Microvascular endothelial cells express a phosphatidylserine receptor: a functionally active receptor for phosphatidylserine-positive erythrocytes.
Phosphatidylserine (PS)-positive erythrocytes adhere to endothelium and subendothelial matrix components. While thrombospondin mediates these inter-actions, it is unknown whether PS-associated erythrocyte-endothelial adhesion occurs in the absence of plasma ligands. Using ionophore-treated PS-expressing control HbAA erythrocytes, we demonstrate that PS-positive erythrocytes adhered to human lun...

متن کاملPhosphatidylserine receptor is required for clearance of apoptotic cells.
Cells undergoing apoptosis during development are removed by phagocytes, but the underlying mechanisms of this process are not fully understood. Phagocytes lacking the phosphatidylserine receptor (PSR) were defective in removing apoptotic cells. Consequently, in PSR-deficient mice, dead cells accumulated in the lung and brain, causing abnormal development and leading to neonatal lethality. A fr...
متن کاملHuman vascular smooth muscle cells express functionally active endothelial cell protein C receptor.
The endothelial cell protein C receptor (EPCR) is expressed on endothelial cells and regulates the protein C anticoagulant pathway via the thrombin-thrombomodulin complex. Independent of its anticoagulant activity, activated protein C (APC) can directly signal to endothelial cells and upregulate antiapoptotic and antiinflammatory genes. Here we show that vascular smooth muscle cells (SMCs) also...
متن کاملPhosphatidylserine transport in Rhnull erythrocytes.
Phosphatidylserine transport in normal and Rhnull red blood cells was determined by measuring characteristic morphologic changes induced by synthetic phospholipids. Treating normal A+ cells with commercial anti-A antisera, anti-Rho(D) antisera, or with saturating concentrations of purified Rho(D) antibodies had no effect on phosphatidylserine transport. Normal B- cells treated with purified ant...
