Linking Amyloid and Tau Pathology in Alzheimer’s Disease: The Role of Membrane Cholesterol in A -Mediated Tau Toxicity

P135: The Role of Amyloid Beta-Peptides and Tau Protein in Alzheimer\'s Disease

Alzheimer's desease is the most common age-related neurodegenerative disorder, and cognitive problems such as defects in learning and memory are of its symptoms.  Among the factors involved in the pathogenesis of the disease are biochemical disorders in protein production, oxidative stress, decreased acetylcholine secretion and inflammation of the brain tissue. Extra-neuronal accumulation ...

P 62: Markers of Neuroinflammation Related to Alzheimer\'s Disease Pathology in the Elderly

Alzheimer Disease (AD) is a neurodegenerative disorder and the most common form of dementia. Increasing evidence suggests that Alzheimer's disease pathogenesis is not restricted to the neuronal compartment, but includes strong interactions with immunological mechanisms in the brain. In vitro and animal studies have linked neuroinflammation to Alzheimer's disease (AD) pathology. Studies on marke...

Dendritic Function of Tau Mediates Amyloid-β Toxicity in Alzheimer's Disease Mouse Models

Alzheimer's disease (AD) is characterized by amyloid-beta (Abeta) and tau deposition in brain. It has emerged that Abeta toxicity is tau dependent, although mechanistically this link remains unclear. Here, we show that tau, known as axonal protein, has a dendritic function in postsynaptic targeting of the Src kinase Fyn, a substrate of which is the NMDA receptor (NR). Missorting of tau in trans...

An update on the toxicity of Aβ in Alzheimer’s disease

Alzheimer's disease is characterized histopathologically by deposition of insoluble forms of the peptide Abeta and the protein tau in brain. Abeta is the principal component of amyloid plaques and tau of neurofibrillary tangles. Familial cases of AD are associated with causal mutations in the gene encoding the amyloid precursor protein, APP, from which the amyloidogenic Abeta peptide is derived...
