reproductive system
N
• homozygous females are viable and fertile

homeostasis/metabolism
• thrombi formed in response to FeCl3 injury are fragile and prone to rupture and to embolizing
• smaller thrombi with lower platelet density
• clotting times are normal

immune system
• increased microgliosis
• early onset of disease when infected with scrapie
• succumb to infection after 144 days as opposed to 184 days for controls
• symptoms of scrapie infection equivalent to 1000X higher dose

nervous system
• increased microgliosis
• more severe loss of parvalbumin positive neurons in the cortex as a result of scrapie infection than occurs in controls
• increased apoptosis
• vacuolation resulting from scrapie infection more pronounced than in controls

hematopoietic system
• increased microgliosis

cellular
• increased microgliosis
