text: Muskelin (Mkln1) is implicated in neuronal function, regulating plasma membrane
receptor trafficking. However, its influence on intrinsic brain activity and corresponding
behavioral processes remains unclear. Here we show that murine Mkln1
knockout causes non-habituating locomotor activity, increased exploratory drive,
and decreased locomotor response to amphetamine. Muskelin deficiency impairs social
novelty detection while promoting the retention of spatial reference memory and
fear extinction recall. This is strongly mirrored in either weaker or stronger
resting-state functional connectivity between critical circuits mediating locomotor
exploration and cognition. We show that Mkln1 deletion
alters dendrite branching and spine structure, coinciding with enhanced AMPAR-mediated
synaptic transmission but selective impairment in synaptic potentiation maintenance.
We identify muskelin at excitatory synapses and highlight its role in regulating
dendritic spine actin stability. Our findings point to aberrant spine actin modulation
and changes in glutamatergic synaptic function as critical mechanisms that contribute
to the neurobehavioral phenotype arising from Mkln1
ablation.

text: The question of how RNA, as the principal carrier of genetic information evolved
is fundamentally important for our understanding of the origin of life. The RNA
molecule is far too complex to have formed in one evolutionary step, suggesting
that ancestral proto-RNAs (first ancestor of RNA) may have existed, which evolved
over time into the RNA of today. Here we show that isoxazole nucleosides, which
are quickly formed from hydroxylamine, cyanoacetylene, urea and ribose, are plausible
precursors for RNA. The isoxazole nucleoside can rearrange within an RNA-strand
to give cytidine, which leads to an increase of pairing stability. If the proto-RNA
contains a canonical seed-nucleoside with defined stereochemistry, the seed-nucleoside
can control the configuration of the anomeric center that forms during the in-RNA
transformation. The results demonstrate that RNA could have emerged from evolutionarily
primitive precursor isoxazole ribosides after strand formation.

text: Biological systems are the sum of their dynamic three-dimensional (3D) parts.
Therefore, it is critical to study biological structures in 3D and at high resolution
to gain insights into their physiological functions. Electron microscopy of metal
replicas of unroofed cells and isolated organelles has been a key technique to
visualize intracellular structures at nanometer resolution. However, many of these
methods require specialized equipment and personnel to complete them. Here, we
present novel accessible methods to analyze biological structures in unroofed
cells and biochemically isolated organelles in 3D and at nanometer resolution,
focusing on Arabidopsis clathrin-coated vesicles (CCVs). While CCVs are essential
trafficking organelles, their detailed structural information is lacking due to
their poor preservation when observed via classical electron microscopy protocols
experiments. First, we establish a method to visualize CCVs in unroofed cells
using scanning transmission electron microscopy tomography, providing sufficient
resolution to define the clathrin coat arrangements. Critically, the samples are
prepared directly on electron microscopy grids, removing the requirement to use
extremely corrosive acids, thereby enabling the use of this method in any electron
microscopy lab. Secondly, we demonstrate that this standardized sample preparation
allows the direct comparison of isolated CCV samples with those visualized in
cells. Finally, to facilitate the high-throughput and robust screening of metal
replicated samples, we provide a deep learning analysis method to screen the “pseudo
3D” morphologies of CCVs imaged with 2D modalities. Collectively, our work establishes
accessible ways to examine the 3D structure of biological samples and provide
novel insights into the structure of plant CCVs.

text: 'Theoretical foundations of chaos have been predominantly laid out for finite-dimensional
dynamical systems, such as the three-body problem in classical mechanics and the
Lorenz model in dissipative systems. In contrast, many real-world chaotic phenomena,
e.g., weather, arise in systems with many (formally infinite) degrees of freedom,
which limits direct quantitative analysis of such systems using chaos theory.
In the present work, we demonstrate that the hydrodynamic pilot-wave systems offer
a bridge between low- and high-dimensional chaotic phenomena by allowing for a
systematic study of how the former connects to the latter. Specifically, we present
experimental results, which show the formation of low-dimensional chaotic attractors
upon destabilization of regular dynamics and a final transition to high-dimensional
chaos via the merging of distinct chaotic regions through a crisis bifurcation.
Moreover, we show that the post-crisis dynamics of the system can be rationalized
as consecutive scatterings from the nonattracting chaotic sets with lifetimes
following exponential distributions. '

text: The AAA-ATPase Drg1 is a key factor in eukaryotic ribosome biogenesis that
initiates cytoplasmic maturation of the large ribosomal subunit. Drg1 releases
the shuttling maturation factor Rlp24 from pre-60S particles shortly after nuclear
export, a strict requirement for downstream maturation. The molecular mechanism
of release remained elusive. Here, we report a series of cryo-EM structures that
captured the extraction of Rlp24 from pre-60S particles by Saccharomyces cerevisiae
Drg1. These structures reveal that Arx1 and the eukaryote-specific rRNA expansion
segment ES27 form a joint docking platform that positions Drg1 for efficient extraction
of Rlp24 from the pre-ribosome. The tips of the Drg1 N domains thereby guide the
Rlp24 C terminus into the central pore of the Drg1 hexamer, enabling extraction
by a hand-over-hand translocation mechanism. Our results uncover substrate recognition
and processing by Drg1 step by step and provide a comprehensive mechanistic picture
of the conserved modus operandi of AAA-ATPases.

text: 5-Carboxycytosine (5caC) is a rare epigenetic modification found in nucleic
acids of all domains of life. Despite its sparse genomic abundance, 5caC is presumed
to play essential regulatory roles in transcription, maintenance and base-excision
processes in DNA. In this work, we utilize nuclear magnetic resonance (NMR) spectroscopy
to address the effects of 5caC incorporation into canonical DNA strands at multiple
pH and temperature conditions. Our results demonstrate that 5caC has a pH-dependent
global destabilizing and a base-pair mobility enhancing local impact on dsDNA,
albeit without any detectable influence on the ground-state B-DNA structure. Measurement
of hybridization thermodynamics and kinetics of 5caC-bearing DNA duplexes highlighted
how acidic environment (pH 5.8 and 4.7) destabilizes the double-stranded structure
by ∼10–20 kJ mol–1 at 37 °C when compared to the same sample at neutral pH. Protonation
of 5caC results in a lower activation energy for the dissociation process and
a higher barrier for annealing. Studies on conformational exchange on the microsecond
time scale regime revealed a sharply localized base-pair motion involving exclusively
the modified site and its immediate surroundings. By direct comparison with canonical
and 5-formylcytosine (5fC)-edited strands, we were able to address the impact
of the two most oxidized naturally occurring cytosine derivatives in the genome.
These insights on 5caC’s subtle sensitivity to acidic pH contribute to the long-standing
questions of its capacity as a substrate in base excision repair processes and
its purpose as an independent, stable epigenetic mark.

text: In eukaryotes, clathrin-coated vesicles (CCVs) facilitate the internalization
of material from the cell surface as well as the movement of cargo in post-Golgi
trafficking pathways. This diversity of functions is partially provided by multiple
monomeric and multimeric clathrin adaptor complexes that provide compartment and
cargo selectivity. The adaptor-protein assembly polypeptide-1 (AP-1) complex operates
as part of the secretory pathway at the trans-Golgi network (TGN), while the AP-2
complex and the TPLATE complex jointly operate at the plasma membrane to execute
clathrin-mediated endocytosis. Key to our further understanding of clathrin-mediated
trafficking in plants will be the comprehensive identification and characterization
of the network of evolutionarily conserved and plant-specific core and accessory
machinery involved in the formation and targeting of CCVs. To facilitate these
studies, we have analyzed the proteome of enriched TGN/early endosome-derived
and endocytic CCVs isolated from dividing and expanding suspension-cultured Arabidopsis
(Arabidopsis thaliana) cells. Tandem mass spectrometry analysis results were validated
by differential chemical labeling experiments to identify proteins co-enriching
with CCVs. Proteins enriched in CCVs included previously characterized CCV components
and cargos such as the vacuolar sorting receptors in addition to conserved and
plant-specific components whose function in clathrin-mediated trafficking has
not been previously defined. Notably, in addition to AP-1 and AP-2, all subunits
of the AP-4 complex, but not AP-3 or AP-5, were found to be in high abundance
in the CCV proteome. The association of AP-4 with suspension-cultured Arabidopsis
CCVs is further supported via additional biochemical data.

text: Immune cells are constantly on the move through multicellular organisms to
explore and respond to pathogens and other harmful insults. While moving, immune
cells efficiently traverse microenvironments composed of tissue cells and extracellular
fibers, which together form complex environments of various porosity, stiffness,
topography, and chemical composition. In this protocol we describe experimental
procedures to investigate immune cell migration through microenvironments of heterogeneous
porosity. In particular, we describe micro-channels, micro-pillars, and collagen
networks as cell migration paths with alternative pore size choices. Employing
micro-channels or micro-pillars that divide at junctions into alternative paths
with initially differentially sized pores allows us to precisely (1) measure the
cellular translocation time through these porous path junctions, (2) quantify
the cellular preference for individual pore sizes, and (3) image cellular components
like the nucleus and the cytoskeleton. This reductionistic experimental setup
thus can elucidate how immune cells perform decisions in complex microenvironments
of various porosity like the interstitium. The setup further allows investigation
of the underlying forces of cellular squeezing and the consequences of cellular
deformation on the integrity of the cell and its organelles. As a complementary
approach that does not require any micro-engineering expertise, we describe the
usage of three-dimensional collagen networks with different pore sizes. Whereas
we here focus on dendritic cells as a model for motile immune cells, the described
protocols are versatile as they are also applicable for other immune cell types
like neutrophils and non-immune cell types such as mesenchymal and cancer cells.
In summary, we here describe protocols to identify the mechanisms and principles
of cellular probing, decision making, and squeezing during cellular movement through
microenvironments of heterogeneous porosity.

text: 'Lymph nodes (LNs) comprise two main structural elements: fibroblastic reticular
cells that form dedicated niches for immune cell interaction and capsular fibroblasts
that build a shell around the organ. Immunological challenge causes LNs to increase
more than tenfold in size within a few days. Here, we characterized the biomechanics
of LN swelling on the cellular and organ scale. We identified lymphocyte trapping
by influx and proliferation as drivers of an outward pressure force, causing fibroblastic
reticular cells of the T-zone (TRCs) and their associated conduits to stretch.
After an initial phase of relaxation, TRCs sensed the resulting strain through
cell matrix adhesions, which coordinated local growth and remodeling of the stromal
network. While the expanded TRC network readopted its typical configuration, a
massive fibrotic reaction of the organ capsule set in and countered further organ
expansion. Thus, different fibroblast populations mechanically control LN swelling
in a multitier fashion.'

text: Tension of the actomyosin cell cortex plays a key role in determining cell–cell
contact growth and size. The level of cortical tension outside of the cell–cell
contact, when pulling at the contact edge, scales with the total size to which
a cell–cell contact can grow [J.-L. Maître et al., Science 338, 253–256 (2012)].
Here, we show in zebrafish primary germ-layer progenitor cells that this monotonic
relationship only applies to a narrow range of cortical tension increase and that
above a critical threshold, contact size inversely scales with cortical tension.
This switch from cortical tension increasing to decreasing progenitor cell–cell
contact size is caused by cortical tension promoting E-cadherin anchoring to the
actomyosin cytoskeleton, thereby increasing clustering and stability of E-cadherin
at the contact. After tension-mediated E-cadherin stabilization at the contact
exceeds a critical threshold level, the rate by which the contact expands in response
to pulling forces from the cortex sharply drops, leading to smaller contacts at
physiologically relevant timescales of contact formation. Thus, the activity of
cortical tension in expanding cell–cell contact size is limited by tension-stabilizing
E-cadherin–actin complexes at the contact.

text: Kelvin probe force microscopy (KPFM) is a powerful tool for studying contact
electrification (CE) at the nanoscale, but converting KPFM voltage maps to charge
density maps is nontrivial due to long-range forces and complex system geometry.
Here we present a strategy using finite-element method (FEM) simulations to determine
the Green's function of the KPFM probe/insulator/ground system, which allows us
to quantitatively extract surface charge. Testing our approach with synthetic
data, we find that accounting for the atomic force microscope (AFM) tip, cone,
and cantilever is necessary to recover a known input and that existing methods
lead to gross miscalculation or even the incorrect sign of the underlying charge.
Applying it to experimental data, we demonstrate its capacity to extract realistic
surface charge densities and fine details from contact-charged surfaces. Our method
gives a straightforward recipe to convert qualitative KPFM voltage data into quantitative
charge data over a range of experimental conditions, enabling quantitative CE
at the nanoscale.

text: The phytohormone auxin triggers transcriptional reprogramming through a well-characterized
perception machinery in the nucleus. By contrast, mechanisms that underlie fast
effects of auxin, such as the regulation of ion fluxes, rapid phosphorylation
of proteins or auxin feedback on its transport, remain unclear1,2,3. Whether auxin-binding
protein 1 (ABP1) is an auxin receptor has been a source of debate for decades1,4.
Here we show that a fraction of Arabidopsis thaliana ABP1 is secreted and binds
auxin specifically at an acidic pH that is typical of the apoplast. ABP1 and its
plasma-membrane-localized partner, transmembrane kinase 1 (TMK1), are required
for the auxin-induced ultrafast global phospho-response and for downstream processes
that include the activation of H+-ATPase and accelerated cytoplasmic streaming.
abp1 and tmk mutants cannot establish auxin-transporting channels and show defective
auxin-induced vasculature formation and regeneration. An ABP1(M2X) variant that
lacks the capacity to bind auxin is unable to complement these defects in abp1
mutants. These data indicate that ABP1 is the auxin receptor for TMK1-based cell-surface
signalling, which mediates the global phospho-response and auxin canalization.

text: Capacity, rate performance, and cycle life of aprotic Li–O2 batteries critically
depend on reversible electrodeposition of Li2O2. Current understanding states
surface-adsorbed versus solvated LiO2 controls Li2O2 growth as surface film or
as large particles. Herein, we show that Li2O2 forms across a wide range of electrolytes,
carbons, and current densities as particles via solution-mediated LiO2 disproportionation,
bringing into question the prevalence of any surface growth under practical conditions.
We describe a unified O2 reduction mechanism, which can explain all found capacity
relations and Li2O2 morphologies with exclusive solution discharge. Determining
particle morphology and achievable capacities are species mobilities, true areal
rate, and the degree of LiO2 association in solution. Capacity is conclusively
limited by mass transport through the tortuous Li2O2 rather than electron transport
through a passivating Li2O2 film. Provided that species mobilities and surface
growth are high, high capacities are also achieved with weakly solvating electrolytes,
which were previously considered prototypical for low capacity via surface growth.

text: The mammalian neocortex is composed of diverse neuronal and glial cell classes
that broadly arrange in six distinct laminae. Cortical layers emerge during development
and defects in the developmental programs that orchestrate cortical lamination
are associated with neurodevelopmental diseases. The developmental principle of
cortical layer formation depends on concerted radial projection neuron migration,
from their birthplace to their final target position. Radial migration occurs
in defined sequential steps, regulated by a large array of signaling pathways.
However, based on genetic loss-of-function experiments, most studies have thus
far focused on the role of cell-autonomous gene function. Yet, cortical neuron
migration in situ is a complex process and migrating neurons traverse along diverse
cellular compartments and environments. The role of tissue-wide properties and
genetic state in radial neuron migration is however not clear. Here we utilized
mosaic analysis with double markers (MADM) technology to either sparsely or globally
delete gene function, followed by quantitative single-cell phenotyping. The MADM-based
gene ablation paradigms in combination with computational modeling demonstrated
that global tissue-wide effects predominate cell-autonomous gene function albeit
in a gene-specific manner. Our results thus suggest that the genetic landscape
in a tissue critically affects the overall migration phenotype of individual cortical
projection neurons. In a broader context, our findings imply that global tissue-wide
effects represent an essential component of the underlying etiology associated
with focal malformations of cortical development in particular, and neurological
diseases in general.

text: 'When crawling through the body, leukocytes often traverse tissues that are
densely packed with extracellular matrix and other cells, and this raises the
question: How do leukocytes overcome compressive mechanical loads? Here, we show
that the actin cortex of leukocytes is mechanoresponsive and that this responsiveness
requires neither force sensing via the nucleus nor adhesive interactions with
a substrate. Upon global compression of the cell body as well as local indentation
of the plasma membrane, Wiskott-Aldrich syndrome protein (WASp) assembles into
dot-like structures, providing activation platforms for Arp2/3 nucleated actin
patches. These patches locally push against the external load, which can be obstructing
collagen fibers or other cells, and thereby create space to facilitate forward
locomotion. We show in vitro and in vivo that this WASp function is rate limiting
for ameboid leukocyte migration in dense but not in loose environments and is
required for trafficking through diverse tissues such as skin and lymph nodes.'

text: Significant advances in the synthesis and processing of colloidal nanocrystals
have given scientists and engineers access to a vast library of building blocks
with precisely defined size, shape, and composition. These materials have inspired
exciting prospects to enable bottom-up fabrication of programmable materials with
properties by design. Successfully assembling and connecting the building blocks
into superstructures in which constituent nanocrystals can purposefully interact
requires robust understanding of and control over a complex interplay of dynamic
physicochemical processes. Fluid interfaces provide an advantageous experimental
workbench to both probe and control these processes. Despite the ostensible simplicity
of fabricating nanocrystal assemblies at a fluid interface, sensitivity to processing
conditions and limited reproducibility have underscored the complexity of this
process. In situ studies have provided mechanistic insights into the competing
dynamics of key subprocesses including solvent spreading and evaporation, superlattice
formation, ligand detachment kinetics, and nanocrystal attachment. Understanding
how these subprocesses influence the complex choreography of self-assembly, structure
transformation, and oriented attachment processes presents a rich research challenge.
In this context, we present a detailed methodology for self-assembly and attachment
of lead chalcogenide nanocrystals at a liquid–gas interface as a model system
for the fabrication of mono- and multilayer cubic connected superlattices. We
discuss key experimental parameters such as the characteristics of the building
blocks and processing conditions and detailed steps from colloidal nanocrystal
injection to superlattice transfer. We hope that this Methods/Protocols paper
will provide guidance for future advances in the exciting path toward bringing
the prospect of nanocrystal-based programmable materials to fruition.

text: Ever since the first publication of the standard communication protocol for
computer-assisted electrocardiography (SCP-ECG), prENV 1064, in 1993, by the European
Committee for Standardization (CEN), SCP-ECG has become a leading example in health
informatics, enabling open, secure, and well-documented digital data exchange
at a low cost, for quick and efficient cardiovascular disease detection and management.
Based on the experiences gained, since the 1970s, in computerized electrocardiology,
and on the results achieved by the pioneering, international cooperative research
on common standards for quantitative electrocardiography (CSE), SCP-ECG was designed,
from the beginning, to empower personalized medicine, thanks to serial ECG analysis.
The fundamental concept behind SCP-ECG is to convey the necessary information
for ECG re-analysis, serial comparison, and interpretation, and to structure the
ECG data and metadata in sections that are mostly optional in order to fit all
use cases. SCP-ECG is open to the storage of the ECG signal and ECG measurement
data, whatever the ECG recording modality or computation method, and can store
the over-reading trails and ECG annotations, as well as any computerized or medical
interpretation reports. Only the encoding syntax and the semantics of the ECG
descriptors and of the diagnosis codes are standardized. We present all of the
landmarks in the development and publication of SCP-ECG, from the early 1990s
to the 2009 International Organization for Standardization (ISO) SCP-ECG standards,
including the latest version published by CEN in 2020, which now encompasses rest
and stress ECGs, Holter recordings, and protocol-based trials.
acknowledgement: This research received no external funding. The authors thank the
large number of researchers, engineers, cardiologists, and clinicians from academia,
industry, and normalization organizations who contributed to the development and
testing of the SCP-ECG standards.

text: The evidence linking innate immunity mechanisms and neurodegenerative diseases
is growing, but the specific mechanisms are incompletely understood. Experimental
data suggest that microglial TLR4 mediates the uptake and clearance of α-synuclein
also termed synucleinophagy. The accumulation of misfolded α-synuclein throughout
the brain is central to Parkinson's disease (PD). The distribution and progression
of the pathology is often attributed to the propagation of α-synuclein. Here,
we apply a classical α-synuclein propagation model of prodromal PD in wild type
and TLR4 deficient mice to study the role of TLR4 in the progression of the disease.
Our data suggest that TLR4 deficiency facilitates the α-synuclein seed spreading
associated with reduced lysosomal activity of microglia. Three months after seed
inoculation, more pronounced proteinase K-resistant α-synuclein inclusion pathology
is observed in mice with TLR4 deficiency. The facilitated propagation of α-synuclein
is associated with early loss of dopamine transporter (DAT) signal in the striatum
and loss of dopaminergic neurons in substantia nigra pars compacta of TLR4 deficient
mice. These new results support TLR4 signaling as a putative target for disease
modification to slow the progression of PD and related disorders.
