Safe and effective antithrombotic therapy requires understanding of mechanisms that contribute to pathological thrombosis but have a lesser impact on hemostasis. We found that the extrinsic tissue factor (TF) coagulation initiation complex can selectively activate the antihemophilic cofactor, FVIII, triggering the hemostatic intrinsic coagulation pathway independently of thrombin feedback loops...
Hemorrhagic shock (HS) disrupts the endothelial cell barrier, resulting in microvascular hyperpermeability. Recent studies have also demonstrated that activation of the apoptotic signaling cascade is involved in endothelial dysfunction, which may result in hyperpermeability. Here we report involvement of the mitochondrial "intrinsic" pathway in microvascular hyperpermeability following HS in ra...
BACKGROUND Inhibition of blood coagulation appears to be an important therapeutic strategy to improve the outcome in sepsis. However, the beneficial effect of anticoagulant treatment in sepsis is solely based on experimental data using inhibitors of the extrinsic coagulant pathway. The role of the intrinsic pathway of coagulation in the pathogenesis of sepsis has not been explored yet. OBJECT...
Despite significant improvements in treatment, cure rates for many cancers remain suboptimal. The rise of cytotoxic chemotherapy has led to curative therapy for a subset of cancers, though intrinsic treatment resistance is difficult to predict for individual patients. The recent wave of molecularly targeted therapies has focused on druggable-activating mutations, and is thus limited to specific...
Activation of coagulation factor X via the intrinsic pathway requires the assembly of factors IXa and VIII on lipid membranes. It is known that the platelet expresses membrane sites for assembly of factors IXa/VIII and promotes efficient factor X activation. We now show that human blood monocytes, but not lymphocytes or polymorphonuclear leukocytes, also express appropriate sites for factors IX...
PURPOSE To determine whether the FAS-mediated apoptosis pathway becomes activated in the retina after retinal detachment and to investigate the temporal relationship between the activation of the FAS-pathway and the intrinsic apoptosis pathway involving caspase-9 and cytochrome c. METHODS Experimental retinal detachments were created in Brown-Norway rats by injecting 10% hyaluronic acid into ...
