Proteolytic inactivation of tissue factor pathway inhibitor by bacterial omptins.
The immune response to infection includes activation of the blood clotting system, leading to extravascular fibrin deposition to limit the spread of invasive microorganisms. Some bacteria have evolved mechanisms to counteract this host response. Pla, a member of the omptin family of Gram-negative bacterial proteases, promotes the invasiveness of the plague bacterium, Yersinia pestis, by activat...
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...

متن کاملProtein S stimulates inhibition of the tissue factor pathway by tissue factor pathway inhibitor.
Tissue factor (TF) plays an important role in hemostasis, inflammation, angiogenesis, and the pathophysiology of atherosclerosis and cancer. In this article we uncover a mechanism in which protein S, which is well known as the cofactor of activated protein C, specifically inhibits TF activity by promoting the interaction between full-length TF pathway inhibitor (TFPI) and factor Xa (FXa). The s...
