Descripción general

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.

Aplicación

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.

Acciones bioquímicas o fisiológicas

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.

Alzheimer's disease (AD) is a debilitating neurodegenerative disorder characterized by increased β-amyloid (Aβ) deposition and neuronal dysfunction leading to impaired learning and recall. Ageing, heredity, and induced oxidative stress are among proposed risk factors. The increased frequency of the disease
