:
To study the intracellular signal transduction mechanisms of
platelet activating factor (PAF) induced platelet
P-selectin expression ... Human blood platelets were used to test the effect of
PAF induced
P-selectin expression using flow cytometry ... Pretreatment with egtazic acid ( EGTA ) 2 mmol.L-1 and 5,5'- dimethyl-bis- ( o-aminophenoxy ) -ethane-N, N,N ', N'-tetracetic acid ( BAPTA ) 200 mumol.L-1 to block Ca2+ influx or chelate the intracellular calcium, respectively, reduced
P-selectin expression in
response to
PAF [ ( 13.3 +/- 0.9 ) % and ( 16.8 +/- 1.9 ) % vs ( 47.5 +/- 1.3 ) % of PAF group, P < 0.01 ]
Li et al., Thromb Res 2003
:
In vitro stimulation with ADP, thrombin, or
PAF increased platelet
P-selectin expression and thus PLA formation, but these responses were not affected by aspirin
Guo et al., Zhongguo Shi Yan Xue Ye Xue Za Zhi 2005
:
The results showed that the expression of CD62P on platelats, the expression of CD11b on neutrophils and PLA formation were all increased by PAF and ADP ; the PAF receptor antagonists ( GB ) could obviously inhibit the expression of
CD62P , CD11b and PLA formation
induced by
PAF , but could not completely inhibit the activation of platelet and neutrophil, and the platelet-neutrophil cross talk ; GB could inhibit the expression of CD62P and CD11b induced by ADP, but could not conpletely inhibit the activation of platelet and neutrophli ; GB could not obviously inhibit the platelet-leucocyte aggregates mediated by ADP
Osborn et al., Am J Physiol Cell Physiol 2007
:
However, physiologically relevant pGSN concentrations inhibit
platelet activating factor (PAF) mediated
P-selectin expression by up to 77 % ( P < 0.0001 )
Elstad et al., J Immunol 1995
:
P-selectin did not directly
stimulate synthesis of the lipid autoacoid
platelet activating factor (PAF) ; however, incubation on immobilized P-selectin primed monocytes for increased synthesis of PAF in response to opsonized zymosan particles ...
P-selectin increased
PAF production by monocytes incubated with unopsonized zymosan particles that stimulate this response by interaction with the beta-glucan receptor
Ichikawa et al., Am J Physiol 1997
:
Our results indicate that xanthine may promote neutrophil-endothelial adhesion via a hydrogen peroxide- and
PAF mediated
P-selectin expression
