    Megakaryocyte emperipolesis mediates membrane transfer from intracytoplasmic neutrophils to platelets

    Pierre Cunin et al.
    In a novel cell-in-cell interaction termed emperipolesis, neutrophils routinely transit through the cytoplasm of bone marrow megakaryocytes to pass surface membrane to newly-generated hybrid platelets.

    Heparan sulfates are critical regulators of the inhibitory megakaryocyte-platelet receptor G6b-B

    Timo Vögtle et al.
    Heparan sulfates in the vessel wall bind and regulate signaling from the megakaryocyte/platelet-specific inhibitory receptor G6b-B, a critical regulator of platelet homeostasis.

    Hypoxic mitophagy regulates mitochondrial quality and platelet activation and determines severity of I/R heart injury

    Weilin Zhang et al.
    Mitophagy regulates mitochondrial quality and mediates extensive mitochondrial degradation in (patho-)physiological settings and is one of the key components of hypoxic preconditioning which protects the heart from ischemia/reperfusion injury.

    Epithelial cells supply Sonic Hedgehog to the perinatal dentate gyrus via transport by platelets

    Youngshik Choe et al.
    During development the Sonic Hedgehog protein is produced by epithelial structures and acts at a distance in the brain and perhaps in other organs.

    Neuronal integration in the adult mouse olfactory bulb is a non-selective addition process

    Jean-Claude Platel et al.
    Adult neurogenesis in the olfactory bulb is not a turnover system but represents a lifelong neuronal addition mechanism.

    Alternative RNA splicing in the endothelium mediated in part by Rbfox2 regulates the arterial response to low flow

    Patrick A Murphy et al.
    Transcriptome analysis reveals an alternative splicing program induced in the arterial endothelium under low-flow inflammatory conditions by platelet and macrophage recruitment and dependent upon the RNA-binding splice factor Rbfox2.

    Platelet-derived growth factor (PDGF) signaling directs cardiomyocyte movement toward the midline during heart tube assembly

    Joshua Bloomekatz et al.
    Studies in zebrafish and mouse implicate the PDGF signaling pathway in the communication between the endoderm and the myocardium that drives medial myocardial movement and thereby initiates cardiac morphogenesis.

    Mechano-redox control of integrin de-adhesion

    Freda Passam et al.
    Ligand binding, force and chemistry combine to control the function of a cell surface receptor.

    Cooperative unfolding of distinctive mechanoreceptor domains transduces force into signals

    Lining Ju et al.
    New biophysical methods and analyses visualize in real-time a chain of coordinated single-molecular events on a living cell, enabling the inner workings of a mechanoreceptor important to biology to be elucidated.

  10. Harnessing forces: an interview with Lining (Arnold) Ju

    On reading that the 21st century would be known as the century of biology, mechanical engineering graduate Lining (Arnold) Ju decided to pursue a PhD in biomedical engineering. He is currently a postdoc at the Heart Research Institute and a lecturer at the University of Sydney in Australia, where he studies how platelets sense mechanical forces and how problems in this process can lead to various blood diseases.
