Key result
Platelets prevent iNOS protein expression early (6-48 hours) after endothelial balloon damage in rat carotid arteries, an effect reversible by platelet depletion or GP IIb/IIIa blockers.
Why the study?
Does platelet depletion or GP IIb/IIIa blockade increase early iNOS protein expression after endothelial denudation in rat carotid arteries?

Suggests endothelial cells suppress iNOS after injury in rats; leaves open relevance to human vascular disease.
Does platelet depletion or GP IIb/IIIa blockade increase early iNOS protein expression after endothelial denudation in rat carotid arteries?
Platelets play a crucial role in preventing early iNOS protein expression after endothelial balloon damage, an effect reversible by GP IIb/IIIa blockers.
González-Fernández et al. (1998) studied Endothelial denudation. Endothelial denudation and platelet depletion or GP IIb/IIIa blockade vs. Right carotid artery (control) and normal platelet function was evaluated on iNOS protein expression. Platelets prevent iNOS protein expression early (6-48 hours) after endothelial balloon damage in rat carotid arteries, an effect reversible by platelet depletion or GP IIb/IIIa blockers.
