text: Atopic dermatitis (AD) is the most common chronic inflammatory skin disease
worldwide. AD is a highly complex disease with different subtypes. Many elements
of AD pathophysiology have been described, but if/how they interact with each
other or which mechanisms are important in which patients is still unclear. Langerhans
cells (LCs) are antigen-presenting cells (APCs) in the epidermis. Depending on
the context, they can act either pro- or anti-inflammatory. Many different studies
have investigated LCs in the context of AD and found them to be connected to all
major mechanisms of AD pathophysiology. As APCs, LCs recruit other immune cells
and shape the immune response, especially adaptive immunity via polarization of
T cells. As sentinel cells, LCs are primary sensors of the skin microbiome and
are important for the decision of immunity versus tolerance. LCs are also involved
with the integrity of the skin barrier by influencing tight junctions. Finally,
LCs are important cells in the neuro-immune crosstalk in the skin. In this review,
we provide an overview about the many different roles of LCs in AD. Understanding
LCs might bring us closer to a more complete understanding of this highly complex
disease. Potentially, modulating LCs might offer new options for targeted therapies
for AD patients.

text: Efficient immune responses rely on the capacity of leukocytes to traverse
diverse and complex tissues. To meet such changing environmental conditions, leukocytes
usually adopt an ameboid configuration, using their forward-positioned nucleus
as a probe to identify and follow the path of least resistance among pre-existing
pores. We show that, in dense environments where even the largest pores preclude
free passage, leukocytes position their nucleus behind the centrosome and organelles.
The local compression imposed on the cell body by its surroundings triggers assembly
of a central F-actin pool, located between cell front and nucleus. Central actin
pushes outward to transiently dilate a path for organelles and nucleus. Pools
of central and front actin are tightly coupled and experimental depletion of the
central pool enhances actin accumulation and protrusion formation at the cell
front. Although this shifted balance speeds up cells in permissive environments,
migration in restrictive environments is impaired, as the unleashed leading edge
dissociates from the trapped cell body. Our findings establish an actin regulatory
loop that balances path dilation with advancement of the leading edge to maintain
cellular coherence.

text: "Immune responses depend on the coordinated and efficient migration of leukocytes.
These\r\ncells, which are embedded and tightly confined within tissues, must navigate
and traverse\r\ndiverse and complex three-dimensional environments. Leukocytes
adapt their locomotory\r\nbehavior to the mechanical, geometrical, and biochemical
characteristics of their\r\nsurroundings. In low-density environments, where the
pore size of the interstitial matrix\r\nallows free passage, these cells position
the nucleus directly behind the lamellipodium, the\r\nprotrusive actin structure
that forms the leading front of the cell. In this configuration, they\r\nuse the
nucleus as a gauge to identify the path of least resistance.\r\nHere, we show
that in high-density environments, where the pore size precludes free passage\r\nof
the cell body, leukocytes reposition the microtubule-organizing center (MTOC)
and\r\nassociated organelles in front of the nucleus. In this configuration, they
use actin structures\r\nprotruding orthogonally to the direction of migration
in order to open a path for the cell body.\r\nWe identify two distinct actin populations
that serve this purpose at different subcellular\r\nlocalizations. At the leading
edge, local indentation of the plasma membrane leads to\r\nrecruitment of the
Wiskott-Aldrich syndrome protein (WASp), which, via Arp2/3, results in\r\nthe
formation of individual actin foci. At the cell body, actin polymerization is
triggered by\r\nDOCK8, a Cdc42 exchange factor, resulting in the formation of
a central actin pool.\r\nWe demonstrate that the central and peripheral actin
pools are functionally communicating\r\nand that depletion of the central actin
pool leads to increased actin accumulation at the cell\r\nfront, resulting in
excessive extension of the leading edge."

text: Cell and tissue movement in development, cancer invasion, and immune response
relies on chemical or mechanical guidance cues. In many systems, this behavior
is locally directed by self-generated signaling gradients rather than long-range,
prepatterned cues. However, how heterogeneous mixtures of cells interact nonreciprocally
and navigate through self-generated gradients remains largely unexplored. Here,
we introduce a theoretical framework for the self-organized chemotaxis of heterogeneous
cell populations. We find that the relative chemotactic sensitivities of different
cell populations control their long-time coupling and comigration dynamics, with
boundary conditions such as external cell and attractant reservoirs substantially
influencing the migration patterns. Our model predicts an optimal parameter regime
that enables robust and colocalized migration. We test our theoretical predictions
with in vitro experiments demonstrating the comigration of distinct immune cell
populations, and quantitatively reproduce observed migration patterns under wild-type
and perturbed conditions. Interestingly, immune cell comigration occurs close
to the predicted optimal regime. Finally, we incorporate mechanical interactions
into our framework, revealing a nontrivial interplay between chemotactic and mechanical
nonreciprocity in driving collective migration. Together, our findings suggest
that self-generated chemotaxis is a robust strategy for the navigation of mixed
cell populations.

text: While tumor malignancy has been extensively studied under the prism of genetic
and epigenetic heterogeneity, tumor cell states also critically depend on reciprocal
interactions with the microenvironment. This raises the hitherto untested possibility
that heterogeneity of the untransformed tumor stroma can actively fuel malignant
progression. As biological heterogeneity is inherently difficult to control, we
adopted a reductionist approach and let tumor cells invade micro-engineered environments
harboring obstacles with precision-controlled geometry. We find that not only
the presence of obstacles, but more surprisingly their spatial disorder, causes
a drastic shift from a collective to a single-cell mode of invasion – comparable
in strength to cadherin loss. Combining live-imaging and perturbation experiments
with minimal biophysical modeling, we demonstrate that cell detachments result
both from local geometrical constraints and a global integration of spatial disorder
over time. We show that different types of microenvironments map onto different
universality classes of invasion dynamics - homogeneous substrates follow Kardar–Parisi–Zhang
(KPZ) scaling, while disordered ones exhibit exponents consistent with KPZ with
quenched disorder (KPZq). Our findings highlight generic physical principles for
how the mode of cancer cell invasion depends on environmental heterogeneity, with
potential implications to understand tumor evolution in vivo.

text: "Cell migration is a crucial process in animal development and maintenance.
It is incredibly\r\nheterogeneous, with different cell types utilizing fundamentally
distinct migration strategies.\r\nThe strategies also depend on the cellular microenvironment,
where cells can switch between\r\nmigration modes as they encounter new environmental
cues. In this thesis, we investigated\r\nhow dendritic cells adapt their migration
strategy when encountering geometrically,\r\nmechanically and chemically distinct
environments.\r\nWhen dendritic cells are embedded in a homogeneous fibrous network,
they migrate in a fast\r\nand directional amoeboid manner. In this migration strategy,
extracellular proteolysis and\r\nintegrin-mediated adhesions are dispensable.
Instead, the cells use topography of the\r\nenvironment to propel their cell body
forward. To migrate efficiently in the maze of different\r\npore sizes, they position
the nucleus ahead of the microtubule organizing center (MTOC) and\r\nuse it to
gauge the pores to identify the path of least resistance. Our aim was to identify\r\nwhether
dendritic cells adapt their migration strategy when encountering asymmetrical\r\ntransitions
into much denser environments with limited choice of large pores. In such invasive\r\ntransitions
it is unclear if the cells can cross tight pores without the use of adhesions
and\r\nextracellular proteolysis and whether they maintain the nucleus in the
cell front.\r\nUsing various cell migration assays such as fibrous 3D collagen
gels, geometrically defined\r\nmicrochannels with constrictions and simplistic
under agarose migration assay, we provide\r\na comprehensive characterization
of invasive migration of dendritic cells. We show that\r\nduring invasion the
cells stall and stretch, reflecting the difficulty to translocate the bulky cell\r\nbody
into the dense environment. In collagen gels, we show that dendritic cells can
invade\r\nwithout proteolysis and adhesions. Instead, they utilize contractility,
which can lead to largescale collagen compressions. During invasion, the nucleus
stalls at tight constrictions, leading\r\nto a transient organelle reorientation.
To resolve the stalling, upregulated rear contractility is\r\nrequired. This contractile
force is simultaneously necessary for reverting the nucleus back to\r\nthe cell
front after invasion and maintaining this positioning during permissive migration.\r\nA
functional role of the reorientation was uncovered in the first collaboration
project.\r\nA prominent central actin pool was identified around the MTOC, especially
pronounced in\r\ndense and compressive environments. The actin pool was shown
to generate pushing forces\r\nto dilate the space for cell translocation. These
forces are only necessary in non-permissive\r\nenvironments, where the nucleus
reorients to the cell rear, allowing the actin pool to\r\ngenerate space. In permissive
environments where space generation is dispensable, the\r\nMTOC is located behind
the nucleus and the actin cloud has reduced intensity, allowing more\r\nactin
to be incorporated into the lamellipodium, speeding up migration.\r\nIn the second
collaboration project, we investigated the effects of distinct chemical\r\nenvironments
on dendritic cell migration. The strikingly persistent migration of these cells\r\nwas
explained by their ability to modulate and even self-generate chemokine gradients.
This\r\nallows the cells to migrate faster and more persistent in uniform chemokine
fields compared\r\nto imposed chemokine gradients. The chemokine receptor CCR7
was identified as a crucial\r\nplayer in this process, both sensing the signal
and internalizing the chemokine to create a sink."

text: Venous thromboembolism (VTE) is a common, deadly disease with an increasing
incidence despite preventive efforts. Clinical observations have associated elevated
antibody concentrations or antibody-based therapies with thrombotic events. However,
how antibodies contribute to thrombosis is unknown. Here, we show that reduced
blood flow enabled immunoglobulin M (IgM) to bind to FcμR and the polymeric immunoglobulin
receptor (pIgR), initiating endothelial activation and platelet recruitment. Subsequently,
the procoagulant surface of activated platelets accommodated antigen- and FcγR-independent
IgG deposition. This leads to classical complement activation, setting in motion
a prothrombotic vicious circle. Key elements of this mechanism were present in
humans in the setting of venous stasis as well as in the dysregulated immunothrombosis
of COVID-19. This antibody-driven thrombosis can be prevented by pharmacologically
targeting complement. Hence, our results uncover antibodies as previously unrecognized
central regulators of thrombosis. These findings carry relevance for therapeutic
application of antibodies and open innovative avenues to target thrombosis without
compromising hemostasis.

text: Contraction and flow of the actin cell cortex have emerged as a common principle
by which cells reorganize their cytoplasm and take shape. However, how these cortical
flows interact with adjacent cytoplasmic components, changing their form and localization,
and how this affects cytoplasmic organization and cell shape remains unclear.
Here we show that in ascidian oocytes, the cooperative activities of cortical
actomyosin flows and deformation of the adjacent mitochondria-rich myoplasm drive
oocyte cytoplasmic reorganization and shape changes following fertilization. We
show that vegetal-directed cortical actomyosin flows, established upon oocyte
fertilization, lead to both the accumulation of cortical actin at the vegetal
pole of the zygote and compression and local buckling of the adjacent elastic
solid-like myoplasm layer due to friction forces generated at their interface.
Once cortical flows have ceased, the multiple myoplasm buckles resolve into one
larger buckle, which again drives the formation of the contraction pole—a protuberance
of the zygote’s vegetal pole where maternal mRNAs accumulate. Thus, our findings
reveal a mechanism where cortical actomyosin network flows determine cytoplasmic
reorganization and cell shape by deforming adjacent cytoplasmic components through
friction forces.

text: Centrioles are part of centrosomes and cilia, which are microtubule organising
centres (MTOC) with diverse functions. Despite their stability, centrioles can
disappear during differentiation, such as in oocytes, but little is known about
the regulation of their structural integrity. Our previous research revealed that
the pericentriolar material (PCM) that surrounds centrioles and its recruiter,
Polo kinase, are downregulated in oogenesis and sufficient for maintaining both
centrosome structural integrity and MTOC activity. We now show that the expression
of specific components of the centriole cartwheel and wall, including ANA1/CEP295,
is essential for maintaining centrosome integrity. We find that Polo kinase requires
ANA1 to promote centriole stability in cultured cells and eggs. In addition, ANA1
expression prevents the loss of centrioles observed upon PCM-downregulation. However,
the centrioles maintained by overexpressing and tethering ANA1 are inactive, unlike
the MTOCs observed upon tethering Polo kinase. These findings demonstrate that
several centriole components are needed to maintain centrosome structure. Our
study also highlights that centrioles are more dynamic than previously believed,
with their structural stability relying on the continuous expression of multiple
components.

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: "Background: IgE-mediated degranulation of mast cells (MCs) provides rapid
protection against environmental hazards, including animal venoms. A fraction
of tissue-resident MCs intimately associates with blood vessels. These perivascular
MCs were reported to extend projections into the vessel lumen and to be the first
MCs to acquire intravenously injected IgE, suggesting that IgE loading of MCs
depends on their vascular association.\r\nObjective: We sought to elucidate the
molecular basis of the MC–blood vessel interaction and to determine its relevance
for IgE-mediated immune responses.\r\nMethods: We selectively inactivated the
Itgb1 gene, encoding the β1 chain of integrin adhesion molecules (ITGB1), in MCs
by conditional gene targeting in mice. We analyzed skin MCs for blood vessel association,
surface IgE density, and capability to bind circulating antibody specific for
MC surface molecules, as well as in vivo responses to antigen administered via
different routes.\r\nResults: Lack of ITGB1 expression severely compromised MC–blood
vessel association. ITGB1-deficient MCs showed normal densities of surface IgE
but reduced binding of intravenously injected antibodies. While their capacity
to degranulate in response to IgE ligation in vivo was unimpaired, anaphylactic
responses to antigen circulating in the vasculature were largely abolished.\r\nConclusions:
ITGB1-mediated association of MCs with blood vessels is key for MC immune surveillance
of blood vessel content, but is dispensable for slow steady-state loading of endogenous
IgE onto tissue-resident MCs."

text: CRISPR-Cas9 technology has become an essential tool for plant genome editing.
Recent advancements have significantly improved the ability to target multiple
genes simultaneously within the same genetic background through various strategies.
Additionally, there has been significant progress in developing methods for inducible
or tissue-specific editing. These advancements offer numerous possibilities for
tailored genome modifications. Building upon existing research, we have developed
an optimized and modular strategy allowing the targeting of several genes simultaneously
in combination with the synchronized expression of the Cas9 endonuclease in the
egg cell. This system allows significant editing efficiency while avoiding mosaicism.
In addition, the versatile system we propose allows adaptation to inducible and/or
tissue-specific edition according to the promoter chosen to drive the expression
of the Cas9 gene. Here, we describe a step-by-step protocol for generating the
binary vector necessary for establishing Arabidopsis edited lines using a versatile
cloning strategy that combines Gateway® and Golden Gate technologies. We describe
a versatile system that allows the cloning of as many guides as needed to target
DNA, which can be multiplexed into a polycistronic gene and combined in the same
construct with sequences for the expression of the Cas9 endonuclease. The expression
of Cas9 is controlled by selecting from among a collection of promoters, including
constitutive, inducible, ubiquitous, or tissue-specific promoters. Only one vector
containing the polycistronic gene (tRNA-sgRNA) needs to be constructed. For that,
sgRNA (composed of protospacers chosen to target the gene of interest and sgRNA
scaffold) is cloned in tandem with the pre-tRNA sequence. Then, a single recombination
reaction is required to assemble the promoter, the zCas9 coding sequence, and
the tRNA-gRNA polycistronic gene. Each element is cloned in an entry vector and
finally assembled according to the Multisite Gateway® Technology. Here, we detail
the process to express zCas9 under the control of egg cell promoter fused to enhancer
sequence (EC1.2en-EC1.1p) and to simultaneously target two multiple C2 domains
and transmembrane region protein genes (MCTP3 and MCTP4, respectively at3g57880
and at1g51570), using one or two sgRNA per gene.

text: Platelet homeostasis is essential for vascular integrity and immune defence1,2.
Although the process of platelet formation by fragmenting megakaryocytes (MKs;
thrombopoiesis) has been extensively studied, the cellular and molecular mechanisms
required to constantly replenish the pool of MKs by their progenitor cells (megakaryopoiesis)
remains unclear3,4. Here we use intravital imaging to track the cellular dynamics
of megakaryopoiesis over days. We identify plasmacytoid dendritic cells (pDCs)
as homeostatic sensors that monitor the bone marrow for apoptotic MKs and deliver
IFNα to the MK niche triggering local on-demand proliferation and maturation of
MK progenitors. This pDC-dependent feedback loop is crucial for MK and platelet
homeostasis at steady state and under stress. pDCs are best known for their ability
to function as vigilant detectors of viral infection5. We show that virus-induced
activation of pDCs interferes with their function as homeostatic sensors of megakaryopoiesis.
Consequently, activation of pDCs by SARS-CoV-2 leads to excessive megakaryopoiesis.
Together, we identify a pDC-dependent homeostatic circuit that involves innate
immune sensing and demand-adapted release of inflammatory mediators to maintain
homeostasis of the megakaryocytic lineage.

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 intricate regulatory processes behind actin polymerization play a crucial
role in cellular biology, including essential mechanisms such as cell migration
or cell division. However, the self-organizing principles governing actin polymerization
are still poorly understood. In this perspective article, we compare the Belousov-Zhabotinsky
(BZ) reaction, a classic and well understood chemical oscillator known for its
self-organizing spatiotemporal dynamics, with the excitable dynamics of polymerizing
actin. While the BZ reaction originates from the domain of inorganic chemistry,
it shares remarkable similarities with actin polymerization, including the characteristic
propagating waves, which are influenced by geometry and external fields, and the
emergent collective behavior. Starting with a general description of emerging
patterns, we elaborate on single droplets or cell-level dynamics, the influence
of geometric confinements and conclude with collective interactions. Comparing
these two systems sheds light on the universal nature of self-organization principles
in both living and inanimate systems.

text: Imaging of the immunological synapse (IS) between dendritic cells (DCs) and
T cells in suspension is hampered by suboptimal alignment of cell-cell contacts
along the vertical imaging plane. This requires optical sectioning that often
results in unsatisfactory resolution in time and space. Here, we present a workflow
where DCs and T cells are confined between a layer of glass and polydimethylsiloxane
(PDMS) that orients the cells along one, horizontal imaging plane, allowing for
fast en-face-imaging of the DC-T cell IS.

text: Regulating protein states is considered the core function of chaperones. However,
despite their importance to all major cellular processes, the conformational changes
that chaperones impart on polypeptide chains are difficult to study directly due
to their heterogeneous, dynamic, and multi-step nature. Here, we review recent
advances towards this aim using single-molecule manipulation methods, which are
rapidly revealing new mechanisms of conformational control and helping to define
a different perspective on the chaperone function.

text: 'Most motions of many-body systems at any scale in nature with sufficient
degrees of freedom tend to be chaotic; reaching from the orbital motion of planets,
the air currents in our atmosphere, down to the water flowing through our pipelines
or the movement of a population of bacteria. To the observer it is therefore intriguing
when a moving collective exhibits order. Collective motion of flocks of birds,
schools of fish or swarms of self-propelled particles or robots have been studied
extensively over the past decades but the mechanisms involved in the transition
from chaos to order remain unclear. Here, the interactions, that in most systems
give rise to chaos, sustain order. In this thesis we investigate mechanisms that
preserve, destabilize or lead to the ordered state. We show that endothelial cells
migrating in circular confinements transition to a collective rotating state and
concomitantly synchronize the frequencies of nucleating actin waves within individual
cells. Consequently, the frequency dependent cell migration speed uniformizes
across the population. Complementary to the WAVE dependent nucleation of traveling
actin waves, we show that in leukocytes the actin polymerization depending on
WASp generates pushing forces locally at stationary patches. Next, in pipe flows,
we study methods to disrupt the self--sustaining cycle of turbulence and therefore
relaminarize the flow. While we find in pulsating flow conditions that turbulence
emerges through a helical instability during the decelerating phase. Finally,
we show quantitatively in brain slices of mice that wild-type control neurons
can compensate the migratory deficits of a genetically modified neuronal sub--population
in the developing cortex. '
