Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils

open access: yesAdvanced Science, EarlyView.
We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet

Serotonin 5-HT1 Receptors Potentiate Histamine and Thrombin Stimulated Prostaglandin Synthesis in Endothelial Cells

open access: yes, 2001
SummaryThe ability of serotonin 5-HT1 receptors to increase vascular tone was previously found to be activated by vasoconstrictiors such as hista-mine.

Lyophilized Synthetic Platelets: In Vitro Characterization and in Vivo Evaluation in Mouse Thrombocytopenia Model

open access: yesAdvanced Science, EarlyView.
ABSTRACT Platelet transfusions to treat bleeding complications use donor‐derived platelets stored at room‐temperature, that have a shelf‐life of only 5–7 days due to bacterial contamination risks. Cold‐stored and freeze‐dried platelets are being investigated for extending shelf‐life, but these still have the inherent challenge of donor‐dependency.

The Regulation of the CNS Innate Immune Response Is Vital for the Restoration of Tissue Homeostasis (Repair) after Acute Brain Injury: A Brief Review

open access: yesInternational Journal of Inflammation, 2010
Neurons and glia respond to acute injury by participating in the CNS innate immune response. This involves the recognition and clearance of “not self ” pathogens and “altered self ” apoptotic cells.

TAK-442, a Direct Factor Xa Inhibitor, Inhibits Monocyte Chemoattractant Protein 1 Production in Endothelial Cells via Involvement of Protease-Activated Receptor 1

open access: yesFrontiers in Pharmacology, 2018
Oral blood coagulation inhibitors and their receptors, such as factor Xa (FXa), thrombin, and the thrombin receptor protease-activated receptor 1 (PAR1), are entered into clinical trials for acute coronary syndrome therapy; however, the results obtained ...

Cathepsin G and thrombin: evidence for two different platelet receptors

open access: yes, 1994
Neutrophil cathepsin G and thrombin, the only platelet agonists that are proteases, exhibit a mandatory requirement for catalytic activity to induce platelet aggregation and signal transduction. The thrombin receptor is a G-protein-coupled receptor which

Expression and function of thrombin receptors (PAR1, PAR3 and PAR4) in human umbilical vein endothelial cells: thrombin-mediated CX3CL1 expression

open access: yes, 2008
Upregulation of the inflammatory pathways is a major event in pathological condition. Thrombin, the key protease involved in coagulation process has been desribed as a potent activator of endothelial cells.

Dual‐Network Protein Hydrogels Promote Rapid Hemostasis and Immune‐Regulated Scarless Tissue Regeneration

open access: yesAdvanced Science, EarlyView.
A dual‐network protein hydrogel substantially improves hemostasis and scar‐free healing.The adaptive network maintains intimate tissue contact while providing strong wet adhesion, tunable mechanics, and controlled degradation. Concurrent ROS scavenging and M2 polarization suppress fibrotic pathways, preventing scar formation.

Induction of Tumor Necrosis Factor (TNF) Release from Subtypes of T Cells by Agonists of Proteinase Activated Receptors

open access: yesMediators of Inflammation, 2013
Serine proteinases have been recognized as playing an important role in inflammation via proteinase activated receptors (PARs). However, little is known about the influence of serine proteinases and PARs on TNF secretion from highly purified T cells.
