text: Immune responses rely on the rapid and coordinated migration of leukocytes.
Whereas it is well established that single-cell migration is often guided by gradients
of chemokines and other chemoattractants, it remains poorly understood how these
gradients are generated, maintained, and modulated. By combining experimental
data with theory on leukocyte chemotaxis guided by the G protein–coupled receptor
(GPCR) CCR7, we demonstrate that in addition to its role as the sensory receptor
that steers migration, CCR7 also acts as a generator and a modulator of chemotactic
gradients. Upon exposure to the CCR7 ligand CCL19, dendritic cells (DCs) effectively
internalize the receptor and ligand as part of the canonical GPCR desensitization
response. We show that CCR7 internalization also acts as an effective sink for
the chemoattractant, dynamically shaping the spatiotemporal distribution of the
chemokine. This mechanism drives complex collective migration patterns, enabling
DCs to create or sharpen chemotactic gradients. We further show that these self-generated
gradients can sustain the long-range guidance of DCs, adapt collective migration
patterns to the size and geometry of the environment, and provide a guidance cue
for other comigrating cells. Such a dual role of CCR7 as a GPCR that both senses
and consumes its ligand can thus provide a novel mode of cellular self-organization.

text: Whether one considers swarming insects, flocking birds, or bacterial colonies,
collective motion arises from the coordination of individuals and entails the
adjustment of their respective velocities. In particular, in close confinements,
such as those encountered by dense cell populations during development or regeneration,
collective migration can only arise coordinately. Yet, how individuals unify their
velocities is often not understood. Focusing on a finite number of cells in circular
confinements, we identify waves of polymerizing actin that function as a pacemaker
governing the speed of individual cells. We show that the onset of collective
motion coincides with the synchronization of the wave nucleation frequencies across
the population. Employing a simpler and more readily accessible mechanical model
system of active spheres, we identify the synchronization of the individuals’
internal oscillators as one of the essential requirements to reach the corresponding
collective state. The mechanical ‘toy’ experiment illustrates that the global
synchronous state is achieved by nearest neighbor coupling. We suggest by analogy
that local coupling and the synchronization of actin waves are essential for the
emergent, self-organized motion of cell collectives.

text: The rapid development of machine learning (ML) techniques has opened up the
data-dense field of microbiome research for novel therapeutic, diagnostic, and
prognostic applications targeting a wide range of disorders, which could substantially
improve healthcare practices in the era of precision medicine. However, several
challenges must be addressed to exploit the benefits of ML in this field fully.
In particular, there is a need to establish “gold standard” protocols for conducting
ML analysis experiments and improve interactions between microbiome researchers
and ML experts. The Machine Learning Techniques in Human Microbiome Studies (ML4Microbiome)
COST Action CA18131 is a European network established in 2019 to promote collaboration
between discovery-oriented microbiome researchers and data-driven ML experts to
optimize and standardize ML approaches for microbiome analysis. This perspective
paper presents the key achievements of ML4Microbiome, which include identifying
predictive and discriminatory ‘omics’ features, improving repeatability and comparability,
developing automation procedures, and defining priority areas for the novel development
of ML methods targeting the microbiome. The insights gained from ML4Microbiome
will help to maximize the potential of ML in microbiome research and pave the
way for new and improved healthcare practices.

text: Germ granules, condensates of phase-separated RNA and protein, are organelles
that are essential for germline development in different organisms. The patterning
of the granules and their relevance for germ cell fate are not fully understood.
Combining three-dimensional in vivo structural and functional analyses, we study
the dynamic spatial organization of molecules within zebrafish germ granules.
We find that the localization of RNA molecules to the periphery of the granules,
where ribosomes are localized, depends on translational activity at this location.
In addition, we find that the vertebrate-specific Dead end (Dnd1) protein is essential
for nanos3 RNA localization at the condensates’ periphery. Accordingly, in the
absence of Dnd1, or when translation is inhibited, nanos3 RNA translocates into
the granule interior, away from the ribosomes, a process that is correlated with
the loss of germ cell fate. These findings highlight the relevance of sub-granule
compartmentalization for post-transcriptional control and its importance for preserving
germ cell totipotency.

text: Regulation of chromatin states involves the dynamic interplay between different
histone modifications to control gene expression. Recent advances have enabled
mapping of histone marks in single cells, but most methods are constrained to
profile only one histone mark per cell. Here, we present an integrated experimental
and computational framework, scChIX-seq (single-cell chromatin immunocleavage
and unmixing sequencing), to map several histone marks in single cells. scChIX-seq
multiplexes two histone marks together in single cells, then computationally deconvolves
the signal using training data from respective histone mark profiles. This framework
learns the cell-type-specific correlation structure between histone marks, and
therefore does not require a priori assumptions of their genomic distributions.
Using scChIX-seq, we demonstrate multimodal analysis of histone marks in single
cells across a range of mark combinations. Modeling dynamics of in vitro macrophage
differentiation enables integrated analysis of chromatin velocity. Overall, scChIX-seq
unlocks systematic interrogation of the interplay between histone modifications
in single cells.

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: 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.

abstract:
- lang: eng
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: 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: 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: 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: '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: 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.
