Affinity purification of human tissue factor: interaction of factor VII and tissue factor in detergent micelles.
Tissue factor, a known initiator of blood coagulation, was found to be active in Triton X-100. A system consisting of tissue factor, factor VIIa, calcium ions, and coagulation factor X generated activated factor X at an appreciable rate. Based on this observation, we coupled human and bovine factor VII to a solid support. Each column bound tissue factor, solubilized in Triton X-100, in a specie...
متن کاملTissue factor-dependent autoactivation of human blood coagulation factor VII.
We recently showed that single-chain zymogen factor VII is converted to two-chain factor VIIa in an autocatalytic manner following complex formation with either cell-surface or solution-phase relipidated tissue factor apoprotein (Nakagaki, T., Foster, D. C., Berkner, K. L., and Kisiel, W. (1991) Biochemistry 30, 10819-10824). We have now performed a detailed kinetic analysis of the autoactivati...
متن کاملTHE ROLE OF ALVEOLAR MACROPHAGES IN THE PRODUCTION OF COLONY –STIMULATING FACTOR BY THE LUNG
The role of alveolar macrophages in the production of granulocyte/ macrophage colony-stimulating factor(s) by the rat lung was investigated. Lavaged lungs, when incubated at proper weight per volume of culture medium, produced the same amount of colony-stimulating factor as unlavaged ones. Both lavaged and unlavaged lungs produced similar types of colony-stimulating factor (s). Prolonged i...
متن کاملHuman alveolar macrophages synthesize factor VII in vitro. Possible role in interstitial lung disease.
Both fibrin and tissue macrophages are prominent in the histopathology of chronic inflammatory pulmonary disease. We therefore examined the procoagulant activity of freshly lavaged human alveolar macrophages in vitro. Intact macrophages (5 X 10(5) cells) from 13 healthy volunteers promoted clotting of whole plasma in a mean of 65 s. Macrophage procoagulant activity was at least partially indepe...
متن کاملJaundice and factor VII deficiency in newborn
Resistance to thyroid hormone is an uncommon condition. We report the clinical and laboratory findings of a case with both resistance to thyroid hormone and, a reduced capacity to produce and respond to thyroid hormone. RTH is a disorder characterized by elevated circulating thyroid hormones, state of non-suppressed pituitary TSH secretion and refractoriness to hormone action in peripheral tiss...
