According to the hitherto accepted view, neutrophils kill ingested microorganisms by subjecting them to high concentrations of highly toxic reactive oxygen species (ROS) and bringing about myeloperoxidase-catalysed halogenation. We show here that this simple scheme, which for many years has served as a satisfactory working hypothesis, is inadequate. We find(More)
We investigated the membrane localization of CD95 in type I and type II cells, which differ in their ability to recruit and activate caspase-8. We found that CD95 was preferentially located in lipid rafts of type I cells, while it was present both in raft and non-raft plasma membrane sub-domains of type II cells. After stimulation, CD95 located in(More)
Myeloperoxidase-mediated chlorination is thought to be a necessary microbicidal mechanism. The H2O2 required for this process is generated by the NADPH oxidase. Staphylococcus aureus can also produce H2O2, which is not broken down by catalase negative organisms. It has been thought that this bacterial H2O2 can substitute for cellular H2O2 in the(More)
Polycythemia vera (PV) is a clonal myeloproliferative disorder characterized by excessive erythrocyte production. Most patients with PV harbor an activating JAK2 mutation, but the molecular links between this mutation and erythrocyte overproduction are unknown. The interaction between death receptors and their ligands contributes to the physiological(More)
BACKGROUND In vitro diagnostic (IVD) investigations are indispensable for routine patient management. Appropriate testing allows early-stage interventions, reducing late-stage healthcare expenditure (HCE). AIM To investigate HCE on IVDs in two developed markets and to assess the perceived value of IVDs on clinical decision-making. Physician-perceived HCE(More)
