cells (GCs)
of the dorsal hippocampus fire upon novelty exposure forming engrams of contextual
memory. However, their key excitatory inputs from the entorhinal cortex are not
responsive to novelty and are insufficient to make dorsal GCs fire reliably. Here
we uncover a powerful glutamatergic pathway to dorsal GCs from ventral hippocampal
mossy cells (MCs) that relays novelty, and is necessary and sufficient for driving
dorsal GCs activation. Furthermore, manipulation of ventral MCs activity bidirectionally
regulates novelty-induced contextual memory acquisition. Our results show that
ventral MCs activity controls memory formation through an intra-hippocampal interaction
mechanism gated by novelty.

text: In nerve cells the genes encoding for α2δ subunits of voltage-gated calcium
channels have been linked to synaptic functions and neurological disease. Here
we show that α2δ subunits are essential for the formation and organization of
glutamatergic synapses. Using a cellular α2δ subunit triple-knockout/knockdown
model, we demonstrate a failure in presynaptic differentiation evidenced by defective
presynaptic calcium channel clustering and calcium influx, smaller presynaptic
active zones, and a strongly reduced accumulation of presynaptic vesicle-associated
proteins (synapsin and vGLUT). The presynaptic defect is associated with the downscaling
of postsynaptic AMPA receptors and the postsynaptic density. The role of α2δ isoforms
as synaptic organizers is highly redundant, as each individual α2δ isoform can
rescue presynaptic calcium channel trafficking and expression of synaptic proteins.
Moreover, α2δ-2 and α2δ-3 with mutated metal ion-dependent adhesion sites can
fully rescue presynaptic synapsin expression but only partially calcium channel
trafficking, suggesting that the regulatory role of α2δ subunits is independent
from its role as a calcium channel subunit. Our findings influence the current
view on excitatory synapse formation. First, our study suggests that postsynaptic
differentiation is secondary to presynaptic differentiation. Second, the dependence
of presynaptic differentiation on α2δ implicates α2δ subunits as potential nucleation
points for the organization of synapses. Finally, our results suggest that α2δ
subunits act as transsynaptic organizers of glutamatergic synapses, thereby aligning
the synaptic active zone with the postsynaptic density.

text: The synaptic connection from medial habenula (MHb) to interpeduncular nucleus
(IPN) is critical for emotion-related behaviors and uniquely expresses R-type
Ca2+ channels (Cav2.3) and auxiliary GABAB receptor (GBR) subunits, the K+-channel
tetramerization domain-containing proteins (KCTDs). Activation of GBRs facilitates
or inhibits transmitter release from MHb terminals depending on the IPN subnucleus,
but the role of KCTDs is unknown. We therefore examined the localization and function
of Cav2.3, GBRs, and KCTDs in this pathway in mice. We show in heterologous cells
that KCTD8 and KCTD12b directly bind to Cav2.3 and that KCTD8 potentiates Cav2.3
currents in the absence of GBRs. In the rostral IPN, KCTD8, KCTD12b, and Cav2.3
co-localize at the presynaptic active zone. Genetic deletion indicated a bidirectional
modulation of Cav2.3-mediated release by these KCTDs with a compensatory increase
of KCTD8 in the active zone in KCTD12b-deficient mice. The interaction of Cav2.3
with KCTDs therefore scales synaptic strength independent of GBR activation.

text: At the encounter with a novel environment, contextual memory formation is
greatly enhanced, accompanied with increased arousal and active exploration. Although
this phenomenon has been widely observed in animal and human daily life, how the
novelty in the environment is detected and contributes to contextual memory formation
has lately started to be unveiled. The hippocampus has been studied for many decades
for its largely known roles in encoding spatial memory, and a growing body of
evidence indicates a differential involvement of dorsal and ventral hippocampal
divisions in novelty detection. In this brief review article, we discuss the recent
findings of the role of mossy cells in the ventral hippocampal moiety in novelty
detection and put them in perspective with other novelty-related pathways in the
hippocampus. We propose a mechanism for novelty-driven memory acquisition in the
dentate gyrus by the direct projection of ventral mossy cells to dorsal dentate
granule cells. By this projection, the ventral hippocampus sends novelty signals
to the dorsal hippocampus, opening a gate for memory encoding in dentate granule
cells based on information coming from the entorhinal cortex. We conclude that,
contrary to the presently accepted functional independence, the dorsal and ventral
hippocampi cooperate to link the novelty and contextual information, and this
dorso-ventral interaction is crucial for the novelty-dependent memory formation.

text: High-resolution visualization and quantification of membrane proteins contribute
to the understanding of their functions and the roles they play in physiological
and pathological conditions. Sodium dodecyl sulfate-digested freeze-fracture replica
labeling (SDS-FRL) is a powerful electron microscopy method to study quantitatively
the two-dimensional distribution of transmembrane proteins and their tightly associated
proteins. During treatment with SDS, intracellular organelles and proteins not
anchored to the replica are dissolved, whereas integral membrane proteins captured
and stabilized by carbon/platinum deposition remain on the replica. Their intra-
and extracellular domains become exposed on the surface of the replica, facilitating
the accessibility of antibodies and, therefore, providing higher labeling efficiency
than those obtained with other immunoelectron microscopy techniques. In this chapter,
we describe the protocols of SDS-FRL adapted for mammalian brain samples, and
optimization of the SDS treatment to increase the labeling efficiency for quantification
of Cav2.1, the alpha subunit of P/Q-type voltage-dependent calcium channels utilizing
deep learning algorithms.

text: The molecular anatomy of synapses defines their characteristics in transmission
and plasticity. Precise measurements of the number and distribution of synaptic
proteins are important for our understanding of synapse heterogeneity within and
between brain regions. Freeze–fracture replica immunogold electron microscopy
enables us to analyze them quantitatively on a two-dimensional membrane surface.
Here, we introduce Darea software, which utilizes deep learning for analysis of
replica images and demonstrate its usefulness for quick measurements of the pre-
and postsynaptic areas, density and distribution of gold particles at synapses
in a reproducible manner. We used Darea for comparing glutamate receptor and calcium
channel distributions between hippocampal CA3-CA1 spine synapses on apical and
basal dendrites, which differ in signaling pathways involved in synaptic plasticity.
We found that apical synapses express a higher density of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic
acid (AMPA) receptors and a stronger increase of AMPA receptors with synaptic
size, while basal synapses show a larger increase in N-methyl-D-aspartate (NMDA)
receptors with size. Interestingly, AMPA and NMDA receptors are segregated within
postsynaptic sites and negatively correlated in density among both apical and
basal synapses. In the presynaptic sites, Cav2.1 voltage-gated calcium channels
show similar densities in apical and basal synapses with distributions consistent
with an exclusion zone model of calcium channel-release site topography.

text: Acute brain slice preparation is a powerful experimental model for investigating
the characteristics of synaptic function in the brain. Although brain tissue is
usually cut at ice-cold temperature (CT) to facilitate slicing and avoid neuronal
damage, exposure to CT causes molecular and architectural changes of synapses.
To address these issues, we investigated ultrastructural and electrophysiological
features of synapses in mouse acute cerebellar slices prepared at ice-cold and
physiological temperature (PT). In the slices prepared at CT, we found significant
spine loss and reconstruction, synaptic vesicle rearrangement and decrease in
synaptic proteins, all of which were not detected in slices prepared at PT. Consistent
with these structural findings, slices prepared at PT showed higher release probability.
Furthermore, preparation at PT allows electrophysiological recording immediately
after slicing resulting in higher detectability of long-term depression (LTD)
after motor learning compared with that at CT. These results indicate substantial
advantages of the slice preparation at PT for investigating synaptic functions
in different physiological conditions.

text: Chemical labeling of proteins with synthetic molecular probes offers the possibility
to probe the functions of proteins of interest in living cells. However, the methods
for covalently labeling targeted proteins using complementary peptide tag-probe
pairs are still limited, irrespective of the versatility of such pairs in biological
research. Herein, we report the new CysHis tag-Ni(II) probe pair for the specific
covalent labeling of proteins. A broad-range evaluation of the reactivity profiles
of the probe and the CysHis peptide tag afforded a tag-probe pair with an optimized
and high labeling selectivity and reactivity. In particular, the labeling specificity
of this pair was notably improved compared to the previously reported one. This
pair was successfully utilized for the fluorescence imaging of membrane proteins
on the surfaces of living cells, demonstrating its potential utility in biological
research.

text: Electron microscopy (EM) is a technology that enables visualization of single
proteins at a nanometer resolution. However, current protein analysis by EM mainly
relies on immunolabeling with gold-particle-conjugated antibodies, which is compromised
by large size of antibody, precluding precise detection of protein location in
biological samples. Here, we develop a specific chemical labeling method for EM
detection of proteins at single-molecular level. Rational design of α-helical
peptide tag and probe structure provided a complementary reaction pair that enabled
specific cysteine conjugation of the tag. The developed chemical labeling with
gold-nanoparticle-conjugated probe showed significantly higher labeling efficiency
and detectability of high-density clusters of tag-fused G protein-coupled receptors
in freeze-fracture replicas compared with immunogold labeling. Furthermore, in
ultrathin sections, the spatial resolution of the chemical labeling was significantly
higher than that of antibody-mediated labeling. These results demonstrate substantial
advantages of the chemical labeling approach for single protein visualization
by EM.
