dc.description.abstractAlzheimer's disease (AD) is characterized by the age-related deposition of β-amyloid (Aβ) 40/42 peptide aggregates in vulnerable brain regions. Multiple levels of evidence implicate a central role for Aβ in the pathophysiology of AD. Aβ is generated by the regulated cleavage of a = 700 amino acid Aβ precursor protein (βAPP). Full-length βAPP can undergo proteolytic cleavage either within the Aβ domain to generate secreted sβAPPα or at the N-terminal and C-terminal domain(s) of Aβ to generate amyloidogenic Aβ peptides. Several epidemiological studies have reported that estrogen replacement therapy protects against the development of AD in postmenopausal women. The aim of this study was to elucidate the antioxidant neuroprotective mechanism of Bombusae concretio Salicea (BC). BC was effective protectants against oxidative glutamate toxicity in the murine neuroblastoma cells (N2a) and human neuroblastoma cells (SK-N-MC). BC exhibited similar protective properties against oxidative glutamate toxicity and H2O2 toxicity. BC exhibited an antioxidant activity at approximately 20 μg/ml. BC of 5 μg/ml was ineffective in preventing the oxidative modification of LDL. The half-maximal effective concentration for BC was 16 μg/ml. These results suggested that BC supplementation in elderly men may be protective in the treatment of Alzheimer's disease (AD). We report here that treatment with BC increases the secretion of the nonamyloidogenic APP fragment, sβAPPα and decreases the secretion of Aβ peptides from N2a cells and rat primary cerebrocortical neurons. These results raise the possibility that BC supplementation in elderly men may be protective in the treatment of AD.-
