dc.description.abstractA major hallmark of Alzheimer's disease (AD) is the formation of toxic aggregates composed of the β-amyloid peptide (Aβ). Given that Aβ peptides are known to co-localize within mitochondria and interact with 17β-HSD10, a mitochondrial protein expressed at high levels in AD brains, we have investigated the inhibitory potential of 17β-HSD10 against Aβ aggregation across a range of physiological conditions. The fluorescence self-quenching (FSQ) of Aβ(1-42), labelled with HiLyte Fluor 555, was used as a sensing strategy to evaluate the inhibitory effect of 17β-HSD10 under well-established conditions to grow distinct Aβ morphologies. Our results indicate that 17β-HSD10 preferentially inhibits the formation of globular and fibrillar-like structures but has no effect on the growth of amorphous plaque-like aggregates at endosomal pH 6. This work provides insights into the dependence of the Aβ-17β-HSD10 interaction with the morphology of Aβ aggregates and how this impacts enzymatic function.
