homeostasis/metabolism
• about a 4-fold increase in the plasma level of soluble SELP (J:51068)
• about a 2 fold increase in the total number of microparticles in the plasma compared to controls (J:125020)
• shorter plasma clotting time compared to controls
• excess deposition of fibrin when non-anticoagulated blood is passed through glass capillaries coated with fibrillar collagen type III
• however, no significant differences in fibrinogen levels are detected compared to controls

immune system
• no increase in the number of rolling leukocytes is seen after stimulation with a calcium ionophore
• however, in the absence of stimulation rolling is similar to controls
• at 2 h after peritoneal thioglycollate injection neutrophil influx is only 30% that of wild-type controls
• however, by 4 h after injection neutrophil numbers are similar to controls

cardiovascular system
• in all pulmonary endothelial cells and some brain microvascular endothelial cells the mutant protein is localized to the membrane rather than in Weibel-Palade bodies as in wild type cells
• however, in some endothelial cells from brain microvasculature the mutant protein is localized to Weibel-Palade bodies
• about a 50% reduction in average hemorrhagic lesion size following induced local Shwartzman reaction compared to wild-type controls

cellular
• no increase in the number of rolling leukocytes is seen after stimulation with a calcium ionophore
• however, in the absence of stimulation rolling is similar to controls

hematopoietic system
• no increase in the number of rolling leukocytes is seen after stimulation with a calcium ionophore
• however, in the absence of stimulation rolling is similar to controls
• at 2 h after peritoneal thioglycollate injection neutrophil influx is only 30% that of wild-type controls
• however, by 4 h after injection neutrophil numbers are similar to controls
