| Popis: | Recent evidence suggests that long-chain saturated fatty acids (i.e. stearic acid), produced on lipolysis of triglyceride-rich lipoproteins in the interface of circulating remnant particles provide a contact surface that activates the contact system of coagulation and subsequently activates factor VII. Increased level of circulating activated factor VII is probably of little consequence to a healthy individual with minimal expression of tissue factor in the vasculature. However, at a site of an atheromatous plaque or at a vascular injury site where there is tissue factor activity, increased circulating activated factor VII is expected to generate thrombin at a higher rate. Propagation of the prothrombotic environment will be facilitated on expression of additional tissue factor that is induced by the local increased concentration of thrombin. Thrombin with its receptor-mediated interactions with blood and vessel wall cells can signal inflammatory and proliferative responses such as those that occur in atheroma. |
