Platelet transforming growth factor-β1 induces liver sinusoidal endothelial cells to secrete interleukin-6

Balaphas, Alexandre ; Meyer, Jeremy ; Perozzo, Remo ; Zeisser-Labouebe, Magali ; Berndt, Sarah ; Turzi, Antoine ; Fontana, Pierre ; Scapozza, Leonardo ; Gonelle-Gispert, Carmen ; Bühler, Leo H.

The roles and interactions of platelets and liver sinusoidal endothelial cells in liver regeneration are unclear, and the trigger that initiates hepatocyte proliferation is unknown. We aimed to identify the key factors released by activated platelets that induce liver sinusoidal endothelial cells to produce interleukin-6 (IL-6), a cytokine implicated in the early phase of liver regeneration....

Platelet interactions with liver sinusoidal endothelial cells and hepatic stellate cells lead to hepatocyte proliferation

Meyer, Jeremy ; Balaphas, Alexandre ; Fontana, Pierre ; Morel, Philippe ; Robson, Simon C. ; Sadoul, Karin ; Gonelle-Gispert, Carmen ; Bühler, Léo

In: Cells, 2020, vol. 9, no. 5, p. 1243

Background: Platelets were postulated to constitute the trigger of liver regeneration. The aim of this study was to dissect the cellular interactions between the various liver cells involved in liver regeneration and to clarify the role of platelets. (2) Methods: Primary mouse liver sinusoidal endothelial cells (LSECs) were co-incubated with increasing numbers of resting platelets, activated...

Differential expression of CD31 and von Willebrand factor on endothelial cells in different regions of the human brain: potential implications for cerebral malaria pathogenesis

Mbagwu, Smart Ikechukwu ; Filgueira, Luis

In: Brain Sciences, 2020, vol. 10, no. 1, p. 31

Cerebral microvascular endothelial cells (CMVECs) line the vascular system of the brain and are the chief cells in the formation and function of the blood brain barrier (BBB). These cells are heterogeneous along the cerebral vasculature and any dysfunctional state in these cells can result in a local loss of function of the BBB in any region of the brain. There is currently no report on the...

Hypoxia enhances endothelial intercellular adhesion molecule 1 protein level through upregulation of arginase type II and mitochondrial oxidative stress

Liang, Xiujie ; Arullampalam, Prakash ; Yang, Zhihong ; Ming, Xiu-Fen

In: Frontiers in Physiology, 2019, vol. 10, p. -

Hypoxia plays a crucial role in the pathogenesis of cardiovascular diseases. Mitochondrial enzyme arginase type II (Arg-II) is reported to lead to endothelial dysfunction and enhance the expression of endothelial inflammatory adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1). In this study, we investigate the role of Arg-II in...

PECAM-1 stabilizes blood-brain barrier integrity and favors paracellular T-Cell diapedesis across the blood-brain barrier during neuroinflammation

Wimmer, Isabella ; Tietz, Silvia ; Nishihara, Hideaki ; Deutsch, Urban ; Sallusto, Federica ; Gosselet, Fabien ; Lyck, Ruth ; Muller, William A. ; Lassmann, Hans ; Engelhardt, Britta

In: Frontiers in immunology, 2019, vol. 10, p. 711

Breakdown of the blood-brain barrier (BBB) and increased immune cell trafficking into the central nervous system (CNS) are hallmarks of the pathogenesis of multiple sclerosis (MS). Platelet endothelial cell adhesion molecule-1 (PECAM-1; CD31) is expressed on cells of the vascular compartment and regulates vascular integrity and immune cell trafficking. Involvement of PECAM-1 in MS pathogenesis...

MAGI1 mediates eNOS activation and NO production in endothelial cells in response to fluid shear stress

Ghimire, Kedar ; Zaric, Jelena ; Alday-Parejo, Begoña ; Seebach, Jochen ; Bousquenaud, Mélanie ; Stalin, Jimmy ; Bieler, Grégory ; Schnittler, Hans-Joachim ; Rüegg, Curzio

In: Cells, 2019, vol. 8, no. 5, p. 388

Fluid shear stress stimulates endothelial nitric oxide synthase (eNOS) activation and nitric oxide (NO) production through multiple kinases, including protein kinase A (PKA), AMP-activated protein kinase (AMPK), AKT and Ca2+/calmodulin-dependent protein kinase II (CaMKII). Membrane-associated guanylate kinase (MAGUK) with inverted domain structure-1 (MAGI1) is an adaptor protein that...
