Probing the interface between factor Xa and tissue factor in the quaternary complex tissue factor–factor VIIa–factor Xa–tissue factor pathway inhibitor [PDF]

open access: yesEuropean Journal of Biochemistry, 2003
Blood coagulation is triggered by the formation of a complex between factor VIIa (FVIIa) and its cofactor, tissue factor (TF). TF–FVIIa is inhibited by tissue factor pathway inhibitor (TFPI) in two steps: first TFPI is bound to the active site of factor Xa (FXa), and subsequently FXa–TFPI exerts feedback inhibition of TF–FVIIa.

Small cell lung cancer: circulating tumor cell lines and expression of mediators of angiogenesis and coagulation

open access: yesExploration of Targeted Anti-tumor Therapy, 2023
Aim: Coagulation is frequently activated in cancer patients and has been correlated with an unfavorable prognosis. To evaluate whether a putative release of tissue factor (TF) by circulating tumor cells (CTCs) represents a target to impair the ...

Platelets and tissue factor [PDF]

open access: yesPlatelets, 2005
Tissue factor (TF) is the most important initiator of intravascular coagulation. This article will review published evidence on the contribution of platelets to TF exposure to the circulating blood. The following mechanisms will be discussed: decryption of monocyte TF by platelets, contribution of platelets to TF expression in leukocytes, platelet ...

Regulation of Proinflammatory Molecules and Tissue Factor by SARS-CoV-2 Spike Protein in Human Placental Cells: Implications for SARS-CoV-2 Pathogenesis in Pregnant Women

open access: yesFrontiers in Immunology, 2022
SARS-CoV-2 infects cells via binding to ACE2 and TMPRSS2, which allows the virus to fuse with host cells. The viral RNA is detected in the placenta of SARS-CoV-2-infected pregnant women and infection is associated with adverse pregnancy complications ...

Kawasaki-like diseases and thrombotic coagulopathy in COVID-19: delayed over-activation of the STING pathway?

open access: yesEmerging Microbes and Infections, 2020
We previously made the hypothesis that STING contributes to COVID-19. The present review detail new arguments for over-activation of STING pathways in COVID-19, following the description of hyper-coagulability and Kawasaki-like diseases in children ...

Synthesis and analysis of small molecules to restrain the function of tissue factor within tumour cells

open access: yesFrontiers in Bioscience-Landmark, 2021
Introduction: The restriction of prolyl-protein cis/trans isomerase 1 (Pin1) activity has been shown to prevent the release of tissue factor (TF) leading to the accumulation of the latter protein within the cell.

Excess of heme induces tissue factor-dependent activation of coagulation in mice

open access: yesHaematologica, 2015
An excess of free heme is present in the blood during many types of hemolytic anemia. This has been linked to organ damage caused by heme-mediated oxidative stress and vascular inflammation.

Activation of TF-Dependent Blood Coagulation Pathway and VEGF-A in Patients with Essential Thrombocythemia

open access: yesMedicina, 2019
Background and objectives: Recent studies suggest that a vascular endothelial growth factor (VEGF-A) may be involved in the thrombotic process by stimulating the expression of tissue factor in vascular endothelial cells.

Inhibitors of Factor VIIa/Tissue Factor [PDF]

open access: yesArteriosclerosis, Thrombosis, and Vascular Biology, 2007
The formation of the proteolytic complex composed of the serine protease Factor VIIa and the cell-associated glycoprotein tissue factor (FVIIa/TF) initiates a cascade of amplified zymogen activation reactions leading to thrombus formation. The critical role of the coagulation cascade in pathological thrombosis has been the basis for significant efforts

Tissue Factor–Factor VIIa Signaling [PDF]

open access: yesArteriosclerosis, Thrombosis, and Vascular Biology, 2005
How does tissue factor (TF), whose principle role is to support clotting factor VIIa (FVIIa) in triggering the coagulation cascade, affect various pathophysiological processes? One of the answers is that TF interaction with FVIIa not only initiates clotting but also induces cell signaling via activation of G-protein–coupled protease activated receptors
