Amyloid-? oligomers are correlated with Alzheimer’s disease progression and suppress synaptic plasticity1, 2, 3. Through unbiased expression cloning, we identified cellular prion protein (PrPC) as an amyloid-? oligomer binding protein4. PrPC was necessary for acute . . . → Read More: Laurén et al. reply

The prion protein as a receptor for amyloid-beta

See the paper

Reply to Lauren et al 2009

Kessels HW, Nguyen LN, Nabavi S, Malinow R.

Increased levels of brain amyloid-beta, a secreted peptide cleavage product of amyloid precursor protein (APP), is believed to be critical in the aetiology of Alzheimer’s disease. Increased amyloid-beta can cause synaptic depression, reduce the number of spine protrusions (that . . . → Read More: The prion protein as a receptor for amyloid-beta

The NAD-dependent deacetylase Sir2 was initially identified as a mediator of replicative lifespan in budding yeast and was subsequently shown to modulate longevity in worms and flies1, 2. Its mammalian . . . → Read More: A novel pathway regulates memory and plasticity via SIRT1 and miR-134
