Abstract

In the prion diseases, neurodegeneration is preceded by the accumulation of the disease-associated isoform of the prion protein (PrP). In the present study, neurones treated with three different phospholipase A2 inhibitors were resistant to the toxic effects of PrP peptides or a synthetic miniprion (sPrP106). Phospholipase A2 inhibitors also protected neurones against a toxic peptide found in Alzheimer's disease (amyloid-beta1-42). Further studies showed that neurones pre-treated with platelet activating factor (PAF) antagonists were equally resistant to PrP peptides or amyloid-beta1-42. Moreover, both phospholipase A2 inhibitors and PAF antagonists reduced the activation of caspase-3, a marker of apoptosis, and the production of prostaglandin E2 that is closely associated with neuronal death in prion or Alzheimer's diseases
