Deciphering Alzheimer's disease: the amyloid precursor protein yields new clues.

The neighborhood of Alzheimer's amyloid precursor protein: new clues on Alzheimer's pathology from other proteins linked to amyloid plaque formation

The identification of amyloid-rich plaques has long been a diagnostic tool for pathologists investigating Alzheimer's disease (AD). The plaques are formed through the accumulation and aggregation of beta-amyloid peptides derived from the amyloid precursor protein (APP; see figure) and are characteristically found in the brain parenchyma and around blood vessels. Although it is clear that APP pl...

Deciphering the genesis and fate of amyloid beta-protein yields novel therapies for Alzheimer disease.

Alzheimer's disease: genes, proteins, and therapy.

Rapid progress in deciphering the biological mechanism of Alzheimer's disease (AD) has arisen from the application of molecular and cell biology to this complex disorder of the limbic and association cortices. In turn, new insights into fundamental aspects of protein biology have resulted from research on the disease. This beneficial interplay between basic and applied cell biology is well illu...

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 ...

Cholinergic neuropathology in a mouse model of Alzheimer's disease

Transgenic mice over-expressing mutant human amyloid precursor protein (PDAPP mouse) develop several Alzheimer’s disease (AD)-like lesions including an age-related accumulation of amyloid-?-containing neuritic plaques. Although aged, heterozygous PDAPP mice also exhibit synaptic and glial cell changes, that is characteristic of AD pathology, no evidence of neurodegeneration has been observed. T...
