Inflammation plays an important role in the pathogenesis of Alzheimer's disease (AD). Overexpression of tumor necrosis factor-α (TNF-α) occurs in the AD brain. Recent clinical studies have shown that the anti-TNF-α therapy improves cognition function of AD patients rapidly. However, the underlying mechanism remains elusive. The present study investigates(More)
Recent studies indicated that angiotensin II (Ang II) receptor blockers could reduce neurotoxins-induced dopaminergic (DA) cell death, but the underlying mechanisms are still unclear. Given that endoplasmic reticulum (ER) stress plays a major role in rotenone-induced neuronal apoptosis, we investigated whether candesartan cilexetil, a selective and(More)
Accumulating evidence suggests that ischemic preconditioning (IPC) increases cerebral tolerance to the subsequent ischemic exposure. However, the underlying mechanisms are still not fully understood. In the present study, we tested the hypothesis that AMP-activated protein kinase (AMPK)-dependent autophagy contributed to the neuroprotection of IPC in rats(More)
BACKGROUND The activation of nuclear factor-kappa B (NF-κB) and NLRP3 inflammasome is involved in neuroinflammation, which is closely linked to Alzheimer's disease (AD). In vivo and in vitro studies have suggested that artemisinin shows antiinflammatory effects in inflammation-related diseases. However, the impacts of artemisinin on AD have not been(More)
As the most common type of neurodegenerative disease, Alzheimer's disease (AD) is characterized by the accumulation of amyloid-β peptide (Aβ) within the brain. Triggering receptor expressed on myeloid cells (TREM) 1 is an immune receptor expressed by mononuclear phagocytes including monocytes and microglia, coupling with TYRO protein tyrosine kinase binding(More)
As a novel risk gene for Alzheimer's disease (AD), triggering receptor expressed on myeloid cells 2 (TREM2) gene encodes a type I transmembrane receptor that is uniquely expressed by the microglia in the brain. Emerging evidence indicates a strong association between TREM2 and tau pathology in the cerebral spinal fluid or brain tissue of AD patients. In(More)
BACKGROUND The close relationship between epileptic seizure and Alzheimer's disease (AD) has been demonstrated in the past decade. Valproic acid, a traditional first-line antiepileptic drug, exerted protective effects in transgenic models of AD. It remains uncertain whether new antiepileptic drugs could reverse neuropathology and behavioral deficits in AD(More)
Amyloid beta peptide 1-15 (Aβ1-15) and its derivatives have attracted the attention of the scientific community as candidate vaccines for Alzheimer's disease (AD) immunotherapy. Recent studies suggested that Aβ1-42 modulated the immune system by inducing pro-inflammatory dendritic cells (DCs) with reduced antigen-presenting function. However, it remains(More)
Recent studies suggest that brain angiotensin II (Ang II), the major effector molecule of the renin-angiotensin system, is implicated in the pathogenesis of Alzheimer's disease (AD). However, it remains unknown whether activation or blockade of the angiotensin II type 1 receptor (AT1R) has an impact on the secretion of amyloid-β (Aβ), the key molecule in(More)
OBJECTIVE The aim of this study was to validate the reliability of the Chinese version of Addenbrooke's Cognitive Examination III (ACE-III) for detecting dementia. Furthermore, the present study compares the diagnostic accuracy of ACE-III with that of mini-mental state examination (MMSE). METHODS One hundred seventy-seven patients with dementia and 180(More)
