General description
Amyloid β (Aβ) 1-42 is the major Aβ species in the amyloid plaques that develop in the case of Alzheimer′s disease (AD). It has a cross-β structure with parallel, in-register β-sheets.
Application
Amyloid β 1-42 rat has been used as an amyloid β (Aβ) oligomer in intracerebroventricular (ICV) injection/intra-hippocampal infusion to establish the Alzheimer′s disease (AD) model in rat.
Biochem/physiol Actions
Amyloid β 1-42 forms amyloid fibrils more readily compared to Aβ(1–40), in vitro. Aβ1-42 injections are known to cause brain dysfunction indicating learning and memory deficits. Amyloid β (Aβ) refers to peptides derived from amyloid precursor protein that vary in length from 37–43 amino acids. Aβ(s) peptides, their peptide fragments, and mutated fragments are used to study a wide range of metabolic and regulatory functions including activation of kinases, regulation of cholesterol transport, function as a transcription factor, and regulators of inflammation. Aβ(s) peptides and their peptide fragments are also used to study oxidative stress, metal binding, and mechanisms of protein cross-linking in the context of diseases such as Alzheimer′s disease and neurodegeneration.

Ginkgolide B (GB), the diterpenoid lactone compound isolated from the extracts of Ginkgo biloba leaves, significantly improves cognitive impairment, but its potential pharmacological effect on astrocytes induced by β‑amyloid (Aβ)1‑42 remains to be elucidated. The present study aimed to investigate the

Alzheimer's disease is pathologically characterized by the presence of senile plaques and neurofibrillary tangles in the central nervous system. Amyloid β-protein is toxic to neurons and induces phosphorylation of Tau protein, which accumulates in paired helical filaments and leads to

One of the signs of Alzheimer's disease (AD) is the formation of β-amyloid plaques, which ultimately lead to the dysfunction of neurons with subsequent neurodegeneration. Although extensive researches have been conducted on the effects of different amyloid conformations such as
