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 (PARs). Recent studies using various cell model systems and limited in vivo systems are beginning to define how TF-VIIa-induced signaling

In the present article, we review the emerging data on the mechanism of TF-mediated cell signaling and how it regulates various cellular responses, with particular focus on TF-VIIa protease-dependent signaling.
