homeostasis/metabolism
• decreased platelet life span in vivo resulting in increased turnover
• moderate decrease following activation with integrin alpha2bbeta3
• at low agonist concentrations (thromboxane A2 analog U46619, CRP, and collagen) with increased aggregate size
• however, aggregation is normal in response to thrombin and do not exhibit spontaneous aggregation upon addition of epinephrine
• upon agonist activation, platelets exhibit moderately increased secretion compared with control cells
• in response to thrombin and CRP, ATP release is strongly increased compared to in control cells
• however, cells exhibit normal serotonin release and numbers of alpha and dense granules
• accelerated arterial occlusive thrombus formation following ferric chloride-induced mesenteric arteriole injury

hematopoietic system
• increased platelet size determined by increased width
• reduced filopodia extension after adhesion of immobilized VWF
• however, mice exhibit normal formation and structure of filopodia and normal spreading morphology following activation with ADP or thrombin
• moderate
