  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: 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: 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

  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: 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: 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: 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.

  text: 'Platelets are central players in thrombosis and hemostasis but are increasingly
    recognized as key components of the immune system. They shape ensuing immune responses
    by recruiting leukocytes, and support the development of adaptive immunity. Recent
    data shed new light on the complex role of platelets in immunity. Here, we summarize
    experimental and clinical data on the role of platelets in host defense against
    bacteria. Platelets bind, contain, and kill bacteria directly; however, platelet
    proinflammatory effector functions and cross-talk with the coagulation system,
    can also result in damage to the host (e.g., acute lung injury and sepsis). Novel
    clinical insights support this dichotomy: platelet inhibition/thrombocytopenia
    can be either harmful or protective, depending on pathophysiological context.
    Clinical studies are currently addressing this aspect in greater depth.'

  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: 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: Blood platelets are critical for hemostasis and thrombosis and play diverse
    roles during immune responses. Despite these versatile tasks in mammalian biology,
    their skills on a cellular level are deemed limited, mainly consisting in rolling,
    adhesion, and aggregate formation. Here, we identify an unappreciated asset of
    platelets and show that adherent platelets use adhesion receptors to mechanically
    probe the adhesive substrate in their local microenvironment. When actomyosin-dependent
    traction forces overcome substrate resistance, platelets migrate and pile up the
    adhesive substrate together with any bound particulate material. They use this
    ability to act as cellular scavengers, scanning the vascular surface for potential
    invaders and collecting deposited bacteria. Microbe collection by migrating platelets
    boosts the activity of professional phagocytes, exacerbating inflammatory tissue
    injury in sepsis. This assigns platelets a central role in innate immune responses
    and identifies them as potential targets to dampen inflammatory tissue damage
    in clinical scenarios of severe systemic infection. In addition to their role
    in thrombosis and hemostasis, platelets can also migrate to sites of infection
    to help trap bacteria and clear the vascular surface.
