From Patients to Platelets and Back Again: Pharmacological Approaches to Glycoprotein VI, a Thrilling Antithrombotic Target with Minor Bleeding Risks

Nikolaos Stergiopoulos, Augusto Martins Lima

Despite significant advances in the treatment of thrombogenic diseases, antiplatelet therapies are still associated with a high bleeding risk. Consequently, potential benefits of preventing thromboembolic events by pharmacological agents need to be balance ...

Portable oxidative stress sensor: Dynamic and non-invasive measurements of extracellular H2O2 released by algae

Olivier Martin, Christian Santschi, Volodymyr Koman

Reactive oxygen species (ROS) generated by aerobic organisms are essential for physiological processes such as cell signaling, apoptosis, immune defense and oxidative stress mechanisms. Unbalanced oxidant/antioxidant budgets are involved in many diseases a ...

The Molecular Mechanism of the Catalase-like Activity in Horseradish Peroxidase

Ursula Röthlisberger, Pablo Campomanes Ramos

Horseradish peroxidase (HRP) is one of the most relevant peroxidase enzymes, used extensively in immunochemistry and biocatalysis applications. Unlike the closely related catalase enzymes, it exhibits a low activity to disproportionate hydrogen peroxide (H ...

Insights into the antiatherogenic molecular mechanisms of andrographolide against Porphyromonas gingivalis-induced atherosclerosis in rabbits

Amer Ashrafi

Atherosclerosis is the commonest and most important vascular disease. Andrographolide (AND) is the main bioactive component of the medicinal plant Andrographis paniculata and is used in traditional medicine. This study was aimed to evaluate the antiatherog ...

Lipid Receptor S1P(1) Activation Scheme Concluded from Microsecond All-Atom Molecular Dynamics Simulations

Shuguang Yuan

Sphingosine 1-phosphate (S1P) is a lysophospholipid mediator which activates G protein-coupled sphingosine 1-phosphate receptors and thus evokes a variety of cell and tissue responses including lymphocyte trafficking, endothelial development, integrity, an ...

Biophotonic tool for sensing the dynamics of H2O2 extracellular release in stressed cells

Olivier Martin, Christian Santschi, Shourya Dutta Gupta

Hydrogen peroxide (H2O2) is known to play a multifaceted role in cell physiology mechanisms involving oxidative stress and intracellular signal transduction. Therefore, the development of analytical tools providing information on the dynamics of H2O2 gener ...

The Intestinal Epithelium

Luca Pellegrinet

The mammalian intestine is a prototype of a self-renewing organ. The rapid cellular turnover is supported by proliferating progenitors located in the intestinal crypt, which is also the stem cell location. Homeostasis of the intestinal epithelium has to be ...

Coordination of Myofibroblast Contraction in Vitro

Lysianne Follonier Castella

The aim of this thesis is to elucidate the common mechanisms that regulate myofibroblast contraction and intercellular communication, with a particular focus on the role of Ca2+ signalling. Synthesis and remodelling of collagenous matrix by myofibroblasts ...

IL-13 induces expression of CD36 in human monocytes through PPARgamma activation

Johan Auwerx, Walter Wahli

The class B scavenger receptor CD36 is a component of the pattern recognition receptors on monocytes that recognizes a variety of molecules. CD36 expression in monocytes depends on exposure to soluble mediators. We demonstrate here that CD36 expression is ...

A theoretical model of the cellular calcium dynamics and vasomotion in muscular arteries

Michèle Koenigsberger

Muscular arteries possess the ability to control actively their lumen by altering the tone of the smooth muscle cells of the arterial wall, a property which is vital for a large number of the hemodynamical functions of the body. Arterial contraction is due ...
