—Preceding unsigned comment added by 152.3.178.172 05:28, 2 April 2008 (UTC) The normal function of Aβ is unknown. Mice with Aβ precursor protein knocked out show various abnormalities, indicating that it may have a normal role. Aβ42 is present in normal patients but in Alzheimer's disease it is increased relative to Aβ40.

Aggregation, impaired degradation and immunization ...

The rate of aggregate growth depends on the availability of Aβ dimers (AbDim) and/or monomers (Abeta). The rate law must also contain the species AbP (aggregates) so that aggregates cannot grow unless AbP is greater than zero (if AbP = 0, then the rate of aggregate growth must also equal zero).

Inhibition and Mechanism of Amyloid Beta-Aggregation ...

Biochemical studies suggest that the longer, 42-residue Abeta (1-42) is more pathogenic than the shorter, 40-residue Abeta (1-40), due to its greater in vitro tendency to aggregate and precipitate as amyloid. Nonetheless, a molecular basis for the greater pathogenicity of the Abeta (1 …

Amyloid-Beta ‘Oligomers’ May Be Link to Alzheimer’s Dementia

Much evidence points to the involvement of the protein amyloid-beta (A-beta) in causing Alzheimer’s disease, but researchers increasingly are shifting their suspicions away from the large and insoluble aggregates of A-beta seen in patients’ brains at autopsy or in brain-imaging studies.

Amyloid β-Protein (Aβ) 1–40 But Not Aβ1–42 Contributes to ...

In the rat brain, soluble Aβ 1–40 and Aβ1–42 formed aggregates, and the Aβ1–40 but not the Aβ1–42 aggregates showed Congo red birefringence. Electron microscopy revealed that the Aβ1–40 aggregates contained fibrillar structures similar to the amyloid fibrils of AD, whereas the Aβ1–42 aggregates contained nonfibrillar amorphous material.

More Evidence Ties Aβ Strains to Distinct Pathologies ...

Jul 09, 2014· The second stone compares Aβ aggregates isolated from Alzheimer’s brains. In human brain, mutant Aβ folds differently than wild-type, and causes a distinct pathology when seeded into transgenic mouse brain, the authors found.
