text: Mapping the complex and dense arrangement of cells and their connectivity
in brain tissue demands nanoscale spatial resolution imaging. Super-resolution
optical microscopy excels at visualizing specific molecules and individual cells
but fails to provide tissue context. Here we developed Comprehensive Analysis
of Tissues across Scales (CATS), a technology to densely map brain tissue architecture
from millimeter regional to nanometer synaptic scales in diverse chemically fixed
brain preparations, including rodent and human. CATS uses fixation-compatible
extracellular labeling and optical imaging, including stimulated emission depletion
or expansion microscopy, to comprehensively delineate cellular structures. It
enables three-dimensional reconstruction of single synapses and mapping of synaptic
connectivity by identification and analysis of putative synaptic cleft regions.
Applying CATS to the mouse hippocampal mossy fiber circuitry, we reconstructed
and quantified the synaptic input and output structure of identified neurons.
We furthermore demonstrate applicability to clinically derived human tissue samples,
including formalin-fixed paraffin-embedded routine diagnostic specimens, for visualizing
the cellular architecture of brain tissue in health and disease.

text: Poxviruses are among the largest double-stranded DNA viruses, with members
such as variola virus, monkeypox virus and the vaccination strain vaccinia virus
(VACV). Knowledge about the structural proteins that form the viral core has remained
sparse. While major core proteins have been annotated via indirect experimental
evidence, their structures have remained elusive and they could not be assigned
to individual core features. Hence, which proteins constitute which layers of
the core, such as the palisade layer and the inner core wall, has remained enigmatic.
Here we show, using a multi-modal cryo-electron microscopy (cryo-EM) approach
in combination with AlphaFold molecular modeling, that trimers formed by the cleavage
product of VACV protein A10 are the key component of the palisade layer. This
allows us to place previously obtained descriptions of protein interactions within
the core wall into perspective and to provide a detailed model of poxvirus core
architecture. Importantly, we show that interactions within A10 trimers are likely
generalizable over members of orthopox- and parapoxviruses.

text: Cell division in all domains of life requires the orchestration of many proteins,
but in Archaea most of the machinery remains poorly characterized. Here we investigate
the FtsZ-based cell division mechanism in Haloferax volcanii and find proteins
containing photosynthetic reaction centre (PRC) barrel domains that play an essential
role in archaeal cell division. We rename these proteins cell division protein
B 1 (CdpB1) and CdpB2. Depletions and deletions in their respective genes cause
severe cell division defects, generating drastically enlarged cells. Fluorescence
microscopy of tagged FtsZ1, FtsZ2 and SepF in CdpB1 and CdpB2 mutant strains revealed
an unusually disordered divisome that is not organized into a distinct ring-like
structure. Biochemical analysis shows that SepF forms a tripartite complex with
CdpB1/2 and crystal structures suggest that these two proteins might form filaments,
possibly aligning SepF and the FtsZ2 ring during cell division. Overall our results
indicate that PRC-domain proteins play essential roles in FtsZ-based cell division
in Archaea.

text: The extracellular matrix (ECM) serves as a scaffold for cells and plays an
essential role in regulating numerous cellular processes, including cell migration
and proliferation. Due to limitations in specimen preparation for conventional
room-temperature electron microscopy, we lack structural knowledge on how ECM
components are secreted, remodeled, and interact with surrounding cells. We have
developed a 3D-ECM platform compatible with sample thinning by cryo-focused ion
beam milling, the lift-out extraction procedure, and cryo-electron tomography.
Our workflow implements cell-derived matrices (CDMs) grown on EM grids, resulting
in a versatile tool closely mimicking ECM environments. This allows us to visualize
ECM for the first time in its hydrated, native context. Our data reveal an intricate
network of extracellular fibers, their positioning relative to matrix-secreting
cells, and previously unresolved structural entities. Our workflow and results
add to the structural atlas of the ECM, providing novel insights into its secretion
and assembly.

text: Root gravitropic bending represents a fundamental aspect of terrestrial plant
physiology. Gravity is perceived by sedimentation of starch-rich plastids (statoliths)
to the bottom of the central root cap cells. Following gravity perception, intercellular
auxin transport is redirected downwards leading to an asymmetric auxin accumulation
at the lower root side causing inhibition of cell expansion, ultimately resulting
in downwards bending. How gravity-induced statoliths repositioning is translated
into asymmetric auxin distribution remains unclear despite PIN auxin efflux carriers
and the Negative Gravitropic Response of roots (NGR) proteins polarize along statolith
sedimentation, thus providing a plausible mechanism for auxin flow redirection.
In this study, using a functional NGR1-GFP construct, we visualized the NGR1 localization
on the statolith surface and plasma membrane (PM) domains in close proximity to
the statoliths, correlating with their movements. We determined that NGR1 binding
to these PM domains is indispensable for NGR1 functionality and relies on cysteine
acylation and adjacent polybasic regions as well as on lipid and sterol PM composition.
Detailed timing of the early events following graviperception suggested that both
NGR1 repolarization and initial auxin asymmetry precede the visible PIN3 polarization.
This discrepancy motivated us to unveil a rapid, NGR-dependent translocation of
PIN-activating AGCVIII kinase D6PK towards lower PMs of gravity-perceiving cells,
thus providing an attractive model for rapid redirection of auxin fluxes following
gravistimulation.

text: Plant morphogenesis relies exclusively on oriented cell expansion and division.
Nonetheless, the mechanism(s) determining division plane orientation remain elusive.
Here, we studied tissue healing after laser-assisted wounding in roots of Arabidopsis
thaliana and uncovered how mechanical forces stabilize and reorient the microtubule
cytoskeleton for the orientation of cell division. We identified that root tissue
functions as an interconnected cell matrix, with a radial gradient of tissue extendibility
causing predictable tissue deformation after wounding. This deformation causes
instant redirection of expansion in the surrounding cells and reorientation of
microtubule arrays, ultimately predicting cell division orientation. Microtubules
are destabilized under low tension, whereas stretching of cells, either through
wounding or external aspiration, immediately induces their polymerization. The
higher microtubule abundance in the stretched cell parts leads to the reorientation
of microtubule arrays and, ultimately, informs cell division planes. This provides
a long-sought mechanism for flexible re-arrangement of cell divisions by mechanical
forces for tissue reconstruction and plant architecture.

text: Clathrin-mediated endocytosis (CME) is vital for the regulation of plant growth
and development by controlling plasma membrane protein composition and cargo uptake.
CME relies on the precise recruitment of regulators for vesicle maturation and
release. Homologues of components of mammalian vesicle scission are strong candidates
to be part of the scission machinery in plants, but the precise roles of these
proteins in this process are not fully understood. Here, we characterised the
roles of Plant Dynamin-Related Proteins 2 (DRP2s) and SH3-domain containing protein
2 (SH3P2), the plant homologue to Dynamins’ recruiters, like Endophilin and Amphiphysin,
in the CME by combining high-resolution imaging of endocytic events in vivo and
characterisation of the purified proteins in vitro. Although DRP2s and SH3P2 arrive
similarly late during CME and physically interact, genetic analysis of the sh3p123
triple-mutant and complementation assays with non-SH3P2-interacting DRP2 variants
suggests that SH3P2 does not directly recruit DRP2s to the site of endocytosis.
These observations imply that despite the presence of many well-conserved endocytic
components, plants have acquired a distinct mechanism for CME.

text: 'There is a growing interest in cost-effective polycrystalline SnSe-based
thermoelectric (TE) materials, which are able to replace the high performance
but mechanically fragile and costly single-crystalline SnSe. In this study, we
present a low-temperature solution-based approach to produce SnSe-PbSe nanocomposites
with outstanding TE performance. Our method involves combining surfactant-free
SnSe particles with oleate-capped PbSe nanocrystals in specific ratios, followed
by thermal annealing and consolidation using spark plasma sintering. These nanocomposites
are characterized by distinct compositional and structural properties that significantly
impact their transport properties. In particular, the addition of oleate-capped
PbSe nanocrystals results in: i) a reduction in the electrostatically adsorbed
Na at the surface of the SnSe particles; ii) a reduction of Sn vacancies due to
alloying with Pb; iii) an increase in grain boundary density; and iv) the formation
of PbSnSe secondary phases. Notably, the SnSe-2.5 %PbSe nanocomposites demonstrate
a 30 % decrease in thermal conductivity compared to that of the SnSe matrix. This
reduction contributes to a maximum figure of merit (zT) of 1.75 at 788 K with
a high average zT value of ca. 1.2 in the medium temperature range of 573–773
K. These values represent one of the highest reported in polycrystalline SnSe
materials, showcasing the potential of our fabricated SnSe-PbSe nanocomposites
for cost-effective TE applications.'

text: 'Cholecystokinin-expressing interneurons (CCKIs) are hypothesized to shape
pyramidal cell-firing patterns and regulate network oscillations and related network
state transitions. To directly probe their role in the CA1 region, we silenced
their activity using optogenetic and chemogenetic tools in mice. Opto-tagged CCKIs
revealed a heterogeneous population, and their optogenetic silencing triggered
wide disinhibitory network changes affecting both pyramidal cells and other interneurons.
CCKI silencing enhanced pyramidal cell burst firing and altered the temporal coding
of place cells: theta phase precession was disrupted, whereas sequence reactivation
was enhanced. Chemogenetic CCKI silencing did not alter the acquisition of spatial
reference memories on the Morris water maze but enhanced the recall of contextual
fear memories and enabled selective recall when similar environments were tested.
This work suggests the key involvement of CCKIs in the control of place-cell temporal
coding and the formation of contextual memories.'

text: Animals rely on compensatory actions to maintain stability and navigate their
environment efficiently. These actions depend on global visual motion cues known
as optic-flow. While the optomotor response has been the traditional focus for
studying optic-flow compensation in insects, its simplicity has been insufficient
to determine the role of the intricate optic-flow processing network involved
in visual course control. Here, we reveal a series of course control behaviours
in Drosophila and link them to specific neural circuits. We show that bilateral
electrical coupling of optic-flow-sensitive neurons in the fly’s lobula plate
are required for a proper course control. This electrical interaction works alongside
chemical synapses within the HS-H2 network to control the dynamics and direction
of turning behaviours. Our findings reveal how insects use bilateral motion cues
for navigation, assigning a new functional significance to the HS-H2 network and
suggesting a previously unknown role for gap junctions in non-linear operations.

text: Transcription-coupled nucleotide excision repair (TC-NER) efficiently eliminates
DNA damage that impedes gene transcription by RNA polymerase II (RNA Pol II).
TC-NER is initiated by the recognition of lesion-stalled RNA Pol II by CSB, which
recruits the CRL4CSA ubiquitin ligase and UVSSA. RNA Pol II ubiquitylation at
RPB1-K1268 by CRL4CSA serves as a critical TC-NER checkpoint, governing RNA Pol
II stability and initiating DNA damage excision by TFIIH recruitment. However,
the precise regulatory mechanisms of CRL4CSA activity and TFIIH recruitment remain
elusive. Here, we reveal human serine/threonine-protein kinase 19 (STK19) as a
TC-NER factor, which is essential for correct DNA damage removal and subsequent
transcription restart. Cryogenic electron microscopy (cryo-EM) studies demonstrate
that STK19 is an integral part of the RNA Pol II-TC-NER complex, bridging CSA,
UVSSA, RNA Pol II, and downstream DNA. STK19 stimulates TC-NER complex stability
and CRL4CSA activity, resulting in efficient RNA Pol II ubiquitylation and correct
UVSSA and TFIIH binding. These findings underscore the crucial role of STK19 as
a core TC-NER component.

text: Hormone perception and signaling pathways have a fundamental regulatory function
in the physiological processes of plants. Cytokinins, a class of plant hormones,
regulate cell division and meristem maintenance. The cytokinin signaling pathway
is well established in the model plant Arabidopsis thaliana. Several negative
feedback mechanisms, tightly controlling cytokinin signaling output, have been
described previously. In this study, we identified a new feedback mechanism executed
through alternative splicing of the cytokinin receptor AHK4/CRE1. A novel splicing
variant named CRE1int7 results from seventh intron retention, introducing a premature
termination codon in the transcript. We showed that CRE1int7 is translated in
planta into a truncated receptor lacking the C-terminal receiver domain essential
for signal transduction. CRE1int7 can bind cytokinin but cannot activate the downstream
cascade. We present a novel negative feedback mechanism of the cytokinin signaling
pathway, facilitated by a decoy receptor that can inactivate canonical cytokinin
receptors via dimerization and compete with them for ligand binding. Ensuring
proper plant growth and development requires precise control of the cytokinin
signaling pathway at several levels. CRE1int7 represents a so-far unknown mechanism
for fine-tuning the cytokinin signaling pathway in Arabidopsis.

text: Poxviruses are large pleomorphic double-stranded DNA viruses that include
well known members such as variola virus, the causative agent of smallpox, Mpox
virus, as well as Vaccinia virus (VACV), which serves as a vaccination strain
for formerly mentioned viruses. VACV is a valuable model for studying large pleomorphic
DNA viruses in general and poxviruses specifically, as many features, such as
core morphology and structural proteins, are well conserved within this family.
Despite decades of research, our understanding of the structural components and
proteins that comprise the poxvirus core in mature virions remains limited. Although
major core proteins were identified via indirect experimental evidence, the core's
complexity, with its large size, structure and number of involved proteins, has
hindered efforts to achieve high-resolution insights and to define the roles of
the individual proteins. The specific protein composition of the core's individual
layers, including the palisade layer and the inner core wall, has remained unclear.
In this study, we have merged multiple approaches, including single particle cryo
electron microscopy of purified virus cores, cryo-electron tomography and subtomogram
averaging of mature virions and molecular modeling to elucidate the structural
determinants of the VACV core. Due to the lack of experimentally derived structures,
either in situ or reconstituted in vitro, we used Alphafold to predict models
of the putative major core protein candidates, A10, 23k, A3, A4, and L4. Our results
show that the VACV core is composed of several layers with varying local symmetries,
forming more intricate interactions than observed previously. This allowed us
to identify several molecular building blocks forming the viral core lattice.
In particular, we identified trimers of protein A10 as a major core structure
that forms the palisade layer of the viral core. Additionally, we revealed that
six petals of a flower shaped core pore within the core wall are composed of A10
trimers. Furthermore, we obtained a cryo-EM density for the inner core wall that
could potentially accommodate an A3 dimer. Integrating descriptions of protein
interactions from previous studies enabled us to provide a detailed structural
model of the poxvirus core wall, and our findings indicate that the interactions
within A10 trimers are likely consistent across orthopox- and parapoxviruses.
This combined application of cryo-SPA and cryo-ET can help overcome obstacles
in studying complex virus structures in the future, including their key assembly
proteins, interactions, and the formation into a core lattice. Our work provides
important fundamental new insights into poxvirus core architecture, also considering
the recent re-emergence of poxviruses.

text: "Understanding the relationship between a given phenotype and its underlying
genotype or genotypes is one of the most pressing challenges of biology, as it
lies at the heart of not only basic understanding of evolutionary theory, but
also of practical applications in medicine and bioengineering. Understanding this
relationship is complicated by the ubiquitous phenomenon of epistasis, wherein
mutation effects are dependent on their genetic context. Fitness landscapes —
representations of phenotype as a function of genotype — are being increasingly
used as a tool to study the effects and interactions of thousands of mutations,
but are experimentally limited to exploring a small fraction of a protein’s theoretical
sequence space. Furthermore, not all regions of said sequence space are necessarily
equally informative. Thus, gene selection for landscape surveys should be carefully
considered in order to maximize the usable output of necessarily limited data.\r\n\r\nIn
this work, we analyzed the fitness landscapes of orthologous green fluorescent
proteins from four different species, by systematically measuring the phenotype,
fluorescence, of tens of thousands of mutant genotypes from each protein. These
landscapes were highly heterogeneous, with some genes being mutationally robust
and displaying epistasis only rarely, and others being highly epistatic and mutationally
fragile. We used this data to train machine learning models to predict fluorescence
from genotype. Although the training data contained almost exclusively genotypes
with less than 3% sequence divergence from the original wild-type sequences, we
were able to create novel, functional genotypes with up to 20% sequence divergence.
Counterintuitively however, genes with high mutational robustness and rare epistasis
were more difficult to introduce large numbers of mutations into, not less. This
represents the first study of large-scale fitness landscapes of a protein family,
and provides insights into how to approach future landscape surveys and their
applications in novel protein design."

text: Thermoelectric materials convert heat into electricity, with a broad range
of applications near room temperature (RT). However, the library of RT high-performance
materials is limited. Traditional high-temperature synthetic methods constrain
the range of materials achievable, hindering the ability to surpass crystal structure
limitations and engineer defects. Here, a solution-based synthetic approach is
introduced, enabling RT synthesis of powders and exploration of densification
at lower temperatures to influence the material's microstructure. The approach
is exemplified by Ag2Se, an n-type alternative to bismuth telluride. It is demonstrated
that the concentration of Ag interstitials, grain boundaries, and dislocations
are directly correlated to the sintering temperature, and achieve a figure of
merit of 1.1 from RT to 100 °C after optimization. Moreover, insights into and
resolve Ag2Se's challenges are provided, including stoichiometry issues leading
to irreproducible performances. This work highlights the potential of RT solution
synthesis in expanding the repertoire of high-performance thermoelectric materials
for practical applications.

text: Multiplexed fluorescence microscopy imaging is widely used in biomedical applications.
However, simultaneous imaging of multiple fluorophores can result in spectral
leaks and overlapping, which greatly degrades image quality and subsequent analysis.
Existing popular spectral unmixing methods are mainly based on computational intensive
linear models and the performance is heavily dependent on the reference spectra,
which may greatly preclude its further applications. In this paper, we propose
a deep learning-based blindly spectral unmixing method, termed AutoUnmix, to imitate
the physical spectral mixing process. A tranfer learning framework is further
devised to allow our AutoUnmix adapting to a variety of imaging systems without
retraining the network. Our proposed method has demonstrated real-time unmixing
capabilities, surpassing existing methods by up to 100-fold in terms of unmixing
speed. We further validate the reconstruction performance on both synthetic datasets
and biological samples. The unmixing results of AutoUnmix achieve a highest SSIM
of 0.99 in both three- and four-color imaging, with nearly up to 20% higher than
other popular unmixing methods. Due to the desirable property of data independency
and superior blind unmixing performance, we believe AutoUnmix is a powerful tool
to study the interaction process of different organelles labeled by multiple fluorophores.

abstract:
- lang: eng
text: The human brain has remarkable computational power. It generates sophisticated
behavioral sequences, stores engrams over an individual’s lifetime, and produces
higher cognitive functions up to the level of consciousness. However, so little
of our neuroscience knowledge covers the human brain, and it remains unknown whether
this organ is truly unique, or is a scaled version of the extensively studied
rodent brain. To address this fundamental question, we determined the cellular,
synaptic, and connectivity rules of the hippocampal CA3 recurrent circuit using
multicellular patch clamp-recording. This circuit is the largest autoassociative
network in the brain, and plays a key role in memory and higher-order computations
such as pattern separation and pattern completion. We demonstrate that human hippocampal
CA3 employs sparse connectivity, in stark contrast to neocortical recurrent networks.
Connectivity sparsifies from rodents to humans, providing a circuit architecture
that maximizes associational power. Unitary synaptic events at human CA3–CA3 synapses
showed both distinct species-specific and circuit-dependent properties, with high
reliability, unique amplitude precision, and long integration times. We also identify
differential scaling rules between hippocampal pathways from rodents to humans,
with a moderate increase in the convergence of CA3 inputs per cell, but a marked
increase in human mossy fiber innervation. Anatomically guided full-scale modeling
suggests that the human brain’s sparse connectivity, expanded neuronal number,
and reliable synaptic signaling combine to enhance the associative memory storage
capacity of CA3. Together, our results reveal unique rules of connectivity and
synaptic signaling in the human hippocampus, demonstrating the absolute necessity
of human brain research and beginning to unravel the remarkable performance of
our autoassociative memory circuits.
