Regulation and functions of the protein C anticoagulant pathway.
The protein C pathway plays a critical role in the negative regulation of the blood clotting process. We recently identified an endothelial cell receptor for protein C/activated protein C (APC). The receptor is localized almost exclusively on endothelial cells of large vessels and is present at only trace levels or indeed absent from capillaries in most tissues. Patients with sepsis or lupus er...
متن کاملParticipation of endothelial cells in the protein C-protein S anticoagulant pathway: the synthesis and release of protein S
The protein C-protein S anticoagulant pathway is closely linked to the endothelium. In this paper the synthesis and release of the vitamin K-dependent coagulation factor protein S is demonstrated. Western blotting, after SDS PAGE of Triton X-100 extracts of bovine aortic endothelial cells grown in serum-free medium, demonstrated the presence of protein S. A single major band was observed at Mr ...
متن کاملEnhancement of rabbit protein S anticoagulant cofactor activity in vivo by modulation of the protein S C4B binding protein interaction.
The carboxy-terminal region of protein S has been recently been observed to be involved in the interaction between protein S and C4b-binding protein (Walker, F. J. 1989. J. Biol. Chem. 264:17645-17658). A synthetic peptide, GVQLDLDEAI, corresponding to that region of protein S has been used to investigate the protein S/C4b-binding protein interaction in vitro and in vivo. Rabbit activated prote...
متن کاملSpecies-specific anticoagulant and mitogenic activities of murine protein S.
BACKGROUND The protein C pathway down-regulates thrombin generation and promotes cytoprotection during inflammation and stress. In preclinical studies using models of murine injury (e.g., sepsis and ischemic stroke), murine protein S may be required because of restrictive species specificity. DESIGN AND METHODS We prepared and characterized recombinant murine protein S using novel coagulation...
