Tissue factor-bearing microparticles and thrombus formation.
Blood microparticles are vesicular structures with a diameter of 100 to 1000 nm that are present in the blood of normal subjects and in patients with various diseases. These microparticles are derived from cells that circulate in the blood and cells associated with the blood vessel wall. Microparticle membranes retain the protein receptors of their parent cells and may retain RNAs and other cyt...
متن کاملIncreased risk of gestational vascular complications in women with low free tissue factor pathway inhibitor plasma levels out of pregnancy.
Tissue factor pathway inhibitor (TFPI) plays a crucial role in haemostasis by regulating TF-induced initiation of coagulation. Since it is expressed by endothelial and trophoblastic cells, TFPI is of particular importance at the placental level and might be involved in the occurrence of gestational vascular complications (GVC). In the present study, we investigated plasma free TFPI antigen in f...
متن کاملA low balance between microparticles expressing tissue factor pathway inhibitor and tissue factor is associated with thrombosis in Behçet’s Syndrome
Thrombosis is common in Behçet's Syndrome (BS), and there is a need for better biomarkers for risk assessment. As microparticles expressing Tissue Factor (TF) can contribute to thrombosis in preclinical models, we investigated whether plasma microparticles expressing Tissue Factor (TF) are increased in BS. We compared blood plasma from 72 healthy controls with that from 88 BS patients (21 with ...
متن کاملTissue factor pathway inhibitor: structure-function.
TFPI is a multivalent, Kunitz-type proteinase inhibitor, which, due to alternative mRNA splicing, is transcribed in three isoforms: TFPIalpha, TFPIdelta, and glycosyl phosphatidyl inositol (GPI)-anchored TFPIbeta. The microvascular endothelium is thought to be the principal source of TFPI and TFPIalpha is the predominant isoform expressed in humans. TFPIalpha, apparently attached to the surface...
متن کاملBiology of tissue factor pathway inhibitor.
Recent studies of the anticoagulant activities of the tissue factor (TF) pathway inhibitor (TFPI) isoforms, TFPIα and TFPIβ, have provided new insight into the biochemical and physiological mechanisms that underlie bleeding and clotting disorders. TFPIα and TFPIβ have tissue-specific expression patterns and anticoagulant activities. An alternative splicing event in the 5' untranslated region al...
