  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: 'In contrast to lymph nodes, the lymphoid regions of the spleen—the white
    pulp—are located deep within the organ, yielding the trafficking paths of T cells
    in the white pulp largely invisible. In an intravital microscopy tour de force
    reported in this issue of Immunity, Chauveau et al. show that T cells perform
    unidirectional, perivascular migration through the enigmatic marginal zone bridging
    channels. '
