Serotonin 61-65 presenilin 1 Mus musculus 190-193 15262269-1 2004 Transgenic mice expressing both mutant amyloid precursor protein (APPswe) and presenilin-1 (PS1DeltaE9) develop amyloid deposits as early as 4 months of age and preliminary evidence suggests that this may be associated with degenerative changes in serotonin axons innervating the dentate gyrus of the hippocampus. Serotonin 248-257 presenilin 1 Mus musculus 78-90 15262269-2 2004 In the present investigation, which focused on further delineating the effects of amyloid deposition on hippocampal neurochemistry, decreases in serotonin neurotransmitter levels (-25%) were discovered to be present at 18 months in APP+/PS1+ mice, while norepinephrine was reduced in the hippocampus of 12- (-30%) and 18-month-old (-45%) APP+/PS1+ double mutants. Serotonin 145-154 presenilin 1 Mus musculus 237-240 15262269-2 2004 In the present investigation, which focused on further delineating the effects of amyloid deposition on hippocampal neurochemistry, decreases in serotonin neurotransmitter levels (-25%) were discovered to be present at 18 months in APP+/PS1+ mice, while norepinephrine was reduced in the hippocampus of 12- (-30%) and 18-month-old (-45%) APP+/PS1+ double mutants. Serotonin 145-154 presenilin 1 Mus musculus 343-346 34924373-14 2022 The reduced viability of 3xTg-/-mice could indicate that 5-HT protects against the seizures that can impact the viability of APP/PS1 mice.
