This thesis investigates the interaction between Alzheimer's disease amyloid-β peptide (Aβ) and the small heat shock protein αB-crystallin (αBC). By exploiting the range of biophysical techniques, it was demonstrated that αBC alters Aβ fibril structure, preventing a compact conformation and promoting a polymorph with a dynamic N-terminus. This modification impacts fibril properties. Solid-state NMR was used to structurally characterize both polymorphs. αBC interactions with Aβ40 species were studied using solution-state NMR and super-resolution fluorescence imaging.
