Megjegyzések:	Activated platelets are key components in many arterialdisorders. P-selectin is an activation-dependentplatelet receptor, which is also identified in endothelialcells. Together with E- and L-selectin it constitutesthe selectin family. These transmembrane proteinshave continued to attract great interest as they supportrapid and reversible cell adhesion in flow systemsand thus play an essential role in multicellularinteractions during thrombosis and inflammation.Similarly to other lectins, selectins bind to differentglycoconjugates with varying affinities. Proteinligands, equipped with the appropriate carbohydrateand sulfate moieties for P-selectin binding, have beenidentified in normal peripheral blood leukocytes andseveral non-hematopoietic organs, as well as on cancercells. For diagnostic purposes, P-selectin can readilybe detected on the platelet surface by flowcytometry and by ELISA as a soluble ligand in theplasma. Along with other markers, these data can beused in the assessment of platelet activation status.Such results bear clinical significance since P-selectinhas been implicated in the pathogenesis of widespreaddisorders including coronary artery disease,stroke, diabetes and malignancy.

Cím:	P-selectin glycoprotein ligand-1 deficiency augments G-CSF induced myeloid cell mobilization / Kornél Miszti-Blasius, Szabolcs Felszeghy, Csongor Kiss, Ilona Benkő, Krisztina Géresi, Attila Megyeri, Zsuzsanna Hevessy, János Kappelmayer
Dátum:	2014
Megjegyzések:	The effect of G-CSF was investigated in P-selectin Glycoprotein Ligand-1 (PSGL-1) deficient (PSGL-1-/-) and wild-type (PSGL-1+/+) mice to establish the role of this mucin in myeloid cell mobilization. G-CSF activates tissue proteases that cleave adhesion molecules, thus enhances the mobilization of myeloid cells and haematopoietic stem cells. Cytopenia was induced with a single dose of cyclophosphamide. In PSGL-1-/- animals, we observed a delayed extravasation of mature myeloid cells from the peripheral vessels into the tissue compartments and their faster mobilization from the bone marrow. Subsequently, animals received G-CSF twice a day for four days. Neutrophil and monocyte counts increased upon completion of G-CSF treatment and both values were significantly higher in PSGL-1-/- mice; 47.7 G/L vs. 28.3 G/L for neutrophils and 4.1 G/L vs. 2.0 G/L for monocytes. The ratio of atypical myeloid cells was also elevated. Analyzing the causes of the above differences, we identified a 4-fold increase in the colony forming unit (CFU-GM) counts of the peripheral blood in PSGL-1-/- mice, compared to wild type animals. A significantly elevated number of CFU-GM was detected also in the femurs of PSGL-1-/- mice, 4 and 5 days after cyclophosphamide treatment and these values paralleled with the elevation of CD34+/CD117+ stem cell counts in the peripheral blood. Our data suggest, that in the absence of PSGL-1, G-CSF was more potent in elevating absolute myeloid cell numbers by acting on cell release from the bone marrow, maturation from circulating precursor cells in the peripheral blood and prolonged retainment in the circulation.
