Alzheimer’s disease; APP processing; Cholesterol; Lipid raft; Rh2

Ginsenoside Rh2 (Rh2) is a ginseng derivative used in Chinese traditional medicine. We investigated whether Rh2 can help prevent Alzheimer’s disease symptoms and examined underlying mechanisms. We injected Rh2 into tg2576 Alzheimer’s disease model mice and looked for behavioral improvement and senile plaque reduction in brain slices. We measured amyloid precursor protein (APP) metabolism ... more

Alzheimer’s disease; Amyloid β protein; Axon; Curcumin; NGR

Curcumin has been widely used for the prevention and treatment of Alzheimer's disease (AD), but its mechanism is still not clear. Inhibitory factors of axonal regeneration have been shown to cause a series of pathophysiological changes in the early period of AD. In this study, the co-receptor (Nogo receptor; NgR) of three axonal growth-inhibitory proteins was examined, and effects of ... more

Alzheimer’s disease; Apolipoprotein E; Meta-analysis; Polymorphism; PPARγ

We investigated whether Pro12Ala (C→G) and His447His (C→T) polymorphisms of the peroxisome proliferator-activated receptor gamma (PPARγ) gene are associated with susceptibility to Alzheimer’s disease (AD). We conducted a meta-analysis of the associations between the PPARγ Pro12Ala and His447His polymorphisms and AD in subjects. The meta-analysis was performed according to the ... more

The objective of this study was to assess the associations of presenilin 1 (PS1) 1/2, angiotensin I-converting enzyme (ACE) insertion/deletion (I/D), and low-density lipoprotein receptor-related protein (LRP) C/T polymorphisms with the risk of Alzheimer’s disease (AD) in the Chinese population. PS1 1/2, ACE I/D, and LRP C/T, which are commonly investigated polymorphisms, were evaluated to ... more

Alzheimer’s disease; Meta-analysis; MicroRNA; Oxidized low density lipoprotein receptor 1; Polymorphism

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that contributes to dementia in the elderly population. Genome-wide linkage analysis has identified chromosome 12p as the AD-susceptible region, which includes lectin-like oxidized low-density lipoprotein receptor 1 (OLR1). The OLR1 +1073 C/T single-nucleotide polymorphism is located in the 3'- ... more

Alzheimer’s disease; Amyloid C-terminal fragment; BACE1; Tau hyperphosphorylation

The amyloid C-terminal fragment (βCTF) of the amyloid precursor protein (APP) is the cleaved component of APP by beta secretase-1 (BACE1), which shows similar neurotoxicity as amyloid beta (Aβ) in many ways. Evidence suggested that in addition to Aβ, βCTF might also participate in the pathogenesis of Alzheimer’s disease (AD). In recent years, the relationship between βCTF processing and ... more

Alzheimer’s disease; Estrogen receptor; Meta-analysis; Polymorphism

The aim of this study was to explore whether estrogen receptor 1 (ESR1) PvuII and XbaI polymorphisms are associated with susceptibility to Alzheimer’s disease (AD). We conducted a meta-analysis of the associations between AD and ESR1 PvuII and XbaI polymorphisms as well as haplotypes of the ESR1 PvuII and XbaI polymorphisms. A ... more

This study aims to investigate the expression of neurotrophin-4/5 (NT-4/5) in the pallium and hippocampus in juvenile rats with intraventricular injection of Streptococcus pneumoniae. We used 40 SPF SD rats (3 weeks old, regardless of gender) in this study. We drew 50 μL cerebrospinal fluid, and then, we injected 50 μL normal saline and S. pneumoniae suspension (108 ... more

Blood occlusion; Hippocampus; Hypothermia; Ultrastructure; Vimentin

Previous studies have shown that selective cerebral profound hypothermia combined with antegrade cerebral perfusion can improve resistance to cerebral hypoxia-ischemia in monkeys. The aim of this study was to observe the effect of selective cerebral profound hypothermia on the ultrastructure and vimentin expression in monkey hippocampi after severe cerebral ischemia. Eight healthy adult ... more
