Cryptic messages: is noncoagulant tissue factor reserved for cell signaling?
T issue factor (TF) is the principal initiator of blood clotting in response to vascular injury and in thrombotic disease (1). TF, an integral membrane protein, is normally excluded from the vascular compartment. Coagulation is initiated when TF is exposed to zymogen coagulation proteases in plasma upon vascular damage. TF first binds factor VII, supporting both its activation to VIIa and activ...
متن کاملDisulfide isomerization switches tissue factor from coagulation to cell signaling.
Cell-surface tissue factor (TF) binds the serine protease factor VIIa to activate coagulation or, alternatively, to trigger signaling through the G protein-coupled, protease-activated receptor 2 (PAR2) relevant to inflammation and angiogenesis. Here we demonstrate that TF.VIIa-mediated coagulation and cell signaling involve distinct cellular pools of TF. The surface-accessible, extracellular Cy...
متن کاملStromal cell-derived factor 1/CXCR4 signaling is critical for early human T-cell development.
The present study investigated the potential role of stromal cell-derived factor 1 (SDF-1) in human intrathymic T-cell differentiation. Results show that SDF-1 is produced by human thymic epithelial cells from the subcapsular and medullary areas, and its receptor, CXCR4, is up-regulated on CD34(+) precursor cells committed to the T-cell lineage. Chimeric human-mouse fetal thymus organ culture (...

متن کاملThe gifts reserved for age.
Many disciplines from the biological and social sciences are relevant to the study of human ageing. The unique contribution of epidemiology lies in defining the phenomenon of ageing and identifying the influences that determine its manifestations. With sadness we recognise, wherever we look in the world, that these influences include privilege, prejudice, and politics. Ageing, in the sense of s...
