text: The differentiation of cells depends on a precise control of their internal
organization, which is the result of a complex dynamic interplay between the cytoskeleton,
molecular motors, signaling molecules, and membranes. For example, in the developing
neuron, the protein ADAP1 (ADP-ribosylation factor GTPase-activating protein [ArfGAP]
with dual pleckstrin homology [PH] domains 1) has been suggested to control dendrite
branching by regulating the small GTPase ARF6. Together with the motor protein
KIF13B, ADAP1 is also thought to mediate delivery of the second messenger phosphatidylinositol
(3,4,5)-trisphosphate (PIP3) to the axon tip, thus contributing to PIP3 polarity.
However, what defines the function of ADAP1 and how its different roles are coordinated
are still not clear. Here, we studied ADAP1’s functions using in vitro reconstitutions.
We found that KIF13B transports ADAP1 along microtubules, but that PIP3 as well
as PI(3,4)P2 act as stop signals for this transport instead of being transported.
We also demonstrate that these phosphoinositides activate ADAP1’s enzymatic activity
to catalyze GTP hydrolysis by ARF6. Together, our results support a model for
the cellular function of ADAP1, where KIF13B transports ADAP1 until it encounters
high PIP3/PI(3,4)P2 concentrations in the plasma membrane. Here, ADAP1 disassociates
from the motor to inactivate ARF6, promoting dendrite branching.

text: Dendritic cells (DCs) are crucial for the priming of naive T cells and the
initiation of adaptive immunity. Priming is initiated at a heterologous cell–cell
contact, the immunological synapse (IS). While it is established that F-actin
dynamics regulates signaling at the T cell side of the contact, little is known
about the cytoskeletal contribution on the DC side. Here, we show that the DC
actin cytoskeleton is decisive for the formation of a multifocal synaptic structure,
which correlates with T cell priming efficiency. DC actin at the IS appears in
transient foci that are dynamized by the WAVE regulatory complex (WRC). The absence
of the WRC in DCs leads to stabilized contacts with T cells, caused by an increase
in ICAM1-integrin–mediated cell–cell adhesion. This results in lower numbers of
activated and proliferating T cells, demonstrating an important role for DC actin
in the regulation of immune synapse functionality.

text: Gradients of chemokines and growth factors guide migrating cells and morphogenetic
processes. Migration of antigen-presenting dendritic cells from the interstitium
into the lymphatic system is dependent on chemokine CCL21, which is secreted by
endothelial cells of the lymphatic capillary, binds heparan sulfates and forms
gradients decaying into the interstitium. Despite the importance of CCL21 gradients,
and chemokine gradients in general, the mechanisms of gradient formation are unclear.
Studies on fibroblast growth factors have shown that limited diffusion is crucial
for gradient formation. Here, we used the mouse dermis as a model tissue to address
the necessity of CCL21 anchoring to lymphatic capillary heparan sulfates in the
formation of interstitial CCL21 gradients. Surprisingly, the absence of lymphatic
endothelial heparan sulfates resulted only in a modest decrease of CCL21 levels
at the lymphatic capillaries and did neither affect interstitial CCL21 gradient
shape nor dendritic cell migration toward lymphatic capillaries. Thus, heparan
sulfates at the level of the lymphatic endothelium are dispensable for the formation
of a functional CCL21 gradient.

text: De novo loss of function mutations in the ubiquitin ligase-encoding gene Cullin3
lead to autism spectrum disorder (ASD). In mouse, constitutive haploinsufficiency
leads to motor coordination deficits as well as ASD-relevant social and cognitive
impairments. However, induction of Cul3 haploinsufficiency later in life does
not lead to ASD-relevant behaviors, pointing to an important role of Cul3 during
a critical developmental window. Here we show that Cul3 is essential to regulate
neuronal migration and, therefore, constitutive Cul3 heterozygous mutant mice
display cortical lamination abnormalities. At the molecular level, we found that
Cul3 controls neuronal migration by tightly regulating the amount of Plastin3
(Pls3), a previously unrecognized player of neural migration. Furthermore, we
found that Pls3 cell-autonomously regulates cell migration by regulating actin
cytoskeleton organization, and its levels are inversely proportional to neural
migration speed. Finally, we provide evidence that cellular phenotypes associated
with autism-linked gene haploinsufficiency can be rescued by transcriptional activation
of the intact allele in vitro, offering a proof of concept for a potential therapeutic
approach for ASDs.

text: Bacteria-host interactions represent a continuous trade-off between benefit
and risk. Thus, the host immune response is faced with a non-trivial problem –
accommodate beneficial commensals and remove harmful pathogens. This is especially
difficult as molecular patterns, such as lipopolysaccharide or specific surface
organelles such as pili, are conserved in both, commensal and pathogenic bacteria.
Type 1 pili, tightly regulated by phase variation, are considered an important
virulence factor of pathogenic bacteria as they facilitate invasion into host
cells. While invasion represents a de facto passive mechanism for pathogens to
escape the host immune response, we demonstrate a fundamental role of type 1 pili
as active modulators of the innate and adaptive immune response.

abstract:
- lang: eng
text: A key attribute of persistent or recurring bacterial infections is the ability
of the pathogen to evade the host’s immune response. Many Enterobacteriaceae express
type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and
establish persistent infections. However, the molecular mechanisms and strategies
by which bacteria actively circumvent the immune response of the host remain poorly
understood. Here, we identified CD14, the major co-receptor for lipopolysaccharide
detection, on dendritic cells as a previously undescribed binding partner of FimH,
the protein located at the tip of the type 1 pilus of Escherichia coli. The FimH
amino acids involved in CD14 binding are highly conserved across pathogenic and
non-pathogenic strains. Binding of pathogenic bacteria to CD14 lead to reduced
dendritic cell migration and blunted expression of co-stimulatory molecules, both
rate-limiting factors of T cell activation. While defining an active molecular
mechanism of immune evasion by pathogens, the interaction between FimH and CD14
represents a potential target to interfere with persistent and recurrent infections,
such as urinary tract infections or Crohn’s disease.

text: Attachment of adhesive molecules on cell culture surfaces to restrict cell
adhesion to defined areas and shapes has been vital for the progress of in vitro
research. In currently existing patterning methods, a combination of pattern properties
such as stability, precision, specificity, high-throughput outcome, and spatiotemporal
control is highly desirable but challenging to achieve. Here, we introduce a versatile
and high-throughput covalent photoimmobilization technique, comprising a light-dose-dependent
patterning step and a subsequent functionalization of the pattern via click chemistry.
This two-step process is feasible on arbitrary surfaces and allows for generation
of sustainable patterns and gradients. The method is validated in different biological
systems by patterning adhesive ligands on cell-repellent surfaces, thereby constraining
the growth and migration of cells to the designated areas. We then implement a
sequential photopatterning approach by adding a second switchable patterning step,
allowing for spatiotemporal control over two distinct surface patterns. As a proof
of concept, we reconstruct the dynamics of the tip/stalk cell switch during angiogenesis.
Our results show that the spatiotemporal control provided by our “sequential photopatterning”
system is essential for mimicking dynamic biological processes and that our innovative
approach has great potential for further applications in cell science.

text: 'Cells navigating through complex tissues face a fundamental challenge: while
multiple protrusions explore different paths, the cell needs to avoid entanglement.
How a cell surveys and then corrects its own shape is poorly understood. Here,
we demonstrate that spatially distinct microtubule dynamics regulate amoeboid
cell migration by locally promoting the retraction of protrusions. In migrating
dendritic cells, local microtubule depolymerization within protrusions remote
from the microtubule organizing center triggers actomyosin contractility controlled
by RhoA and its exchange factor Lfc. Depletion of Lfc leads to aberrant myosin
localization, thereby causing two effects that rate-limit locomotion: (1) impaired
cell edge coordination during path finding and (2) defective adhesion resolution.
Compromised shape control is particularly hindering in geometrically complex microenvironments,
where it leads to entanglement and ultimately fragmentation of the cell body.
We thus demonstrate that microtubules can act as a proprioceptive device: they
sense cell shape and control actomyosin retraction to sustain cellular coherence.'

text: Eukaryotic cells migrate by coupling the intracellular force of the actin
cytoskeleton to the environment. While force coupling is usually mediated by transmembrane
adhesion receptors, especially those of the integrin family, amoeboid cells such
as leukocytes can migrate extremely fast despite very low adhesive forces1. Here
we show that leukocytes cannot only migrate under low adhesion but can also transmit
forces in the complete absence of transmembrane force coupling. When confined
within three-dimensional environments, they use the topographical features of
the substrate to propel themselves. Here the retrograde flow of the actin cytoskeleton
follows the texture of the substrate, creating retrograde shear forces that are
sufficient to drive the cell body forwards. Notably, adhesion-dependent and adhesion-independent
migration are not mutually exclusive, but rather are variants of the same principle
of coupling retrograde actin flow to the environment and thus can potentially
operate interchangeably and simultaneously. As adhesion-free migration is independent
of the chemical composition of the environment, it renders cells completely autonomous
in their locomotive behaviour.

text: Cell migration entails networks and bundles of actin filaments termed lamellipodia
and microspikes or filopodia, respectively, as well as focal adhesions, all of
which recruit Ena/VASP family members hitherto thought to antagonize efficient
cell motility. However, we find these proteins to act as positive regulators of
migration in different murine cell lines. CRISPR/Cas9-mediated loss of Ena/VASP
proteins reduced lamellipodial actin assembly and perturbed lamellipodial architecture,
as evidenced by changed network geometry as well as reduction of filament length
and number that was accompanied by abnormal Arp2/3 complex and heterodimeric capping
protein accumulation. Loss of Ena/VASP function also abolished the formation of
microspikes normally embedded in lamellipodia, but not of filopodia capable of
emanating without lamellipodia. Ena/VASP-deficiency also impaired integrin-mediated
adhesion accompanied by reduced traction forces exerted through these structures.
Our data thus uncover novel Ena/VASP functions of these actin polymerases that
are fully consistent with their promotion of cell migration.

text: The WAVE regulatory complex (WRC) is crucial for assembly of the peripheral
branched actin network constituting one of the main drivers of eukaryotic cell
migration. Here, we uncover an essential role of the hematopoietic-specific WRC
component HEM1 for immune cell development. Germline-encoded HEM1 deficiency underlies
an inborn error of immunity with systemic autoimmunity, at cellular level marked
by WRC destabilization, reduced filamentous actin, and failure to assemble lamellipodia.
Hem1−/− mice display systemic autoimmunity, phenocopying the human disease. In
the absence of Hem1, B cells become deprived of extracellular stimuli necessary
to maintain the strength of B cell receptor signaling at a level permissive for
survival of non-autoreactive B cells. This shifts the balance of B cell fate choices
toward autoreactive B cells and thus autoimmunity.

text: Cell production and differentiation for the acquisition of specific functions
are key features of living systems. The dynamic network of cellular microtubules
provides the necessary platform to accommodate processes associated with the transition
of cells through the individual phases of cytogenesis. Here, we show that the
plant hormone cytokinin fine‐tunes the activity of the microtubular cytoskeleton
during cell differentiation and counteracts microtubular rearrangements driven
by the hormone auxin. The endogenous upward gradient of cytokinin activity along
the longitudinal growth axis in Arabidopsis thaliana roots correlates with robust
rearrangements of the microtubule cytoskeleton in epidermal cells progressing
from the proliferative to the differentiation stage. Controlled increases in cytokinin
activity result in premature re‐organization of the microtubule network from transversal
to an oblique disposition in cells prior to their differentiation, whereas attenuated
hormone perception delays cytoskeleton conversion into a configuration typical
for differentiated cells. Intriguingly, cytokinin can interfere with microtubules
also in animal cells, such as leukocytes, suggesting that a cytokinin‐sensitive
control pathway for the microtubular cytoskeleton may be at least partially conserved
between plant and animal cells.

text: Breakdown of vascular barriers is a major complication of inflammatory diseases.
Anucleate platelets form blood-clots during thrombosis, but also play a crucial
role in inflammation. While spatio-temporal dynamics of clot formation are well
characterized, the cell-biological mechanisms of platelet recruitment to inflammatory
micro-environments remain incompletely understood. Here we identify Arp2/3-dependent
lamellipodia formation as a prominent morphological feature of immune-responsive
platelets. Platelets use lamellipodia to scan for fibrin(ogen) deposited on the
inflamed vasculature and to directionally spread, to polarize and to govern haptotactic
migration along gradients of the adhesive ligand. Platelet-specific abrogation
of Arp2/3 interferes with haptotactic repositioning of platelets to microlesions,
thus impairing vascular sealing and provoking inflammatory microbleeding. During
infection, haptotaxis promotes capture of bacteria and prevents hematogenic dissemination,
rendering platelets gate-keepers of the inflamed microvasculature. Consequently,
these findings identify haptotaxis as a key effector function of immune-responsive
platelets.

text: T lymphocytes utilize amoeboid migration to navigate effectively within complex
microenvironments. The precise rearrangement of the actin cytoskeleton required
for cellular forward propulsion is mediated by actin regulators, including the
actin‐related protein 2/3 (Arp2/3) complex, a macromolecular machine that nucleates
branched actin filaments at the leading edge. The consequences of modulating Arp2/3
activity on the biophysical properties of the actomyosin cortex and downstream
T cell function are incompletely understood. We report that even a moderate decrease
of Arp3 levels in T cells profoundly affects actin cortex integrity. Reduction
in total F‐actin content leads to reduced cortical tension and disrupted lamellipodia
formation. Instead, in Arp3‐knockdown cells, the motility mode is dominated by
blebbing migration characterized by transient, balloon‐like protrusions at the
leading edge. Although this migration mode seems to be compatible with interstitial
migration in three‐dimensional environments, diminished locomotion kinetics and
impaired cytotoxicity interfere with optimal T cell function. These findings define
the importance of finely tuned, Arp2/3‐dependent mechanophysical membrane integrity
in cytotoxic effector T lymphocyte activities.

text: A two-dimensional mathematical model for cells migrating without adhesion
capabilities is presented and analyzed. Cells are represented by their cortex,
which is modeled as an elastic curve, subject to an internal pressure force. Net
polymerization or depolymerization in the cortex is modeled via local addition
or removal of material, driving a cortical flow. The model takes the form of a
fully nonlinear degenerate parabolic system. An existence analysis is carried
out by adapting ideas from the theory of gradient flows. Numerical simulations
show that these simple rules can account for the behavior observed in experiments,
suggesting a possible mechanical mechanism for adhesion-independent motility.

text: Platelets are small anucleate cellular fragments that are released by megakaryocytes
and safeguard vascular integrity through a process termed ‘haemostasis’. However,
platelets have important roles beyond haemostasis as they contribute to the initiation
and coordination of intravascular immune responses. They continuously monitor
blood vessel integrity and tightly coordinate vascular trafficking and functions
of multiple cell types. In this way platelets act as ‘patrolling officers of the
vascular highway’ that help to establish effective immune responses to infections
and cancer. Here we discuss the distinct biological features of platelets that
allow them to shape immune responses to pathogens and tumour cells, highlighting
the parallels between these responses.
