Allosteric stabilization of the amyloid-β peptide hairpin by the fluctuating N-terminal.

Immobilized ions modulate nearby hydrophobic interactions and influence molecular recognition and self-assembly. We simulated disulfide bond-locked double mutants (L17C/L34C) and observed allosteric modulation of the peptide's intra-molecular interactions by the N-terminal tail. We revealed that the non-contacting charged N-terminal residues help the transfer of entropy to the surrounding solva...

5-Hydroxycyclopenicillone Inhibits β-Amyloid Oligomerization and Produces Anti-β-Amyloid Neuroprotective Effects In Vitro.

The oligomer of β-amyloid (Aβ) is considered the main neurotoxin in Alzheimer's disease (AD). Therefore, the inhibition of the formation of Aβ oligomer could be a target for AD therapy. In this study, with the help of the dot blotting assay and transmission electronic microscopy, it was have discovered that 5-hydroxycyclopenicillone, a cyclopentenone recently isolated from a sponge-associated f...

Common molecular mechanism of amyloid pore formation by Alzheimer’s β-amyloid peptide and α-synuclein

Calcium-permeable pores formed by small oligomers of amyloid proteins are the primary pathologic species in Alzheimer's and Parkinson's diseases. However, the molecular mechanisms underlying the assembly of these toxic oligomers in the plasma membrane of brain cells remain unclear. Here we have analyzed and compared the pore-forming capability of a large panel of amyloid proteins including wild...

Amyloid-β and Astrocytes Interplay in Amyloid-β Related Disorders

Amyloid-β (Aβ) pathology is known to promote chronic inflammatory responses in the brain. It was thought previously that Aβ is only associated with Alzheimer's disease and Down syndrome. However, studies have shown its involvement in many other neurological disorders. The role of astrocytes in handling the excess levels of Aβ has been highlighted in the literature. Astrocytes have a distinctive...
