Using a simple in vitro amyloidopathy CAD neuronal model, infrared (IR) 1068 nm light treatment (5 x 3 minutes) was investigated as a novel neuroprotection strategy. Synthetic human β-amyloid(1-42) peptide was subjected to aggregation in a test-tube, and shown to form fibrils of a range of sizes (individually ~10 μm), which compromised the cellular nuclear integrity of CAD cells in culture, and...
Corneal stromal dystrophies are a group of genetic disorders that may be caused by mutations in the transforming growth factor β-induced (TGFBI) gene which results in the aggregation and deposition of mutant proteins in various layers of the cornea. The type of amino acid substitution dictates the age of onset, anatomical location of the deposits, morphological features of deposits (amyloid, am...
Alzheimer's disease is the prevalent cause of premature senility, a progressive mental disorder due to degeneration in brain and deposition of amyloid β peptide (1-42, a misfolded protein) in the form of aggregation that prevails for a prolonged time and obstructs every aspect of life. One of the primary hallmarks of the neuropathological disease is the accretion of amyloid β peptide in the bra...
The applications of supramolecular metal-peptide assemblies as catalyst or precursor have recent attracted increasing attentions. In this work, a fragment the amyloid β-peptide, NH2-KLVFF-COOH, was assembled into nanofilms with encapsulated Pd, Pt and Au nanoparticles (NPs) via one-step room temperature electron induction method. effects building block, intermolecular interaction, driving force...
The dipeptidyl peptidase-4 (DPP-4) inhibitor sitagliptin is an attractive therapy for diabetes, as it increases insulin release and may preserve β-cell mass. However, sitagliptin also increases β-cell release of human islet amyloid polypeptide (hIAPP), the peptide component of islet amyloid, which is cosecreted with insulin. Thus, sitagliptin treatment may promote islet amyloid formation and it...
