Production and metabolism of platelet-activating factor by human bone marrow cells
Platelet-activating factor (PAF) is a phospholipid mediator of inflammation present in the human bone marrow. Freshly isolated human mononuclear bone marrow cells and marrow stromal cell cultures produced PAF under calcium ionophore (2µM) and LPS (10 µg/ml) stimulation. By contrast M-CSF (1000 U/ml)...

description | Platelet-activating factor (PAF) is a phospholipid mediator of inflammation present in the human bone marrow. Freshly isolated human mononuclear bone marrow cells and marrow stromal cell cultures produced PAF under calcium ionophore (2µM) and LPS (10 µg/ml) stimulation. By contrast M-CSF (1000 U/ml), GM-CSF (100 ng/ml), IL1. IL3, IL6 and stem cell factor (10 ng/ml) did not stimulate PAF production. Marrow stromal cells produced 50-fold more PAF than freshly isolated mononuclear marrow cells, suggesting that stromal cells might be the major source of the human marrow-derived PAF. Mononuclear marrow cells and stromal cell cultures metabolized PAF with 1-alkyl-2-acyl-glycerophosphocholine as the major metabolic product. PMSF and
p-BPB decreased the catabolism of PAF by freshly isolated marrow cells, but not by stromal cell cultures. While stromal cells rather than haematopoietic progenitors might be a major source of the human bone-marrow-derived PAF, both cell types metabolize it, suggesting their putative role in the regulation of PAF concentration in the human bone marrow.
Le “platelet-activating factor” (PAF) est un médiateur phospholipidique présent dans la moelle osseuse humaine. Les cellules médullaires mono-nucléées fraîchement isolées et les cellules du stroma osseux produisent du PAF lors d'une stimulation par le calcium ionophore (2 µM) et le LPS (10 µg/ml). Par contre, le M-CSF (1000 U/ml), le GM-CSF (100 ng/ml), l'ILl, l'IL6 et le SCF (10 ng/ml) sont sans effet. Les cellules du stroma osseux produisent 50 fois plus de PAF que les cellules médullaires mononucléées, ce qui suggère leur rôle important dans la production du PAF médullaire. Ces deux catégories cellulaires dégradent le PAF en 1-alkyl analogue de phosphatidylcholine. L'ensemble de ces résultats suggère la participation des cellules mononucléées médullaires et celles du stroma osseux dans la régulation des taux de PAF dans la moelle. |
