Canine platelets have been extensively studied but little is known about specific aspects such as adhesion. Platelet adhesion is a critical step during haemostasis and thrombosis as well as during inflammatory and immunopathogenic responses. The aim of this study was to evaluate the adhesive properties of canine platelets using fibrinogen and collagen as substrates immobilized on plates. Adhesion was monitored for 120 min and the effect of adenosine 50-diphosphate (ADP) was assayed. The results showed that canine platelets displayed good adhesion activity that was significantly time-dependent. Moreover, ADP was able to enhance platelet adhesion in a dose-dependent manner. The findings aid knowledge of the adhesion process and suggest a specific role of surface platelet receptors in mediating the interaction with extracellular matrix proteins.

Abstract

Canine platelets have been extensively studied but little is known about specific aspects such as adhesion. Platelet adhesion is a critical step during haemostasis and thrombosis as well as during inflammatory and immunopathogenic responses. The aim of this study was to evaluate the adhesive properties of canine platelets using fibrinogen and collagen as substrates immobilized on plates. Adhesion was monitored for 120 min and the effect of adenosine 50-diphosphate (ADP) was assayed. The results showed that canine platelets displayed good adhesion activity that was significantly time-dependent. Moreover, ADP was able to enhance platelet adhesion in a dose-dependent manner. The findings aid knowledge of the adhesion process and suggest a specific role of surface platelet receptors in mediating the interaction with extracellular matrix proteins.
