text: 'Our understanding of the role played by neurotransmitter receptors in the
developing brain has advanced in recent years. The major excitatory and inhibitory
neurotransmitters in the brain, glutamate and GABA, activate both ionotropic (ligand-gated
ion channels) and metabotropic (G protein-coupled) receptors, and are generally
associated with neuronal communication in the mature brain. However, before the
emergence of their role in neurotransmission in adulthood, they also act to influence
earlier developmental events, some of which occur prior to synapse formation:
such as proliferation, migration, differentiation or survival processes during
neural development. To fulfill these actions in the constructing of the nervous
system, different types of glutamate and GABA receptors need to be expressed both
at the right time and at the right place. The identification by molecular cloning
of 16 ionotropic glutamate receptor subunits, eight metabotropic glutamate receptor
subtypes, 21 ionotropic and two metabotropic GABA receptor subunits, some of which
exist in alternatively splice variants, has enriched our appreciation of how molecular
diversity leads to functional diversity in the brain. It now appears that many
different types of glutamate and GABA receptor subunits have prominent expression
in the embryonic and/or postnatal brain, whereas others are mainly present in
the adult brain. Although the significance of this differential expression of
subunits is not fully understood, it appears that the change in subunit composition
is essential for normal development in particular brain regions. This review focuses
on emerging information relating to the expression and role of glutamatergic and
GABAergic neurotransmitter receptors during prenatal and postnatal development.'

text: Hyperpolarization-activated and cyclic nucleotide-gated (HCN) channels are
involved in the control of neuronal excitability and plasticity. In this study,
we used immunoblotting and immunohistochemical techniques to reveal the developmental
expression and subcellular distribution of the HCN1 subunit in the cerebellar
cortex. During postnatal development, the spatio-temporal expression of HCN1 correlated
well with the morphological events occurring during the ontogenesis of cerebellar
interneurons. Using immunoblotting techniques, HCN1 was weakly detected during
the first postnatal week and continued to increase throughout postnatal development,
peaking at postnatal day (P)15. At the light-microscopic level, HCN1 immunoreactivity
was very weak until P7 whereas from P10-12 to adulthood it was strongly detected
in the lower third of the molecular layer and in the Purkinje cell layer. HCN1
was present in axons running through the molecular layer and in the pericellular
basket around Purkinje cells at P12, but in the periaxonal plexus (the pinceau)
surrounding their initial segment only after P15. Using immunofluorescence, HCN1
colocalized with GAD65 and synaptophysin, demonstrating that the subunit was present
in inhibitory axons and axon terminals. At the electron-microscopic level, in
adulthood, HCN1 immunoparticles were detected at postsynaptic sites in basket
and Purkinje cells but most immunoparticles were found at presynaptic sites in
basket cell axons and in terminals. In the axon terminals, the distribution of
HCN1 was relatively uniform along the extrasynaptic plasma membrane; this was
confirmed using quantitative techniques. The present findings suggest that HCN1
channels may provide a significant route for modulating co-ordinated cerebellar
synaptic transmission through basket cells.

text: The number of ionotropic receptors in synapses is an essential factor for
determining the efficacy of fast transmission. We estimated the number of functional
AMPA receptors at single postsynaptic sites by a combination of two-photon uncaging
of glutamate and the nonstationary fluctuation analysis in immature rat Purkinje
cells (PCs), which receive a single type of excitatory input from climbing fibers.
Areas of postsynaptic membrane specialization at the recorded synapses were measured
by reconstruction of serial ultrathin sections. The number of functional AMPA
receptors was proportional to the synaptic area with a density of ∼ 1280 receptors/μm
2. Moreover, highly sensitive freeze-fracture replica labeling revealed a homogeneous
density of immunogold particles for AMPA receptors in synaptic sites (910 ± 36
particles/μm 2) and much lower density in extrasynaptic sites (19 ± 2 particles/μm
2) in the immature PCs. Our results indicate that in this developing synapse,
the efficacy of transmission is determined by the synaptic area.

text: 'Septohippocampal cholinergic neurons play key roles in learning and memory
processes, and in the generation of hippocampal theta rhythm. The range of receptors
for endogenous modulators expressed on these neurons is unclear. Here we describe
GABAB 1a/b receptor (GABABR) and type 1 cannabinoid receptor (CB1R) expression
in rat septal cholinergic [i.e. choline acetyltransferase (ChAT)-positive] cells.
Using double immunofluorescent staining, we found that almost two-thirds of the
cholinergic cells in the rat medial septum were GABABR positive, and that these
cells had significantly larger somata than did GABABR-negative cholinergic neurons.
We detected CB1R labelling in somata after axonal protein transport was blocked
by colchicine. In these animals about one-third of the cholinergic cells were
CB1R positive. These cells again had larger somata than CB1R-negative cholinergic
neurons. The analyses confirmed that the size of GABABR-positive and CB 1R-positive
cholinergic cells were alike, and all CB 1R-positive cholinergic cells were GABABR
positive as well. CB1R-positive cells were invariably ChAT positive. All retrogradely
labelled septohippocampal cholinergic cells were positive for GABABR and at least
half of them also for CB1R. These data shed light on the existence of at least
two cholinergic cell types in the medial septum: one expresses GABABR and CB1R,
has large somata and projects to the hippocampus, whereas the other is negative
for GABABR and CB1R and has smaller somata. The results also suggest that cholinergic
transmission in the hippocampus is fine-tuned by endocannabinoid signalling.'

text: The GABAergic system, a major inhibitory regulator in the central nervous
system, may also play important roles in peripheral nonneuronal tissues and cells.
Recent studies showed that GABAB receptor is expressed in testis and sperm. To
understand the role of the GABAergic system in spermiogenesis, we examined cellular
localization of GABA and GABAB receptor subunits in rat spermatids by immunocytochemistry.
Immunoreactivity for GABA was detected around acrosomal granules of spermatids
during the Golgi and cap phases. GABAB(1) immunoreactivity was observed in the
acrosomal vesicle of spermatids in Golgi phase, and during cap phase, this reactivity
expanded to the entire region of the acrosome covering the nuclear membrane. The
level of reactivity decreased gradually with maturation of spermatids. In contrast,
GABAB(2) immunoreactivity was not observed in spermatids during Golgi phase but
was detected in the equatorial region during cap phase. Both GABA immunoreactivity
and GABAB(2) immunoreactivity were transferred to the residual cytoplasm during
the release of spermatozoa. Electron microscopic immunocytochemistry revealed
that, during cap phase, GABA and GABAB(1) were distributed within the whole acrosomal
vesicle but not in the acrosomal granule. GABAB(2) immunoreactivity was observed
in the narrow space between the inner acrosomal and nuclear membrane and was limited
to the equatorial region of the spermatid head. These results indicate that the
GABAergic system might be involved in regulation of spermiogenesis.

text: We studied neurogliaform neurons in the stratum lacunosum moleculare of the
CA1 hippocampal area. These interneurons have short stellate dendrites and an
extensive axonal arbor mainly located in the stratum lacunosum moleculare. Single-cell
reverse transcription-PCR showed that these neurons were GABAergic and that the
majority expressed mRNA for neuropeptide Y. Most neurogliaform neurons tested
were immunoreactive for α-actinin-2, and many stratum lacunosum moleculare interneurons
coexpressed α-actinin-2 and neuropeptide Y. Neurogliaform neurons received monosynaptic,
DNQX-sensitive excitatory input from the perforant path, and 40 Hz stimulation
of this input evoked EPSCs displaying either depression or initial facilitation,
followed by depression. Paired recordings performed between neurogliaform neurons
showed that 85% of pairs were electrically connected and 70% were also connected
via GABAergic synapses. Injection of sine waveforms into neurons during paired
recordings resulted in transmission of the waveforms through the electrical synapse.
Unitary IPSCs recorded from neurogliaform pairs readily fatigued, had a slow decay,
and had a strong depression of the synaptic response at a 5 Hz stimulation frequency
that was antagonized by the GABA B antagonist (2S)-3-[[(1S)-1-(3,4-dichlorophenyl)ethyl]amino-2-hydroxypropyl](phenylmethyl)
phosphinic acid (CGP55845). The amplitude of the first IPSC during the 5 Hz stimulation
was also increased by CGP55845, suggesting a tonic inhibition of synaptic transmission.
A small unitary GABA B-mediated IPSC could also be detected, providing the first
evidence for such a component between GABAergic interneurons. Electron microscopic
localization of the GABA B1 subunit at neurogliaform synapses revealed the protein
in both presynaptic and postsynaptic membranes. Our data disclose a novel interneuronal
network well suited for modulating the flow of information between the entorhinal
cortex and CA1 hippocampus.

text: Synaptic vesicle release occurs at a specialized membrane domain known as
the presynaptic active zone (AZ). Several membrane proteins are involved in the
vesicle release processes such as docking, priming, and exocytotic fusion. Cytomatrix
at the active zone (CAZ) proteins are structural components of the AZ and are
highly concentrated in it. Localization of other release-related proteins including
target soluble N-ethylmaleimide-sensitive-factor attachment protein receptor (t-SNARE)
proteins, however, has not been well demonstrated in the AZ. Here, we used sodium
dodecyl sulfate-digested freeze-fracture replica labeling (SDS-FRL) to analyze
quantitatively the distribution of CAZ and t-SNARE proteins in the hippocampal
CA3 area. The AZ in replicated membrane was identified by immunolabeling for CAZ
proteins (CAZ-associated structural protein [CAST] and Bassoon). Clusters of immunogold
particles for these proteins were found on the P-face of presynaptic terminals
of the mossy fiber and associational/commissural (AJC) fiber. Co-labeling with
CAST revealed distribution of the t-SNARE proteins syntaxin and synaptosomal-associated
protein of 25 kDa (SNAP-25) in the AZ as well as in the extrasynaptic membrane
surrounding the AZ (SZ). Quantitative analysis demonstrated that the density of
immunoparticles for CAST in the AZ was more than 100 times higher than in the
SZ, whereas that for syntaxin and SNAP-25 was not significantly different between
the AZ and SZ in both the A/C and mossy fiber terminals. These results support
the involvement of the t-SNARE proteins in exocytotic fusion in the AZ and the
role of CAST in specialization of the membrane domain for the AZ.

text: Presynaptic metabotropic glutamate receptors (mGluRs) show a highly selective
expression and subcellular location in nerve terminals modulating neurotransmitter
release. We have demonstrated that alternatively spliced variants of mGluR8, mGluR8a
and mGluR8b, have an overlapping distribution in the hippocampus, and besides
perforant path terminals, they are expressed in the presynaptic active zone of
boutons making synapses selectively with several types of GABAergic interneurons,
primarily in the stratum oriens. Boutons labeled for mGluR8 formed either type
I or type II synapses, and the latter were GABAergic. Some mGluR8-positive boutons
also expressed mGluR7 or vasoactive intestinal polypeptide. Interneurons strongly
immunopositive for the muscarinic M2 or the mGlu1 receptors were the primary targets
of mGluR8-containing terminals in the stratum oriens, but only neurochemically
distinct subsets were innervated by mGluR8-enriched terminals. The majority of
M2-positive neurons were mGluR8 innervated, but a minority, which expresses somatostatin,
was not. Rare neurons coexpressing calretinin and M2 were consistently targeted
by mGluR8-positive boutons. In vivo recording and labeling of an mGluR8-decorated
and strongly M2-positive interneuron revealed a trilaminar cell with complex spike
bursts during theta oscillations and strong discharge during sharp wave/ripple
events. The trilaminar cell had a large projection from the CA1 area to the subiculum
and a preferential innervation of interneurons in the CA1 area in addition to
pyramidal cell somata and dendrites. The postsynaptic interneuron type-specific
expression of the high-efficacy presynaptic mGluR8 in both putative glutamatergic
and in identified GABAergic terminals predicts a role in adjusting the activity
of interneurons depending on the level of network activity.

text: Input-dependent left-right asymmetry of NMDA receptor ε2 (NR2B) subunit allocation
was discovered in hippocampal Schaffer collateral (Sch) and commissural fiber
pyramidal cell synapses (Kawakami et al., 2003). To investigate whether this asymmetrical
ε2 allocation is also related to the types of the postsynaptic cells, we compared
postembedding immunogold labeling for ε2 in left and right Sch synapses on pyramidal
cells and interneurons. To facilitate the detection of ε2 density difference,
we used ε1 (NR2A) knock-out (KO) mice, which have a simplified NMDA receptor subunit
composition. The labeling density for ε2 but not ζ1 (NR1) and subtype 2/3 glutamate
receptor (GluR2/3) in Sch-CA1 pyramidal cell synapses was significantly different
between the left and right hippocampus with opposite directions in strata oriens
and radiatum; the left to right ratio of ε2 labeling density was 1:1.50 in stratum
oriens and 1.44:1 in stratum radiatum. No significant difference, however, was
detected in CA1 stratum radiatum between the left and right Sch-GluR4-positive
(mostly parvalbumin-positive) and Sch-GluR4-negative interneuron synapses. Consistent
with the anatomical asymmetry, the amplitude ratio of NMDA EPSCs to non-NMDA EPSCs
in pyramidal cells was approximately two times larger in right than left stratum
radiatum and vice versa in stratum oriens of ε1 KO mice. Moreover, the amplitude
of long-term potentiation in the Sch-CA1 synapses of left stratum radiatum was
significantly larger than that in the right corresponding synapses. These results
indicate that the asymmetry of ε2 distribution is target cell specific, resulting
in the left-right difference in NMDA receptor content and plasticity in Sch-CA1
pyramidal cell synapses in ε1 KO mice.

text: Previous studies have shown that neurons in the sacral dorsal commissural
nucleus (SDCN) express neurokinin-1 receptor (NK1R) and can be modulated by the
co-release of GABA and glycine (Gly) from single presynaptic terminal. These results
raise the possibility that GABA/Gly-cocontaining terminals might make synaptic
contacts with NK1R-expressing neurons in the SDCN. In order to provide morphological
evidence for this hypothesis, the triple-immunohistochemical studies were performed
in the SDCN. Triple-immunofluorescence histochemical study showed that some axon
terminals in close association with NK1R-immunopositive (NK1R-ip) neurons in the
SDCN were immunopositive for both glutamic acid decarboxylase (GAD) and glycine
transporter 2 (GlyT2). In electron microscopic dual- and triple-immunohistochemistry
for GAD/GlyT2, GAD/NK1R, GlyT2/NK1R, or GAD/GlyT2/NK1R also revealed dually labeled
(GAD/GlyT2-ip) synaptic terminals upon SDCN neurons, as well as GAD- and/or GlyT2-ip
axon terminals in synaptic contact with NK1R-ip SDCN neurons. These results suggested
that some synaptic terminals upon NK1R-expressing SDCN neurons co-released both
GABA and Gly.

text: Enhanced glutamatergic neurotransmission via the subthalamopallidal or subthalamonigral
projection seems crucial for developing parkinsonian motor signs. In the present
study, the possible changes in the expression of metabotropic glutamate receptors
(mGluRs) were examined in the basal ganglia of a primate model for Parkinson's
disease. When the patterns of immunohistochemical localization of mGluRs in monkeys
administered systemically with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)
were analysed in comparison with normal controls, we found that expression of
mGluR1α, but not of other subtypes, was significantly reduced in the internal
and external segments of the globus pallidus and the substantia nigra pars reticulata.
To elucidate the functional role of mGluR1 in the control of pallidal neuron activity,
extracellular unit recordings combined with intrapallidal microinjections of mGluR1-related
agents were then performed in normal and parkinsonian monkeys. In normal awake
conditions, the spontaneous firing rates of neurons in the pallidal complex were
increased by DHPG, a selective agonist of group I mGluRs, whereas they were decreased
by AIDA, a selective antagonist of group I mGluRs, or LY367385, a selective antagonist
of mGluR1. These electrophysiological data strongly indicate that the excitatory
mechanism of pallidal neurons by glutamate is mediated at least partly through
mGluR1. The effects of the mGluR1-related agents on neuronal firing in the internal
pallidal segment became rather obscure after MPTP treatment. Our results suggest
that the specific down-regulation of pallidal and nigral mGluR1 ot in the parkinsonian
state may exert a compensatory action to reverse the overactivity of the subthalamic
nucleus-derived glutamatergic input that is generated in the disease.

by dimensionally reducing d = 6, N = 1 supersymmetric gauge theory with gauge
group U(1) and a single charged hypermultiplet. Using the deformation method and

random potential in the Boltzmann-Grad low density limit. We prove that the phase

weakly to a linear Boltzmann equation. The Boltzmann collision kernel is given
by the full quantum scattering cross-section of the obstacle potential.

text: We present the results of an experimental investigation into the nature and
structure of turbulent pipe flow at moderate Reynolds numbers. A turbulence regeneration
mechanism is identified which sustains a symmetric traveling wave within the flow.
The periodicity of the mechanism allows comparison to the wavelength of numerically
observed exact traveling wave solutions and close agreement is found. The advection
speed of the upstream turbulence laminar interface in the experimental flow is
observed to form a lower bound on the phase velocities of the exact traveling
wave solutions. Overall our observations suggest that the dynamics of the turbulent
flow at moderate Reynolds numbers are governed by unstable nonlinear traveling
waves.

text: Transitional pipe flow is investigated in two different experimental set-ups.
In the first the stability threshold and the initial growth of localized perturbations
are studied. Good agreement is found with an earlier investigation of the transition
threshold. The measurement technique applied in the last part of this study allows
the reconstruction of the streamwise vorticity in a turbulent puff.

text: We present the results of an experimental investigation of the effect of a
magnetic field on the stability of convection in a liquid metal. A rectangular
container of gallium is subjected to a horizontal temperature gradient and a uniform
magnetic field is applied separately in three directions. The magnetic field suppresses
the oscillation most effectively when it is applied in the vertical direction
and is least efficient when applied in the direction of the temperature gradient.
The critical temperature difference required for the onset of oscillations is
found to scale exponentially with the magnitude of the magnetic field for all
three orientations. Comparisons are made with available theory and qualitative
differences are discussed.

text: The plant hormone auxin elicits many specific context-dependent developmental
responses. Auxin promotes degradation of Aux/IAA proteins that prevent transcription
factors of the auxin response factor (ARF) family from regulating auxin-responsive
target genes. Aux/IAAs and ARFs are represented by large gene families in Arabidopsis.
Here we show that stabilization of BDL/IAA12 or its sister protein IAA13 prevents
MP/ARF5-dependent embryonic root formation whereas stabilized SHY2/IAA3 interferes
with seedling growth. Although both bdl and shy2-2 proteins inhibited MP/ARF5-dependent
reporter gene activation, shy2-2 was much less efficient than bdl to interfere
with embryonic root initiation when expressed from the BDL promoter. Similarly,
MP was much more efficient than ARF16 in this process. When expressed from the
SHY2 promoter, both shy2-2 and bdl inhibited cell elongation and auxin-induced
gene expression in the seedling hypocotyl. By contrast, gravitropism and auxin-induced
gene expression in the root, which were promoted by functionally redundant NPH4/ARF7
and ARF19 proteins, were inhibited by shy2-2, but not by bdl protein. Our results
suggest that auxin signals are converted into specific responses by matching pairs
of coexpressed ARF and Aux/IAA proteins.

text: One of the fundamental properties of the immune system is its capacity to
avoid autoimmune diseases. The mechanism underlying this process, known as self-tolerance,
is hitherto unresolved but seems to involve the control of clonal expansion of
autoreactive lymphocytes. This article reviews mathematical modeling of self-tolerance,
addressing two specific hypotheses. The first hypothesis posits that self-tolerance
is mediated by tuning of activation thresholds, which makes autoreactive T lymphocytes
reversibly "anergic" and unable to proliferate. The second hypothesis
posits that the proliferation of autoreactive T lymphocytes is instead controlled
by specific regulatory T lymphocytes. Models representing the population dynamics
of autoreactive T lymphocytes according to these two hypotheses were derived.
For each model we identified how cell density affects tolerance, and predicted
the corresponding phase spaces and bifurcations. We show that the simple induction
of proliferative anergy, as modeled here, has a density dependence that is only
partially compatible with adoptive transfers of tolerance, and that the models
of tolerance mediated by specific regulatory T cells are closer to the observations.

text: In plants, cell polarity is an issue more recurring than in other systems,
because plants, due to their adaptive and flexible development, often change cell
polarity postembryonically according to intrinsic cues and demands of the environment.
Recent findings on the directional movement of the plant signalling molecule auxin
provide a unique connection between individual cell polarity and the establishment
of polarity at the tissue, organ, and whole-plant levels. Decisions about the
subcellular polar targeting of PIN auxin transport components determine the direction
of auxin flow between cells and consequently mediate multiple developmental events.
In addition, mutations or chemical interference with PIN-based auxin transport
result in abnormal cell divisions. Thus, the complicated links between cell polarity
establishment, auxin transport, cytoskeleton, and oriented cell divisions now
begin to emerge. Here we review the available literature on the issues of cell
polarity in both plants and animals to extend our understanding on the generation,
maintenance, and transmission of cell polarity in plants.

text: 'One of the mechanisms by which signalling molecules regulate cellular behaviour
is modulating subcellular protein translocation. This mode of regulation is often
based on specialized vesicle trafficking, termed constitutive cycling, which consists
of repeated internalization and recycling of proteins to and from the plasma membrane.
No such mechanism of hormone action has been shown in plants although several
proteins, including the PIN auxin efflux facilitators, exhibit constitutive cycling.
Here we show that a major regulator of plant development, auxin, inhibits endocytosis.
This effect is specific to biologically active auxins and requires activity of
the Calossin-like protein BIG. By inhibiting the internalization step of PIN constitutive
cycling, auxin increases levels of PINs at the plasma membrane. Concomitantly,
auxin promotes its own efflux from cells by a vesicle-trafficking-dependent mechanism.
Furthermore, asymmetric auxin translocation during gravitropism is correlated
with decreased PIN internalization. Our data imply a previously undescribed mode
of plant hormone action: by modulating PIN protein trafficking, auxin regulates
PIN abundance and activity at the cell surface, providing a mechanism for the
feedback regulation of auxin transport.'
