Coagulation cascade

Ilaria Cavallari, Giuseppe Patti
Platelets and the coagulation cascade play key roles in initiation, amplification, and perpetuation of acute coronary syndromes (ACS). In the past few years, there has been great progress in ACS antithrombotic treatment with the introduction of novel anticoagulants (fondaparinux and bivalirudin), more potent P2Y12 inhibitors (prasugrel and ticagrelor) and protease-activated receptor antagonists (vorapaxar). Nonetheless, patients with ACS frequently have recurrent ischemic events despite the use of currently recommended dual antiplatelet therapy, revascularization procedures as appropriate, and other evidence-based secondary preventive measures...

Hematopoietic stem/progenitor cells (HSPCs) circulate in peripheral blood (PB) under normal conditions and their number increases in response to stress, inflammation, tissue/organ injury, and may increase up to 100-fold after administration of mobilization-inducing drugs. Mounting evidence suggests that mobilizing agent-induced mobilization of HSPCs from bone marrow into PB is a result of innate immunity-mediated sterile inflammation in the bone marrow (BM) microenvironment. A critical initiating role in this process is played by tissue/organ injury-mediated or pharmacologically induced release from bone marrow-residing granulocytes and monocytes of (i) danger-associated molecular patterns (DAMPs), (ii) reactive oxygen species (ROS), and (iii) proteolytic and lipolytic enzymes...

Objective: Cancer-associated inflammation and coagulation cascades play vital roles in cancer progression and survival. In this study, we investigated the significance of the combination of preoperative fibrinogen and the neutrophil-to-lymphocyte ratio (NLR) in predicting the survival of patients with non-small cell lung cancer (NSCLC). Methods: We retrospectively enrolled 589 patients with NSCLC who underwent surgery. The univariate and multivariate Cox survival analyses were used to evaluate the prognostic indicators, including the combination of fibrinogen and NLR (F-NLR)...

Tissue Factor is a cell-surface glycoprotein expressed in various cells of the vasculature and is the principal regulator of the blood coagulation cascade and hemostasis. Notably, aberrant expression of Tissue Factor is associated with cardiovascular pathologies such as atherosclerosis and thrombosis. Here, we sought to identify factors that regulate Tissue Factor gene expression and activity. Tissue Factor gene expression is regulated by various transcription factors, including activating protein-1 and nuclear factor-kappa B...

PURPOSE OF REVIEW: This review focuses on new clinical aspects of antiphospholipid syndrome (APS) in the last 5 years. RECENT FINDINGS: The pathogenesis of APS is related to endothelial activation by mechanisms other than autoantibody-mediated massive coagulation. These include Toll-like receptors, the m-TORC pathway, and neutrophil activation, inducing an uncontrolled inflammatory cascade. Given these new pathogenetic hypotheses, the treatment of APS could be directed towards a fine balance between anticoagulation and immunomodulation...

BACKGROUND: Fibrinogen is a central player in the blood coagulation cascade and one of the most abundant plasma proteins. This glycoprotein also triggers important events (e.g., cell spreading, the respiratory burst and degranulation) in neutrophil cells via a αM β2 integrin-mediated binding to the cell surface. Yet, little is known about the interaction of fibrinogen with leukocytes other than neutrophils or stimulated monocytes, although high amounts of fibrinogen protein can also be found in lymphocytes, particularly in T-cells...

A series of hyaluronic acid grafted pullulan (HA-g-Pu) polymers with different hyaluronic acid (HA) moieties degrees of substitution (DS) were synthesized and characterized by fourier transform infrared (FT-IR), proton nuclear magnetic resonance (1 H NMR) and differential scanning calorimetry measurement (DSC). Compared to pure HA, HA-g-Pu polymers obtained better anti-enzymatic degradation ability in vitro, and the degradation rate of HA-g-Pu polymers depended on their different DS of HA moieties. The HA-g-Pu films were made of leaf-shape cascading arrangement with many small porous ranging from 0 to 100 μm in diameter when observed by scanning electron microscopy (SEM)...

Background: IgA nephropathy (IgAN) is the most common primary glomerulonephritis diagnosed based on renal biopsy. Mesangial IgA deposits along with the proliferation of mesangial cells are the histologic hallmark of IgAN. Non-invasive diagnostic tools may help to prompt diagnosis and therapy. The discovery of potential and reliable urinary biomarkers for diagnosis of IgAN depends on applying robust and suitable models. Applying two multivariate modeling methods on a urine proteomic dataset obtained from IgAN patients, and comparison of the results of these methods were the purpose of this study...

BACKGROUND: Thromboelastography (TEG) provides a comprehensive evaluation of blood clot formation. This test can be used to identify abnormalities in coagulation by assessing multiple aspects of the clotting cascade, including the speed of clot initiation and formation, clot strength, and ultimately fibrinolysis. Thromboembolic disease has been hypothesized to play a role in the pathophysiology of cold stress syndrome (CSS), an important cause of mortality in the threatened Florida manatee (Trichechus manatus latirostris)...

: Complement and coagulation are evolutionarily related proteolytic cascades in the blood that are critical for effecting an appropriate innate response to injury that limits bleeding and infection, while promoting healing. Although often viewed as distinct, it has long been recognized that cross-talk likely exists between these pathways. Only recently have molecular links been established. These are providing insights that are revealing opportunities for the development of novel therapeutic strategies to better treat a wide range of thrombotic, inflammatory, immune, infectious, and malignant diseases...

Schizothorax prenanti (S. prenanti) is an indigenous fish species and is popularly cultured in southwestern China. In recent years, intensive farming of S. prenanti and water quality deterioration has increased the susceptibility of this fish to various pathogens, including Aeromonas hydrophila (A. hydrophila), which has caused severe damage to S. prenanti production. However, the understanding of molecular immune response of S. prenanti to A. hydrophila infection is still lacking. In order to better comprehend the S...

The choice of hemostat is determined by the situation and the degree of hemorrhage. One common hemostat, the nonwoven dressing, is easy to handled and controls severe bleeding on wider wounds. In this study, chitosan-based nonwoven dressings with recombinant batroxobin (rBat) were used as efficacious hemostatic dressing agents. Hemostatic agents need to absorb blood quickly in the early stages of blood coagulation cascade to rapidly and effectively control of excessive hemorrhages. To date, most studies of hemostatic agents focused on a single material and hemostats composed of multiple materials have not been studied sufficiently...

Some hemodialysis patients suffer from repeat dysfunction of dialysis vascular access and need procedures of angioplasty, thrombectomy, and even temporary catheter use. Why these patients are vulnerable to vascular access dysfunction and how to improve its patency are imperative to be discovered. Traditional risk factors for vascular access function had been widely investigated but could not fully explain this question. Several genotype polymorphisms were demonstrated to increase the incidence of cardiovascular disease and might also be linked to higher risk of vascular access dysfunction...

Atherosclerotic plaque rupture or erosion and subsequent development of platelet-containing thrombus formation is the fundamental cause of cardiovascular disease, which is the most common cause of death and disability worldwide. Here we show the high sensitivity of 200-270 GHz T-ray to distinguish thrombus formation at its early stage from uncoagulated blood. A clinical observational study was conducted to longitudinally monitor the T-ray absorption constant of ex-vivo human blood during the thrombus formation from 29 subjects...

BACKGROUND: Pre-eclampsia (PE) is related to an impaired endothelial function. Endothelial dysfunction accounts for altered vascular reactivity, activation of the coagulation cascade and loss of vascular integrity. Impaired endothelial function originates from production of inflammatory and cytotoxic factors by the ischemic placenta and results in systemic oxidative stress (OS) and an altered bioavailability of nitric oxide (•NO). The free radical •NO, is an endogenous endothelium-derived relaxing factor influencing endothelial function...

Despite significant improvements in injury prevention and emergency response, injury-related death and morbidity continues to increase in the US and worldwide. Patients with trauma, invasive operations, anti-cancer treatment, and organ transplantation produce a host of danger signals and high levels of pro-inflammatory and pro-thrombotic mediators, such as damage-associated molecular patterns (DAMPs) and extracellular vesicles (EVs). DAMPs (e.g., nucleic acids, histone, high-mobility group box 1 protein, and S100) are molecules released from injured, stressed, or activated cells that act as endogenous ligands of innate immune receptors, whereas EVs (e...
