N normal phenotype
behavior/neurological
N
• mice show improved performance day by day in both the escape latency and distance during the hidden platform trails of the Morris water maze compared to single Tg(APPSwFlLon,PSEN1*M146L*L286V)6799Vas expressing mice

homeostasis/metabolism
• mice show lower levels of both soluble and insoluble amyloid beta 42 in the brain than in single Tg(APPSwFlLon,PSEN1*M146L*L286V)6799Vas expressing mice
• however, expression of the precursor APP remains unaffected
• mice show a reduction of amyloid plaques in the cortex and a trend of reduction in the hippocampus
• short-term treatment of mice with SBI-0206965, an autophagy inhibitor blocking the kinase activity of an essential upstream kinase ULK1, abolishes the reduction in brain amyloid beta 42 levels

nervous system
• mice show lower levels of both soluble and insoluble amyloid beta 42 in the brain than in single Tg(APPSwFlLon,PSEN1*M146L*L286V)6799Vas expressing mice
