  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: To navigate through diverse tissues, migrating cells must balance persistent
    self-propelled motion with adaptive behaviors to circumvent obstacles. We identify
    a curvature-sensing mechanism underlying obstacle evasion in immune-like cells.
    Specifically, we propose that actin polymerization at the advancing edge of migrating
    cells is inhibited by the curvature-sensitive BAR domain protein Snx33 in regions
    with inward plasma membrane curvature. The genetic perturbation of this machinery
    reduces the cells’ capacity to evade obstructions combined with faster and more
    persistent cell migration in obstacle-free environments. Our results show how
    cells can read out their surface topography and utilize actin and plasma membrane
    biophysics to interpret their environment, allowing them to adaptively decide
    if they should move ahead or turn away. On the basis of our findings, we propose
    that the natural diversity of BAR domain proteins may allow cells to tune their
    curvature sensing machinery to match the shape characteristics in their environment.

  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: '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.  '

  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: 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: 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: 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: '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: Visualizing cell behavior and effector function on a single cell level has
    been crucial for understanding key aspects of mammalian biology. Due to their
    small size, large number and rapid recruitment into thrombi, there is a lack of
    data on fate and behavior of individual platelets in thrombosis and hemostasis.
    Here we report the use of platelet lineage restricted multi-color reporter mouse
    strains to delineate platelet function on a single cell level. We show that genetic
    labeling allows for single platelet and megakaryocyte (MK) tracking and morphological
    analysis in vivo and in vitro, while not affecting lineage functions. Using Cre-driven
    Confetti expression, we provide insights into temporal gene expression patterns
    as well as spatial clustering of MK in the bone marrow. In the vasculature, shape
    analysis of activated platelets recruited to thrombi identifies ubiquitous filopodia
    formation with no evidence of lamellipodia formation. Single cell tracking in
    complex thrombi reveals prominent myosin-dependent motility of platelets and highlights
    thrombus formation as a highly dynamic process amenable to modification and intervention
    of the acto-myosin cytoskeleton. Platelet function assays combining flow cytrometry,
    as well as in vivo, ex vivo and in vitro imaging show unaltered platelet functions
    of multicolor reporter mice compared to wild-type controls. In conclusion, platelet
    lineage multicolor reporter mice prove useful in furthering our understanding
    of platelet and MK biology on a single cell level.

  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 mouse dendritic cells (DCs) as a 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 the pathogenic strain CFT073 to CD14 reduced DC migration
    by overactivation of integrins and blunted expression of co-stimulatory molecules
    by overactivating the NFAT (nuclear factor of activated T-cells) pathway, both
    rate-limiting factors of T cell activation. This response was binary at the single-cell
    level, but averaged in larger populations exposed to both piliated and non-piliated
    pathogens, presumably via the exchange of immunomodulatory cytokines. 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: Molecular catch bonds are ubiquitous in biology and essential for processes
    like leucocyte extravasion1 and cellular mechanosensing2. Unlike normal (slip)
    bonds, catch bonds strengthen under tension. The current paradigm is that this
    feature provides ‘strength on demand3’, thus enabling cells to increase rigidity
    under stress1,4,5,6. However, catch bonds are often weaker than slip bonds because
    they have cryptic binding sites that are usually buried7,8. Here we show that
    catch bonds render reconstituted cytoskeletal actin networks stronger than slip
    bonds, even though the individual bonds are weaker. Simulations show that slip
    bonds remain trapped in stress-free areas, whereas weak binding allows catch bonds
    to mitigate crack initiation by moving to high-tension areas. This ‘dissociation
    on demand’ explains how cells combine mechanical strength with the adaptability
    required for shape change, and is relevant to diseases where catch bonding is
    compromised7,9, including focal segmental glomerulosclerosis10 caused by the α-actinin-4
    mutant studied here. We surmise that catch bonds are the key to create life-like
    materials.

  text: Intravascular neutrophils and platelets collaborate in maintaining host integrity,
    but their interaction can also trigger thrombotic complications. We report here
    that cooperation between neutrophil and platelet lineages extends to the earliest
    stages of platelet formation by megakaryocytes in the bone marrow. Using intravital
    microscopy, we show that neutrophils “plucked” intravascular megakaryocyte extensions,
    termed proplatelets, to control platelet production. Following CXCR4-CXCL12-dependent
    migration towards perisinusoidal megakaryocytes, plucking neutrophils actively
    pulled on proplatelets and triggered myosin light chain and extracellular-signal-regulated
    kinase activation through reactive oxygen species. By these mechanisms, neutrophils
    accelerate proplatelet growth and facilitate continuous release of platelets in
    steady state. Following myocardial infarction, plucking neutrophils drove excessive
    release of young, reticulated platelets and boosted the risk of recurrent ischemia.
    Ablation of neutrophil plucking normalized thrombopoiesis and reduced recurrent
    thrombosis after myocardial infarction and thrombus burden in venous thrombosis.
    We establish neutrophil plucking as a target to reduce thromboischemic events.

  text: Social distancing is an effective way to prevent the spread of disease in
    societies, whereas infection elimination is a key element of organismal immunity.
    Here, we discuss how the study of social insects such as ants — which form a superorganism
    of unconditionally cooperative individuals and thus represent a level of organization
    that is intermediate between a classical society of individuals and an organism
    of cells — can help to determine common principles of disease defence across levels
    of organization.

  text: "Detachment of the cancer cells from the bulk of the tumor is the first step
    of metastasis, which\r\nis the primary cause of cancer related deaths. It is unclear,
    which factors contribute to this step.\r\nRecent studies indicate a crucial role
    of the tumor microenvironment in malignant\r\ntransformation and metastasis. Studying
    cancer cell invasion and detachments quantitatively in\r\nthe context of its physiological
    microenvironment is technically challenging. Especially, precise\r\ncontrol of
    microenvironmental properties in vivo is currently not possible. Here, I studied
    the\r\nrole of microenvironment geometry in the invasion and detachment of cancer
    cells from the\r\nbulk with a simplistic and reductionist approach. In this approach,
    I engineered microfluidic\r\ndevices to mimic a pseudo 3D extracellular matrix
    environment, where I was able to\r\nquantitatively tune the geometrical configuration
    of the microenvironment and follow tumor\r\ncells with fluorescence live imaging.
    To aid quantitative analysis I developed a widely applicable\r\nsoftware application
    to automatically analyze and visualize particle tracking data.\r\nQuantitative
    analysis of tumor cell invasion in isotropic and anisotropic microenvironments\r\nshowed
    that heterogeneity in the microenvironment promotes faster invasion and more\r\nfrequent
    detachment of cells. These observations correlated with overall higher speed of
    cells at\r\nthe edge of the bulk of the cells. In heterogeneous microenvironments
    cells preferentially\r\npassed through larger pores, thus invading areas of least
    resistance and generating finger-like\r\ninvasive structures. The detachments
    occurred mostly at the tips of these structures.\r\nTo investigate the potential
    mechanism, we established a two dimensional model to simulate\r\nactive Brownian
    particles representing the cell nuclei dynamics. These simulations backed our
    in\r\nvitro observations without the need of precise fitting the simulation parameters.
    Our model\r\nsuggests the importance of the pore heterogeneity in the direction
    perpendicular to the\r\norientation of bias field (lateral heterogeneity), which
    causes the interface roughening."

  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: Hematopoietic-specific protein 1 (Hem1) is an essential subunit of the WAVE
    regulatory complex (WRC) in immune cells. WRC is crucial for Arp2/3 complex activation
    and the protrusion of branched actin filament networks. Moreover, Hem1 loss of
    function in immune cells causes autoimmune diseases in humans. Here, we show that
    genetic removal of Hem1 in macrophages diminishes frequency and efficacy of phagocytosis
    as well as phagocytic cup formation in addition to defects in lamellipodial protrusion
    and migration. Moreover, Hem1-null macrophages displayed strong defects in cell
    adhesion despite unaltered podosome formation and concomitant extracellular matrix
    degradation. Specifically, dynamics of both adhesion and de-adhesion as well as
    concomitant phosphorylation of paxillin and focal adhesion kinase (FAK) were significantly
    compromised. Accordingly, disruption of WRC function in non-hematopoietic cells
    coincided with both defects in adhesion turnover and altered FAK and paxillin
    phosphorylation. Consistently, platelets exhibited reduced adhesion and diminished
    integrin αIIbβ3 activation upon WRC removal. Interestingly, adhesion phenotypes,
    but not lamellipodia formation, were partially rescued by small molecule activation
    of FAK. A full rescue of the phenotype, including lamellipodia formation, required
    not only the presence of WRCs but also their binding to and activation by Rac.
    Collectively, our results uncover that WRC impacts on integrin-dependent processes
    in a FAK-dependent manner, controlling formation and dismantling of adhesions,
    relevant for properly grabbing onto extracellular surfaces and particles during
    cell edge expansion, like in migration or phagocytosis.
