  text: During metazoan development, immune surveillance and cancer dissemination,
    cells migrate in complex three-dimensional microenvironments1,2,3. These spaces
    are crowded by cells and extracellular matrix, generating mazes with differently
    sized gaps that are typically smaller than the diameter of the migrating cell4,5.
    Most mesenchymal and epithelial cells and some—but not all—cancer cells actively
    generate their migratory path using pericellular tissue proteolysis6. By contrast,
    amoeboid cells such as leukocytes use non-destructive strategies of locomotion7,
    raising the question how these extremely fast cells navigate through dense tissues.
    Here we reveal that leukocytes sample their immediate vicinity for large pore
    sizes, and are thereby able to choose the path of least resistance. This allows
    them to circumnavigate local obstacles while effectively following global directional
    cues such as chemotactic gradients. Pore-size discrimination is facilitated by
    frontward positioning of the nucleus, which enables the cells to use their bulkiest
    compartment as a mechanical gauge. Once the nucleus and the closely associated
    microtubule organizing centre pass the largest pore, cytoplasmic protrusions still
    lingering in smaller pores are retracted. These retractions are coordinated by
    dynamic microtubules; when microtubules are disrupted, migrating cells lose coherence
    and frequently fragment into migratory cytoplasmic pieces. As nuclear positioning
    in front of the microtubule organizing centre is a typical feature of amoeboid
    migration, our findings link the fundamental organization of cellular polarity
    to the strategy of locomotion.

  text: Lymph nodes  are es s ential organs  of the immune  s ys tem where adaptive
    immune responses originate, and consist of various leukocyte populations and a
    stromal backbone. Fibroblastic reticular  cells (FRCs) are  the  main  stromal  cells
    and  form  a sponge-like extracellular matrix network,   called  conduits ,  which  they   thems
    elves   enwrap   and  contract.  Lymph,  containing  s oluble  antigens ,  arrive
    in  lymph  nodes  via afferent lymphatic  vessels that  connect  to  the  s ubcaps
    ular  s inus   and  conduit  network.  According  to  the  current  paradigm,  the  conduit  network   dis
    tributes   afferent  lymph  through   lymph  nodes   and  thus   provides   acces
    s   for  immune  cells to lymph-borne  antigens. An  elas tic  caps ule  s urrounds   the  organ  and  confines   the
    immune  cells and  FRC  network.   Lymph   nodes   are  completely  packed  with  lymphocytes   and  lymphocyte  numbers  directly  dictates  the
    size  of  the  organ.  Although  lymphocytes   cons tantly  enter  and  leave  the  lymph  node,  its   s
    ize  remains   remarkedly   s table  under  homeostatic conditions. It is only
    partly known  how the cellularity and s ize of the lymph node is regulated and  how  the  lymph  node  is
    able to swell in inflammation.  The role of the FRC network   in  lymph  node   s
    welling  and  trans fer  of  fluids   are  inves tigated in  this   thes is.  Furthermore,   we  s
    tudied  what  trafficking  routes   are  us ed  by  cancer  cells   in  lymph  nodes   to  form  distal
    metastases.We examined the role of a mechanical feedback in regulation of lymph  node
    swelling. Using parallel plate compression  and UV-las er  cutting  experiments   we  dis
    s ected  the  mechanical  force dynamics  of the whole lymph  node, and individually
    for FRCs  and the  caps ule. Physical forces   generated  by  packed  lymphocytes   directly  affect  the  tens
    ion  on  the  FRC  network  and  capsule,  which  increases  its  resistance  to   swelling.  This  implies  a  feedback  mechanism  between   tis
    s ue   pres s ure   and   ability   of   lymphocytes    to   enter   the   organ.   Following   inflammation,  the  lymph  node  swells
    ∼10 fold in two weeks . Yet, what  is  the role  for tens ion on  the  FRC  network   and  caps
    ule,  and  how  are  lymphocytes   able  to  enter  in  conditions  that resist
    swelling remain open ques tions . We s how that tens ion on the FRC network is  important
    to  limit  the  swelling  rate  of  the  organ  so  that  the  FRC  network  can  grow  in  a  coordinated  fashion.
    This is illustrated by interfering with FRC contractility, which leads to faster
    swelling rates  and a dis organized FRC network  in the inflamed lymph  node.
    Growth  of the FRC network  in  turn  is   expected  to  releas e  tens ion  on  thes
    e  s tructures   and  lowers   the  res is tance  to  swelling, thereby allowing
    more lymphocytes to enter the organ and drive more swelling. Halt of  swelling
    coincides   with  a  thickening  of  the  caps ule,  which  forms   a  thick  res
    is tant  band  around  the organ and lowers  tens ion on the FRC network  to form
    a new force equilibrium.The  FRC  and  conduit   network   are  further   believed  to  be  a  privileged  s
    ite  of  s oluble  information  within  the  lymph  node,  although  many  details   remain  uns
    olved.  We  s how  by  3D  ultra-recons truction   that  FRCs   and  antigen  pres
    enting  cells   cover  the  s urface  of  conduit  s ys tem for more  than 99%
    and we dis cus s  the implications  for s oluble information  exchangeat the conduit
    level.Finally, there  is an ongoing debate in the cancer field whether and how
    cancer cells  in lymph nodes   s eed  dis tal  metas tas es .  We  s how  that  cancer  cells   infus
    ed  into  the  lymph  node  can  utilize trafficking routes of immune  cells and  rapidly  migrate  to  blood  vessels.
    Once  in  the  blood circulation,  these cells are able to form  metastases in
    distal tissues.

  text: Lymphatic endothelial cells (LECs) release extracellular chemokines to guide
    the migration of dendritic cells. In this study, we report that LECs also release
    basolateral exosome-rich endothelial vesicles (EEVs) that are secreted in greater
    numbers in the presence of inflammatory cytokines and accumulate in the perivascular
    stroma of small lymphatic vessels in human chronic inflammatory diseases. Proteomic
    analyses of EEV fractions identified &gt; 1,700 cargo proteins and revealed a
    dominant motility-promoting protein signature. In vitro and ex vivo EEV fractions
    augmented cellular protrusion formation in a CX3CL1/fractalkine-dependent fashion
    and enhanced the directional migratory response of human dendritic cells along
    guidance cues. We conclude that perilymphatic LEC exosomes enhance exploratory
    behavior and thus promote directional migration of CX3CR1-expressing cells in
    complex tissue environments.

  text: Directed migration of cells relies on their ability to sense directional guidance
    cues and to interact with pericellular structures in order to transduce contractile
    cytoskeletal- into mechanical forces. These biomechanical processes depend highly
    on microenvironmental factors such as exposure to 2D surfaces or 3D matrices.
    In vivo, the majority of cells are exposed to 3D environments. Data on 3D cell
    migration are mostly derived from intravital microscopy or collagen-based in vitro
    assays. Both approaches offer only limited controlla-bility of experimental conditions.
    Here, we developed an automated microfluidic system that allows positioning of
    cells in 3D microenvironments containing highly controlled diffusion-based chemokine
    gradients. Tracking migration in such gradients was feasible in real time at the
    single cell level. Moreover, the setup allowed on-chip immunocytochemistry and
    thus linking of functional with phenotypical properties in individual cells. Spatially
    defined retrieval of cells from the device allows down-stream off-chip analysis.
    Using dendritic cells as a model, our setup specifically allowed us for the first
    time to quantitate key migration characteristics of cells exposed to identical
    gradients of the chemokine CCL19 yet placed on 2D vs in 3D environments. Migration
    properties between 2D and 3D migration were distinct. Morphological features of
    cells migrating in an in vitro 3D environment were similar to those of cells migrating
    in animal tissues, but different from cells migrating on a surface. Our system
    thus offers a highly controllable in vitro-mimic of a 3D environment that cells
    traffic in vivo.

  text: Migrating cells penetrate tissue barriers during development, inflammatory
    responses, and tumor metastasis. We study if migration in vivo in such three-dimensionally
    confined environments requires changes in the mechanical properties of the surrounding
    cells using embryonic Drosophila melanogaster hemocytes, also called macrophages,
    as a model. We find that macrophage invasion into the germband through transient
    separation of the apposing ectoderm and mesoderm requires cell deformations and
    reductions in apical tension in the ectoderm. Interestingly, the genetic pathway
    governing these mechanical shifts acts downstream of the only known tumor necrosis
    factor superfamily member in Drosophila, Eiger, and its receptor, Grindelwald.
    Eiger-Grindelwald signaling reduces levels of active Myosin in the germband ectodermal
    cortex through the localization of a Crumbs complex component, Patj (Pals-1-associated
    tight junction protein). We therefore elucidate a distinct molecular pathway that
    controls tissue tension and demonstrate the importance of such regulation for
    invasive migration in vivo.

  text: Cells migrating in multicellular organisms steadily traverse complex three-dimensional
    (3D) environments. To decipher the underlying cell biology, current experimental
    setups either use simplified 2D, tissue-mimetic 3D (e.g., collagen matrices) or
    in vivo environments. While only in vivo experiments are truly physiological,
    they do not allow for precise manipulation of environmental parameters. 2D in
    vitro experiments do allow mechanical and chemical manipulations, but increasing
    evidence demonstrates substantial differences of migratory mechanisms in 2D and
    3D. Here, we describe simple, robust, and versatile “pillar forests” to investigate
    cell migration in complex but fully controllable 3D environments. Pillar forests
    are polydimethylsiloxane-based setups, in which two closely adjacent surfaces
    are interconnected by arrays of micrometer-sized pillars. Changing the pillar
    shape, size, height and the inter-pillar distance precisely manipulates microenvironmental
    parameters (e.g., pore sizes, micro-geometry, micro-topology), while being easily
    combined with chemotactic cues, surface coatings, diverse cell types and advanced
    imaging techniques. Thus, pillar forests combine the advantages of 2D cell migration
    assays with the precise definition of 3D environmental parameters.

  text: Spatial patterns are ubiquitous on the subcellular, cellular and tissue level,
    and can be studied using imaging techniques such as light and fluorescence microscopy.
    Imaging data provide quantitative information about biological systems; however,
    mechanisms causing spatial patterning often remain elusive. In recent years, spatio-temporal
    mathematical modelling has helped to overcome this problem. Yet, outliers and
    structured noise limit modelling of whole imaging data, and models often consider
    spatial summary statistics. Here, we introduce an integrated data-driven modelling
    approach that can cope with measurement artefacts and whole imaging data. Our
    approach combines mechanistic models of the biological processes with robust statistical
    models of the measurement process. The parameters of the integrated model are
    calibrated using a maximum-likelihood approach. We used this integrated modelling
    approach to study in vivo gradients of the chemokine (C-C motif) ligand 21 (CCL21).
    CCL21 gradients guide dendritic cells and are important in the adaptive immune
    response. Using artificial data, we verified that the integrated modelling approach
    provides reliable parameter estimates in the presence of measurement noise and
    that bias and variance of these estimates are reduced compared to conventional
    approaches. The application to experimental data allowed the parametrization and
    subsequent refinement of the model using additional mechanisms. Among other results,
    model-based hypothesis testing predicted lymphatic vessel-dependent concentration
    of heparan sulfate, the binding partner of CCL21. The selected model provided
    an accurate description of the experimental data and was partially validated using
    published data. Our findings demonstrate that integrated statistical modelling
    of whole imaging data is computationally feasible and can provide novel biological
    insights.

  text: G-protein-coupled receptors (GPCRs) form the largest receptor family, relay
    environmental stimuli to changes in cell behavior and represent prime drug targets.
    Many GPCRs are classified as orphan receptors because of the limited knowledge
    on their ligands and coupling to cellular signaling machineries. Here, we engineer
    a library of 63 chimeric receptors that contain the signaling domains of human
    orphan and understudied GPCRs functionally linked to the light-sensing domain
    of rhodopsin. Upon stimulation with visible light, we identify activation of canonical
    cell signaling pathways, including cAMP-, Ca2+-, MAPK/ERK-, and Rho-dependent
    pathways, downstream of the engineered receptors. For the human pseudogene GPR33,
    we resurrect a signaling function that supports its hypothesized role as a pathogen
    entry site. These results demonstrate that substituting unknown chemical activators
    with a light switch can reveal information about protein function and provide
    an optically controlled protein library for exploring the physiology and therapeutic
    potential of understudied GPCRs.

  text: Lamellipodia are flat membrane protrusions formed during mesenchymal motion.
    Polymerization at the leading edge assembles the actin filament network and generates
    protrusion force. How this force is supported by the network and how the assembly
    rate is shared between protrusion and network retrograde flow determines the protrusion
    rate. We use mathematical modeling to understand experiments changing the F-actin
    density in lamellipodia of B16-F1 melanoma cells by modulation of Arp2/3 complex
    activity or knockout of the formins FMNL2 and FMNL3. Cells respond to a reduction
    of density with a decrease of protrusion velocity, an increase in the ratio of
    force to filament number, but constant network assembly rate. The relation between
    protrusion force and tension gradient in the F-actin network and the density dependency
    of friction, elasticity, and viscosity of the network explain the experimental
    observations. The formins act as filament nucleators and elongators with differential
    rates. Modulation of their activity suggests an effect on network assembly rate.
    Contrary to these expectations, the effect of changes in elongator composition
    is much weaker than the consequences of the density change. We conclude that the
    force acting on the leading edge membrane is the force required to drive F-actin
    network retrograde flow.

  text: Blood platelets are critical for hemostasis and thrombosis, but also play
    diverse roles during immune responses. We have recently reported that platelets
    migrate at sites of infection in vitro and in vivo. Importantly, platelets use
    their ability to migrate to collect and bundle fibrin (ogen)-bound bacteria accomplishing
    efficient intravascular bacterial trapping. Here, we describe a method that allows
    analyzing platelet migration in vitro, focusing on their ability to collect bacteria
    and trap bacteria under flow.

  text: T cells are actively scanning pMHC-presenting cells in lymphoid organs and
    nonlymphoid tissues (NLTs) with divergent topologies and confinement. How the
    T cell actomyosin cytoskeleton facilitates this task in distinct environments
    is incompletely understood. Here, we show that lack of Myosin IXb (Myo9b), a negative
    regulator of the small GTPase Rho, led to increased Rho-GTP levels and cell surface
    stiffness in primary T cells. Nonetheless, intravital imaging revealed robust
    motility of Myo9b−/− CD8+ T cells in lymphoid tissue and similar expansion and
    differentiation during immune responses. In contrast, accumulation of Myo9b−/−
    CD8+ T cells in NLTs was strongly impaired. Specifically, Myo9b was required for
    T cell crossing of basement membranes, such as those which are present between
    dermis and epidermis. As consequence, Myo9b−/− CD8+ T cells showed impaired control
    of skin infections. In sum, we show that Myo9b is critical for the CD8+ T cell
    adaptation from lymphoid to NLT surveillance and the establishment of protective
    tissue–resident T cell populations.

  text: Dendritic cells (DCs) are sentinels of the adaptive immune system that reside
    in peripheral organs of mammals. Upon pathogen encounter, they undergo maturation
    and up-regulate the chemokine receptor CCR7 that guides them along gradients of
    its chemokine ligands CCL19 and 21 to the next draining lymph node. There, DCs
    present peripherally acquired antigen to naïve T cells, thereby triggering adaptive
    immunity.

  text: The release of IgM is the first line of an antibody response and precedes
    the generation of high affinity IgG in germinal centers. Once secreted by freshly
    activated plasmablasts, IgM is released into the efferent lymph of reactive lymph
    nodes as early as 3 d after immunization. As pentameric IgM has an enormous size
    of 1,000 kD, its diffusibility is low, and one might wonder how it can pass through
    the densely lymphocyte-packed environment of a lymph node parenchyma in order
    to reach its exit. In this issue of JEM, Thierry et al. show that, in order to
    reach the blood stream, IgM molecules take a specific micro-anatomical route via
    lymph node conduits.

  text: 'In the here presented thesis, we explore the role of branched actin networks
    in cell migration and antigen presentation, the two most relevant processes in
    dendritic cell biology. Branched actin networks construct lamellipodial protrusions
    at the leading edge of migrating cells. These are typically seen as adhesive structures,
    which mediate force transduction to the extracellular matrix that leads to forward
    locomotion. We ablated Arp2/3 nucleation promoting factor WAVE in DCs and found
    that the resulting cells lack lamellipodial protrusions. Instead, depending on
    the maturation state, one or multiple filopodia were formed. By challenging these
    cells in a variety of migration assays we found that lamellipodial protrusions
    are dispensable for the locomotion of leukocytes and actually dampen the speed
    of migration. However, lamellipodia are critically required to negotiate complex
    environments that DCs experience while they travel to the next draining lymph
    node. Taken together our results suggest that leukocyte lamellipodia have rather
    a sensory- than a force transducing function. Furthermore, we show for the first
    time structure and dynamics of dendritic cell F-actin at the immunological synapse
    with naïve T cells. Dendritic cell F-actin appears as dynamic foci that are nucleated
    by the Arp2/3 complex. WAVE ablated dendritic cells show increased membrane tension,
    leading to an altered ultrastructure of the immunological synapse and severe T
    cell priming defects. These results point towards a previously unappreciated role
    of the cellular mechanics of dendritic cells in T cell activation. Additionally,
    we present a novel cell culture based system for the differentiation of dendritic
    cells from conditionally immortalized hematopoietic precursors. These precursor
    cells are genetically tractable via the CRISPR/Cas9 system while they retain their
    ability to differentiate into highly migratory dendritic cells and other immune
    cells. This will foster the study of all aspects of dendritic cell biology and
    beyond. '

  text: Although much is known about the physiological framework of T cell motility,
    and numerous rate-limiting molecules have been identified through loss-of-function
    approaches, an integrated functional concept of T cell motility is lacking. Here,
    we used in vivo precision morphometry together with analysis of cytoskeletal dynamics
    in vitro to deconstruct the basic mechanisms of T cell migration within lymphatic
    organs. We show that the contributions of the integrin LFA-1 and the chemokine
    receptor CCR7 are complementary rather than positioned in a linear pathway, as
    they are during leukocyte extravasation from the blood vasculature. Our data demonstrate
    that CCR7 controls cortical actin flows, whereas integrins mediate substrate friction
    that is sufficient to drive locomotion in the absence of considerable surface
    adhesions and plasma membrane flux.

  text: During metastasis, malignant cells escape the primary tumor, intravasate lymphatic
    vessels, and reach draining sentinel lymph nodes before they colonize distant
    organs via the blood circulation. Although lymph node metastasis in cancer patients
    correlates with poor prognosis, evidence is lacking as to whether and how tumor
    cells enter the bloodstream via lymph nodes. To investigate this question, we
    delivered carcinoma cells into the lymph nodes of mice by microinfusing the cells
    into afferent lymphatic vessels. We found that tumor cells rapidly infiltrated
    the lymph node parenchyma, invaded blood vessels, and seeded lung metastases without
    involvement of the thoracic duct. These results suggest that the lymph node blood
    vessels can serve as an exit route for systemic dissemination of cancer cells
    in experimental mouse models. Whether this form of tumor cell spreading occurs
    in cancer patients remains to be determined.

  text: Coordinated changes of cell shape are often the result of the excitable, wave-like
    dynamics of the actin cytoskeleton. New work shows that, in migrating cells, protrusion
    waves arise from mechanochemical crosstalk between adhesion sites, membrane tension
    and the actin protrusive machinery.
