The influence of spin-labeled fluorene compounds on the assembly and toxicity of the aβ peptide. [PDF]
PLoS ONE, 2012 The deposition and oligomerization of amyloid β (Aβ) peptide plays a key role in the pathogenesis of Alzheimer's disease (AD). Aβ peptide arises from cleavage of the membrane-associated domain of the amyloid precursor protein (APP) by β and γ secretases.
