Here, we show that xanthoceraside at doses of 0.08 and 0.32 mg/kg/d for 6 months significantly improved learning and memory impairment in APP transgenic mice assessed by the Y maze and novel object recognition tests.
In contrast, C57 APP/PS1 and SAMP8 wild type mice were inconspicuous in all of these tasks and properties except C57 APP/PS1 mice which showed motor memory impairment in the shuttle box task at 9 months old.
Here we aimed to determine whether chronic treatment with the α(2)-adrenoceptor antagonist fluparoxan, that enhances noradrenaline release, can prevent the onset of Alzheimer's-like pathology and memory deficits in APP/PS1 transgenic mice (TASTPM).
SEN1500, an orally bioavailable and CNS-penetrant Aβ aggregation inhibitor, has previously been shown to reduce spatial learning and memory deficits in an APP transgenic mouse model.
Mice receiving endothelium-derived amyloid and tau proteins <i>via</i> intracerebroventricular injection exhibit a learning and memory deficit in object recognition, fear conditioning, and Morris water maze studies.
Here, we tested whether dietary choline supplementation throughout life reduces AD-like pathology and rescues memory deficits in the APP/PS1 mouse model of AD.
To investigate if increasing plasma apoA-I/HDL levels ameliorates AD-like memory deficits and amyloid-β (Aβ) deposition, we generated a line of triple transgenic (Tg) mice overexpressing mutant forms of amyloid-β precursor protein (APP) and presenilin 1 (PS1) as well as human apoA-I (AI).
This paper reports the case of a 38-year-old female showing early memory impairment and having a base pair mutation from guanine (G) to cytosine (C) at codon 139 of PSEN1, which leads to the substitution of a methionine with an isoleucine.
FGF2 treatment attenuated spatial memory deficits, reduced amyloid-β (Aβ) and tau pathologies, decreased inducible nitric oxide synthase expression, and increased the number of astrocytes in the dentate gyrus in APP 23 mice compared with the vehicle-treated controls.
Selective deletion of apolipoprotein E in astrocytes ameliorates the spatial learning and memory deficits in Alzheimer's disease (APP/PS1) mice by inhibiting TGF-β/Smad2/STAT3 signaling.
Amyloid-β peptide 42 (Aβ42) is produced through the sequential proteolytic cleavage of APP by β- and γ-secretase and causes the synaptic dysfunction associated with memory impairment in Alzheimer's disease.
We show that treatment aimed at preventing PV interneurons from becoming hyperexcitable is sufficient to restore PV interneuron properties to wild-type levels, reduce inhibitory input onto pyramidal cells, and rescue memory deficits in APP/PS1 mice.
Here, we demonstrated that HFD markedly deteriorated memory impairment and increased β-amyloid (Aβ) oligomers as well as Aβ deposition in amyloid precursor protein (APP) transgenic mice, which was reversed by exposure to an enriched environment for 10 weeks, despite the continuation of HFD.
These findings show a selective upregulation of astroglial B1R in the APP mouse brain, and the capacity of the B1R antagonist to abrogate amyloidosis, cerebrovascular and memory deficits.
TEN has potential benefit in treating learning and memory deficits in APP/PS1 transgenic AD mice, and its effects may be associated with reversing AD pathology-induced neuronal apoptosis.
