Numerous plant viruses contain both the VGGVV and other matching beta-amyloid sequences. Plant viruses are generally considered as benign or unable to infect humans.

In this figure, panel A represents standards, i.e., two synthetic peptides standards, VGGVV and VGGVVIA, which were co-injected. Panels B and C represent analyses of brain amyloid from two different patients, with different ratios of Aβ40 : Aβ42.

2007年5月2日 · Using confocal microscopy and flow cytometry with fluorescently labelled Aβ, we demonstrate a correlation between the aggregation propensity of the Alzheimer amyloid peptides and their neuronal cell surface association.

2023年5月17日 · We identified that the di-glycine region of Aβ 36-40 (sequence VGGVV) exhibits the most profound change in response to cholesterol compared with other segments, explaining how the presence of cholesterol affects the γ-secretase cutting site.

2010年10月1日 · The vascular or parenquimal origin of senile plaques was determined using specific polyclonal antibodies reactive for epitopes VGGVV or GVVIA of the Aβ40 and Aβ42, respectively. We found in the gray matter of SAD and FAD samples a sub-set of amyloid plaques positive for IDE which partially co-localized with Aβ42 and Aβ40 deposits ( Fig. 4 A ...

In order to characterize the ensemble of Aβ 1–40 peptide structures in the membrane environment, we have investigated the structure of monomeric Aβ 1–40 peptide (DAEFR HDSGY EVHHQ KLVFF AEDVG SNKGA IIGLM VGGVV) in an implicit membrane environment using replica-exchange molecular dynamics (REMD) simulation. 60 The structures are described ...
