nervous system
• at 12 months, rare amyloid beta (Abeta) deposits are observed in the cortex, with occasional deposits in the molecular layer of hippocampus and frequent Abeta deposits in the hilus of the dentate gyrus; mice show 3-fold less Abeta in the brain relative to Tg(APPV717F)109Ili, Abca1-wild-type controls
• fibrillar Abeta plaques are frequently observed in cortex and hippocampus
• Abeta deposits are almost all diffuse, with little true amyloid
• very few clusters of reactive microglia are seen in brain

reproductive system
• 3-fold increased numbers of apoptotic cells in testes relative to controls
• tubules display atrophy with marked degenerative changes such as large increase in multinucleated giant cells and cells with condensed nuclei
• testes exhibit maturation arrest due to absence of mature products of spermatogenesis
• 50% reduction in testes mass relative to wild-type controls
• severe atrophy
• elongated spermatids and spermatozoa are absent in testes of mutant males

nervous system
• in 12-month old mice have frequent amyloid beta (Abeta) deposits in cortex and hippocampus including molecular layer of hippocampus
• almost no deposits are observed in hilus of dentate gyrus of hippocampus
• thioflavin-S positive fibrillar Abeta plaques are frequently observed in cortex and hippocampus at 12 months
• thioflavin-S positive plaques are associated with reactive microglia
• Apoe-containing lipoprotein particles secreted by astrocytes contain more lipid than those secreted by non-transgenic controls; lipoprotein fractions contain a greater ratio of cholesterol to Apoe

homeostasis/metabolism
N
• plasma levels of cholesterol including HDL-associated cholesterol and phospolipids, and Apoe are not significantly different from controls at 3 months
• thioflavin-S positive plaques are associated with reactive microglia
• in 12-month old mice have frequent amyloid beta (Abeta) deposits in cortex and hippocampus including molecular layer of hippocampus
• almost no deposits are observed in hilus of dentate gyrus of hippocampus
• thioflavin-S positive fibrillar Abeta plaques are frequently observed in cortex and hippocampus at 12 months
• mice show 40% reduction in Apoe levels in hippocampus at 3 months; in CSF, levels of Apoe are decreased >40%
• brain lysates contain significantly lower levels of Clusterin than control samples

endocrine/exocrine glands
• 3-fold increased numbers of apoptotic cells in testes relative to controls
• tubules display atrophy with marked degenerative changes such as large increase in multinucleated giant cells and cells with condensed nuclei
• testes exhibit maturation arrest due to absence of mature products of spermatogenesis
• 50% reduction in testes mass relative to wild-type controls
• severe atrophy
