Amyloid-β
β-amyloid peptide; Aβ; Abeta
Amyloid-β (Aβ) denotes peptides of 36–43 amino acids that are crucially involved in Alzheimer's disease as the main component of theamyloid plaques found in the brains of Alzheimer patients. The peptides result from the amyloid precursor protein (APP), which is being cut by certain enzymes to yield Aβ. Amyloid-β molecules can aggregate to form flexible soluble oligomers which may exist in several forms. Amyloid-β peptide is due to overproduction of Aβ and/or the failure of clearance mechanisms. Amyloid-β self-aggregates into oligomers, which can be of various sizes, and forms diffuse and neuritic plaques in the parenchyma and blood vessels. Amyloid-β oligomers and plaques are potent synaptotoxins, block proteasome function, inhibit mitochondrial activity, alter intracellular Ca2+levels and stimulate inflammatory processes. Loss of the normal physiological functions of Aβ is also thought to contribute to neuronal dysfunction.

Homogentisic acid
0 ImagesHomogentisic acid is an orally active, blood-brain barrier-permeable amyloidogenic compound that functions as both an amyloid component and a pigment precursor. Accumulation of homogentisic acid downregulates tight junction proteins (such as claudin-5, occludin, ZO-1) and impairs blood-brain barrier integrity. Homogentisic acid and its oxidation product benzoquinone acetic acid not only induce the aggregation and fibrosis of multiple proteins (such as Aβ1-42, α-synuclein, SAA, Transthyretin (TTR), atrial natriuretic peptide), but also trigger oxidative stress, damage to the Wnt/β-catenin pathway, and neurotoxicity, leading to ochronosis pigment deposition and synaptic dysfunction. At specific concentrations, homogentisic acid exerts no cytotoxicity or genotoxicity on human peripheral blood lymphocytes, and even counteracts the genotoxicity induced by Irinotecan (HY-16562). Homogentisic acid serves as an important tool molecule for investigating the mechanisms of diseases including ochronosis, secondary amyloidosis, Alzheimer's disease, and colorectal cancer.
