Alzheimer’s Disease (AD) is a progressive neurological disorder associated with cognitive and memory deficits. Accumulation of amyloid beta (Aβ) plaques is one of the major causes of AD. Therefore, inhibition of the plaque formation has been aimed to play a preventive role in the disease. Lavender, through some neuroprotective roles such as antioxidant effects, is known to be an effective c...
Neurological inflammatory diseases are developing rapidly. Different factors involved in the pathogenesis of these diseases. In this article, we discuss some of the mechanisms are dealt with. An aberrant procedure of beta-amyloid precursor protein (BAPP) to form neurotoxic beta-amyloid peptides and an accumulated insoluble polymer of beta –amyloid (BA) that forms the senile plaque. The ab...
Alzheimer's disease (AD) is a neurodegenerative disease biochemically characterized by aberrant protein aggregation, including amyloid beta (Aβ) peptide accumulation. Protein aggregates in the cell are cleared by autophagy, a mechanism impaired in AD. To investigate the role of autophagy in Aβ pathology in vivo, we crossed amyloid precursor protein (APP) transgenic mice with mice lacking autoph...
The tumor necrosis factor type 1 death receptor (TNFR1) contributes to apoptosis. TNFR1, a subgroup of the TNFR superfamily, contains a cytoplasmic death domain. We recently demonstrated that the TNFR1 cascade is required for amyloid beta protein (Abeta)-induced neuronal death. However, the function of TNFR1 in Abeta plaque pathology and amyloid precursor protein (APP) processing in Alzheimer's...
Anti-Aβ antibodies are being developed as potential treatments for Alzheimer's disease. Some have dose-limiting side effects and many do not robustly remove pre-existing amyloid plaques. In this issue of Neuron, DeMattos et al. (2012) demonstrate that an amyloid plaque-specific antibody removes existing Aβ aggregates without side effects.
The role for phosphorylated p38 mitogen-activated protein kinase [p-p38(MAPK)] in b-amyloid plaque deposition [a hallmark of Alzheimer’s disease (AD) pathology] remains ambiguous. We combined immunohistochemistry and stereological sampling to quantify the distribution of plaques and p-p38(MAPK)-immunoreactive (IR) cells in the sensorimotor cortex of 3-, 6and 10-month-old TgCRND8 mice. The aggre...

IMPORTANCE In vivo imaging of brain β-amyloid, a hallmark of Alzheimer disease, may assist in the clinical assessment of suspected Alzheimer disease. OBJECTIVE To determine the sensitivity and specificity of positron emission tomography imaging with flutemetamol injection labeled with radioactive fluorine 18 to detect β-amyloid in the brain using neuropathologically determined neuritic plaque...
