That's because the boosted mice produced normal — rather than high — levels of the amyloid precursor proteins from which plaques are made.

«What's distinct here is a regulatory role whereby the prion protein inhibits production of amyloid beta peptide from its precursor protein,» says Millhauser.

On page 735, molecular biologists describe a new candidate for b - secretase, an elusive enzyme that is needed to free one end of b - amyloid from its larger precursor protein.

A plaque is an accumulation of proteins that are primarily made up of Amyloid beta (A-beta), a small structure that splits off from the Amyloid Precursor Protein (APP).

Classical hallmarks of Alzheimer's disease (AD) are a synaptic loss, cholinergic neuron death, and abnormal protein deposition, particularly of toxic amyloid - β peptide (Aβ) that is derived from amyloid - β protein precursor (AβPP) by the action of beta - and gamma - secretases.

Abstract: Classical hallmarks of Alzheimer's disease (AD) are a synaptic loss, cholinergic neuron death, and abnormal protein deposition, particularly of toxic amyloid - β peptide (Aβ) that is derived from amyloid - β protein precursor (AβPP) by the action of beta - and gamma - secretases.

Our microscopy studies with quantitative co-localization analysis revealed the presence of intraneuronal Aβ in transgenic rats, with an immunological signal that was clearly distinguished from that of the amyloid precursor protein (APP) and its C - terminal fragments (CTFs).

Using blood collected from elderly persons aged up to one hundred and demonstrating no cognitive impairment, the researchers isolated precisely those immune cells whose antibodies are able to identify toxic beta - amyloid plaques but not the amyloid precursor protein that is present throughout the human body and that presumably plays an important role in the growth of nerve cells.

Beta amyloid is a fragment of a protein snipped from another protein called amyloid precursor protein (APP).

The production of neurotoxic Aβ peptide results from the specific proteolytic processing of the amyloid precursor protein (APP).

Aβ results from the normal cleavage of amyloid precursor protein (APP), but its accumulation and aggregation into plaques represents the quintessential feature of AD.27 Aβ is found in orders of magnitude greater in AD brains than in healthy brains.28 This fact is noteworthy because lower concentrations of Aβ tend to stay soluble; higher concentrations form plaques more readily.29
