prions and Alzheimers disease

Alzheimer’s disease yield is associated with an abnormal build-up of amyloid-β (Aβ) peptides( 40-42 amino acids length) in the brain. Small, soluble aggregates of A β-A β oligomers – impair memory by disrupting memory-related functions of synaptic junctions between neurons. Lauren et al in Nature show that the prion protein might mediate the pathogenic effects…
