Abstract:
Abstract Inflammation and infection are known to alter platelet count, production, and function and major studies have demonstrated that acute infection is associated with a transient 5-fold increased risk of thrombotic vascular syndromes including stroke, acute myocardial infarction, and peripheral vascular occlusion. Platelets play an intricate role in thrombosis, myocardial infarction, and thrombotic stroke and are now being appreciated for their functional innate immune receptors. More recently, platelets have been connected to the host's immune system via their ability to trap bacteria an

Abstract:
Platelets contain and release large amounts of 5-hydroxytryptamine that can influence the function of vascular adrenergic nerves. The immediate effect on neuronal function of low concentrations of the amine is to inhibit norepinephrine release. 5-Hydroxytryptamine may also be accumulated by the same uptake mechanism that reaccumulates norepinephrine into the adrenergic nerve endings. In diseased blood vessels where platelet aggregation occurs, 5-hydroxytryptamine may therby assume an alternative transmitter role, altering the function of the sympathetic nerves.

Abstract:
The ability of platelets to form stable adhesion contacts with other activated platelets (platelet cohesion or aggregation) at sites of vascular injury is essential for hemostasis and thrombosis. In this study, we have examined the mechanisms regulating cytosolic calcium flux during the development of platelet–platelet adhesion contacts under the influence of flow. An examination of platelet calcium flux during platelet aggregate formation in vitro demonstrated a key role for intercellular calcium communication (ICC) in regulating the recruitment of translocating platelets into developing aggr

Abstract:
SummaryThere is emerging evidence that platelets have an important role in inflammation beyond their involvement in hemostasis. Platelets can contribute to inflammatory reactions via crosstalk both with immune cells and endothelial cells. Inflamed vessels are characterized by the presence of activated endothelial cells. These activated endothelial cells upregulate receptors necessary for leukocyte recruitment, but also for the adhesion of platelets. Subsequently, immune cells can bind to platelets through adhesion receptors presented on the platelet surface, thus supporting leukocyte recruitme

Abstract:
Platelet-derived growth factor (PDGF) is a polypeptide growth factor first discovered in, and purified from, human blood platelets. As assayed by its ability to stimulate proliferation of cultured vascular smooth muscle cells, PDGF is the major mitogen in human whole blood serum. PDGF has also been reported to be chemotactic for fibroblasts, vascular smooth muscle cells, and leukocytes, and to be able to stimulate contraction of arterial smooth muscle. This, spectrum of activities suggests that PDGF could play a significant role in several vascular processes, including wound repair and the for

Abstract:
The treatment of patients suffering from unstable angina (UA) with antiplatelet drugs is a therapeutic approach that provided interesting results.Patients given aspirin, that inhibits cyclooxigenase pathway (CP) showed a significant reduction of cardiovascularevents.Quite surprisingly sulfinpirazone, that possesses a mechanism of action similar to aspirin, did not influence cardiovascular complications of UA patients.To further investigate the role of platelets in UA patients, we planned to study if ticlopidine (T), that inhibits platelet function by blocking fibrinogen binding to platelets, i

Abstract:
It has been described by several authors that a critical stenosis of a dog coronary artery causes cyclical blood flow variations (CBFV), which are caused by platelet plugging of the vessel. Little information is available on the mechanism of thrombus formation in a stenotized peripheral artery and on the pharmacological control of this phenomenon. Male beagle dogs were anesthetized with sodium pentobarbital, artificially ventilated and prepared for the recording of arterial pressure, heart rate and femoral blood flow.
